this is bbc news. the headlines at 7pm: police investigating the suicide attack in manchester say they've got hold of a "large part" of the terror network behind the bombing. they are very significant, these arrests. we're very happy we've got our hands around some of the key players that we're concerned about. but as i say, there's still a little bit more to do. with the security level still at critical, armed police are in force at the start of the bank holiday weekend as more than 1,000 public events take place. also this hour: an election row asjeremy corbyn links british military intervention abroad to terrorist atrocities at home. the conservatives call his comments crass and ill timed, but the labour leader insists there must be a new approach to foreign policy. we must be brave enough to admit that the war on terror is not working. we need a smarter way to reduce the threat from countries that nurture terrorists and generate terrorism. jeremy corbyn has said that terror attacks in britain are our own fault

and he's chosen to do that just a few days after one of the worst terrorist atrocities we have experienced in the united kingdom. an influential think tank accuses both the conservatives and labour of not being honest with voters about the consequences of their economic plans. and managing expectations... will it be a win for conte‘s chelsea or wenger‘s arsenal in this weekend's fa cup final? good evening and welcome to bbc news. britain's top counter terrorism officer says they have captured "a large part" of the terror network involved in the manchester arena attack, where 22 people died. mark rowley said "immense progress" had been made in the investigation, but there were still important lines

to pursue and arrests to be made. it comes ahead of a bank holiday weekend where more than 1,000 public events are taking place. the terror threat remains at a critical level, which means another attack may take place imminently. our home affairs correspondent daniel sandford reports. an already vast investigation, still expanding. each day, counter—terrorism detectives raid more properties in manchester, cutting through the shutters at this barbershop. the shop was run by a cousin of the manchester bomber. he was arrested earlier in the week, with at least one of his brothers. police also raided another house in the middle of the night, bringing the number of people in custody to eight, all men, mostly libyan, and aged between 18 and 38. very significant arrests. we are very happy we have our hands around some of the key players

we are concerned about. there is still a little bit more to do. the bomber, salman abedi, came back to manchesterfrom libya last week. renting a flat in this block, he had already bought many of the ingredients for his lethal device. it was here that he spent his last weekend, putting his bomb together, making the final preparations to attack a concert full of teenage girls. detectives say they have made very significant finds and crucially believe they have captured a large part of his terrorist network. we have hundreds of officers working on this investigation from across the national counter—terrorism policing network. we have seized thousands of exhibits which are being assessed. it is fair to say there has been enormous progress with the investigation but still an awful lot of work to do. i understand the finds include bomb—making chemicals

but because of concerns about what might still be out there, the threat level remains at critical. the home secretary saying people could expect much higher security at the 1,300 events across the country this bank holiday weekend. i hope they will take comfort from that, be able to feel more secure, because we must not let this terrible terrorist incident impact on our lives. let's carry on this bank holiday weekend with our families and friends. already, people getting away for the weekend can expect to find armed officers patrolling trains outside london for the first time. as the investigation continues, we are learning more about salman abedi's father, who was detained in libya this weekend. he is believed to have had strong connections to abu qatada, who was suspected of being a senior al-qaeda figure in london. this businessman says that the bomber‘s father was always seeing abu qatada in the capital. he was one of abu qatada's supporters, he told the bbc.

whenever he went to london, they would meet up. detectives do not pretend to have the full picture yet. they are growing in confidence but for now, going into one of the most important weekends of the summer, everyone is nervous. the labour leaderjeremy corbyn has made a controversial speech linking british military action abroad to terrorist attacks here at home. mr corbyn said the ‘war on terror‘ is not working and that a different approach to uk foreign policy is needed. he was speaking as election campaigning resumed after monday's attack in manchester. this evening, the prime minister criticised his remarks in both their message and theirtiming. joining us from westminster is our political correspondent chris mason. just talk us through whatjeremy corbyn said. and the reaction. politics returns, argument returns,

and policy returns. but politics is being looked at, through the prism of manchester. labour decided that in this big speech, jeremy corbyn wa nted in this big speech, jeremy corbyn wanted to reflect on what has happened. some have questioned the timing of this intervention, some have also questioned the nature of it. it is up to you to make your mind up. this is the essence of the argument. we must be brave enough to admit that the war on terror is not working. we need a smarter way to reduce the threat from countries that nurture threat, generate terrorism. that is why i set out the

policy on counterterrorism. it is an increasingly dangerous world. we must support armed forces, and diplomats. engage with the world in a way that reduces conflict, bills peace and security. we have to be absolutely clear. jeremy corbyn was not trying to find any sort of excuse not trying to find any sort of excuse for the terrorists, instead trying to get an analysis, explanation for why acra one could act in particular circumstances. the reaction has been furious. both from some in his own party, and indeed from the conservatives. this reaction from the prime minister at the g7 summit, italy. what has happened today, i have been here at

the g7, happened today, i have been here at the 67, working with other international leaders to fight terrorism. at the same time, jeremy corbyn has said that these terror attacks in britain are wonderful. and he has chosen to do that after one of the worst atrocities we have experienced in the united kingdom. i wa nt experienced in the united kingdom. i want to make one thing very clear to jeremy corbyn and to you, there can never be an jeremy corbyn and to you, there can i'ievei’ be an excuse jeremy corbyn and to you, there can never be an excuse for terrorism. no excuses never be an excuse for terrorism. no excuses for what happened in manchester. we are expecting to hear jeremy corbyn in this interview with andrew newell, what is he going to be expected to say? the focus on trident? yes. more evidence that politics is returning, andrew newell and these interviews back on. he spoke to theresa may on monday

evening. then we had the suspension, during the course of the week. tonight, it isjeremy corbyn using half an hour of scrutiny on printing television from andrew newell. and the particular focus on the issue of the particular focus on the issue of the nuclear weapons system. and the reason we the nuclear weapons system. and the reason we had that focus, a contradiction at the heart of labour at the moment. the manifesto commits the party to the renewal of the trident system, butjeremy corbyn has been a lifelong opponent. this exchange, worth a watch. do you support the renewal of trident?m is there... that is not what i asked. i voted against the renewal, everybody knows that because i wanted to go in a different direction. that decision has been taken. can you tell the british people tonight that you support? taken. can you tell the british people tonight that you support7m has been agreed by parliament. do you support that? my opinions on

nuclear weapons, well known. i want to achieve the multi—disarmament, the treaty. you do not support that? i support the nuclear free world, and we have mentioned those serious threats. we need the simple answer. you cannot say to the british people tonight that i, jeremy corbyn, will support the renewal of trident?m is in the programme. we are going to pass through that, and that the same time, negotiate the multilateral disarmament, listen, do we really want to live in a world when we have got these dangerous? why do you not see that you are against this? this is the position that we adopt as a party. is this going to include

trident? it is going to look at... you are going to ditch it! fit is going to look at the totality. many senior people in the armed forces are going to also want us to focus as well on the issues i mentioned, cyber security. we want to clarify this. you cannot tell the british people that you are in fever of the renewal of trident but you want the defence review, that is going to include trident. it is going to include trident. it is going to include the role of nuclear weapons. exactly. listen. it is in the programme. i know that dear viewer, your devotion to the channel means that you are not going to be going to bbc one to watch that... you can get that under iplayer later. nicely

done! and you can watch andrew neil's full interview with jeremy corbyn here on the bbc news channel at half past midnight. all of those who died in monday's attack have now been named. the 22nd victim was 15—year—old megan hurley. she was from halewood in merseyside. the bombing happened at the concert, at the manchester arena, from the p0p at the manchester arena, from the pop singer, ariana grande, and she said that her thoughts are with the city. she is going to return to the city, for a benefit concert. danny savage reports from manchester now, on a community grieving for lost family and friends. in central manchester today, people queued to buy flowers in remembrance of strangers. many are at a loss about what's happened, but have to do something. it was inconceivable to try and understand how

the families are feeling, especially of the children. it's just shocking. i've been a coronation street superfan my entire life. 29—year—old martyn hett was one of those murdered on monday night. the outgoing coronation street superfan was well—known online. as these possibilities got less and less and less, you still had some hope there would be something, and when you actually got the call that actually confirmed that he had died in this terrible explosion, it's, it's indescribable. your world just collapses, terrible. the final and 22nd victim to be named today was 15—year—old megan hurley. her brother was seriously injured too. a note on the family business only hints at the true enormity of the tragedy. a picture of the horror which faced the first responders has emerged too. 0n the right here, is paramedic adam williams.

he is worried about the long—term effects on him and his colleagues. that is a big concern for all of us. possibly myself, there will be some permanent scars there, emotionally. and i do worry that my colleagues will suffer the same. there is a very sombre and respectful atmosphere here. it may be four days since the atrocity, but that really is just the blink of an eye, and people here are stilljust trying to come to terms with what happened and coming to pay their respects. 22 lives lost, countless others changed forever. families left with just memories of those who will never come home. let's cross now live to clare fallon, who's in st anne's square in manchester. what an extraordinary sight behind

you? absolutely. and this evening, people still coming along, laying flowers, pausing for a moment to reflect on the events of this week. also to remember the 22 people killed in the attack at the manchester arena on monday evening. just on the other side of the square, multi faith vigil, reading prayers, and getting spontaneous rounds of applause. until today people have not been able to get close to the manchester arena because of the police cordon. this has become the focal point for people wanting to, one and pay tributes. as for the police investigation, that is clearly ongoing, police have said they have made significant arrests, and finds, immense progress. and here, the

investigation is not the focus. people just looking to come together asa people just looking to come together as a group, i think, and remember the people who died. this sea of flowers, growing all the time. at the other end, people have been writing messages on paving stones, with chalk. and you can see some people, trying to find some spare space. this city knows that things need to return to some form of normality, and this weekend and sporting events going on at the city centre, the city games. and organisers were adamant that this should happen, despite the events of tuesday, but when you are here, it still seems as though we are still a

fair way away. thank you. back now to the g7 summit in sicily. the group of industrial nations have agreed to do more to fight terrorism and extremism at their summit in sicily in italy. theresa may said the battlefield was moving online and that the g7 had agreed a range of steps to encourage internet companies to remove extreme content. we can now speak to our diplomatic editorjames landale in taormina. a few leaders turning up for their first g7? a new era. four of the seven, new. and all eyes on donald tron. we know that he believes in bilateralism, american doing deals with countries, one—on—one. the g7 is collective organisation and i think the leaders have been cautious

by slowly but surely exploring how far they can push him on issues when they have got this agreement, climate change, international trade, to see how far they can push them to get him to change his mind without putting in so far that he disagrees. and ending up in a perhaps less than diplomatic result when this summit ends tomorrow. what have been the most pressing issues discussed? today, they have been discussing terrorism and on that they have been pretty unanimous after the events of manchester. they have a a package of measures, some of which on theresa may's agenda. that means more action, trying to put pressure on internet companies to do more to identify and take down, block extremism material. trying to do more to share experiences with other countries in the middle east to stop fighters leaving the region.

especially now that islamic state is losing territory. tackling terrorism financing. they have released a statement, talking about manchester and on other issues for example, climate change, the united states government's position on the 2050 paris deal to tackle climate change is still in play. have theresa may and macron chatted? some reports that he snubbed her?!|j and macron chatted? some reports that he snubbed her?! i do not think so. that he snubbed her?! i do not think so. theresa may had many meetings. sitting down, notes being taken, a proper conversation. this is the first thing they have the chance to do this since he was elected. so

much to talk about, and obviously acra one. they obviously stated positions, mainly that theresa may monster discuss the divorce and future relationship with the european union. macron represented france and the rest of the european union, that these things have got to be done one thing at a time. it was not a snub. theresa may for something justin trudeau and the american president, not to talk about treaty was after brexit, but both reaffirming the importance of the united kingdom and united states increasing mutual trade after brexit. the usual things being discussed at the summit, like this. thank you. security has been one of the key issues, and report on

another attack on coptic christians in the gym. many have been injured after the gunmen opened fire on a pass close to cairo. the community, that makes up about 10% of the population has suffered several major attacks in the past six months. and we can take a look at some of the other stories. irish police are investigating the death of a baby girl who was left in her father's car for several hours. it's thought she may have died from heatstroke. she was found unresponsive in the vehicle in dundrum in county tipperary, on one of the hottest days of the year. a student who made a bomb filled with ball bearings and left it on a tube train has been jailed for 15 years. damon smith put his homemade device into a rucksack and left it on a jubilee line train in october 2016. the 20—year—old claimed it was a prank but was found guilty of possession of an explosive substance with intent. sir cliff richard and south yorkshire police have settled a legal fight over reports

naming him as suspected sex offender. the singer sought damages from the force, and the bbc, over media coverage of a police raid on his home in 2014. he was investigated over historical sexual assault allegations, which he denied. the case was dropped last year and south yorkshire police has apologised wholeheartedly. the bbc is still disputing the singer's claim for damages. neither the conservatives nor labour are presenting an "honest set of choices" to the public over their tax and spending plans — that's according to an influential think tank. the institute for fiscal studies has criticised both parties‘ election manifestos, saying they fail to address the country's long term challenges. here's our economics correspondent andy verity. neither the conservatives nor labour

are being honest over their tax and spending plans — that's according to economists from an influential think—tank. the institute for fiscal studies has criticised both parties‘ policy proposals, saying they fail to address the long—term challenges facing the country. what about the conservatives? they have planned to continue with austerity, and the institute for fiscal studies have said it is going to bea fiscal studies have said it is going to be a big risk that you could get serious damage to public services. under labour, the tax reasons would get money but the danger is that they would not get the money that they are planning to spend. the squeeze they are planning to spend. the squeeze on public services may not be deliverable. both parties have said they want more fearless, but the ifs have said they are not being honest about that. the conservative plans to be fair across generations. they want to scrap the trouble of meaning state pensions go up by 2.5% each year. the ifs has said those

will not raise much money. just one billion and that is not going to reason much over the next five yea rs. reason much over the next five years. what about labour? they said they are about the many, not the few. scrapping tuition fees. but the ifs said that benefits the wealthiest segment going to university, and also cutting in work benefits. that could harm some of the working families across the country. what about other questions? the tax burden. as a share... it is going to be the highest it has been since the 1940s. the conservatives also have some questions to answer about emigration plans. the institute for fiscal studies said it will damage the economy of the hit those targets, and 6 billion laced tax—free if you coming. those are the views of the ifs. an important archive, showing

remarkable footage of explorers from 100 years ago has been found and bbc news has been given exclusive access. it shows the frozen mountains of the himalayan ‘s, to the searing deserts, discovered by adventurous. this is the first ever view of mount everest from the air. it was shot in 1933 by a group of pilots who risked their lives to help create an aerial map of the mountain. the film is part of the royal geographical society's archive. it includes the very first attempt to climb to the top of mount everest, in 1922. the climbers are treated to a ritual dance at a tibetan monastery. around the dancers' waists are aprons made from a lattice of human bones. the cameraman was captainjohn noel. his daughter recalls how her father filmed the expedition. he had a purpose built tent he'd taken with

him to base camp. and at night, using water from the glaciers and yak dung as a source of heat, he processed 10,000 feet of film on themountain. conservation specialists are painstakingly restoring 138 films of some of britain's greatest explorations frame by frame. one of them is of a young army officer crossing the vast expanse of the libyan desert by motorcar. ralph bagnold and his friends drove thousands of miles for weeks on end into the blistering heart of the libyan desert. his son has read stories about these incredible expeditions, but it's the first time he's seen them. that's my father driving now. he even wrote scientific papers about how sand moves. his research is helping space agencies to this day, to develop rovers that can drive across the surface of mars. to see this film makes me feel very proud of him. i'm in awe of what he managed to do.

we can all now relive these extraordinary adventures, stories from a bygone age when the world held so many mysteries. and we can retire this idea that british foreign policy has been an impact on incidents here. theresa may has called on the g7 and internet companies to do more to tackle extremist content. we can speak to adam dean, from the terrorism think tank. joining us on webcam. thank you forjoining us. how accurate and assessment is jeremy corbyn‘s opinion that foreign policy, british foreign policy, will have an impact overseas and at home?

0bviously, have an impact overseas and at home? obviously, an impact but in terms of radicalisation and extremism, this sounds like a comment from someone who does not understand the radicalisation process. many factors involved in radicalisation. what to focus on foreign policy at the expense of ideology is absurd. but he has got a point. to what extent? we can argue that foreign policy and the impact of forces in the foreign middle east could be a necessary condition. but what we saw in manchester, what we saw, this horrendous crime, cannot be explained by simply saying that foreign policy was behind this. the radicalisation process, what it does is that it takes grievances, twists them, for the extremist agenda. that

is the only way we can understand that somebody would commit such horrendous crimes. what is the ideology that these young men are buying into? it would be apt to quote isis. last year. in the online magazine, they said we hate you, first and foremost because you are disbelievers. kozlov was —— because of those secular values. what about the importance of social media. theresa may has been calling on internet companies to do more to address the worst offences that we have seen? unfortunately, social media is an optimal tool for extremist. a number of reasons for that. the spread of information, the contagion, only in a couple of years

isis weren't able to spread that ideology on the internet without any time for loss to try to provide bottles, counterarguments. isis, terrorist organisation to have an industrial approach to the internet. also, anonymity. before, if an extremist, before the advent of social media, it was someone who was durie is about extremism than they would have to physically go and engage with an extremist. a terrorist member. but that physical barrier has now been removed. somebody canjust barrier has now been removed. somebody can just out of curiosity connect somebody and then what can happen is that that accrue to process ca n happen is that that accrue to process can happen. it is the optimal method of recruitment. how to counter the propaganda? has sophisticated doesn't need to be? we

need to play isis at their own game. they are real masters on how to use social media and social media content. it's not just social media and social media content. it's notjust about shutting down. we have seen the giant, social media giants like twitter shutting down hundreds of thousands of extremist accounts. it's not just thousands of extremist accounts. it's notjust that. we need to provide counter narratives in the form of social media and social media content in order to rebut their claims and arguments. it's important that that counter narrative is there, so that we can win this battle. thank you very much for your time. the weather now with helen. another hot day, hotter than yesterday, about 1 degrees another hot day, hotter than yesterday, about! degrees higher than yesterday, particularly in north—west wales and the north west of scotland. many places have seen temperatures in the mid—20s or

above. it's no surprise, we have seen stronger than expected sunshine, an abundance of sun—dried, barely a cloud. through the evening, the showers are starting. that continues the start of the breakdown through the evening and overnight. another uncomfortably warm night for most. some sea fog rattling around the shore, so different type of day here. a band of showers and thunderstorms go eastwards, drying up thunderstorms go eastwards, drying up behind with more cloud. but every time, when you add the heat of the day to a weather system, there could be torrential downpours around southern scotland, northern england, perhaps lincolnshire as well. the heat is expected to remain with us. there is more on the warnings on the website. hello. this is bbc news. the headlines. the head of the national counter terrorism unit has said that police have taken hold of a ‘large part‘ of the manchester terror network but that ‘more arrests' are likely.

with the security level still at critical, armed police are in force at the start of the bank holiday weekend, with more than 1,000 public events taking place. jeremy corbyn says he will change british foreign policy if he becomes prime minister, to try to reduce the risk of terror attacks in the uk. the institute for fiscal studies says that neither of the two main parties are presenting voters with an honest set of choices in their election manifestoes. the political parties are resuming campaigning after the manchester attack. this market is bathed in sunshine today, i'm here to talk election politics and reflect on this week's dramatic events in

manchester. we need a proper opposition. the only opposition i'm afraid has to come by the labour party. is this for manchester? of course. at this particular moment in time, that is more important than the election. this is the amber valley constituency, classic middle england seat. it swung to the tories seven england seat. it swung to the tories seve n yea rs england seat. it swung to the tories seven years ago. other voters in the mood to swinging again?|j seven years ago. other voters in the mood to swinging again? i voted conservative my whole life. and i think now, i'm leaning towards labour. ijust think we need a change. i've been through austerity measures myself in a previousjob, andl measures myself in a previousjob, and ijust think we need a change. and going against all principles, because i've always been labour, but i think the only person who can take us i think the only person who can take us forward is theresa may. why? i just don't like jeremy corbyn. in

last's referendum campaign, just over 60% of this constituency voted to leave the eu. just over 39% wa nted to leave the eu. just over 39% wanted to remain. i've always done that, always will. no reason why. why before the conservatives? i've been a union official for quite a few years, i'm a labour member, but ifind few years, i'm a labour member, but i find corbyn completely inflatable. blue, 0k. why the conservatives.” think she seems the strongest person to be prime minister. so you like a pro—business voice with a social conscience. yeah. and you're not getting that with mrs may? definitely not. and voting labour for the nhs. i definitely not. and voting labour forthe nhs. ithink definitely not. and voting labour for the nhs. i think there are more for the nhs. i think there are more for the nhs. i think there are more for the working class person. picture is emerging that for the two

main parties, labour have got the edge here. but it will be no surprise that at the end of this week, people's thoughts are on the people of manchester. here is a list of the candidates standing in the amber valley constituency. more details about the campaign and the election on the bbc website. as education shapes up to become a key issue in the general election, schools in norfolk, suffolk and essex could face cuts totalling £1118 million over the next three years. campaigners, parents and children have held a day of action to highlight the funding problems facing our schools, and to get the political parties to promise to do more, as bbc look east's ian barmer reports. this is a junior school near norwich. 440 pupils, rated good by 0fsted, with a budget of £1.7 million a year. but headteacher paul stanley is worried. notjust about his school, but all schools. he's written to parents ahead of the general

election, telling them they are importance of education funding. it says school finances are in a dreadful state. you hear the government saying so much more money is coming into schools, the costs are so much the numbers are so much more. actually, it amounts to a cut for most schools. there seems to be almost a resentment that putting money into schools is somehow wasted, or has to be justified. it's an investment in young people's future, and surely that's worth finding the money for. the school could be facing a yearly budget cut of £50,000 despite something called the national funding formula. the last conservative government planned it to make school funding fairer. many will be taken from largely urban areas where schools have been getting more, and given to largely rural areas, where historically they've received less. it's in the conservative manifesto and if it's

brought in, it will mean more cash for our schools. in suffolk an extra 2.7%, or £10.4 million per year. in essex, an extra 2.6%, that's £20.2 million. and in norfolk, 1% more, that's £4.7 million. in total, £35.3 million. but that money will be spread around thousands of schools, and for many, it won't make up for rising bills. at this academy in harlow, they could lose £750,000 a year. i'll either have to leave because they've asked me to do something and not willing to do, or they'll get rid of me. because i'm not willing to do that. i'm not willing to come into this profession that i love so much and ruin children's lives. but the head of the inspiration trust academy chain in norfolk and suffolk says efficiency is the key. the last 20 years, school funding has doubled. and i think what we need to do now

is the really efficient and work together as a group. inspiration trust is 13 schools, and we share everything so that we can be really efficient with contract, with finance. so that money can go to the front line and education standards can stay really high. funding, standards, they matter to 418,000 pupils across norfolk, suffolk and essex and their families. we'll know what's in store for our schools over the next five years on the 9th ofjune. some of the hardest to reach might be the rural voters of cumbria — where farming and tourism are vital to the economy. the bbc‘s north east and cumbria political editor richard moss has travelled across the county to find out about the issues concerning people there. sale day at longtown livestock mart, right on the northern edge of england. cumbrian farmers' main concern today maybe the cost of a bull, but another b word dominates the election — brexit.

farmers are like everybody else in the country, they are in a period of uncertainty. but i still think are of the firm belief that they are better off in their own independent country than they are as part of the eu. certainty is in short supply, the farmers here are searching for answers on how leaving the eu will affect their financial support or ability to export. if we had an interruption in the ability to export, that would be our trade is completely finished. it would probably wipe a year's profit out. we have to have a good deal, and we need a strong negotiator for it. my son is farming, and my grand daughter and grandson, they are farming, and i've got a great granddaughter who just left school, and she wants to farm. i'm worried for them. ijust want stability and a bit of honesty from politicians, but that's like hen's teeth. 40 miles away in keswick, and locals also want answers. tourists are the town's lifeblood and give 22—year—old josh his job,

but the town's popularity poses problems he would like to see tackled. house prices in this area are absolutely unbelievable. for me to be able to buy a house is really quite hard. i can't fork out the amount of money they want just for a deposit. my friends are all having to move away. it's not easy, that's it. and student lydia finds it tough to afford to even make it to work. i think things like bus prices, particularly for young people trying to travel around... for example, i need to get through to keswick for work, and it's like £10 return, which is too much, really. tour driver andy has his own transport and knows that getting around the county can be a problem. it is an elderly population. when all the visitors have gone, it's very much an elderly population. local access to hospitals in particular, and of course, the roads. we need good roads.

a lot of them have got big holes in them at the moment. on a day like today in surroundings like this, it's hard to believe that anyone in cumbria could have a care in the world, but actually, from the price of land to the cost of a house, voters here do want issues addressed by the politicians after the 8th of june. richard moss, bbc news, in keswick. we'll be discussing the big political moments of the week at 8:30pm on bbc news, when we'll be joined by the independent‘s chief political commentator, and the spectator‘s political correspondent. the police and security services say they're keeping an eye on 3,000 people of interest — and that they have 500 active investigations to deal with. this week's atrocity has again raised questions about government strategy, and whether it has the right powers to deal with those who pose a possible risk. our home editor mark easton reports.

the murder of lee rigby in woolwich, 2013, prompted david cameron to reshape his strategy. the focus was on home grown extremism with public sector workers becoming legally obliged to inform police if they thought someone was displaying extremist behaviour. the government set up an extremism target, counter extremism bill, tough powers against anyone deemed to be an extremist. but the legislation now looks unlikely ever to happen because ministers struggled to define extremism, and concerns the approach fosters suspicion and distrust in largely law abiding muslim communities. the terror attacks in paris in 2015 sent a shockwave across europe. in the uk, ministers responded by announcing an extra 1,900 spies and 1,000 more police firearms officers. we have been building the capability

of police here in the uk to respond. but the number of firearms officers is actually 1,300 lower than 2010. the attack in westminster last march once again focused concerns on keeping track of individuals known to have radical views. there were questions as to why people like the murderer, khalid masood, couldn't be monitored and if necessary detained. security services have 3,000 people under investigation in active operations but only seven people have their movements restricted under special powers. the courts take a dim view of limiting people's freedom if they haven't been convicted of a crime. the dreadful bombing in manchester was followed by claims that cuts to policing may have contributed to the attack — an accusation emphatically denied by the government. ring fenced money for the police's counterterrorism effort has increased over the last few years, from £594 million in 2015/16,

to £675 million now. but that doesn't tell the whole story, because that money comes out of the total police budget. central government money for police has actually fallen 25% since 2010. in greater manchester, police counterterrorism funding is up £6 million but the force says its overall budget must go down £14 million. spotting, monitoring and neutralising the threat from home grown terrorists is partly about resources, of course, but it's also about creating a society where such an ideology cannot breed and thrive. let's speak to sir richard dalton, former british ambassador to libya and iran, now an associate fellow at the chatham house think tank. thank you for waiting so patiently until we got to you. where is the

evidence thatjeremy corbyn is right about our foreign policy having an impact on young people who may be radicalised? first, we need to be clear about what he said and what he didn't say. he didn't say what boris johnson alleged that he was somehow justifying terrorism. nor is he trying to draw attention away from the main focus of combating terrorism, which must be domestic and about countering radicalisation. but what he did say is there is a connection in many people's minds amongst this appalling minority able to contemplate these acts between what britain does overseas, particularly the middle east, and the twisted narratives they put together to justify their appalling acts. to my mind, that is undeniable. first, because islamic

estate make such a connection themselves when publicising the attacks they claim —— islamic state. they say in the case of france that they are responding to france's bombardments of isis targets in syria. but they were responding to france's efforts in north africa, to rollback advances by islamist extremists. secondly, the evidence is that although we don't know the exact motivation of salman abedi, it could be one of three things. first, he may have been taught that it's dreadful to live in our society, in other words that our values, as your previous speaker said, are to be combated. secondly, he might have been taking revenge for a particular act. but we don't know precisely what revenge she might have had in

mind. his sister has suggested it was about the killing of syrian children. well, that is a foreign policy matter. it could be that he was taking revenge for the killing in manchester moss side of a young libyan last year. those all—powerful indications that although as another previous speaker said, the foreign policy element is not a sufficient motive for attacking as in the dreadful way we saw in manchester, in the minds of many extremists. it does form part of their narrative that justifies in their does form part of their narrative thatjustifies in their own minds what they are trying to do. why then have jeremy corbyn‘s what they are trying to do. why then havejeremy corbyn‘s comments and so controversial? i think that the former head of m16 expressed similar views a while back. yes, and the head of m15, the security service,

did warn in the government's confidential debates before the invasion of iraq that it could well end up making us less secure. so i think you have to look to the realm of the current political atmosphere. all we got from our foreign secretary with rex tillerson alongside him from the united states this morning was the kind of spluttering abuse which we are now used to from him, in an attempt to deceive the public about some important political matter. mr corbyn did not seek to justify terrorism and to tell the british public that that's what he was doing and that consequently his speech was monstrous is simply politics, it's simply propaganda. jeremy corbyn has said that if he were to become prime minister, foreign policy would change and the use of military action wouldn't be the same. can you

envisage what that policy might look like? well, he set it out. he said that there should be a legal framework, that there should be a real need and that need in many insta nces real need and that need in many instances in our long history has been when there was a significant threat to our homeland from armed action. which, of course, there was no such threat at the time of our decision to assist the american inui ordering the middle east in 2003, a decision over iraq which has disastrously backfired for the people of iraq. that also leads us to wonder whether in the minds of some jihadis to wonder whether in the minds of somejihadis there could to wonder whether in the minds of some jihadis there could be a connection between attacking the uk and the appalling consequences of what happened in iraq, and what is happening in syria, and where after all we are attacking islamic state. there are 4 million, 4 million

internally displaced people from the conflict in iraq. there are 5 million registered refugees in syria. so apart from the casualties and the deaths, there is a lot for people to worry about and to wonder whether the west really has it in for ms lynn ‘s. whether the west really has it in for ms lynn 's. even if our foreign policy meant that we never went —— has it in for muslims. how do combat that other issue, which is social media? that's that other issue, which is social media ? that's nothing that other issue, which is social media? that's nothing to do with foreign policy, is it? no, but the social media is carrying a message. it's carrying their narrative. it's carrying twisted ideas. actual personal contact i believe, which is where you have to look to the final decision of an extremist to commit an atrocity. we don't know what drew the attack in manchester, but it

could be that contacts he made in libya in his last—minute —— his last visit, a context in the uk that contributed to those decisions. it could be as speakers on bbc programmes have said, it could be his meetings with the tiny minority of manchester's islamic community who conduct meetings outside open places like didsbury mosque in their own private meeting places. and it is there perhaps that his radicalisation took place. the former british ambassador to libya and iran, thank you very much for your time. thank you. mermoz will be heading to big events this weekend. —— many of us.

wherever you go, there is likely to bea wherever you go, there is likely to be a big security presence. here aaron albert square, the very centre of manchester, the scene of that emotional vigil the night after the bombing. here today in the sunshine, it has been transformed into a sporting arena. they have set up pole vault, the long jump competition is going on at the city games. lots of top—level athletes enjoying the event, enjoying the sunshine. among them the london 2012 0lympic sunshine. among them the london 2012 olympic champion greg rutherford, currently leading the long jump, looking like another victory for him. another couple of hundred meters down the road, the sprinters are in action. the likes ofjohnny peacock, the double paralympic champion also running here. security very tight. there are armed guards on each entrance to the square, there are hundreds of police officers on the street. but while

some cities have been forced to cancel some cities have been forced to ca ncel events some cities have been forced to cancel events not only out of respect for those who lost their lives there, but also because of the increased terror threat. manchester it feels has had to make a different decision. after consultation with the police and security services, they have agreed that this city games goes ahead, as does the great manchester run taking place over the weekend. this is another chance and the people of manchester to come together in light of what has happened to them this week. another chance to them to say that sport yes isa chance to them to say that sport yes is a sideshow, but this is a chance for us to get together and show we will not be afraid. 90,000 spectators in early summer sun — it's the traditional climax to the football season. arsenal and chelsea meet at wembley in the fa cup final tomorrow. the clubs, and managers, have experienced very different seasons. for arsenal it's a chance to rescue theirs — while chelsea could reinforce their dominance. joe wilson reports. friday at wembley — preparation outside the stadium.

extra armed officers are promised for tomorrow to protect the tradition. two teams, one cup, and not scarf weather. football, after all, is entertainment. alexis sanchez, arsenal's star put them into the final, but he could soon leave. sanchez has scored! and then there's the manager. wembley was yet to be rebuilt when arsene wenger won his first fa cup, 1998. five more cup final victories followed. no manager has won more. but, i wondered, could this final be his last match? i will stay, no matter what happens in football. but at this club? i don't know. there are some people who have admired everything that you have done here, and would think that seeing you lifting the fa cup at wembley would be a perfect way to say goodbye. it would be kind of like a beautiful farewell. does that go through your mind at all? no.

because? what i want is to win the next game. i love to win, and i want to do well for my club. well, chelsea's manager this season has been an image of certainty, prowling the touchlines in his first season of english football. trying just to control his own energy. watch out for antonio conte. here he comes. arsenalfinish fifth in the premier league, chelsea won it. for sure, we are a really good team, but arsenal is the same. we must maintain reputation. for us it is very important to have the desire and the same anger. desire, anger? well, trophies take energy, but there's a time when even another cup may not seem enough. time for a look at the weather. it's been another hot day, hotter

than yesterday. temperatures are about 1 degrees higher, than yesterday. temperatures are about1 degrees higher, particularly in the north—west of wales and the north west of scotland. many places have seen temperatures in the mid—20s or higher. it's no surprise we mid—20s or higher. it's no surprise we have seen stronger than expected sunshine, an abundance of sun xiang, barely a cloud in the sky. through the evening, the are starting to —— abundance of sunshine. that's a start of the breakdown through the evening and overnight. it has been an uncomfortably warm night foremost, there has been sea fog lapping around the shores of eastern scotland, so a different type of day here. a band of showers and thunderstorms make their way eastwards, drying up behind but with more cloud. whatever time in northern ireland and western scotland, and when heat is added to that, there could be torrential downpours around southern scotland, northern england, down northern wales and middle england, perhaps lincolnshire as well. there is more on the warnings on the website. this is bbc news. i'm martine croxall. the headlines at 8:00:

police investigating the suicide attack in manchester say they've got hold of a large part of the terror network behind the bombing. they are very significant, these arrests. we are very happy we have got our hands around some of the key players that we are concerned about. as i say, there is still a little bit more to do. with the security level still at critical, armed police are in force at the start of the bank holiday weekend, with more than 1,000 public events taking place. also this hour, an election row asjeremy corbyn links british military intervention abroad to terrorist atrocities at home. the conservatives call his comments crass and ill timed — but the labour leader insists there must be a new approach to foreign policy. we must be brave enough to admit that the war on terror is not working. we need
