at sunbury—on—thames. tom symonds reports. rapid progress and greater clarity. that is how the police describe this unfolding investigation. they raided this second house in west london, close to heathrow airport, early this morning. they arrested a 21—year—old man. neighbours described him as friendly. he had family that came down from scotland, with young children and so forth. we used to give them lollies. he used to have his friends out there with his prayer mats and so forth, but we didn't think nothing of it. we just thought he was a nice neighbour. armed police! come to the front door now! put your hands in the air! three miles away in sunbury, this was the first police raid, yesterday, on the home of elderly foster parents penny and ronjones. they were led away by heavily armed

police who sealed off the road with large barriers. dave solway saw what happened and knows the couple well. they do their best to guide them and stuff like that. that is why they have been awarded the award they have been given. as i said earlier, it is a shame that this one has bitten. it's nothing to do with them. how do you know? you don't. he said they had been looking after a young refugee who had been troubled and wanted to run away. but he said another young man, originally from iraq, had been living here for several years. the suspect arrested in dover yesterday is iraqi, and they say that this house is directly linked to that arrest. detectives have given no further details, but they are scrutinising the house closely. tents have been set up

to protect possible evidence. however, a 100—metre cordon put in for public safety was removed today. following friday's explosion, the government raised the official threat level to critical, suggesting another attack could be imminent. now it has been reduced again, a signal that the police have a better understanding of the plot and the way in which this makeshift bomb was prepared. the joint terrorist analysis centre, which reveals the threat level that the uk is under, have decided to lower that level from critical to severe. severe still means that an attack is highly likely. i would urge everybody to continue to be vigilant, but not alarmed. terrorism suspects can be held in police custody for longer than usual without charge, up to m days depending on the strength of evidence available. this inquiry has a long way to run. that was tom symonds reporting. he has been explaining more about the lowering of the threat level.

i think what you can say, based on this assessment, which is an assessment of the government makes based on police evidence gathered so far, what the intelligence services are saying, i think what you can say about that is that they don't think there is going to be an imminent plot to attack the public. that doesn't mean that they can necessarily say that they have all of those that might have been responsible for what happened on friday in custody. the reason for that is that police investigations of this sort rely very heavily on getting to grips with the network around those who might carry out attacks on the public. they want to know who their friends and acquaintances are, here and abroad. beyond any plotting that might have gone on. of course, they will be using messaging services that have been used, they will be looking at messages sent on that sort of service. they will be gathering phones. they will be gathering financial data. really, anything you can think of that will help them get an understanding of who the attacker or attackers were, and who they are connected to.

tom symonds, near heathrow. joining me now is michael clarke, senior associate fellow at the royal united services institute. thank you very much for coming in. what conclusions, if any, can we safely draw from what's been happening to the threat level? safely draw from what's been happening to the threat lavenm goes to critical when authorities fear the plot may still be in process. when they think there may be more people involved or other parts that we still haven't seen. when they bring it down back to severe, which is where we sit most of the time from critical back to severe, number four of the five steps, what they're say something we think we have encapsulated the plot, we don't think there is another bomb oi’ we don't think there is another bomb or somebody else out there that is actually planning anything imminently. but of course we go back to the fact we are still very much under threat most of the time. severe is still not something to be complacent. absolutely. the other thing the police worry about and the intelligence services worry about is that as they get closer to getting somebody and the plotf that as they get closer to getting somebody and the plot f there is anything else to that plot, if there

are other people out there, they will know that the police have been knocking on their door quickly and what the police worry about is that getting one plot may actually accelerate another because somebody may know if they're associate of somebody arrested, they know the name of somebody arrested, once that appears in the press, it usually does within about 48 hours, the police worry it will accelerate somebody else planning to do something who thinks better do it now, because the police will be round here in 24 hours or so. that would be someone connected with the arrests already been made? yes somebody connected with the person arrested and that's often the case, what they worry about is that may accelerate another plot. the fact they've gone back to severe indicates from critical, indicates they don't think that's likely in this case. we are back to where we we re this case. we are back to where we were before thursday last week. how impressed should we be with the speed with which authorities have been able to act? it's always quick. these sorts of plots, i always reckon they know who it is within a

couple of hours because it's impossible to make a bomb without leaving your dna on it, impossible. no matter how careful you are. when they've dna, in this case they had a lot of forensics because the bomb didn't work properly, they can compare that with with records they've got. there is an imminence amount of evidence, particularly with a bomb that doesn't really work. there is nobody out there who does these things who is a clean skin, everybody is on the radar somewhere even if they're not looked at carefully, they're on the radar somewhere. it's usually the case they know who it is quickly and then they know who it is quickly and then the question is where are they? in this case they went to pick up this individual and found he got as far as dover, that was probably a bit of as dover, that was probably a bit of a shock but he was apprehended. for your dna to be use you have to be on a database somewhere. a lot of people are. yes, that will be a rich seam to look at when we know more about the person, people arrested. yes. how many successes are there

compared with failures when it comes to investigating these things? well, if you look back at say back to about the year 2,000, depending on how you count them, more than 120 attem pts how you count them, more than 120 atte m pts to how you count them, more than 120 attempts to create a terrorist attack in britain. some would scale it as 150, i reckon it's about 120, maybe 125, of which this year there have been five, before that there we re have been five, before that there were three. so, only eight terrorist attacks have ever worked out of 120-odd attacks have ever worked out of 120—odd that have been tried. so the average is very good. until this year it was excellent. until this year it was excellent. until this year it was three. we are living through a bit of a pike in the incidents. but the authorities are very effective and they're —— a bit ofa very effective and they're —— a bit of a spike. they've have to be effective and lucky as we live through this spike of terrorist activity. we saw this between about 2003, 2008 and then is subsided. we are now back what looks like to a two or three year spike, maybe

longer, of terrorist attempts to do something in the united kingdom. how much of that spike is down to the fa ct of much of that spike is down to the fact of the nature, tactics being used have changed? always changing, the terrorists know, they've learned that you don't have to be sophisticated to commit an act of terror. 0ne sophisticated to commit an act of terror. one of the things they may ta ke terror. one of the things they may take away from parsons green, even a failed bomb creates panic and that's the worrying aspect. generally speaking the public behave well and very brave, but on a tube train at the end of a summer with four previous attacks, there is a degree of panic that wouldn't have been the case if this was march earlier this year. if this was the first attack this year people would have reacted differently. after london bridge causes panic, that's a victory for the terrorists. lovely to see you, thank you very much for coming in. we will find out how this story is covered in tomorrow's papers. borisjohnson has been accused

of misusing official figures after repeating the claim that the uk would save £350 million a week by leaving the european union. the head of the uk statistics authority says he is disappointed by the claim. it came us two cabinet ministers accuse the foreign secretary of back—seat driving by setting out his personal vision of britain. a future after brexit in a newspaper article. two senior cabinet ministers have accused the foreign secretary, borisjohnson, of "backseat driving" by setting out his vision for what he called a glorious future outside the eu. 0ur political correspondent chris mason reports. he was at the heart of a campaign that divided the closest of colleagues. borisjohnson made the case for brexit then... is it not time we took back control? and he has restated it now and resurrected an old row by repeating this. it is perfectly true and verifiable that there is slightly more than £350 million a week that we do not control. the head of the uk stats authority said today this is a clear misuse of official statistics, something that has angered boris johnson.

but some cabinet colleagues aren't thrilled with the foreign secretary either. i don't want him managing the brexit process, what we've got is theresa may managing the process. she's driving the car, to continue the allegory, and i'll make sure, as far as i'm concerned, and the rest of the cabinet are concerned, we help her do that. so this is back—seat driving? yes, you could call it back—seat driving, absolutely. borisjohnson‘s article argued for a bold and positive brexit, leading to claims of cabinet splits and attempts to undermine the prime minister. but despite the headlines, there is no suggestion he will lose hisjob — although political opponents say he should be sacked. it's a terrible situation. it puts theresa may in an impossible position. ijust don't understand why she hasn't fired him. it's like a school that is completely out of control and the headteacher is sitting in her office paralysed and impotent. publicly, the government says it is united about getting the best brexit deal and boris johnson's spokesman says he is fully behind the prime minister,

who is leading the negotiations. privately, there is frustration and some anger at the nature and timing of this intervention, coming less than a week before the prime minister is due to make a major speech on brexit of her own in florence on friday. in an interview with american television, recorded last week and broadcast today, she described her vision for life outside the eu. some people look at brexit and think it was about the uk turning inward. it wasn't. it's about us actually looking out around the rest of the world, but ensuring we can control our own laws, our money and our borders. now it is over to the prime minister to assert her authority over brexit, settle internal disputes and persuade her party she can deliver. a woman and two children remain critically ill in hospital, after a collision on the m5 in gloucestershire which left four people dead. a lorry crashed through the central

reservation yesterday, hitting oncoming vehicles. 0ur correspondent tomos morgan is atjunction 15 of the m5, where the northbound carriageway is still closed. more than 24 hours on and this northbound section between junctions 14 and 16 remains closed as the emergency services continue their investigation, trying to decipher exactly what happened in this horrific incident. a tragedy that led to the deaths of four individuals and left three in a life—threatening condition. it was described as one eyewitness as an utterly horrific incident. a lorry travelling on the m5, just north of bristol, colliding with two cars with devastating consequences. in the moments after the impact, several motorists rushed to help those injured. four were killed, three others critically injured. a woman was taken to southmead hospital and two children were taken to the bristol children's hospital for treatment.

all three are in a life—threatening condition. it's understood the 18—tonne lorry travelling southbound on the m5 crashed through the central reservation before colliding with two vehicles on the other side of the motorway. due to the high—speed, high impact nature of the accident, the clean—up operation has been taking longer expected. forensic teams have been combing the area throughout the night and most of the day, searching for any clues that will help determine how this tragedy unfolded. a number of lines of inquiry we are looking at. one of those is the vehicle itself, are there any defects on the vehicle that caused it to lose control? that is a significant line of inquiry for us at the moment. and what is the latest with the lorry driver? he was treated in hospital. fortunately he was not seriously injured. he is being interviewed under caution by officers and will obviously be spoken to again as part of our investigation. as emergency services continue their work, they have commended the public that courageously went to the aid of those involved.

the southbound section here between junction 14 and 16 has remained open, but the northbound section has remained closed as the emergency services continue their investigation. when this accident happened yesterday afternoon at 2. 30pm, the public, the queue behind the accident rushed to help those that were involved in this incident. the emergency services have commended those that rushed to help those that have been injured. a tragedy that has left four people dead and three in a critical condition, two of which are children. 0ur headlines: the terror threat level has been lowered to severe from critical where it was placed after friday's bomb attack on a london tube. new footage shows the moment police raided the home of two elderly

foster carers, linked to the teenager suspect. the home secretary has accused borisjohnson of being a back seat driver following his newspaper piece setting out his views on brexit. as bangladesh struggles to cope with a mass influx of refugees from myanmar, aid workers are warning more than 1000 children have arrived on their own. they are fleeing the military offensive against rohingya muslims. 0ur correspondent jonathan head reports from the bangladesh/myanmar border. 0n the muddy shore of bangladesh's southernmost point, the stream of muslims seeking safety never stops. this is one of the places where the boats bring them in. 0n the other side of the naf river, still the fires burn. it is astonishing that more than three weeks after the violence broke out in rakhine state, we're still seeing these incredible numbers of people coming across the naf river looking for shelter here in bangladesh.

with so much of the rohingya population already in this country, the chances are the military operation inside myanamar is reaching its natural end. as far as the burmese military is concerned, these people are a historical problem that has now been fixed. mushtaq and his family have just arrived. his home was burned down three weeks ago, he said. he'd sought shelter in four other villages inside myanamar, before being forced to flee to bangladesh. but he has no idea where they will live. the camps that have sprung up to house previous waves of rohingyas are already horribly overcrowded. hafiz manjur has come here to try to find a home for himself and his pregnant wife. he arrived from myanmar a week ago, after a harrowing journey. he filmed parts of it. he's tried three other camps, but he's having no luck.

gosh, there's a lot of people there. all on the move. we've been living in other people's houses, he told me. we had to leave my mother in myanamar. we need to find somewhere we can house her as well, but we don't have much money. bangladesh doesn't want these people settling here. instead, it's planning to build a huge camp for all 400,000 new arrivals, and to confine them there. it's a drastic step for a country that feels its hospitality has already been stretched too far. jonathan head, bbc news, cox's bazar, bangladesh. police are searching for a mother after a baby was discovered wrapped

ina after a baby was discovered wrapped in a blanket in a park in plaistow in east london this morning. 0fficers in east london this morning. officers say they fear for the mother's health and are urging her to come forward. the baby is being cared for in hospital and has been called harry by staff. the liberal democrats leader sir vince cable has said it's perfectly plausible he could be the next prime minister. party members meet for their conference in bournemouth. the lib dems are calling for what they call an exit from brexit. the london fire brigade is still on the scene after fears of a suspected chemical incident. residents reported being able to smell an unknown substance, some felt nausea and some were sick. nine we re felt nausea and some were sick. nine were treated here by the london ambulance service. two were taken to hospital. the london fire brigade says it swept the area, there were no elevated readings of chemicals on

its equipment so this is now handed over to the gas board. i spoke to one of the residence who has been evacuated from one of the homes behind me earlier. i have been fine. i hope my neighbours are feeling all right. i wasn't actually sure earlier on but i realise now a couple have gone to hospital. they've a small child. they wanted to make sure everything was all right with the child. as long as everyone's all right and it gets dealt with, then, you know. police have said it's not believed to be a crime—related incident. we don't know what the substance was which led to people feeling unwell. it is sounding here like it may have been a gas leak. there is also no indication yet of when people will be able to return to their homes. the united states' secretary of state, rex tillerson,

has said president trump is open to keeping the country in the paris accord on climate change. in a television interview, mr tillerson said the president would work with partners if it could construct fair and balanced terms for americans. he said emissions reduction targets in the accord were out of balance for the two largest economies, the us and china. i think if you recall the president also said, look, we are willing to work with partners in the paris climate accord f we can construct a set of terms that we believe is fair and balanced for the american people and balanced for the american people and recognises our economy, our economic interest, relative to others, in particular, the second largest economy in the world, china. if you look at those targets in terms of the paris climate accord, they were really out of balance for they were really out of balance for the two largest economies. so i think the plan is for the director to consider other ways in which we can work with partners in the paris climate accord. we want to be productive, we want to be helpful, the us has a tremendous track record on reducing our own greenhouse gas emissions. there is a chance that if things get worked out, both on the

volu nta ry things get worked out, both on the voluntary side from the us, the volu nta ry voluntary side from the us, the voluntary restrictions for the us, it could change, also with china there is a chance the us could stay in the accord? under the right conditions the president said he is open to finding those conditions where we can remain engaged with others on what we all agree is still a challenging issue. schmoozing before the big night. with the television industry and drying large audiences on a range of platforms, the emmys will be more competitive than ever. the crown, the netflix series about the early life of queen elizabeth ii, is among the favourites. claire foy is tipped for best actress. the american public have always had a fascination about our monarchy. i think, as a british person, you kind of grew up just going, oh, well, they've always been around,

and that's it. but i think the american people have a distance from it, and are able to view them in a different way, and i think that's probably why they've taken the show to their hearts. what are your drives? to meet my maker. westworld, a futuristic thriller based on the michael crichton movie of the same name, has 22 nominations, more than any other drama. it makes me so proud. i knew that, from reading the three pages on the first script, that it was going to be very special. now it's getting the attention and the notoriety, and people are actually connecting to the story. thandie newton and sir anthony hopkins are nominated for their roles in westworld. television has never been more popular, from prime—time dramas like westworld to satirical comedies and binge—watching on the streaming services. no wonder the stars are celebrating. i, donald trump. i, the best—ever donald trump. america's best—known satirical comedy, saturday night live, leads the list of nominees, with alec baldwin nominated for his portrayal of donald trump. political satire is stronger than ever. peter bowes, bbc news, los angeles.

here to discuss the runners and riders is entertainmentjournalist helen 0 hara editor at large at empire magazine. : how important are the emmys? they are tv oscars, that's the simple answer. they're a huge dealfor shows, that's the simple answer. they're a huge deal for shows, especially the ones that are maybe critically acclaimed but haven't so many viewers. an emmy can keep you on the airan extra yearortwo, viewers. an emmy can keep you on the air an extra year or two, it's a huge issue for people. who decides who wins? it's the sort of equivalent of an emmy academy basically. the tv networks and people like netflix have been putting in nominees all year, i think it was 180 people up for best actress, it's a huge deal. if you

wa nt to actress, it's a huge deal. if you want tojudge actress, it's a huge deal. if you want to judge that you have to like watching telly. a lot, it means programmes talked about and written about and watched by most people are a lwa ys about and watched by most people are always in with an advantage. which are the programmes we are likely, are the programmes we are likely, are they even programmes, i am not sure, shows, which ones should we look out for? i think, obviously westworld was the most nominated. i don't know it's necessarily the frontrunner. stranger things has a good chance. the handmaid's tale i expect to do well. big little lies which is is in a limited series, it rolls out differently. but the number of categories is dazzling. they've had to have a separate awards show already to deal with some of them. there is too many for one night. it's a big deal. some people have already won, melissa mccarthy we saw a moment ago has already won for this year. for sean spicer? yes. richly deserved. what about british names? we could be

successful. they could be. clare foy was magnificent in the queen. i don't know she can unseat elizabeth moss in the handmaid's tale that would be my choice. she may have to wait another year. yet people say tv is dying out. clearly it's not. people are watching in different ways. you have a choice really often how to watch. you do. you can take it week by week which benefits some mystery series like big little lies, i think it benefitted the handmaid's tale which is too much to watch at once. bingeking is a pleasure and you can get lost in the world. it's a brilliant era for tv. i think we are seeing some of the best shows that have been on. it's because of the technology of how we are able to watch. it wasn't so long ago that if you were an actor and wanted to make

a name for yourself you needed to aim forfilms, hollywood. a name for yourself you needed to aim for films, hollywood. now you have a—listers absolutely happily taking a series. rightly, it gives them more time to develop a character and play with the same character. it is great. we are seeing an influx of talent and money, influx of different providers of all this tv that are willing to invest in new and risky things. it's great. where does this leave cinema and actually going out to the cinema, buying popcorn and sitting there when you can watch premiers on other platforms at home?|j there when you can watch premiers on other platforms at home? i am biased because i am a film journalist primarily. there is something in the collective viewing at the cinema where you are sitting there together thatis where you are sitting there together that is never going to entirely go away. certainly this year hollywood has had a tough year. there is soul—searching going on about where they put money, how they invest money and what they need to future—proof themselves against the incredible challenge of tv. it's not

televised tonight, you have to wait until the morning to see it. thank you. time for the weather. good evening. it's been another day of sunshine and showers. some showers have been thundery with hail mixed in. most of the showers across central and eastern areas we have seen ease away central and eastern areas we have seen ease away through the night. mostly dry and clear with fairly light winds. in the countryside we could see temperatures falling close to freezing in spots across northern and western parts of the country in particular. monday morning, after that fresh start, with mist and fog around it should clear away. sunny spells and scattered showers again during the afternoon. particularly for central and eastern parts of the country. it will be cooler but further west, more likely to stay dry. monday evening we continue to see showers moving south. clearing the south coast mainly by early hours of tuesday. temperatures again fairly cool, particularly in the rural spots first thing tuesday. things will start to turn milder

tuesday, fewer showers, more sunshine and highs by the afternoon of around 15—18. bye. hello. this is bbc news. the headlines: the terror threat level has been lowered to severe from critical — where it was placed after friday's bomb attack on a london tube. the home secretary has accused boris johnson of being a backseat driver, following his newspaper piece setting out his views on brexit. a woman and two children remain critically ill in hospital after a collision on the m5 in gloucestershire which left four people dead. the un secretary general says myanmar‘s leader, aung san suu kyi, has a last chance to end the military offensive that's forced 400,000 rohungya muslims to flee to neighbouring bangladesh.
