this is bbc news. the headlines. the labour mp chuka umunna has urged leaderjeremy corbyn to "call off the dogs". in a speech, the former frontbencher said centre—left mps like himself were being driven out of the labour party. my message to our leadership is clear. it is within your power to stop this, so call off the dogs and get on with what my constituency, one of the most diverse communities in the country, demands we do. people being harassed by cold callers will be given powers to stop them in new measures introduced by the government today. russian war planes have launched fresh strikes on the syrian province of idlib as protesters call for international help to stop the offensive. turkey and others have warned of a potential humanitarian disaster. and an attempt to clear plastic waste from the pacific ocean gets underway today. for the first time ever, a 600 metre long boom

will be towed through the middle of the pacific ocean to collect plastic waste. and at ii.30pm — you can watch dateline for the latest analysis on brexit and other top stories from around the world. the labour mp, chuka umunna, has appealed to his party leader, jeremy corbyn, to — in his words — "call off the dogs", and stop centre—left mps being driven out of the party. it comes as a third labour mp, chris leslie, has lost a vote of no confidence among some members of his constituency party. our political correspondent, pete saull, gave us his assessment of mr umunna's comments. pretty striking language today from

chuka umunna, he certainly not mincing his words and he has criticised jeremy in the past but the essential point today it is a growing fear among him and other labour moderates that there is an organised campaign out to get them at the moment. this was the key point in the speech, he said there is only one person who can sort that out and that is jeremy is only one person who can sort that out and that isjeremy corbyn... having only been re—elected by the constituents last year, often with big majorities, already centre—left mps are being systematically targeted with motions against them in their local parties, motions brought against them for standing up for the centre—left values. for example, demanding we have a zero tolerance of racism in the labour party. more motions are expected by colleagues in the weeks and months to come. my message to the leadership is clear. it is within

your power to stop this. so call of the dogs and get on with what my constituency, one of the most diverse communities in the country, demands we do. without equivocation, fight this tory brexit. that is where all of our efforts should be. there has been a lot of talk about the forthcoming labour party conference, whetherjeremy corbyn will change the rules on how mps are voting but we are already seeing deselection talk —— votes. voting but we are already seeing deselection talk -- votes. not so much deselection bid votes of no confidence, these are non—binding votes but they could potentially... they are kind of almost thinly veiled threats that they have the numbers to potentially deselect if it were to come to that. this week, john ryan and gavin sugar, two they we re john ryan and gavin sugar, two they were mps critical ofjeremy corbyn, getting no—confidence vote against them by their local parties and you mentioned in the introduction of former chancellor michael shadow

chancellor, chris leslie, who lost a vote of no—confidence in nottingham east this week as well. but a lot of focus today about john east this week as well. but a lot of focus today aboutjohn ryan, because the day after that meeting, a video appeared on twitter posted by iranian state television which a p pa re ntly iranian state television which apparently was at that meeting and she says she is horrified by the fa ct she says she is horrified by the fact that those apparently american -- iranian fact that those apparently american —— iranian state tvjournalists were there and chuka umunna brought this up there and chuka umunna brought this up after the speech this morning.|j think, what on earth are we doing when we have a situation, if you look at the experience of my colleague, john ryan, in enfield, where you have a labour party meeting is being streamed and broadcast by the iranian state broadcaster... i mean, in 2018, really? when what every single party, local party and the national party, local party and the national party, should be fixated on is how

we stop this terrible brexit damaging every single member of the community. we have to get our priorities straight. it is important to say thatjeremy corbyn has boosted labour party membership to huge levels. what are we expecting to see in terms of pressure on some mps in their local seats in the coming weeks and the conference? that is right under labour membership stands at around half a million people and jeremy corbyn supporters point out that it is quite right in there a few that their elected representatives reflect the views of this now much larger membership and they say these votes of no confidence are effectively just democracy votes of no confidence are effectivelyjust democracy in action, they say. but it is really about, with these no—confidence votes, then flexing their muscles. they are saying to their labour mps, if you step out of line and continue to criticise the leader as he have done, then we do have the numbers to potentially deselect you if it comes

to that. chuka umunna saying, will jeremy corbyn call for a second referendum on brexit? any chance at all of that? we have to wait and see other are several trade unions that have got behind this campaign and the labour position is they would rather have a general election than a second referendum, they wanted that to be kept on the table, if they don't believe the deal with the government comes back with is suitable for them. you can expect a ratcheting up of pressure onjeremy corbyn on that issue because interestingly, it is notjust moderates like chuka umunna who back a second referendum, it is the overwhelming majority of the labour membership as well so that will be a key theme at the party conference, too. new powers come into force today designed to stop nuisance calls from personal injury and claim management firms. you'll now need to opt in to allow companies to contact you. businesses that don't comply could face a fine of half a million pounds. manuela saragosa has more. for many of us, cold calls are a daily torment. hello?

the financial conduct authority says some 2.7 billion nuisance calls texts and e—mails were made over the past year. that works out to be about 50 calls, texts and e—mails sent to every single adult in the country. many are made by companies offering to settle personal injury claims, or to claim back ppi — payment protection insurance. but, from now on, these companies will have to check first that the recipient has explicitly agreed to receive those calls and messages. companies that don't could face a fine of up to £500,000, and people are encouraged to report them to the ico — the information commissioner's office. some companies will see the new change in law and i think they will desist from the activity. when they don't, i'm afraid people are going to have to complain. the ico does need the information from people about these calls, and she will then tackle, use her powers and, slowly but surely, we will get on top of it and they will completely cease. campaigners say the new rules

do not go far enough. they will not, for example, stop calls from fraudsters and note, too, that firms based overseas are not covered. the issue of consent, they argue, is a red herring and they would prefer to see the authorities rule that unsolicited direct marketing calls are not a legitimate way of doing business. manuela saragosa, bbc news. russian warplanes have lauched more airstrikes on rebel positions in syria's idlib province as government forces continue their military build—up. the united nations is warning of a major new humanitarian crisis if syria and its russian allies launch an all—out military offensive. idlib is the last major rebel stronghold in northern syria. thousands of civilians are trapped in the area and turkey fears a new refugee crisis if they are forced to flee across the border. the head of the us military says he's spoken to the white house about what happens if syrian forces use chemical weapons in an assault on idlib.

0ur middle east correspondent, yollande knell, reports. with the fate of idlib hanging in the balance, its residents are taking to the streets, desperately calling for international intervention to prevent a deadly government offensive in this rebel—held area. this man demands that the un special envoy on syria and his colleagues stop any bloodshed. they must protect people from air strikes. civilians are being targeted, he says. the un security council did meet yesterday to discuss idlib. there were fresh warnings that any battle for this province would be horrific and bloody. it's feared that tens of thousands of syrians could be caught up in a humanitarian catastrophe. but when russia and the assad regime say they want to counter terrorism, they actually mean they want to bomb schools, hospitals and homes. they want to punish the civilians who had the courage to rise up against assad.

but earlier at talks in tehran, russia and iran, key allies of the syrian government, ignored turkish calls for a truce, insisting that islamist militant groups must be dealt with. and as if to make the point, russian warplanes and syrian government forces have been continuing to bomb rebel positions in idlib. now many syrians here are fleeing. there's a growing sense that this seven—year—old war that killed hundreds of thousands is reaching its final stages. yolande knell, bbc news, beirut. it's emerged that a russian exile who was murdered in britain last march believed that two men from moscow had tried to poison him five years earlier. nikolai glushkov, a former deputy director of the russian airline aeroflot, was found apparently strangled at his home in south—west london. his death came a week after former spy sergei skripal and his daughter, yulia, were poisoned in salisbury.

the police have now reopened their investigation into the incident in 2013, in which mr glushkov was apprently taken ill after drinking champagne with two russian men. a former trump campaign adviser has been jailed for 14 days, for lying to fbi agents investigating alleged collusion with russia. george papadopoulos — who admitted the offence — was also ordered to do 200 hours of community service and pay a fine of $9,500. papadopoulos is the first former member of the trump election team to plead guilty to offences during the 2016 presidential campaign. john mcmanus reports. this is the former adviser to president donald trump who is now swapping the white house for the jailhouse. george papadopoulos‘ crime? he admitted lying to fbi investigators who are looking into allegations that russia interfered in the us election. mr pa padopoulos‘ role began in early 2016, when the trump presidential campaign signed him up as a foreign

policy adviser. when mr papadopoulos was questioned by officers investigating alleged collusion between russia and the trump campaign, he said he had met individuals with ties to russia before he worked for the president. in fact, he had met them after that point and it's this lie, which he pleaded guilty to, which has led to his sentence 01:14 days injail. 0utside court, mr papadopoulos‘ lawyer said his client had acted stupidly by following the president's line on the russia investigation. he was tweeting seven days before george was interviewed, and he's the president of the united states, that based on all of his information, i would assume, that this was a witch—hunt and that it was fake news that russia had meddled in the election. donald trump has always denied ever seeking help from the kremlin to win the election, and his reaction to the sentencing was typically bluff, complaining about the cost.

but this investigation is worrying the white house. no evidence of russian collision has so far been revealed, but several people close to the president have been found guilty of various other crimes. john mcmanus, bbc news. one person has been arrested in barnsley after a man was stabbed in the town centre. police were called to the area this morning and a number of shops remain closed. the victim suffered minor injuries. a massive operation to scoop plastic waste from the middle of the pacific ocean is being launched today. a 600—metre long device will be towed out from california, as jenny kumah reports. sights like this have shocked people all over the world. the damage to wildlife has inspired a bold project with an ambitious goal — to rid the ocean of plastic. and this is the structure that will help to do it. it's been built in san francisco and is launching from there today.

it will travel to an area in the eastern pacific known as the great garbage patch, where currents trap plastic. if we don't do it now, all this plastic will start breaking down into smaller and smaller pieces, and the smaller the pieces are, the more harmful and harder to extract from the marine environment. so we feel there is a sense of urgency. so how will it work? a giant tube, 600 metres long, will float on the surface in the shape of a horseshoe. over time, the plastic should gather in a small area and then can be taken out. underwater, a barrier will hang three metres down and trap plastic below the surface. it is meant to allow fish to swim underneath it. but some experts worry that the system can harm wildlife. our major concern is for those passive floaters, rather than fish, mammals, plankton, jelly fish, for example. they simply cannot get out of the way of this, they are going to be crammed

into this and not be able to escape. the plan is to start with one collection device and eventually deploy 60. the people behind the project estimate a full roll—out will clean up half of the great pacific garbage patch in five years. jenny kumah, bbc news. the headlines... labour mp chuka umunna has accused jeremy corbyn of driving centre—left mps like himself out of the party. companies can no longer make cold calls unless a claimant has opted in to receive them. claims management companies that break the rules will face large fines. russian war planes have launched fresh strikes on rebel—held positions in the syrian province of idlib as protesters call for international help to stop the offensive. and in sport... england are 67—1 as they look to

overhaul the unlikely lead from england on the final test. india trailing by 265 runs. will grigg scores a consolation goal at windsor park as northern ireland lose their opening nations league fixture 2—1 to bosnia herzegovinia. england kick off their nations league campaign against spain this evening at wembley. the last time they played it was a 2—all draw but manager gareth southgate believes his side are better prepared this time. and history beckons for serena williams as she prepares for tonight's us open final hoping to equal margaret court's grand slam record. more sport at 5:30pm... tributes have been paid to the us rapper mac miller, who's died after an apparent drug overdose. the 26—year—old, who's real name was malcolm mccormick, was found at his home near los angeles. he rose to fame after topping the us charts with his debut album in 2011. earlier this year, the musician went through a well—publicised break—up with his long—term girlfriend, the singer ariana grande. a couple and a child have had

a miraculous escape after a tube train went over the top of them at baker street station in london last night. police say the woman was pushing a buggy along a platform before falling onto the tracks after being distracted by looking at the arrivals board. the fatherjumped down to help and as they saw a tube approach. the three of them moved into a pit beneath the track. thankfully, the tube passed safely over the top of them. none of them was seriously hurt but they were taken to hospital for checks. in a statement, transport for london said they were relieved that the family were able to escape unharmed. they underlined the need for customers to remain behind the yellow line when waiting for trains or walking along the platform. sweden's prime minister has urged voters to reject extremism and fascism on the final day of general election campaigning. stefan lofven said that supporting the far—right sweden democrats party — who are forecast to win around 20%

of the vote — was "dangerous" and "counterproductive". neither his centre—left social democrats nor the main centre—right party is likely to win a majority. earlier i spoke to james savage, the stockholm—based founder of online news publisher the local. i started by asking him for his election prediction. the polls are showing very different kinds of results. we are seeing with some that the estimate for sweden democrat is anything from 17% to 25%. that could mean they are the largest third largest party. whatever happens, the way that the system in sweden will mean that there will still be a coalition government, but almost certainly will not include the sweden democrats, because the moderate party on the centre—right and its allies, and the social democrat party, the ruling party right now,

have said that they won't do deals with it, which means there will be no sweden democrat ministers in any kind of government. but we have seen some interesting developments over the last two years. we have seen the big parties have shrunk, and the sweden democrats, and other parties, including the former communist left party and the liberal centre party, we have seen them grow at the expense of the major parties. obviously this is following a trend we have seen across europe and other parts of the world where migration is a key dividing factor. are the other parties going to be forced to take on some of that grand? they already have. in 2015, as many will be aware... sweden took in a lot of refugees and it became clear they could not cope with some of the numbers arriving. it introduced much more

strict migration policies. most parties, all the larger parties, supported those much stricter policies. that has already been baked in, but there was a shock to the system in 2015, and i think a lot of voters felt unsettled by the number of people arriving, and a perception perhaps that the big parties didn't really have control of the situation. that helped the sweden democrats grow from where they were at the last election, around 12%, to where they are now, 17—25%. it has help them and it has forced other parties to re—evaluate their position. is enough being done in terms of supporting areas which have seen migration? is there enough in terms of welfare and organisation? there are problems in certain areas that are immigrant dominated. some of the suburbs of stockholm, gothenburg and malmo. there are problems with segregation,

and with poverty and unemployment. there are lots of activities going on in those areas, both at local government level and that national government level to try to help integration and help people to get into the job market, and to deal with some of the other social issues which come from immigration. clearly, i think all parties accept that more needs to be done. the approaches differ from the sweden democrats, who have made approaches to clamp down on immigration even further, to the social democrats, who are much more focused on demanding things for the immigrants who have arrived. james savage in stockholm. almost 120 council estates in london

are facing redevelopment, which campaigners fear means the loss of thousands of council homes. freedom of information requests submitted to all london councils reveal that dramatic changes to the capitals social housing stock are underway, which will affect the lives of tens of thousands of residents. gareth furby reports. across london, thousands of council properties are being demolished as estates are being refurbished and redeveloped. but is this good news? some campaigners and experts say it may not be. we have a situation of what we might call hyper—gentrification. council estates have very much become a target for making profit. the claim is that social housing across london is being lost because, when the improved estates are completed, there tend to be fewer homes for council tenants. the green party's sian berry claims she has new figures which prove that regeneration is having a negative impact. i looked at what is called the london development database. we have a net loss of over 4000 homes, schemes that have been

completed over the past 15 years. and when you look forwards, schemes that have planning permission now, it gets even worse. there are 7600 homes to be lost over the next ten years. so the whole process is accelerating. city hall says council homes lost in estate demolitions have been replaced through other housing schemes and, overall, numbers are up. but the pace of change is significant. a total of 118 council estates are undergoing or earmarked for regeneration in the next five years. affecting 31,000 residents. more than 80 estates will be fully or partially demolished. author anna minton says the track record of some regeneration work, such as at the heygate estate in southwark, hasn't been good. the heygate estate was demolished a couple of years ago. it's been replaced by elephant park, a luxury apartment development.

almost 3000 homes — of those, only 82 are social housing. campaignerjerry flynn, who lived here before redevelopment, says it is all about the money. the property developers are the winners of regeneration. all the regenerations are public—private partnerships. the profitability of the scheme is the first benchmark of deciding whether the scheme is going to go forward. southwark council says most of the original tenants have been rehoused in the borough and lessons have been learned. the mayor, sadiq khan, says he has introduced controls to ensure redeveloped council estates to keep their social housing. but campaigners fear social housing is under threat and say they will keep up the fight. gareth furby, bbc london news. what's it like to be a rookie prison officer at a time of high levels of violence, drug—taking and self—harm ? two years ago a scheme to get some of britain's brightest university graduates working

in jails was unveiled. so would the new recruits go the distance? last year, our home affairs correspondent, danny shaw, met one of the graduates as she started work at coldingley prison in surrey. now he's returned to find out how she's getting on. i'lljust give you a quick rubdown, mr brown. she's one of the newest prison officers at hmp coldingley, but has the confidence of someone far more experienced. sophie is one of the standout recruits on a programme designed to attract the brightest graduates into prisons. we first met her 12 months ago, when she started work. i've finished my degree. 0k. the new officers were visited by the then justice secretary david lidington. a year on, how has it been? it's been challenging, but it's been rewarding, as well. the best thing is all the interactions that i have with the guys. we make progress all the time. the small wins are the best things — like, getting someone that has been refusing to go to work that is actually finally engaging and going to work.

that's the best thing ever. have there been moments when you've doubted whether this was the job for you? when incidents happen and i've been faced with, like, an act of self—harm or someone being under the influence, and that's when i'm like, "am i right for this job?" sophie is one of eight graduate prison officers here at coldingley. they are among more than 50 who started the scheme last year. and now it is being expanded and sophie is helping to train the next set of recruits. if they are not in there, you open the flap. these new recruits graduated in subjects including anthropology and social policy. now, they are earning up to £30,000 a year and doing a masters in their spare time. show that you are listening, that you understand. and this is how the graduates learn about techniques they need to do the job. hello, it's 0 from alpha 1. we have an unconscious officer, officer ralph. it's a training exercise in a classroom at the university of suffolk. i can see there's a rope going through the window,

we have missing keys. in this scenario, a prisoner has escaped after assaulting a member of staff. we have an e—list prisoner escaping out of education 1 with a set of officer's keys. the skills you get from being a prison officer, if you can de—escalate a landing full of prisoners, if you can convince someone who's offended their whole life that they want to change and turn their life around, essentially, the skills that they're going learn with us will set them up for leadership and whatever they go on to do. at the time, we had real problems with recruitment. attracting people to the service, there was a lot of negative press. rising levels of prison violence and concerns over pay have made it hard for governors to find and retain staff. 2000 front—line officers left the service last year, hundreds of them new recruits. to get some of these bright young people into it was like a shot in the arm. but sophie isn't at coldingley for long. next year, she'll leave for good, using her experience in another part of the criminaljustice system. danny shaw, bbc news, at coldingley prison. now it's time for a look at the weather with stav.

it has been atrocious afternoon across parts of northern england and the north midlands and parts of north wales as well but outbreaks of heavy rain. this evening, the rain will ease down time before more rain arrives towards the end of the night. you can see that away gradually, turning drier but cloudy for england, wales and northern ireland after a lovely day across northern scotland and the skies remain clear here. could be cool here, but further south, as the rain arrives across western areas, it should be milder. we start sunday on a damp note, outbreaks of rain pushing northwards and eastwards and into the afternoon a better picture, drier, brighter with sunny spells and showers across western areas and most and showers across western areas and m ost a cross and showers across western areas and most across western scotland, where it will turn windy. temperatures across england and wales, 21—23.

starting next week, northern areas remain unsettled and on the cool side and staying drier and warmer in the side. hello, this is bbc news. the headlines: labour mp chuka umunna has said jeremy corbyn supporters are driving centre—left mps out of the party, as he urged the leader to "call off the dogs". new powers designed to end nuisance calls from personal injury and claim management firms come into force today. companies will have to make sure people have opted in to receive their calls. russian war planes have launched fresh strikes on the syrian province of idlib — turkey and the united nations have warned of a humanitarian catastrophe in the event of an all—out offensive. and a californian coast clean—up begins today, as plastic in the pacific ocean is collected using a 600 metre long boom. now on bbc news, it's time for dateline london.

hello, and a very warm welcome to dateline london with me, tim wilcox. this week we discuss the perilous situation for millions of civilians in idlib as government forces prepare to clear the last remaining rebel stronghold in syria's north western province. there are warnings of a blood bath after a summit between the presidents of russia, turkey and iran — where it was hoped a deal would be struck, ended in failure. and with the long, hot parliamentary summer recess finally over — where are we in britain's brexit saga?
