takes a look at whether it is time for regulation of social media. good morning. welcome to bbc news. a french police officer who helped bring a terror attack to an end by swapping himself for a hostage in a supermarket siege, has died in hospital. three other people were killed and several injured in separate attacks by a gunman who claimed to be acting on behalf the islamic state group. he was later shot dead by police. lucy williamson reports. france's interior minister called it an act of heroism, but arnaud beltrame's acts also seem to have been key in ending the deadly siege at a supermarket near ca rcassonne.

on entering the building, in exchange for a hostage being held at gunpoint by 26—year—old redouane la kdim, lieutena nt—colonel beltrame secretly kept his mobile phone connected to colleagues outside, allowing them to hear what was going on. the attacker had already killed two of his captives and mr beltrame was shot several times before security forces stormed the building, killing the gunman and ending the siege. three people were killed in a series of attacks by redouane lakdim and more than a dozen injured. he claimed to be acting on behalf of the jihadist group islamic state and said he wanted to secure the release of salah abdeslam, a french detainee linked to the november 2015 paris attacks. lucy williamson, bbc news, carcassonne. our correspondent gavin lee is outside the supermarket in trebes where yesterday's attack took place. a short while ago, police lifted the cordon close

to the supermarket in trebes. this is where the siege took place for several hours yesterday, the super u. you can see a number of trolleys still knocked over. the scene is as it was. police outside as the investigation continues. the news this morning of the death of the police officer who the french president emmanuel macron said saved others' by swapping himself for one of the hostages, this is 45—year—old lieutenant colonel arnaud beltrame. it was said that he passed away in the early hours because of the severity of his injuries. it was said that he showed true courage, true spirit and true bravery. we know that he was amongst the first at the scene at 11 o'clock yesterday morning. there were 50 people in the supermarket behind me. a number of those were still being held hostage. some had escaped through the refrigerated meat area

and through a door at the back. this officer, who had had some brief contact with the attacker, offered to swap himself for a 45—year—old female shopper. he went inside. he left his phone on a desk. it was left open so that police intelligence services, police special forces could listen. 45 minutes later, they heard gunfire. they went in and killed the attacker. but because of the severity of the injuries of the police officer, he was killed. two others were killed inside by the attacker we now know as 25—year—old moroccan national redouane lakdim. he was living in carcassonne with his mother and sisters. he had been on a french terror watch list, but was deemed not to be somebody who had gone down the path of radicalisation, so he was taken off. he was seen as a petty thief. he had been imprisoned in 2016,

so there are more questions over why he was taken off that list. but right now and over the weekend, the forensic work here continues. social media has been flooded with tributes to the french police officer. the announcement that he had died came from the interior minister at about 5:20am this morning. a number of the tributes from people involved in policing in this country. stirling police treated a picture of the gendarme. the former shadow northern ireland secretary, owen smith, has said he will continue to oppose labour's stance on brexit after he was sacked for calling for a second referendum on the terms of the final leave deal. mr smith said he believed jeremy corbyn wanted to adopt a more eurosceptic approach which he believed would damage the country's economy. he told bbc breakfast that mr corbyn was not speaking up for the majority of labour party members

on the issue of brexit. labour members have been speaking out strongly and members across the country have contacted me before and after my sacking to say that this is what they believe in the vast majority of labour members support is taking a much tougher stance against brexit and that is what i thinkjeremy corbyn and the leadership of the labour party need to do. earlier chris mason came into the studio and i asked him why he had sacked owen smith. firstly he wrote an article, he cannot blame this on encountering a pesky reporter like you or me being asked devilish questions and blurting something out that he later regrets, oi’ something out that he later regrets, or something that he has written for private audience that slipped its way the bloodstream of national debate. instead he pulled out his

la ptop debate. instead he pulled out his laptop and he typed out a relatively short piece, albeit with a stinging conclusion in terms of his view versus labour's view. firstly he said that the uk should stay in the single market after brexit and it isn't labour policy. secondly at the end of the negotiating process instead of a vote in parliament which the government are promised an labour endorses, they are pushing for what they see as improvements to that but owen smith serves why not have another referendum, that is also not labour party policy so in that sense, in a very public forum, and thought through peace, he has meandered several miles away from the party line. presumably he is not arguing or pushing for something the labour party is not committed to, he is just saying it is a legitimate pa rt is just saying it is a legitimate part of the debate and he can't understand why he is sacked for it. what owen smith actually said is not remotely surprising to students of

owen smith politics, of which there are many, i am one, i am a nerd and i covered the election campaign in the lady leadership campaign two yea rs the lady leadership campaign two years ago where he covered —— challenged jeremy corbyn. last summer challenged jeremy corbyn. last summer he took a dig around jeremy corbyn‘s top table in the conventional so—called collective responsibility is using from him should party policy whether you or not. how does labour square that with this letter that was in the public domain since diane abbott sent it to her constituents and she says that the government won the vote of moving the brexit bill to the next age but the labour party continue to push for the many are not the nightly shoe argues for the electorate voting on the deal. interesting. it is tricky from the tea m interesting. it is tricky from the team corbin perspective. it is a letter to which several of owen's

supporters have gazed intently in the last few hours. it is only four months old. quite quickly after that she popped up on question time and did a discrete traverse manoeuvre in front of david dimbleby in a large audience on bbc one. there was clearly a discrepancy people are pointing to that. i suppose the argument might be that this is not a public forum as much as the guardian, although it did become that. it is clearly tricky some will point out that diane abbott is a fellow political traveller with jeremy corbyn. owen smith is very much not but equally owen smith will have known and did know that when he wrote this column there was clearly the potential, quite high potential that it would cost him his job. a former classmate of the russian spy poisoned in salisbury has claimed that his friend wanted a full pardon from president putin. vladimir timoshkov told bbc news

that sergei skripal regretted becoming a double agent. mr skripal and his daughter yulia remain critically ill in hospital. well, let's get the latest from salisbury where the attack on mr skripal happened. our correspondent kathryn stanczyszyn is there. the police officer heard the attack has had a letter from a the police officer heard the attack has had a letterfrom a russian ambassador, that is intriguing? yes, the political and diplomatic fallout continues from this. the kremlin has denied ever receiving that letter that was being talked about in that clip there, a letterfrom that was being talked about in that clip there, a letter from screen that was being talked about in that clip there, a letterfrom screen pal allegedly asking for forgiveness and they have denied and they have repeatedly denied having anything to do with the poisoning and the latest denial of it comes in this letter that was sent to ds nick bailey who was taken ill after the poisoning and was discharged from hospital on thursday. it is a letter from the russian ambassador to the uk, basically wishing him a speedy

recovery, but also claiming that they have nothing to do with what he describes as this reckless incident. he says he was relieved to hear it you were released from hospital and reunite with your family and i wish you a full recovery and hope you will be able to return to your normal life as soon as possible. i would like to express my gratitude to you for the bravery in reacting to you for the bravery in reacting to the assault on two russian nationals on the 4th of march in salisbury. please be ensured that russia has with this reckless incident and is ready to cooperate with the british authorities with regard to the investigation post bilaterally and through international organisations. a lot of the russian response has been described as insincere by british authorities with borisjohnson saying last week that all ears hearing your smug sarcasm. this letter is the latest on that. ds nick bailey is not reacting to it specifically as yet but we do know after he was discharged from hospital on thursday he says his life will never be the same. the

signs behind you illustrate the fact that not only does the investigation continue but there remains concerns about insuring people's safety as a result of this nerve agent being released. toxins potentially in the errant peoples clothing and so on, what advice is now being given to people on the ground? it is surprisingly survives still needs to be given. it was surprising to people when the first lot of public advice came out almost two weeks ago now. i am standing in front of the park outside the vaulting is where the bench that the skripals were found was situated and it was removed yesterday in what is one of the largest and most complex counterterror investigations and it was removed and taken for more forensic investigation but we know anyone who was in the vicinity of the restaurant on the 4th of march

until monday closing time, either there or the pub that was just around the corner, we're told a week later that they must wash their clothes and clean any possessions in case of a further risk to help —— health. there was no imminent risk but repeated exposure might cause that risk. they also said any clothes that can't be washed, special items or dry clean items, they should be double bagged and kept somewhere safer now the diebold —— latest line from the council is to co nta ct —— latest line from the council is to contact them because they will comment pick it up and destroy those belongings. some people are asking if that was the case, why was it not said a while ago? thank you for that update. 18 investigators from the uk's information commissioner have been searching the london headquarters of cambridge analytica overnight, after a high courtjudge granted them a warrant.

the firm is at the centre of a data privacy row and is accused of using information from millions of facebook users to help political campaigns, without their consent. ben ando reports. after a week of waiting for a warrant, last night the inspectors called. theirjob — to search the offices of cambridge analytica for evidence that data gathered via a facebook personality test from around 50 million americans in 2014 was not destroyed and whether, if cambridge analytica used the data, it had an impact on the election two years later that put donald trump in the white house. that seemed to be the claim of its since suspended boss when recorded by undercover reporters. some believe it's time to ask what we want from the web. we can act collectively and think carefully and deliberate meaningfully about what matters to us in terms of a digital environment and a digital world and impose appropriate constraints upon what is done with our personal data and where we think the boundaries ought to be. others are already voting with their keyboards. elon musk, the founder of spacex, has revealed that he's the most high profile user yet tojoin the so—called delete facebook movement by culling his

company's profile pages. the inspectors left in the early hours of the morning. what we know about the information commissioner's investigation is that it is looking into how data can be used for political purposes. both facebook and cambridge analytica deny any wrongdoing. ben ando, bbc news. hundreds of thousands of people are expected to take part in marches across america later today, calling for tighter gun controls. the main rally in washington will include survivors of last month's school shooting in florida. people are also expected to demonstrate outside the us embassy in london. our correspondent chris buckler reports. parkland students have travelled hundreds of miles from florida from the school where their classmates and teachers were killed, a shooting that many of them survived. in washington, they've already been lobbying politicians, and today they'll be joined by tens of thousands of others in a march

calling for new tighter gun laws in the us. i'm doing this because i don't want any other student to have to go and attend a friend's funeral instead of their friends birthday party. those who fled the marjory stoneman douglas high school started the campaign that has led to the march for our lives and they have inspired a huge number of others. alongside services and protests, hundreds of sister marches are due to take place today across america and around the world. i can honestly say that prayers do not feel like enough. we must act. we must act to change current laws that allow profound devastation and heartbreak. despite the strength of america's gun lobby, there are some signs that the white house is having to listen. the usjustice department has confirmed that it is pushing ahead

with proposals to ban so—called bump stocks. they are devices capable of enabling a semiautomatic weapon to fire like a fully automatic machine gun. but the students leading this campaign believe that's only a start, and they hope the size of today's march in washington will add to the pressure on president trump. the headlines on bbc news: the french police officer who swapped places with a hostage in an armed siege at a supermarket has died. owen smith says he'll continue to argue against brexit, despite being sacked from the labour front bench over the issue. as we have just been hearing as we havejust been hearing in as we have just been hearing in the united states thousands of people are preparing to take part in the latest rallies calling for tighter gun controls. now, how should hospitals treat homeless people? they are admitted for emergency treatment many more times than the average patient and stay on average twice as long.

but often, they are simply discharged back on to the streets. one charity wants to change that. it started in london and is expanding across the uk. dougal shaw reports. meet gary spall. he slept rough in london for more than a decade. in that time, he had multiple acute health problems. he was in and out of this central london hospital. typically, he was discharged back onto the streets. this is where i used to bed down. it's horrible. in winter, even worse. how did you feel when you made the five—minute walk out of hospital back to this? it's not a good place to recuperate. really depressed. but thanks to the pathway charity, the nhs became a way to save gary. they made contact with him during a stay in hospital and used it as a chance to turn his life around. now he has a home and a beloved pet dog, lola. the charity helps 3,000 homeless people each year,

operating in 11 hospitals across the uk, like this one in east london. it assembles a dedicated team to help the homeless. this includes a gp, a nurse, an occupational therapist and crucially, a care navigator. he is trusted by homeless patients because of his background. sometimes we'll get a patient who says to me "you don't know what it's like to be on the street and be homeless," and i can turn round and say i do understand what that feels like. i've been through the system. i have been homeless. gavin has to first locate homeless people who have been admitted to hospital. this is the charity's chance to stage an intervention to turn lives around. the pathway team addresses underlying health issues, but they also sort out immediate problems like getting fresh clothes, and help to find housing after leaving hospital. the team hosts a weekly meeting where representatives from housing associations, local hostels and the police can share knowledge to sort out individual cases. this might seem like a lot of work in a stretched health system,

but the medical director of the pathway charity says this approach makes sense for hospitals. we can reduce the amount of time people spend in hospital and the need for them to come back to hospital again. so the net result is reducing the stress on the nhs. if not for pathway, i don't think iwould be here now, alive, and everything is going good now. sport now and for a full round up from the bbc sport centre, here's holly. there is formula 1 coming up this weekend end of this afternoon there isa weekend end of this afternoon there is a boat race. plenty of news to come on a boat race. let us start with formula 1. it is back and lewis hamilton is getting better. he starts tomorrow on pole position after producing a lap he says is as close as he can get to perfection. the reigning champion clocked the quickest time

ever seen in qualifying at albert park. the gap to the ferrari cars of sebastien fettle and someone else is more than1.5 sebastien fettle and someone else is more than 1.5 seconds. the rain cleared in time for formula 1 but overin cleared in time for formula 1 but over in auckland the bad weather wiped out virtually the entire third day ‘s play. only 17 bowls world bowls and the hosts increased their lead. there was time for henry nicholls too reaches of secretary of the bowls. it was a successful actor gareth southgate in amsterdam as his england team showed enough to beat the netherlands 1—0. jesse linegard

scored his first international goal to extend the unbeaten run to seven matches for england. the world cup preparations continue on tuesday against italy at wembley. very composed performance. we use the ball really well. we played from the back and it was really good composure and tactical understanding and then as we progressed forward with good pace and energy to the tea m with good pace and energy to the team that men we look to threat. no i°y team that men we look to threat. no joy for scotland fans. costa rica, six places above and world rankings we re six places above and world rankings were comfortable winners at hampden park. 1—0. scotland play hungary on tuesday. i was a bit disappointed. we were never really up on them the way we wanted to be and high on the

back three. make the goalie kick. they still played out a wee bit but i think it was because we were half—hearted. i think it was because we were half-hearted. northern ireland are in action later today and after meeting the world cup in russia michael o'neill is looking to the future starting the good performance against south korea, he hopes. the opposition a very good and it will bea opposition a very good and it will be a big challenge but that is the nation of this, all part of the learning curve for the younger players coming into the and potentially into the team. we have nine games between now and march that are of march 2019 and all of those are valuable in terms of preparation and growth for the next campaign. oxford and cambridge universities go auto or this weekend

in the boat race. oxford have run four out of the five past races and eye catching up with cambridge in the overall standings. it is 82—82 the overall standings. it is 82—82 the light blues but there was a bigger gap in the women's adept at with cambridge leading 112—30 but oxford have an experienced crew and hope to narrow the gap. it is 80 yea rs hope to narrow the gap. it is 80 years since the event was first televised by the bbc. cambridge are pretty motivated to win this year. don't want to take anything for granted and certainly we have lost enough guys from last year and have few enough return is that it is essentially a new bunch of guys. i think we have three returning blues in the boat so it is not as though we have the majority of the crew that won last year, we certainly don't. every year you take it as it comes. that is all the sport for now. now for the weather. last weekend we we re now for the weather. last weekend we were talking about snow and severe winter chill and still the prospect

of snow in this forecast butjust not yet. a typical early spring weekend ahead and the rain eases across england and where is and we see spells of sunshine but also showers and a swirl of the south—west of the uk. the spanish met service have named it storms you go to bring stormy conditions to spain through the weekend but for us it spilled a lot of cloud across england and wales and it continues to bring outbreaks of light rain and drizzle through the afternoon. cloud getting nibbled away. sunny spells and showers for scotland and northern ireland and some of the showers could be wintry. a rumble of thunder to the east of scotland and the best of the sunshine, and here there are highs of 11 and 12. black cloud continues to get eroded from the north through this evening and overnight so there are clearer skies and temperatures take a tumble close to freezing. hanging onto the cloud across parts of south—east england

and southern counties of england and here temperatures up between four and seven. as low as —3 in rural spots. a chilly start the day tomorrow but bright for many and a good deal of sunshine. the one exception would be south—east england, still hanging onto cloud and patchy drizzle. elsewhere spells of sunshine and a few showers and a new food northwest scotland where they could be wintry in nature and they could be wintry in nature and the wind will be fairly light will stop things change next week. it will turn colder again. risk of snow, particularly on tuesday and wednesday. uncertainty around the details so keep an eye on the forecast. monday dawns dry and brighten cold with sunshine through the morning. the sunshine disappears as cloud bills from the western outbreaks the rain in western parts of scotla nd outbreaks the rain in western parts of scotland and wales and northern ireland and south—west england later in the day. ahead of the rain there are highs of ten or 12. we need to

keep an eye on what is happening on tuesday and wednesday because we pick up an east or north—east wind that feeds colder air across the uk and then a prospect we could see some snow. hello and a very warm welcome to dateline london, i'mjane hill. this week we reflect on the european summit and hopes for successful brexit talks. russia was also much—discussed in brussels. and we'll question what can or should be done to regulate social media platforms, in the light of continuing revelations about facebook and cambridge analytica. my guests this week: the guardian columnist nesrine malik. the writer thomas kielinger, a correspondent for many years for germany's die welt. john fisher burns of the new york times. and bronwen maddox, now at the think tank the institute for government, previously with the economist and the times. welcome to you all. so, is there finally some momentum in the brexit talks? at a summit in brussels this week, eu leaders approved the guidelines for the negotiation of future relations with the uk, and while that was expected, observers picked up on a degree of optimism about the whole

process that perhaps hasn't been seen before.
