but that he is determined to finish the job he was elected to do. in an article in the sunday mirror, he urges his party to stand together to take on the conservatives. he's expected to deliver a similar message when he speaks to the scottish labour conference this afternoon. our political correspondent, carole walker reports. jeremy corbyn is again making it clear he is not standing down and there will be no change of direction. he was in stoke last week when labour saw off the challenge from ukip to hold onto the seat, but he says his party's defeat in copeland was deeply disappointing and he takes his share of responsibility. the tories claimed their victory in copeland was an endorsement of theresa may's leadership and policies. but the labour leader urges his party to stand together, to turn back the tory tide. mr corbyn says places like copeland have been left behind by globalisation. he admits labour hasn't done enough to rebuild trust with people, who he says have been sold out for decades and don't feel labour represents them.

in his article in the sunday mirror, he writes: but his words are unlikely to reassure the critics in his party, who fear they are heading for defeat at the general election under his leadership. earlier andrew marr spoke to the shadow attorney general baroness shami chakra barti and asked her how a vote for the government could ever be considered a rejection of the establishment. in copeland, labour has looked like the establishment for a very long time because they have been represented by labour for a time because they have been represented by labourfor a long time. there are peculiarities about that seat, like what was

said aboutjeremy‘s about jeremy's cheerleaders aboutjeremy‘s cheerleaders made sure he was elected for the second time last september. they should be sticking with their leader in the

bad times and notjust the good. where is len mccluskey defending his leader in a difficult time? it should not just be leader in a difficult time? it should notjust be down for me. we all need to unified. jeremy's team need to back him in the good times and the bad. with me is our political correspondent, tom barton. you have two different sides of the labour party. there were concerns by tom watson. they both called for unity they are doing apple slightly different reasons. jeremy corbyn‘s loyalists, his supporters, are sending a message to those with concerns about jeremy corbyn. sending a message to those with concerns aboutjeremy corbyn. if they upset the apple cart, if they tried to call for yet another leadership election. the last one

was only five months ago and jeremy corbyn won it with an extended majority. the blame for labour's problems will be pinned on those dissenters rather than on mr corbyn himself. really, from tom watson, you are hearing a response from that. among those people with concerns about jeremy corbyn, that. among those people with concerns aboutjeremy corbyn, there is not much appetite for a leadership election partly because they do not think they will win it but because they know that if they do cause problems for mr corbyn, they might find themselves being pinned with the blame. his opponents note they have very little chance of winning any leadership election. their concern is, with mr corbyn as leader, they do not stand huge amount of chance of winning a general election either. he will be speaking in scotland later. do we know what he will say? he will refer to the historic defeat in the copeland by—election. it has been held for many years by the party.

normally, in a by—election between two general elections, they would have expected to win. that loss underlines the scale of how hard labour's task is to persuade people of their message. that result is not what they wanted. now is not the time for labour to retreat, to run away, or to give up. also he will talk about the union and say that actually england, wales and scotland have common interests which are best represented by the labour party. what is required by the people of blackburn, west lothian and lancashire is a challenge to how power is wielded by big business and high finance and says independence does not offer it. the conservative former deputy prime minister, lord heseltine, has said he will rebel against the government when the house of lords votes on the bill giving theresa may the authority to trigger brexit.

the peer says he will support an opposition amendment demanding that mps get a meaningful vote on the deal reached with the eu. police in malaysia have declared kuala lumpur airport — where the half brother of north korea's leader was killed with a nerve agent 12 days ago — to be safe. security officials carried out a detailed search of the terminal building for the presence of vx and other toxic chemicals, but found nothing. the malaysian health minister also said he was happy with the autopsy report and attention was now focused on completing identification of the body. i think now we are more or less completed with the announcement by the chemistry department of the identification of the exact chemical which was involved. we have got the autopsy results. i think those results, along with these, will be submitted to the police. the whole aim of doing an autopsy is to

identify that. that process has been done. ourfindings are identify that. that process has been done. our findings are very much identify that. that process has been done. ourfindings are very much in line with the chemical which has been identified. it is very much in line. in fact, been identified. it is very much in line. infact, we been identified. it is very much in line. in fact, we suspected from the very outset that it is a form of poisoning because of certain biochemical changes we had identified earlier. that confirms oui’ identified earlier. that confirms our suspicions. that part is settled. that information, the autopsy report will be given to the police for them to handle it with the cause of death which certifies what it was. the other challenge facing us is the identification of the body. that is the next process. of course, the best would be to have the next of kin, blood related kin,

where we can do dna profiling. president trump has said he won't be attending this year's white house correspondents dinner. the news came in a tweet by donald trump in another sign of worsening relations with the mainstream press. only three other leaders have missed the annual event, which has been going on for more than a century. our washington correspondent, laura bicker, explained the significance of donald trump's decision to stay away. this seems to be a further deterioration of the president's relationship with the press. this dinner is usually an annual star—studded, glittery event. our editor is still asking for an explanation as to why we were not allowed in, and we are not sure whether or not this will continue. what this message that president trump has put out on a tweet makes clear is that his animosity and his relationship with the press is not going to get any better. let's get more analysis on this.

with me is the conservative commentator, tim montgomerie. is he right to pull out of it? i think there is something unattractive in the way the media and the political class get too cosy. they spend a lot of time having lunch with each other, taking each other‘s all is, spreading gossip. i think, each other‘s all is, spreading gossip. ithink, when each other‘s all is, spreading gossip. i think, when the voter feels their questions or issues are not being dealt with properly and they start to see this cosy and is, i think that is where faith in democracy ebbs it a bit. i do not approve of the way donald trump is handling his relationship with the media generally but an end to this particular tradition may not be a bad thing. you mentioned being too cosy, do you think the us media, or maybe the media as a whole, need to be performed —— reformed? maybe the media as a whole, need to be performed -- reformed? donald trump and reporters and journalists are about the same level of public trust. in a way, although donald

trump is acting, i think, in an undemocratic way in trying to silence his critics, his political tactic is not completely foolish. he is attacking people who already the public do not have a great deal of respect for. of course he thinks it might then neutralise the criticisms when later on in his term they are attacking his achievements or controversies. the new york times and the washington post are still doing the big stories. they are still uncovering what is going on. doing the big stories. they are still uncovering what is going onlj think he is undercutting their authority in the eyes of many americans by suggesting they are out to get him. i was in america for much of last year with the times. i've found the coverage incredibly depressing in many respects. largely about opinion polls and personalities. very little of the

issues were covered. there is a lot of trivial titbits in american media. much more than over here. we are going that way to some extent. the media does have to reform. i don't think they should just think because donald trump is being unfair that they do not have to put their own house in order. it is spreading. we have seen marie le pen attack the press in france for thejeremy corbyn did not want to speak to the press and called our bbc correspondent ruud. the bbc often annoys me i think sometimes it does have biases. compared with most of the broadcasters, the resources it has the time it takes to try to be impartial, there is no other broadcaster like that in america or in much of continental europe. i will not stop as a conservative complaining when the bbc is going

wrong. it is an institution that actually plays an incredible important role in democracy. i think the bbc has been an envy of the world for a long time but more so than. donald trump does not like us either. any reporter still invited to white house press conferences should want if they are doing their jobs properly. it does appear to be excluding the people who ask the tough questions. that is what generally should be to politicians. what would we miss the donald trump not being at that dinner? he was actually quite funny at a dinner just before the election in new york. there was a better instead where he appeared alongside hillary clinton. a bit of self—deprecation with goes down well with voters. he cannot take criticism. this does involve a roasting of the president, doesn't it? there will be something that will be missed. what will be a big mistake is talk that barack

obama should take his place but that would completely reinforce the message by donald trump that the press is a wholly owned subsidiary of the democrat party. the presenter of the democrat party. the presenter of saturday night live might be a good replacement. if people have not seen the impersonation, they should get onto u—tube straightaway. the headlines on bbc news: the labour leader, jeremy corbyn, has said he accepts some responsibility for defeat in the copeland by—election but that he is determined to finish the job he was elected to do as leader. the conservative former deputy prime minister, lord heseltine, has said he will rebel against the government when the house of lords votes on the bill giving theresa may the authority to trigger brexit. police in malaysia have declared kuala lumpur airport, where the half brother of north korea's leader was killed with a nerve agent 12 days ago — to be safe. sport now.

and for a full round up, from the bbc sport centre, here's richard askam. in the six nations, england could overtake ireland at the top of the table if they beat italy at twickenham this afternoon. eddie jones' men have won their first two matches and are red hot favourites to rack up a third victory against the italians. joe wilson is at twickenham for us. england have made several changes to their 15. what sort of impact do you expect them to make? yes, it is interesting. if england we re yes, it is interesting. if england were to lose it would be the biggest shockin were to lose it would be the biggest shock in the history of the six nations. it will not happen in this match is interesting in devell amount of both teams and england. it isa amount of both teams and england. it is a chance to experiment and little bit with selection. remember we have seen ben t 0 make an impact before against france with the late try. he

isa against france with the late try. he is a fascinating character. in 2008 he was playing for samoa in a rugby league world cup. he spent time playing rugby league in australia, rugby union in ireland and finally here to england he has an english mother. he has something to prove. he wants to show he is capable of being a rugby union international. for eddiejones, being a rugby union international. for eddie jones, that being a rugby union international. for eddiejones, that isjust being a rugby union international. for eddiejones, that is just the kind of motivation he likes to see. pa rt kind of motivation he likes to see. part of this reason is to keep players on their toes. to have cu rve balls players on their toes. to have cu rveballs over players on their toes. to have curveballs over selection is part of that. he is giving some of his finishers a chance to be starters. some of these guys might consider themselves to be starters. italy lost heavily to wales and ireland in particular. not likely to get much easierfor them this particular. not likely to get much easier for them this afternoon. what can they gain from the match?m easier for them this afternoon. what can they gain from the match? it is interesting. speaking to the italy coach who has a big reputation in

ireland but also in england, he wa nts ireland but also in england, he wants them to take some pride from this performance will he was looking 0k this performance will he was looking ok after the first half against wales. we had the game against ireland where they got over 60 points. getting the four tries as quickly as they could, it only increase the likelihood of italy suffering some big debates. conor 0'shea is trying to save the mentality of rugby and stop them feeling sorry for themselves what appears on a long—term journey, a long—term plan. even on a long—term journey he needed to show he was heading in the right direction. scoring a try, a couple of tries, limiting england to a0 points, that will count as a victory, i guess. the issues about promotion, relegation, they will not go away. thank you. it's the first major cup final of the english domestic season this afternoon — manchester united take on southampton at wembley in the efl cup. southampton haven't won a major trophy since 1976. jose mourinho, has never lost

a domestic cup final in england. it would be good for the group, good for the club, and it would be good for me, obviously. but, you know, at the beginning of my career, i was looking more to myself and my personal achievements, if you can say that. i am in a period where i am more and more a club man. what is most important is to put in the ground the experience, we can win this game. it is the best opportunity, of course. it is most important for me. boxing now, and amir khan and manny pacquiao have confirmed they will take to the ring on april the 23rd. both fighters made the announcement on social media.

no venue has been given for what khan describes as the "super fight", but pacquiao has suggested earlier this month it may take place in the united arab emirates. that's all sport for now. i'll have more in the next hour. german police are waiting to speak to a man who drove his car into a crowd in heidelberg — killing a 73—year—old man. the driver, who is german, was shot and wounded by police as he tried to flee the scene. police say there are no signs that it was a terrorist attack but the motive is unclear. a leaked report by us anti doping authorities has suggested alberto salazar — the coach of the british olympic champion, mo farah — may have broken the rules to boost the performance of some athletes. alberto salazar has been under investigation since a bbc panorama programme made allegations about drugs use at his us training base. he denies any wrongdoing. health officials have launched a campaign for what they called "a truly tobacco free nhs". recent research shows just one

in ten hospitals is enforcing a ban on smoking outside health service buildings and public health england is urging all hospitals to offer patients help to quit. gerry jackson reports. more than a million smokers are admitted to nhs hospitals in the uk every year. many hospital trusts in england have already banned smoking, but it isn't always easy, and public health england says much more needs to be done to achieve a tobacco—free nhs. according to recent figures, one in four hospital patients in the uk are smokers. but just 28% are asked if they want help to stop, and only 7% are referred for treatment. public health england now wants trusts to ban smoking in and outside all nhs buildings in england and all smokers to be offered help to quit. that might include prescriptions for nicotine replacements, or a referral to a stop smoking support service,

but it also wants a senior clinician employed at every hospital to make sure it happens. if you get referred, your chances of successfully quitting are four times what they would be, compared to if you tried a self—attempt quit. so it goes from 5% to about 20%, which may sound modest, if you repeat this and people try again to quit, after several attempts there's a much greater chance of success. smoking is already banned by law across hospitals in northern ireland and in scotland and wales they are preparing to bring in legislation later this year. the department of health in england says it has no plans to make it illegal at the moment. a £17 million investment for britain's artificial intelligence and robotics industries has been announced by the government. it's estimated the sector could add billions of pounds to the uk economy by 2035, as our business correspondent joe lynam reports.

there may well be a time when robots like this are accepted as part of our everyday life. automatons as gentle as lambs, but chores like babysitting, and with the strength for more ominous services. artificial intelligence used to be the preserve of science fiction, but ai is coming and the government thinks britain will be well—placed to benefit. artificial intelligence is when machines imitate human behaviour and where robots can be trained to take important decisions without being ordered to do so by humans. i'm a sophisticated combination of hardware and software... the department of culture, media and sport believes ai could be worth an additional £65a billion to the uk economy within 20 years. before that, though, the government will spend £17 million on al research, including into surgical micro—robotics, as well as robots capable of operating within nuclear facilities.

some may worry, though, that self—thinking computers could cause more harm than good. others say that this will happen anyway, and it's best that the uk economy benefits from it, rather than losing out. tonight's the 89th academy awards — and there are a few british hopes with andrew garfield, naomie harris and dev patel all nominated. but it's the musical la la land which is tipped for the biggest success — it has 1a 0scar nominations. 0ur los angeles correspondent, james cook's report contains flash photography. # city of stars # are you shining just for me? # hollywood's golden age refashioned for the 21st century. dazzling and bittersweet, la la land has a record equalling 1a oscar—nominations. the film has three big stars. emma stone, ryan gosling, and los angeles itself. we are standing right

where i was sitting when ryan and emma drive up in the car. the woman responsible for the film's breathtaking choreography is now in last—minute rehearsals for tonight's academy awards. we are doing a medley of city of stars and audition. the fabulousjohn legend will be singing, which is really great. ryan and emma would have been great, butjohn legend is incredible. we have got 20 dancers, and it will be very much in the vein of la la land. i think our fans will be very satisfied, i hope. the big question in los angeles tonight is, will the academy opt for the escapism of la la land, or will it choose to confront one of the many serious subjects on offer, in pretty much every other nominated film? there is manchester by the sea, a study in grief, which has six nominations. denzel washington directs and stars in fences, in which a father struggles to bring up his family

in a segregated america. it is not easy for me to admit that i have been standing in the same place for 18 years. i was standing with you! i spent 18 years of my life standing in the same spot as you! that colonel... hidden figures also tackles racism and sexism. the true story of three women working at nasa has been a huge box office hit. why didn't you come home like you were supposed to? and then there is moonlight, with its themes of neglect, drug addiction and sexuality, earning a nomination for britain's naomie harris. really great art reflects society and it edifies us, but it shows us a different way of operating. i definitely think it will be a political year at the oscars. not least when it comes to the documentaries, several of which focus on the war in syria and its consequences. the syrian rescue workers,

known as the white helmets, say they will not fly to la for the oscars, amid reports that they would have been refused entry to the us. i think all we need to focus on right here is that these people are heroes, they are some of the most brave humanitarians in the world, and they were nominated for a nobel peace prize last year. if those people are not welcome on this soil, then there is a real problem. and so we approach the oscars amid talks of politics and protest. in some ways, the world of entertainment has never felt so serious. james cook, bbc news, in hollywood. time for the weather. plenty going on with the weather over the next couple of days. in the west things will turn cloudy, wet and windy. some heavy bursts of rain in northern ireland, western

scotland, england and wales. we could see gusts of 60 miles an hour to the exposed coasts. some cold air tucking in full in the south east some limited brightness and a fair amount of cloud but it will stay fairly mild. this evening and tonight a band of rain pushes across england and wales snow moving north across scotland. lots of showers packing in by tomorrow morning which will give the risk of icy stretches. some hefty showers with hale, thunder, sleet and snow. wintry mostly over high ground. feeling colder than it has done recently. hello, this is bbc news. the headlines at 11.30am. jeremy corbyn has said he accepts some responsibility for defeat in the copeland by—election — but that he is determined to finish the job he was elected to do as leader. he's due to speak later today. the conservative former

deputy prime minister, lord heseltine, has said he will rebel against the government over brexit — when the lords vote on article 50 — the bill giving theresa may the authority to start negotiations to leave the eu. police in malaysia have declared kuala lumpur airport — where the half—brother of north korea's leader
