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. jeremy corbyn‘s assertion that he is determined to stay on as labour leader despite defeat in the copeland by—election. earlier andrew marr spoke to the shadow attorney general, baroness shami chakra barti. he asked her to explain jeremy corbyn‘s claim that a vote for the conservatives in copeland was 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 long time. there are peculiarities about that seat, like what was said about our position on the nuclear industry. i don't want to make all about the specifics of copland. we clearly have work to do and have suffered from disunity for the two leadership elections in the space of a year. we have suffered from the fa ct a year. we have suffered from the fact our supporters were divided, like the country, over brexit. now, i think that once article 50 is triggered, we have an opportunity to unite about things that really matter to people about schools, hospitals, jobs and benefits. the deputy labour leader tom watson has called for unity in the party, saying jeremy corbyn‘s champions should stick with their leader. this comes after the general secretary of unison, dave prentis, said while the blame for the defeat in copeland did not lie solely with mr corbyn, he had to take some responsibility. jeromy‘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 not just the with their leader in the bad times and notjust the good. dave prentice has spoken out. where is len mccluskey defending his leader in a difficult time? it should notjust be down to me, defending our leader. if we are going to win this election, we all need to unify. jeromy‘s team need to back him in the good times and the bad. i spoke to our political correspondent, tom barton earlier to get his view of the comments made today. you have two different sides of the labour party. corbin loyalists and those with concerns like the deputy leader, tom watson. they both called for unity they are doing that for slightly different reasons. jeremy corbyn‘s loyalists, his supporters, are sending a message to those with concerns aboutjeremy corbyn. if they upset the apple cart, if they try 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, 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 know they have very little chance of winning any leadership election. their concern is, with mr corbyn as leader, they do not stand a 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. overturned. normally, in a by—election between two general elections, they would have expected to win. jeremy corbyn will say 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 says he was happy with the autopsy report and attention is 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 the cause of death.

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, we suspected from the very outset that it is a form of organophosphorous poisoning because of certain biochemical changes we had 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 a positive 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. a chance for the press and the president to sit down together, put any animosity aside. president trump has decided that this year, he will not attend. 15 presidents have been to this dinner. it has only been skipped on three occasions. that was president nixon in 1972, president carter in 1978, and ronald reagan in 1981. ronald reagan could not go

because of an assassination attempt, and he even phoned in. that is how rare it is for the president to step aside and not attend. but it comes after a number of stepping up of the attacks on the media. president trump has described some outlets as "fake news", and he says that fake news is an enemy of the american people. and then on friday at a white house briefing, certain selected members of the media were not allowed in. that was cnn, the new york times, the bbc, amongst others. 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. earlier i spoke with the conservative commentator tim montgomerie, who gave us his take on president trump's decision not to attend.

i think there is something unattractive in a way when the media and the political class gets a bit too cosy. they all spend a lot of time having lunch with each other, taking each other‘s calls. spreading gossip. there are a flow of people going from the media from different political parties. when the voter feels that their questions or issues are not being dealt with properly and they start to see this cosy and is, that is when i think faith in democracy ebbs a bit. i do not approve of is handling his relationship with the media generally but an end of this particular tradition may not be a bad thing. you mentioned being too cosy. do you think the us media or the media as a whole needs to be reformed? yes. there are suggestions

that donald trump and reporters and journalists are about the same level of public trust. in a way, although donald trump is acting in, i think, an undemocratic way in trying to silence 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 uncovering what is going on. doing the big stories. they are uncovering what is going onlj doing the big stories. they are uncovering what is going on. i think he is probably 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 found the coverage incredibly depressing in many respects. it is

largely about opinion polls and personalities. very little of the issues were covered. there are 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. they should just think, because donald trump is being unfair to them, it does not mean they do not have to put their own house in order. we have seen marine le pen attack the press in france and jeremy corbyn called our own political correspondent ruud. it does seem to be spreading. the bbc often annoys me. i think sometimes it has biases but compared with most other broadcasters, there resources it has, the time it takes to be impartial, there is no other real broadcaster like that in america or on much of continental europe will

stop i am not going to stop as a conservative complaining when i think the bbc is going wrong but it is an institution that plays an incredibly important role in democracy. increasingly, the bbc has been an envy of the world for a long time but more so than ever now. donald trump does not like us. any reporter being invited to white house press reporter being invited to white house press conferences reporter being invited to white house press conferences should wonder if they are doing the job properly. it does seem to be excluding people who are asking tough questions. that is what journalism should be. what will we miss the donald trump not being at that dinner? he was actually quite funny at the dinnerjust before the election, the new york veterans dinner, where he appeared alongside hillary clinton. a little bit of self—deprecation always goes down well with voters. this does involve a roasting of the president, doesn't it? there will be something that will be missed. what will be able to

mistake, there is talk of barack obama, who has done it for eight yea rs, obama, who has done it for eight years, taking his place. that would com pletely years, taking his place. that would completely reinforce the message of donald trump that the press is a wholly owned subsidiary of the democrat party. i have also seen a suggestion that alec baldwin of saturday night live might be a good replacement. that would be a brilliant idea. if any of your viewers have not seen impersonation he does of donald trump, they should get on to 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 a full round up from the bbc sport centre. 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. the wind is picking up a little bit. no roof to worry about at twickenham, of course. if england were to lose it would be the biggest shock in the history of the six nations. fascinating to see how ben te'o gets on. as a finisher, in that win for

england here against france. he is a fascinating character considering nine years ago he was playing rugby for samoa. when he was asked where he was from, he said everywhere you can see his point. he was in australia and ireland before he played rugby union here. he plays with something to prove everything about eddie jones mentality with something to prove everything about eddiejones mentality as a coachis about eddiejones mentality as a coach is keeping the players on their toes, both physically and mentally. with danny care coming into james haskel coming in, those quys into james haskel coming in, those guys have been finishes and they now have a chance to star. he wants at least two, maybe three players in every position he is happy with by the timing and get to the next world cup. absolutely. england have already lost heavily to wales and ireland in particular. not likely to get easier this afternoon but what can the italians hope to gain from this match at twickenham? when you

listen to their new coach, conor o'shea, who knows english rugby very well as irish rugby. he wants them to keep going for 80 minutes, keep their processes and systems. he is trying to rebuild the whole culture of italian rugby union and end this culture of feeling sorry for themselves. when you look back to their last game against ireland, scoring over 60 points, there is an impetus for the opposing team against italy to get to the four try bonus point as quickly as they can. if italy could stop england getting to the bonus point today, that would bea to the bonus point today, that would be a huge victory. as much as italy talk about long—term projects, there is talk about whether they deserve to stay in the six nations come what may. conor o'shea knows he has that short—term pressure as well as long—term reputation in rebuilding italian rugby culture.

there's an early kickoff in the championship — east anglian derby between norwich and ipswich. that game kicked off at midday. it is currently goalless at carrow road. 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. that's all sport for now. i'll have more in the next hour. 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. five people have been injured after a car hit pedestrians in south east london. police and the air ambulance were called at around 8.00 am this morning to bromley road in bellingham after a car also crashed into a wall. five people were treated at the scene and taken to hospital. the driver of the car was detained by an off—duty police officer before being arrested on suspicion of causing serious injury by dangerous driving.

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. just want to go back to that story

about the leaked report suggesting that alberto salazar, the coach of mo farah, may have broken the rules to boost performance of some athletes. he denies any wrongdoing for that we have just had a statement in from mo farah. he says... it is deeply frustrating i'm having to make an announcement on the subject. i am a clean athlete who has never broken the rules in regards to substances, methods or dosages. it is disappointing that some parts of the media continue to try to associate me with allegations of drug misuse. i do understand that using my name in profile makes a story more interesting that it is entirely unfair to make such as when it is clear from my own statements i have done nothing wrong. as i have said many times before, we should all do everything we can to have a clea n all do everything we can to have a clean sport and it is right that

anyone breaking the rules should be published —— punished for that this should be down through proper process. the governing body should ta ke process. the governing body should take action rather than allowing the media did becomejudge and jury take action rather than allowing the media did become judge and jury that statement just media did become judge and jury that statementjust in from the barrack himself. —— mo farah. 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, for chores like babysitting, and with the strength of a dozen samsons 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 £651; 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 oscar nominations. our 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. we are going to pause and get the

weather. good afternoon. the weather is throwing just about everything at us over is throwing just about everything at us over the next few days for that someone us over the next few days for that someone should weather to come as we head into tomorrow. for the rest of today, wet and windy weather the main story. fresh winds on the irish sea coasts. outbreaks of heavy rain as well. in the south—east it will be drier and fairly mild. this evening and tonight some rain moves across england and wales. heavy snow for northern scotland. by the end of the night a real rash of showers packing in from the west. at the same time, temperatures will be falling. that brings the risk of icy stretches. tomorrow morning, some sunny spells but also hefty showers.
