preparations are all most complete as hollywood prepares for the biggest night in film, the oscars. la la land is expected to the big winner, with m nominations, including best picture and best director. and, coming up at 10:30: more oscars build—up, with everything you need to know about the academy awards, in talking movies. good morning and welcome to 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. 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. with me is our political correspondent, tom barton. earlier, i asked earlier, iasked him earlier, i asked him over questions hanging overjeremy corbyn‘s leadership. this was a defeat in a labour stronghold in a seat which, halfway between two general elections, they should have expected to wind. jeremy corbyn, writing in the sunday mirror today, recognises that he has a share of

responsibility to take for that defeat, but at the same time, he says he is determined to finish the job of labour leader. he signals that there will not be any change of direction for the labour party. he points out, as you saw in that report, he won the leadership election five months ago with an increased majority. there is that you no appetitejeremy corbyn‘s part to go anywhere. as for his opponents, you get the sense there is no appetite for change amongst them either. they recognise that they have very little chance of winning any attempt to oustjeremy corbyn. but they also worry that perhaps the labour party does not have much chance of winning a general election if he stays. we will hear from general election if he stays. we will hearfrom him later today general election if he stays. we will hear from him later today at scottish labour, so it is really the first fallout he has had since all of this arose. he was not answering many questions yesterday. this is the first major speech that he has given since those by—election

results on friday morning. he will speak to the scottish labour conference. and of course he is in scotland, a place where labourface, if you like, their biggest challenge. at the last election, they lost what was effectively a stranglehold over electoral politics in scotland, and they were all but wiped out. if you want to see the challenge faced by the labour party, there is no better place to look down scotland. the question for jeremy corbyn is whether he is going to be able to overturn the snp stranglehold in scotland, and whether he can do something similar in england with the conservative support there, because frankly, if he wants to become prime minister, he wants to become prime minister, he needs to do both of those things. 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. we have now more or less completed the announcement by the chemistry department of the identification of the exact chemical involved, and we have got the autopsy results. i think that result along with this, will be submitted to the police. the whole aim of doing an autopsy is to identify the cause of death. so that process has been done, and our findings are very much in line with the chemical, which has been identified.

it is very much in line. in fact, we actually suspected from the very outset that it is a form of poisoning because of chemical changes we had identified earlier. so that confirms our suspicions. so that part is settled, so that information, the full autopsy report will be given to the police for them to handle it, with the cause of death. the other challenge facing us, of course, is the identification of the body. that is the next process. of course, the best will be to have the next blood—related kin, so 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. also in the united states, democrats have elected a new national chairman. tom perez is a former member of barack obama's cabinet. he acknowledged that the democrats were facing a crisis of confidence following the election of president trump, but said

the party would succeed if it led with its values. some day they are going to study this era in american history, and they are going to study it, along the know—nothing movement. they will ask the question of all of us, where were you in 2017 when we had the worst president in the history of the united states? and we will all be able to say, whether you are sitting here, whether you are sitting outside, or whether you are looking on across america, we will all be able to say, the united democratic party led the resistance, ensuring that this president was a one—term president in elected democrats across this country. at least 28 people have been injured in new orleans after a suspected drunk driver ploughed his car into a crowd of people at the annual mardi gras parade. 21 people needed hospital treatment. russell trott reports. it's the biggest parade in the new orleans mardi gras festival.

it attracts big crowds, but all eyes quickly turned to a pickup truck. according to eyewitnesses, it went by in a flash before ploughing into other vehicles. the families gathered on the roadside didn't stand a chance. among those injured, children as young as three. it happened in a matter of seconds. we heard impact and people were scattered. we suspect that the suspect was highly intoxicated. he is in custody and he is being investigated now and is in our main office. an eyewitness said the driver seemed disoriented and possibly drunk and didn't appear to realise what he had done. the man has now been taken into police custody. the sense of shock and disbelief here, only tempered by the realisation that this is unlikely to have been a terror—related incident. german police are waiting to speak

to a man who drove his car into a crowd in heidelberg, killing a 73—year—old man. two people were injured. 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. 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.

compared to if you tried 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. 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 £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. the headlines on bbc news:

the home side responded with 20 u na nswered the home side responded with 20 unanswered points, including two tries, a crucial second one finished off there. they are a very good team, and wales are a good team as well. we go to england for the next game. we genuinely believe we can win if we work hard. after their defeat to scotland, ireland have won back—to—back matches. so here's how the table looks. the new bonus point system puts ireland one point above scotland. england have the opportunity to go above them both this afternoon. they play italy at twickenham. the italians have lost their opening two matches and conceded 96 points, but the england skipper says they should expect a tough contest. the focus has been this week very much on ourselves, what we can control, what we can get right,

focus on the basics, play with an intensity that can, you know, put italy under pressure, but we have got no doubt it will be very confrontational at the start of the game, and they pose a big threat, especially early on. 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 mourniho, 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 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, looking more to myself and my personalachievements, if 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. chelsea have extended their lead at the top of the premier league to 11 points after a 3—1win over swansea city at stamford bridge. cesc fabregas marked his 300th premier league appearance by firing the blues ahead. fernando llorente equalised before the interval. but after the break chelsea swept swansea aside with goals from pedro and diego costa. the other teams asked us to play, but it is important to look at ourselves and to think we will win. around this part of the season, every win is very important for us. elsewhere, crystal palace beat middlesbrough 1—0,

to move out of the relegation zone, but sunderland remain bottom after losing 2—0 to everton. hull city and burnley drew 1—1, as did watford and west ham. west brom beat bournemouth 2—1. boxing now, and amir khan and manny pacquiao have confirmed they will take to the ring on april 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. london 2012 silver medallist michaeljamieson has retired from swimming. jamieson‘s silver medal in the 200m breaststroke was the best british performance in the pool in the home olympics. he struggled with depression after injuries and was disappointed with his silver two years later at the glasgow commonwealth games. he's now heading to guatemala to learn about yoga and meditation. i will have more sport for you in

the next hour. back now to our top story, jeremy corbyn‘s assertion that he is determined to stay on as labour leader, despite defeat in the copeland by—election. he claims the boat was the rejection of the establishment. andrew marr spoke to baroness jakubowski and asked her why the vote for the parliament could ever be considered a rejection of the establishment. in copeland, labour has looked like the establishment for a long time because they have been represented by labourfor a because they have been represented by labour for a long because they have been represented by labourfor a long time. there are peculiarities about that seat, like what was said about our position on the nuclear industry, and so on, but i don't want to make it all about the specifics of opened. we have clearly got work to do. we have clearly got work to do. we have clearly suffered from disunity. to leadership elections in the space of a year. we have suffered from the fa ct a year. we have suffered from the fact that our supporters were divided, like the country, over brexit, and that has been such a big it issue for such a long time. once

article 50 is triggered, as it will be, we have an opportunity to unite about things that really matter to people's lives, like schools, hospitals, jobs, benefits. the red carpet‘s been rolled out for the biggest night in hollywood. 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 naomi 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. people are being asked not to get too close to a humpback whale which has been spotted off the coast of south devon. it's been seen in start bay near slapton, and is believed to be with a calf. crowds have been drawn to the area, but the bay is being patrolled by police. they're warning anyone caught harassing the whale could be prosecuted. a0 humpbacks have been seen off the uk coastline in the past year which is a record high. they may not seem like the most

obvious pairing, but rugby league and ballet have come together in a unique experiment. the wigan warriors academy team have turned to ballet training to help improve their performance on the field. players have started to perfect their pirouettes as a way of increasing their strength and reducing injury, as ian haslam reports. music from swan lake moves often choreographed in training characterised by light, graceful technique. go high. moves like this are also choreographed in training and characterised by light, gracefultechnique. yes, there are more similarities between ballet and rugby league than you might think. and peel the foot off the floor... of course it is easier if you are not wearing a suit. as soon as we got told it wasn't a joke and we were actually going to be doing this,

i just jumped right in. i thought it was for girls, but when i tried it, it was really hard, it surprised me. just like on the pitch the under 19s' hard work has paid off away from it. the improvement in such a short time, they're sports people and theyjust want to be good at everything, including ballet. this is alan, pianist and pioneer, the brainchild behind the ballet. we set it up with warriors. surprisingly they agreed, which was incredible. we're off to see the royal ballet on thursday at covent garden. so, could sean wayne's newly crowned world champions follow suit? we have taken a massive interest in this, the first team, and i wouldn't be surprised if they started incorporating this into their recovery too. a regime which may even help them stay in first position. germany's bombing campaign against britain in world war two lasted for eight months and killed 43,000 people. but despite the heavy bombardment,

two police officers managed to document the devastation through a series of photographs. now those rarely seen images are going on display at an exhibition in london. our reporter caroline davies has been to see them. here again are the same firefighters who face peril and danger with determination courage. london during the blitz. a newsreel showing resilience and heroism. the museum of london exhibition shows a different side to the destruction. alongside paintings from well known war artists, some unexpected contributors. two city policemen. they were recording the damage to the city. partially with the name of recording it so they could think about reconstruction work afterwards. it is not known if these images were ever used to help rebuild. the destruction was potentially too great. london has been wounded during the hours of darkness. but what colossal strength runs through her veins. even today, many of the images we usually see of the blitz

were recorded as propaganda. but these images were never meant to be seen by the public. a coat still hanging on the back of a door. they show a different side to the devastation. less defined, more private. bookcases intact in a sitting room ripped apart. london did rebuild after the blitz, often along the same street lines that existed before. what's striking about these photographs is that they show a city so familiar, destroyed in a way that none of us have ever experienced. you cannot help but look at the images of the bomb damaged cities without thinking about current political events. it is inevitable, i think. this new exhibition shows a city destroyed by war, this time without the fanfare. caroline davies, bbc news. time now for the weather.

hello. plenty going on with our weather over the next couple of days. we will see some sunny spells in eastern areas today, but further west things turning cloudy, wet and windy with heavy bursts of rain to northern ireland, western scotland, north—west england and wales. with that, strong winds, up to 60 mph on some exposed codes. some smoke in northern scotland. ltd brightness in the south—east. it will state fairly mild. this evening and overnight, rain racing across england and wales, snow moving across over parts of scotla nd wales, snow moving across over parts of scotland. lots of showers packing in by tomorrow morning, giving us the risk of icy stretches in north—western areas first thing. through tomorrow, some hefty showers, with hail, founder, some sleet and snow. mostly over higher ground, but when
