the labour leader, jeremy corbyn, has delivered a rallying call to his party after last week's defeat in the copeland by—election. he said that, despite the scale of the task, "now is not the time to retreat, run away or give up". mr corbyn was giving a keynote speech to the scottish labour party in perth. here's our political correspondent, tom barton. his report contains flash photography. do you still think you are the man to rebuild labour? jeremy corbyn arriving at labour's scottish conference in perth this morning. we are campaigning for a just and fair society. preparing for his first major speech since the party's historic defeat in the copeland by—election last week. ahead of that speech, in an article in the sunday mirror, mr corbyn wrote:. but he also makes it clear he is not

planning on going anywhere. he said:. labour party, 7000... friday's by—election results saw labour hold the seat of stoke—on—trent central, but the loss in copeland, for the first time in 80 years, has led some to question whether labour can win a general election. those loyal tojeremy corbyn say constant questions about his leadership are hurting the party. one of the issues that people are not voting for us is because they see a divided party. in the last 20 months, half of them have been leadership elections. we look divided. people are quite rightfully saying, it is not about a leadership election, it is about us coming together, listening to people, developing the policies,

but also making sure those policies are communicated in words that people fully appreciate. in scotland, where labour was once dominant, but now faces a massive task to overturn the snp, delegates at the party's conference today backed the party's leader. a lot of people have come back to labour since he became leader. under his leadership, i'm sure we will get back to power. it has not been a great week for us, but we will go forward from that. in his speech this afternoon, mr corbyn will say the result in copeland shows the scale of the challenge facing labour. but he will also try to inject the party with some confidence, saying now is not the time to retreat, to run away or to give up. tom barton, bbc news. and tom is with me now. do you think the speech to scottish labour will have given the party an injection of confidence after copeland? jeremy injection of confidence after copeland ? jeremy corbyn injection of confidence after copeland? jeremy corbyn and those close to him are saying that this is

what the party needs to do, it needs to unite around him to get over some of the problems they are having. this was absolutely his first opportunity to give a rallying cry to the troops, if you like. the loss in copeland was difficult for the labour party. this was a seat in an area that the party has had an mp for eight decades, more than that. and a seat in which in normal circumstances, they would have expected to extend their majority halfway through a spell in parliament where they are the opposition. so to lose that seat and lose it to the conservatives is a big loss. and so, yes, jeremy corbyn's task today was to rally the troops on the one hand, to put forward that argument for unity and he did it pretty passionately. the result in copeland was deeply disappointing and of course, i take my share of responsibility for it. we haven't done enough yet to rebuild trust with the people who have been ripped off and sold

out for decades and don't always feel that labour represents them. but now is not the time to retreat, to run away or to give up. did keir hardie give up the fight? did clement attlee give up the fight? did the miners who fought for better pay and working conditions from the first days of the mining industry? did the upper clyde shipbuilders? the employees, the mill workers and many, many more among the industrial working class who were relentlessly exploited in the workplace? no, they fought back and won, time and time again, to make their lives and all the rest of us who came after them better. that is what we all have to do now, and that is what i will be doing. labour will be campaigning across britain for investment in decent jobs, homes, education for all, support for the national health service, social care and fair taxation. if we stand together, i am confident we can turn back the tory tide and reconnect labour

with working class voters and values. whatjeremy corbyn has not been able to do really is to shake off questions about the sustainability of his leadership. is there any appetite now after copeland for anyone else to take him on in what would be a third challenge? you are right that those questions are still being asked. we have heard them today from some in the party and over the last few days, including crucially from labour's union backers, asking questions about the viability, if you like, ofjeremy corbyn's leadership. all that said, i get the impression there is absolutely no appetite amongst his critics for a leadership challenge. as you say, just a few months ago, about five months, the last

leadership challenge, the second leadership challenge, the second leadership election in as many years occurred, one in whichjeremy corbyn won comfortably and extended his majority. although those questions are still being asked, i don't get the impression that anybody within the impression that anybody within the party wants those questions to be put in the form of a leadership election, certainly, you get the impression thatjeremy corbyn is confident he can retain the leadership. he was asked after his speech today whether he thought he would still be leader in 2020. i'm carrying on as leader because i'm determined that we will deliver socialjustice in this country. we will end the misery of people sleeping on our streets and children growing up in disgusting and disgraceful poverty and growing levels of inequality promoted by a tory government that frankly doesn't care. you'll definitely be leader in 2020? i've given you a very, very clear answer — yes. so pretty bullish from jeremy

corbyn, confident that in a few yea rs' corbyn, confident that in a few years' time, at the next general election, he will still be the labour leader, and i think that very few in the party would disagree with him. tom, thank you very much. some news coming in in the last short while. the actor bill paxton has died following complications from surgery. he starred in a number of hollywood films including titanic, aliens and apollo 13. the 61—year—old actor had two children and was married for 30 years. his family said in a statement, "bill's passion for the arts was felt by all who knew him, and his warmth and tireless energy were undeniable." the new independent review of terror laws has warned that britain faces the new independent reviewer of terror laws has warned that britain faces a continuing and high threat of terror attacks. max hill told the sunday telegraph that plots by islamist extremists to attack uk cities were an enormous risk. earlier, our diplomatic correspondent caroline hawley

explained the significance of the comments. he is essentially underlining the scale of the threat that the uk is facing from so—called islamic state, likening it to being as serious as the threat from the ira during the 1970s. he said there was a significant, ongoing risk, at least as great as that threat in the 1970s when the ira was active. the sad fact is that the threat in this country, represented by what we now know as daesh or so—called islamic state, is high, is continuing, and is not going to abate. how to compare this decade with the 1970s is sometimes very difficult. of course, they are very different threats posed by is and the ira at the time, different ideologies. i think the similarity he is referring to is the intensity at which serious plots

are now being planned. did he say anything about how, as is is being put under increasing pressure in the middle east, for example the iraqi army's operation to retake mosul, whether that has an impact on how is is operating in europe? he didn't specifically refer to that, but as you say, is is in retreat on the battlefield in the middle east, in mosul in particular, and at the same time we have seen an increase in suicide bombings in iraq. we've seen europe attacked before, of course, with the massacres in 2005 in paris, and we know there is an intent to attack the uk. max hill is saying there is no room for complacency, and he is also saying that the british intelligence services have had what he called a truly remarkable success in foiling attacks since the july 2005 bombings. but the main message is that there

is no room for competency, is no room for complacency, there is an ongoing threat that can't be ignored. the singer lily allen has offered online abuse after revealing she had post—traumatic stress disorder after giving birth to a stillborn baby. she began to receive the abuse of mine after speaking about the calais migrant crisis last year. the mother of two's babies were stillborn at six months in 2010. in some of the most shocking twitter abuse, she was accused by online trolls of being to blame for his death. lily allen, who has had a string of hits, has announced she is taking a break from twitter and handed the account to a friend. five people have been injured, three critically, after being hit by a car in south—east london this morning. according to reports, a car struck a wall and collided with the pedestrians. the driver of the vehicle has been arrested on suspicion of causing serious injury by dangerous driving.

round—up from the bbc sportscenter. busy afternoon? lots to look forward to but at twickenham, first, england are looking to make it 17 wins in a row but they have not found it easy so far in the six nations match against italy. england started poorly and they were fortunate not to be behind further on as it —— early on as italy missed two penalties. dan cole forcing the first try of the match to put england ahead. there was a dramatic end to the first half as italy missed another penalty but venditti seized the loose ball and crossed to help the visitors to a 5—point lead at the break. italy went in ahead. eddiejones‘ side had lots to do in the second half and they have responded well with tries from danny care and elliot daly, here. england currently leading 17-10 with here. england currently leading 17—10 with half an hour to go. england look like they are just about turning it around. in the premier league, spurs havejumped into second place after a 4—0 win over stoke. harry kane was the star, with his third hat—trick in nine

games and then he set up dele alli for tottenham's four. adam wild was watching. for tottenham, this is a time for building. knocked out of europe at their temporary wembley home midweek, but it is here this team's foundations have been laid. white hart lane, a much happier home. fitting, then, that once again it was one of their home—grown stars, shining brightest. spurs fans call harry kane one of their own. well, today, he wasn't content with just one. his second came with little over half an hour played. stoke seemingly speechless. for them, this was just one of those days. for harry kane, it was turning into a very special one indeed. a first—half hat—trick, albeit this time with a little luck. but as they say, you make your own and before half—time, he was making won the dele alli. kane's run and cross, 4—0 before the break. construction work outside. inside, this was a demolition. kane could have had

another in the second half were it not for a fine save. still, the applause was all his, as was, eventually, the match ball. spurs up into second, their eighth consecutive home win. premier league momentum building. adam wild, bbc news. plenty to look forward to because it is the first major cup final of the english domestic season later this afternoon, manchester united take on southampton at wembley in the efl cup. southampton have not won a major trophy in 41 years, while manchester united manager jose mourinho is unbeaten when it comes to cup finals in english football. it would be good for the group. 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 to my personal achievements, if you can say that. i am in a period where i am more and more a club man. that is all the sport for now. you

can keep up—to—date with the stories on the bbc sport website and the league cup final kicks off at az30pm. and of course, you can follow the rugby from twickenham where england are still leading 17-10 where england are still leading 17—10 against italy. eddiejones must have had plenty to stay at half—time! it is on the bbc sport website. i will be back in the next hour. britain's four—time olympic champion mo farah has insisted he is a "clean athlete who has never broken the rules." he issued a statement today after a leaked draft report by us anti—doping authorities suggested that alberto salazar, farah‘s coach, may have broken the rules to boost the performance of some athletes. mr salazar has been under investigation since allegations about drugs use at his american training base were made by the bbc‘s panorama programme in 2015. mark daly reports. can there be a one—two for the salazar group? it looks like it as mo farah takes gold for great britain. he's the coach and mastermind behind

britain's sir mo farah and his four olympic gold medals. but alberto salazar and his nike oregon project has been under investigation by the us anti—doping agency, or usada, since a bbc panorama programme in 2015 revealed claims of doping and unethical practices. high—profile us athletes kara goucher and her husband adam made a series of allegations against their former coach. he's sort of a win at all costs person. it is hurting the sport. today, the first glimpse of usada's findings. an interim report by the agency has been leaked by the russian hacking group fancy bears and passed to the sunday times. the report alleges salazar used banned or unethical methods to boost performance including infusions of supplements over the legal limit of 50 millilitres, untested and potentially unlawful medical procedures and medications.

and the report states that mo farah‘s alleged use of an infusion in 2014 remains under investigation. usada said it could:. usada continues to investigate but serious questions now for uk athletics, who were, according to this leaked report, warned about salazar and his methods by one of their own doctors as far back as 2011. salazar maintains his athletes‘ use of medications has always fully complied with the world anti—doping code and in exactly the way usada directed. farah has released a statement saying, "it‘s deeply frustrating that i‘m having to make an announcement on this subject. i am a clean athlete who has

never broken the rules in regards to substances, methods or dosages". he said it was clear from the coverage he‘d done nothing wrong and that if usada had evidence of wrongdoing, to publish it. but questions will persist over fa rah‘s continuing loyalty to a controversial coach the doping authorities seem so determined to pursue. mark daly, bbc news. president trump has said he won‘t be attending this year‘s white house correspondents‘ dinner. the news came in a tweet from 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. joining me now from new york state to discuss this story is the pollster, john zogby. thank you forjoining us. what do you think the motivations are for

donald trump in issuing this tweet and making this decision not to attend the dinner? you know, he has redefined all the rules by breaking all the rules. clearly, for a number of reasons, he really doesn‘t need the mainstream media. he gets the coverage from them anyway but he has his own channels in this era of social media and this era where all of his followers have social media. and so he is not reliant on, say, the washington press corps, as previous presidents had to be. so it is not exactly a symbiotic relationship? perhaps he needs them less tha n relationship? perhaps he needs them less than they need him. it is symbiotic in the sense that they both kind of need each other. he gets his message out, at least to his base and that seems to not be hurting him all that much. frankly, we are redefining what the meaning of hurting someone is. if you play to your base and use the press as a

foil with your base, it actually works for you. meanwhile, the press is covering him and he is the story all the time anyway. so he decides to not go to the correspondents dinner, that is the big story, and thatis dinner, that is the big story, and that is what we are talking about. this is so different fall of us. —— for all of us. i don‘t know that he is long—term redefining the presidency but his presidency is certainly a redefinition. as you say, this will win him approvalfrom his base and it is not going to change his critics‘ mines, and therefore, he continues to be in is very polarising president. he is. now, can he turn all of this into policy? can he turn it into policy that pleases his base? he has raised their expectations considerably. it could very well be barack obama again, with his base, that he gives

pa rt again, with his base, that he gives part of what they want and it is not enough because their expectations have risen. we just enough because their expectations have risen. wejust really enough because their expectations have risen. we just really need to stay tuned. this has been, as you know, all so unpredictable, according to the traditional rules of engagement. ultimately, do you think it is a big mistake for president trump, those closest to him in the administration, to have taken this approach to dealing with, let‘s call them, the more traditional media? i do, personally. but... ido, but traditional media? i do, personally. but... i do, but it seems to some degree to be working for him. now, you know, he has already wrecked, let‘s just say, his you know, he has already wrecked, let‘sjust say, his honeymoon period has been wrecked. is he able to translate this energy and this antipathy towards the press into getting things done, to making policy for his base? that i don‘t

know. but he clearly covets coverage, good coverage, and therefore, in the last question, i was alluding to the fact that it is ultimately a mistake because if he doesn‘t get that kind of positive coverage, along with the negative coverage, along with the negative coverage, that all president should expect, is that ultimately going to bea expect, is that ultimately going to be a huge problem for him as he tries to go forward with his term of office? 0h, tries to go forward with his term of office? oh, i think tries to go forward with his term of office? 0h, ithink so. ithink the way the press deals with donald trump is to a great degree to ignore him. that is the thing, psychologically, that i don‘t think he could stand. he craves the coverage, positive or negative. when he gets negative coverage, he tries to turn it into a positive. and up until now, it has been working for him. what the press needs to be doing is kind of backing away from him and maybe covering other stories 01’ him and maybe covering other stories or going to what really drives him crazy, those unnamed sources. he

hates that! so the next dinner will bea hates that! so the next dinner will be a rather surreal event without the president there. i mean, the last time the president was not there was ronald reagan because he was recovering from an assassination attempt. yes, this is going to be a very strange situation. this is a traditional rite of passage. it is a bonding moment. it is a way to poke fun at each other. it is glitzy. all of that is going to be missed. but i do think that donald trump will be there, very much, he will be talked about the entire evening and the next three days coverage will be all about trump. thank you forjoining us. 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 enforcing 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 reffered to a specialist

service 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, but 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. but the department of health in england says it to make it illegal at the moment. gerryjackson, bbc gerry jackson, bbc news. 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 formal identification of the body. it is almost az30pm. the 89th academy awards take place tonight — 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. by turns dazzling and bittersweet, la la land has a record—equalling 1a oscar nominations. 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 fabulous john legend will be singing, which is really, really great. ryan and emma would have been great, butjohn legend is incredible. well, the big question in los angeles 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‘s 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's not easy for me to admit that i've been standing in the same place for 18 years. i‘ve been standing with you! go find your way over there. that coloneljim is a tall... hidden figures also tackles

racism and sexism — the true story of three women working at nasa has been a huge box—office hit. what happened ? 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 edifies us and shows us a different way of operating and so i definitely think that it‘s going to be a very political year at the oscars. and so we approach the oscars amid talk of politics and protest. in some ways, the world of entertainment has never felt so serious. james cook, bbc news, in hollywood. if you‘d like any more details on the nominees, you can get them all on the bbc‘s oscars page and if you happen to be
