lisbon treaty the formal exit process on the 29th of march. the european commission has said everything is ready for negotiations to begin. mrs may promised to negotiate hard for britain's interests she is stepping into britain's most important negotiation for a generation. huge uncertainty lies ahead. during a trip to swansea, theresa may said her aims were clear. they include putting issues like our continued working together on issues like security at the core of what we are doing. we are going to be out there negotiating hard, in brussels, they've been waiting for britain to make its move. we are ready to begin negotiations. we're waiting for the letter. now we know it will come on the 29th. the president of the european m respond swiftly next week with negotiating guidelines for the 27 countries staying in the eu. so, what's the timetable ahead? talks could then start in may orjune and negotiators have up to two years to try to agree a deal. for ardent brexit campaigners in westminster tonight, the celebrations started early. others though say the prime minister has failed to provide any m across scotland, wales and northern ireland, there is a unity of purpose. that means the prospect of crashing out of the eu without a deal for our economy. this is a big move. whether we like it or not, big change is coming. and i think it's disappointing that the prime minister hasn't tried and other devolved administrations before she did this. theresa may's government faces a monumental task, sorting out a new trade deal with the eu that won't harm british businesses. including leaving the eu with no deal. but they are optimistic about talks. i think it's manifestly in the interests notjust of the uk but of the continuing european union that there should be a sensible resolution of our withdrawal. this vogue magazine fashion shoot released today shows a pensive theresa may. the prime minister today talked about negotiating hard, is it fair to say there is every sign in the european community as well that they will negotiate hard ? european community as well that they will negotiate hard? we did hear very words will negotiate hard? we did hear very - words from jean—claude very tough words from jean—claude juncker at the weekend when he said that when you see the brexit deal and no other country will want to leave, but i think we are in that stage now where the brexit negotiating boxes are in the ring they haven't come based to fist but they haven't come based to fist so but they haven't come based to fist so they try to look menacing and that goes for the uk government with its robust statements as much as for the eu. the eu worries other countries could be tempted out of the door ;;;7,j yet 77 7 ' 77 ' 7 7 7 7 7 "77 7 countries could be

and while the commission will be the lead negotiator for the eu, it commission will be the lead negotiatorfor the eu, it is eu countries that call the shots. there will be a summit in about five weeks

7..7 7.77. 7. the labour party is in the grip of a civil war, according the party's deputy leader tom watson, who's declared that there's a secret plot by left—wing supporters ofjeremy corbyn which could destroy the party as an electoral force. mr watson was reacting to claims that the grassroots momentum group which helped make mr corbyn leader is hoping to get financial support from britain's largest trade union unite. our deputy political editor john pienaar reports. he keeps saying he loves being leader. but could anyone enjoy that? life's tough for labour on a good day, and this was a bad one. as his team gathered together, the party tore itself apart, and his deputy condemned what he called a new and potentially lethal threat. of a secret nlan—by—the—har—d left 7 7 777 using the members‘ money from unite the union to organise within the party. it threatens our very existence as an electoral force in the land — and it needs to stop. momentum is the party leader's army of loyal supporters. its founder, jon lansman, was recorded guiding members to change labour's rules to help another left—winger succeed jeremy corbyn, to pick left—wing candidates and drop others. so, we may well face an election this year, and that will disrupt some of our plans, but we've still got to plan what we need to do next. and what we need to do next is a number of things to change the nature of the labour party. this is the leader's most powerful ally, running can len mccluskey win and help the left tighten its political grip? he has chosen to use his members‘ money to take control of the labour party, rather than develop policies not true, according to the unite leader tonight. this is extraordinary behaviour by tom watson. it's a ridiculous claim. i've not had any meetings at all withjohn lansman on anything, including this latest nonsense that tom has come outwith. this high—level counterattack from mr corbyn‘s right—hand man was remarkable. in the week that the ballot papers go out for the unite election, i think this is about tom's interference in the unite election... why would he want to do that? i think he wants to dominate that. labour's identity is at stake, in a bitter struggle that won't end quickly. the shadow cabinet had what was called a "robust discussion" — there will be plenty more of those. and whether the election comes in 2020, as theresa may insists, or sooner, labour has never looked more torn or vulnerable. jeremy corbyn elected as leader of the... jeremy corbyn won, and won again. unite denies planning to back his most militant allies, but won't say it'll never happen. tonight his deputy won cheers and support from labour mps at a meeting. this fight will go on as long as he's leader, and mayjust continue when he's gone. john pienaar, bbc news, westminster. the former chancellor, george osborne, has defended his decision to accept the post of editor of the london evening standard while continuing as conservative mp for tatton. mr osborne, who's faced calls to step down as an mp, says parliament is enhanced by having mps with different experiences. cctv images have been published of the moment a suspected islamist extremist attacked a soldier at a paris taking control of her automatic rifle, but was shot dead minutes later by other soldiers. no one else was injured. pope francis has asked for forgiveness for what he described as the sins and failings of the roman catholic church during the rwandan genocide in 1994. in november the kigali government reouested an analofiv. .. . from the vatican over the role some catholic priests and religious figures played in the massacres. the president of google in europe has apologised after online adverts for companies and organisations appeared alongside extremist content on you tube. from google platforms. millions of videos are uploaded onto youtube everyday. but they include extremist material such asjihadi propaganda and footage from neo—nazi campaigns. and yet these hate—filled videos attract advertising, often randomly generated. here, a radical islamist preaches about a holiday advert. and here, fascists are twinned. . . . .. an anti—semitic video, but the advert promotes tourism in israel. today, youtube‘s owner, google, apologised. you have probably read stories recently about some brands appearing against content that they didn't want to, and in the spotlight so we'll start by saying sorry, we apologise. when anything like that happens we don't want it to happen, you don't want it to happen and we take responsibility for it. and here's why. a growing list of household names from banks to mediaorganisations - have said they will stop advertising with google until it solves this problem. broadcaster channel 4 is one of those who paid google to promote its programmes. but now it's angry at what has been happening. we specifically asked our adverts not to appear alongside offensive videos, and yet that is exactly what's happened. it is incredibly damaging for a brand like channel 4 to have its adverts alongside neo—nazi and homophobic videos, especially if, we're funding the organisations that made the videos in the first place. advertisers like channel 4 have helped to make google one now they are saying that with that power comes responsibility. google has always said it's a technology company and not a media company. but some of its advertisers are now disagreeing. one of the most influential men in marketing says he recognises that brands, advertisers and tech companies need to work together to control where their adverts go. they have to make sure there is a sort of a whitelist of sites where the advertising can go and a blacklist of where they can't go. that is what we have to work on. i think we will get to a solutiog. = google says it is taking action, but until they break the link between advertising and hate online, internet giants face a level of scrutiny that they aren't used to. the backlash against big tech has begun. amol rajan, bbc news. the un says hundreds of thousands continues an offensive against the islamist group boko haram. food shortages have forced many to flee their homes and farms, putting significant strain on refugee camps. boko haram gained notoriety in 2014 with the kidnap of 292 girls from their school in chibok. but since then it has has been driven out of several areas. the bbc‘s clive myrie has been to the city of bama, which has been largely destroyed by the islamists during years of fighting, and he sent this report. farmers fields in north east nigeria don't yield crops but pity. have been unable to till the land due to conflict. and, on the ground, in the town of bama, bullet—riddled buildings, homes ransacked and lives destroyed. this city used to have a population of close to 300,000 people. now you walk down the main street here and there is nothing but rubble. it's a ghost town, a shell, emptied of life. residents had to flee the islamist group, boko haram. now the grounds of a derelict hospital many call home. this girl escaped the blood—letting. she's 14. translation: they just started killing people and burning houses, so we hide. they said we would be safe, don't be afraid. but when they found us, they caught my father and they killed him. exiles in their own country, the rituals of life continue. but so many people are paying the price for the twisted ideology of the few — that nigeria's camps, this one houses 11,000 people and was so overcrowded with malnourished, new arrivals a few months ago, there wasn't enough food. more than a thousand died. nevertheless, hundreds are arriving at camps like this everyday, as the nigerian military continues to push boko haram back, liberating villages. a mother who had to walk with three her children, from 10pm one evening, and it took until 9am to reach bama. trapped out there with no access, left, you know, to theirfate. what's needed is more international help and crucially farmers being able to till their land. but boko haram is still out there and farmers are scared. planting season begins in less than two weeks. the town of bama is being rebuilt, after the wanton destruction of boko haram. who fled for their lives.

i‘ve had a bottle of wine. and how much would you normally have to drink at the weekend? a bottle of wine. and are you worried about being out and drunk in the street? .__.__7._7_.__._777 d‘you want to know what i worry about? i worry about nothing. but in the last six weeks, volunteers from a community group here have had to call an ambulance for a teenager who was too drunk to walk. and they‘re concerned about what they see as a culture of drinking. we have, "come to ireland and enjoy the drink and the craic." of course there‘s a fun and positive side of that, but when it filters down through to our children, then we have a serious problem. and 20 or a0 years ago, it was 16—year—olds who‘d be drinking. 20 years ago, it was down to 1a. now, we‘re down to 12—year—olds. and that‘s a deep concern for parents. the kids nowadays would buy a bottle of vodka, and drink the vodka raw. this mother is trying to get her 14—year—old help because of her drinking. we‘re not identifying her to protect her daughter. i went to pick her up and she was sitting in the rain, on the grass, on the kerb at the side of an estate, the side of the road and had no idea who i was— she was unable to string a sentence together, unable to stand herself, and for a kid of that age to be in that kind of a state, anything could happen to her. how much do you think your daughter was drinking on a night at her worst? the last night, i know she did drink three litres of cider. belfast street pastors are volunteers who help people who appear vulnerable on the streets. and the police in northern ireland have asked them to extend their hours, to watch out for children as well as adults. normally we‘re out late at night, but they‘d like us to be involved earlier evening, and again, get alongside the kids. they are meeting in sometimes groups of 30, a0 or more. among the people that the police have found with alcohol have been primary school—aged children. off a ten—year—old boy. and some teenagers admit that, for them, alcohol is part of an average night out. there‘s nothing about this nothing, there‘s nothing. that‘s why we go and drink and do whatever we have to do. getting underaged drinkers off the streets is a challenge. and offering alternatives to alcohol is only part of the answer. chris buckler, bbc news, belfast. some of those who served in the second world war have taken part in events at the white cliffs of dover — to celebrate the 100th birthday of dame vera lynn — the singer affectionately known
