elderly men in exeter. and at 11:30 we'll be taking an in—depth look at the papers with our reviewers — the broadcaster john stapleton and the uk correspondent for france 2a benedicte paviot — stay with us for that. good evening. donald trump has defied his critics, and many in his own party, by declaring a national emergency to bypass congress, to get the billions of dollars he says he needs, to build a border wall with mexico. it means he can redirect funds from other government departments. at a news conference at the white house, he said a barrier was needed to stop an "invasion" of drugs, gangs, human traffickers and undocumented migrants. however democrats say the move is unconstitutional, because the president has exaggerated problems on the border, to try to fulfil a rash campaign promise ,and they'll fight him all the way to the supreme court.

our north america editor jon sopel reports. ladies and gentlemen, the president of the united states. donald trump faced a choice that was pretty unpalatable, he was either going to admit defeat, there wouldn't be the funds for his wall and the democrats would have won, or he could choose the nuclear option and declare this national emergency. we are going to be signing, today, and registering, national emergency. and if's a great thing to do, because we have an invasion of drugs, invasion of gangs, invasion

people, and it's unacceptable. watched by relatives who have had family members killed by illegal immigrants, the president rode roughshod over the powers of lawmakers to set budgets and to set up lawmakers to set budgets and to set up they conversation that he fully recognises is likely to end up in the courts. we will have a national emergency and we will then be sued and they will sue us in the ninth circuit, even though it shouldn't be there. and we will possibly get a bad ruling and then we will get another bad rhule, and then we will end up in the supreme court —— ruling. all the time the courts are deliberating it means there will be no substantial building work taking place. less building awol than hitting one. but he's the problem. there's a lot of of fencing and structures but there are places where it just ends, structures but there are places where itjust ends, so people like his mother and child from what allah can walk around it. —— from what mahler. "my little girl is hungry,",

she says, "and i don't have any money." most of the drugs that entered the country from mexico come from legal crossing point, like this one. but a lot of border patrol officers who backed the present‘s call for a wall make this problem —— makers call about the problems of saving. it has changed. but that is the equivalent of saying your house is only getting robbed one day out of the week rather than all seven. we are not done. back in washington the democrats are considering their next move. it is hard to believe they won't challenge this. president trump and convince mexico, he couldn't convince the american people, he couldn't their elected representatives to pay for his ineffective and expensive wall. make no mistake, congress will defend our constitutional authorities in every way that we can. donald trump's signature is now on this declaration. there are many on both sides of the divide the question how

much of a national emergency this really is. and it won't be lost on them that on day one of the emergency the president flew off to his golf course in florida, not the border in mexico. jon sopel, bbc news, in washington. i've been talking to our correspondent dan johnson, who's on the us—mexico border — near san diego. their primary plan of the president is if you shore up the border wall, com plete is if you shore up the border wall, complete the wall across most of the border, then you can funnel people, the goods, the crime that he is talking about two border crossing points like this —— the primary plan. you can also come he reckons, free up the border control agency lappi minute chasing people across hillsides, the open desert, wherever there isn't a wall, to focus their attention in europe so they can intercept more of the drugs, the criminals, and meet the asylum seekers, because currently there are about 1000 people who cross illegally every single day, many

from central america, seeking asylum in the us. there is a huge backlog. border patrol doesn't know what to do with those people. they wait two or three years to have their future actually be done. everyone seems to agree that that situation is untenable. it may not be the crisis, the emergency, the disaster that the president has described it as, but certainly things do need to change and even the democrats admit that. that is why they have proved more than $1 billion funding to improve technology and border protection across as border. but it is way short of what president hollande. he is $4 billion short of the funding needed to complete the wall —— the president wanted. that will free up funds from other places which he says it is to be used to finish that wall. there are people on his own side disappointed that he wasn't able to make that deal in congress. that he has taken it to this level, that he has raised the stakes so high. and the democrats are com pletely high. and the democrats are completely opposed to this. president trump himself admitted

this will now be tied up in legal wrangling trying to work out whether he has actually acted lawfully in declaring an emergency or not. he himself admitted, in his press conference, "i didn't need to do this, it was just the quickest way of getting the money i need to do is this wall". dan johnson there. the family of shamima begum, the british teenager who joined the islamic state group in syria, say she should be allowed to come home to britain. in a statement tonight, they said they'd "lost hope of ever seeing her again" and "as a british citizen, she has every expectation to be returned to the uk". but the home secretary sajid javid has suggested he may prevent those who'vejoined is, from ever coming home, on national security grounds. our home affairs correspondent daniel sandford has the latest. inside this camp in northern syria, and the women and children who fled from the fighting in one of the last strongholds of the islamic state group. this is where the former

bethnal green schoolgirl shamima begum is staying, along with other british women who've been with is for four years or more. tonight in a statement they asked the british government to help them return her, along with her unborn baby. this is what they said. her child, who will also be british, has every right has a total innocence to grow up in the peace and security of this home. they said they would welcome the police investigating her, something that is inevitable if she returns. we have to be clear that people who leave this country to support that regime are people who, if they do return, have two ads for their actions. some 850 people left the uk to join islamic state and around half have already come back. today alex younger, the head of the secret intelligence service, mi6,

warns that some would pose a risk. he said this. the home secretary said this morning that he would prevent those involved in terrorism to return to britain. what is aiming for shamima begum, who left as a schoolgirl? clichy have hurt citizenship seven wait? —— which she have her citizenship. she doesn't have her citizenship. she doesn't have another nationality it is morally unacceptable to refuse entry as well as legally unacceptable. because otherwise she would be stateless. and no person in the world can be stateless under the law. her family said they were shocked to hear her say that she did not regret going to islamic state. they suggest you were screened at the age of 15 and might have been wa ry the age of 15 and might have been wary of what she was saying in a camp surrounded by an islamic state sympathisers —— she was groomed. an

expert in de—radicalisation says i am supporters can be turned round. we know in the uk we have worked in the last ten years with fairly hard—line violent extremists who have renounced their ideology, have remorse for their actions, and have taken part, actually, in helping others move away from extremist tendencies and violent ideologies. the kurdish red crescents as there are around 1000 new arrivals are just this morning. decisions will have to be made soon about what to do with the british islamic state supporters among them. daniel sandford, bbc news. a man has been charged with the murder of three elderly men in exeter. alexander lewis—ra nwell who's 27 and from croyde in devon, will appear in court tomorrow. he's charged with murdering 80—year—old anthony payne who was found dead at his home on monday ——and 84—year—old twins dick and roger carter — who were discovere just over a mile away, the following day.

schoolchildren across the uk, have been taking part in a day of protests, calling for action on climate change. organisers say pupils walked out of schools in more than 60 towns and cities to highlight what they see as a lack of action by the government. manchester, is one of the places where children took to the streets, from where frankie mccamley reports. we are angry that the government's not doing anything, but we also see it as important to fight for ourfutures. to all the politicians, listen to what we have to say. you failed at saving your own future, so now can you try and save ours? there's no time to rest. we have to do something to save the planet. chanting: this is what democracy looks like! different voices, one clear message. today was a day led by the children, for the children and their future. thousands campaigned in dozens of protests across the country. they say you don't have a voice!

a call for action in sheffield... what do we want? climate action! chanting in ullapool. .. marching in brighton... a real sense of urgency in cardiff and, in manchester, there was music. before nine—year—old lilia had her say. i'm worried about climate change because of the animals. would you like it if your home was disappearing in front of your eyes? this is clearly the first time many of these pupils have ever walked out of school and, just by looking at the age of some of these, the first time they've ever been on a protest, but their message is clear. they want to protect the future of the planet and safeguard their future. the action is part of a much wider global movement, inspired by 16—year—old greta thunberg from sweden. she's been striking from school every friday, calling on her government to lower its carbon footprint. you are not mature enough to tell it like it is.

even that burden you leave to us children. her persistence later sparked protests across the world, from australia to belgium and ireland earlier this week. the government has said today's protests are a waste of lesson time and increasing teachers' workload, but the threat of school disciplinary action pales in significance to the danger these youngsters think the planet is under from climate change. frankie mccamley, bbc news, manchester. i was joined in the studio a little earlier by 15—year—olds george and scarlett. they were responding to some critics who have suggested they should have been at school today, rather than taking part in protests. i value my education incredibly highly. i care so much about school and have every intention and plans

to catch up with all the work i have missed. and the reason, and the fact that i value my education so highly is linked to the fact that i value my future so highly. and this is just another way that i am, kind of, fighting for my future. how do you see your future? what is it look like you? at the moment it is extremely unpredictable and unstable. and that is concerning for all of us. we hope that we are taking action for a future that will not be devastated by the climate crisis we are facing. but at the moment we cannot be certain of what the consequences will be if the apathy continues. there is apathy, and a lot of times, because people don't know how to start looking at climate change. to you both appreciate that there are so many pressures on governments around the world is in terms of tackling climate change? -- do you both? i think we can both understand it is incredibly intimidating to deal with an issue like this which is notjust

social and cannot be fixed with a conversation. it is about our whole world, but we have to unite on this. because this is the existential threat of our generation and we must deal with it in less than, we must fix it in less than 12 years. 0k, george, how do we deal with it, what would you like the government to do? we have four demands. the first is for the government to immediately declare eight climate crisis. our second and third demands involve reforming the national curriculum. our fourth and is the centralisation of youth and student voices in climate dialogue, which is essential, and the voting age of 16, which is essential for our voices to be heard on the most relevant dialogue of our generation. he didn't want —— need more education in this? you say the curriculum needs to be adjusted to include climate change at school. is that the children or the adults who need educating? i think it is definitely

all of us. it is an issue we all need to understand more. to an extent, it is certainly a government that needs educating, because we can see that the issue is that and that we will have to deal with it, but they seem to be blatantly ignoring they seem to be blatantly ignoring the severity of it. ok, what do you both make then, since 2015, essentially, no policies have been implemented by most of the governments that signed up to the paris agreement? it is shocking, but perhaps unsurprising to many. we understand that often breed and a lack of political will translate into a lack of political action —— greed. that is why it is so important to stand up for our voices and we say we won't lie down and allow governments to trample on the security of our futures. george and scarlett there who joined the earlier to discuss those climate change protests across the country earlier today. the headlines on bbc news: president trump confirms he will invoke emergency powers

to pay for a border wall with mexico. the family of the british teenager, shameema begum, who ran away to join the islamic state and now wants to come home to have her baby, call on the government to help her return to the uk as quickly as possible. thousands of pupils skip school and take to the streets in protest against climate change. the indian government says pakistan will pay a heavy price, after a suicide bomb attack in kashmir which killed more than 40 indian security officials. a separatist militant group, jaish—e—mohammed, has claimed responsibility, and pakistan denies any involvement. kashmir has been a flashpoint between the two nuclear—armed states for decades, leading to three previous wars. the area is divided between them, but each claim all the territory as their own. the latest atrocity, the deadliest for almost 30 years,

has led to fears of another serious confrontation. from new delhi, our correspondent sangita myska reports. these are the anguished families, grieving for the fathers, sons and brothers killed in indian—administered kashmir‘s worst terrorist attack in recent history. their coffins carried by soldiers and the paramilitary force was yesterday at became a target. the two great nuclear powers in the subcontinent, india and pakistan. the aftermath of the attack was caught on camera. this was all that was left of a bus, part of the huge military convoy. this is said to be the suicide bomber. one of a new

generation radicalised in a region where the majority of the population is muslim. the islamist militant group jaish—e—mohammed has claimed responsibility. based in pakistan it has been fighting for independence for kashmir by 20 years. it says it has in contra vertebral evidence that pakistan was directly involved. translation: want to tell the terrorists and their patrons that they have made a huge mistake and they have made a huge mistake and they will have to pay a huge price that is. pakistan strongly denies the accusation and has accused india of carrying out human rights violations in the past. the two countries have fought three wars over who should control kashmir to stop india has hundreds of thousands of troops stationed here but security is getting worse. after the last major attack two years ago, it launched military strikes inside pakistan. this attack has enraged

many indians who are convinced pakistan is trying to destabilise their country. protests like these are happening in several parts of the country and are helping to build pressure on the narendra modi government to take decisive action. if they act like that, whether directly or through terrace we need to show our strength and retaliate. it is acceptable in a civilised society. tonight, as the prime minister laid a wreath, the question is what will his next step be? sangita myska, bbc news. next week mps looking into disinformation and fake news, are expected to publish their final report into the way our personal data has been sometimes manipulated for political influence, at the highest levels of power. and it's happening right around the world. here's our media editor, amol rajan. when you report fake news,

which cnn does a lot, you are the enemy of the people. in just a few years, the phrase "fake news" has entered mainstream culture. then they've got the nerve to say we're fake news. you and your colleagues have fallen into this trap of fake news. it's a calculated and corrosive term, often deployed by those trying to discreditjournalism, but the term fake news captures an urgent issue confronting modern democracies — disinformation in the digital age. in america, authorities are investigating social media's role in russian interference in the presidential election of 2016. the nearest thing in britain is the house of commons select committee enquiry into disinformation and fake news. over the past year, it has taken evidence from regulators and tech companies and those at the centre of allegations around the targeting of voters during the brexit referendum. the enquiry is looking at four areas in particular — first, whether social media firms

are neither platforms nor publishers but a new kind of company which has legal liability for harmful or illegal content. then there's the issue of electoral law. the committee wants new rules for digital campaigns, not least around the issue of shell corporations being used to hide identities. next, what was the precise role of cambridge analytica? the committee has looked at the impact of the british data firm and has said its ceo misled them. finally, there's the kremlin question — to what extent, if any, did russia weaponise information during the brexit referendum, and why is there such a gulf between the government's warnings about security and the response of tech companies? facebook is taking disinformation more seriously and has appointed the charity full fact as its first independent fact—checkers in britain. one thing i'm aware of is it might not be facebook in ten years' time, or it might not just be facebook. we're going to need to write rules through open, democratic, transparent processes that apply to all these companies.

last year, facebook was fined the maximum half a million by the information commissioner for serious breaches in data protection law. have you seen satisfactory evidence that they've learned and changed? i am hopeful that we'll see more of that change. that suggests we haven't so far. i haven't so far. i think it's yet to be seen. what do they need to do to comply with this regulatory regime which they are currently not doing? it's not good enough to say, here's what we're doing. we need a proof point and we need... facebook can't mark their own homework. social media platforms like to think they're a benefit to democracy. across the west, that's in dispute. amol rajan, bbc news. there have been numerous tributes to the award—winning author, andrea levy, who's died at the age of 62. she'd been receiving treatment for cancer. she made her name with the novel small island about the windrush migrants,

who in the late 1940s moved to britain from jamaica, and she was widely regarded as the first black british author, to achieve both critical and commercial success. lizo mzimba looks back at her life. the empire windrush brings to britain 500 jamaicans... in 1948, andrea levy's father arrived on the empire windrush, the inspiration for her novel charting the hopes and struggles of a generation, small island, which won multiple awards and was adapted for tv and the stage. when it came out, i said to the publicist, "just give me a basket, i'll take them door—to—door". i really thought nobody would be interested. you think your white skin makes you better than me, don't you? we both finished fighting a war for a better world. we were on the same side. if anybody wants to have a look at how the windrush generation arrived here, and how we, the sons and daughters of that generation,

survived and are surviving, they have to refer to andrea's work. that's why, for my generation of black people in this country, there's always a andrea levy book on our bookshelves. andrea levy had grown up in london, and in her 30s had begun to write. her work was driven by her own curiosity about where she'd come from. it was a story which eventually took her back to britain's role in the caribbean slave trade. for every one slave who went to america, 12 went to the caribbean. it was massive. i have seen books on british history that don't mention slavery, you know, and you just sort of... it beggars belief. the character she created was a house slave who bore a child to an estate master, and later, she discovered that that was the story of her own great,

great grandmother. andrea levy, an author whose life and work was rooted in the story across generations of two small islands, britain and jamaica. andrea levy, who has died at age 62. jackie kay is the national poet of scotland. she knew andrea levy well. it is terribly sad. it is always a great lost when someone like andrea levy dyes. she was very, very young. she didn't expect her own death. the last 15 years she had cancer and she knew she was dying and she lived against the clock in a different kind of way. people who know they are dying have a heightened reality and paradoxically life can sometimes

be more rewarding because every moment is a precious moment and you are not wasting time. how did you meet her? festival a matter of any being talk of small island, for the orange prize. and that was a really exciting and then she came to newcastle university where i am a professor and chicane with the long song and the whole of the campus we re song and the whole of the campus were reading that book, notjust inside the campus but outside, everybody but everybody. the university gave out 3000 free copies in conjunction with the booker prize and the idea behind the big read was to get everybody reading the book whether they were english graduates, people at the fruit and veg. andrea laughed at that initiative and it was up the street and chicane with

people from the booker and i interviewed her in front of 900 people. she hoped she was not going to get academic question because she was a bit sick. and yet she came across as such a charismatic lady. what was she most proud of? and think she was staggered by the success of small island. when she was writing it she did not know if the publishers would even publish it. she had written three books previously at they had not sold well. she was staggered by the success of small island, it allowed her to pay off her mortgage and not have the anxiety that many writers have the anxiety that many writers have when they are writing. now it's time for the weather with ben rich.

friday was the sort of day that might have left you scratching your day wondering if it was still february. the weather stays pretty mild. not always as mild as this. in fa ct, mild. not always as mild as this. in fact, we went to 17.5 degrees in parts of north wales on friday afternoon because of these warm air wafting up from a long way south. really mild for this time of year. many of us asked in sunshine. more cloud across western and northern parts of the uk and i think cloud will be a bigger feature of the forecasts over the weekend. quite a lot of cloud over southern england. cloud over western areas as well. north—east england and scotland seeing the best of the sunshine. it will be quite a breezy day but again a mild one, even when you stick with

clouds, highs of 11 up to 15 in the sunnier parts of eastern england. on sunday, high pressure across a big pa rt sunday, high pressure across a big part of europe blocking weather systems trying to push in from the west. these fronts moving in will not sweep through neatly gets stuck running up against the block of high pressure so shift across the western side where we will see splashes of rain. further east dry with some sunshine. temperatures again around 15 degrees. low pressure in charge at the start of the new week. it may be that a ripple runs up this front and brings some cloud and patchy rain in the parts of the midlands, east anglia and the south—east. also
