from the world economic forum. that's in "the world debate: davos, the fake news challenge to politics." that's in 15 minutes. good evening, and welcome to bbc news. president trump has predicted a "tremendous increase" in trade between the uk and the usa. after a meeting with theresa may at the world economic forum in davos, the president dismissed talk of growing differences between britain and america, not least on the global terror threat. our north america editor, jon sopel, reports from davos. in a blur of rotor blades, a swirl of snow, and a near avalanche

of expectation, donald trump blew into davos today. not his natural environment. it's very exciting to be here, we are very happy to be here. the united states is doing very well. but he came with a message. he had come to spread peace and prosperity. this is not exactly daniel into the lion's den. donald trump and the davos set are not exactly natural soul mates, but nevertheless, the world economic forum has come to a virtual standstill. mr president, are you looking forward to your meeting with theresa may? after their spat over those anti—muslim britain first videos and his cancelled trip to london, they were falling over themselves to be nice. problems in the relationship? a false rumour, said the president. thank you very much.

it's an honour to be here with prime minister may. we have had a great discussion. we are on the same wavelength, i think, in every respect. the prime minister and myself have a really great relationship, although some people don't necessarily believe that, but i can tell you, i have tremendous respect for the prime minister and the job she's doing. and the prime minister beamed. we had a great discussion today and we continue to have that really special relationship between the uk and united states, standing shoulder to shoulder, because we're facing the same challenges across the world, and we're working together to defeat those challenges. and downing street has confirmed that officials are finalising arrangements for a working visit to the uk by donald trump later this year, though no mention of the invitation for a state visit that theresa may extended a year ago. this evening, the president had dinner with european business leaders, some more important to mr trump personally than others.

the makers of aspirin. i think you take it? i do. i should say i only take one aspirin a day. so far, it's been working. his whole purpose of the trip to davos... ..to sell america. when i decided to come to davos, i did not think in terms of leaders, i think in terms of lots of people who want to invest, lots of money, and they're all coming back to the united states, they're coming back to america, and i thought of it much more in those terms. tomorrow comes the president's keynote address. the protectionist among the free traders, the america first president amid the globalists. it might not be a meeting of minds. but say it quietly, donald trump seems to be enjoying himself. jon sopel, bbc news, davos. philip hammond said trade relations

with the eu after brexit would be very modest. jacob rees—mogg has denied calls for a fundamental change in the tone of ministers on brexit, saying they were cowed by the you. we set out a good basis for brexit. that should be what is implemented. there are some concerns about the eu's demands about the transition period. it is important to make clear at this stage we will not roll over and accept what the eu is asking for. there's been a sharp rise in the number of serious violent crimes and sex offences recorded by police in england and wales. but a separate survey based

on people's experiences rather than official data recorded by police suggests that overall crime is continuing to fall. our home affairs correspondent, tom symonds, reports. behind the statistics, wasted lives. a decade after meschak cornelio first tried out the bike he'd been given as a present, he became one of the four young men stabbed to death in london on new year's eve. leaving his father confronting a nightmare. the doctor said to me, mr cornelio, sorry about it, about meschak. when he came here... not at least one hour, he said a couple of minutes, he is dead. so he came into hospital and within a couple of minutes, he was dead? yeah. he tells us in his native portuguese he has no idea why it happened, what might have been going on in meschak‘s life. translation: my advice for other parents would be to talk more to your kids. try to find out, even if you think they have secrets away from home. today's figures set out the rise

in violent crime recorded by police. knife crime went up by 21%. gun crime, up by 20%. manslaughter and murder went up by io%. now the official survey of crime shows the number of people who say they have been a victim is falling steadily, but police records are seen as an accurate measure of serious violent crime. and despite schemes like these bins, where knives can be handed in no questions asked, it is rising steadily. he said, "i didn't mean to kill him, that wasn't my intention." "i just wanted to wet him up, slash him, cut him across the arm, take photos and upload it onto social media." this is alison cope, and she is talking about the murder of her own son. her audience, students at coventry college. 2012... josh ribera was better known as the grime artist,

depzman, to his thousands of fans. a single slash of a knife took his life in 2013. his eyes flicker, they close, hits the floor. it's a tough listen. alison tells them these are the consequences, but carrying a knife is your choice. she believes telling them not to doesn't work, and says that's how the government's current policy comes across. they are standing up and doing their token gesture. and it isn't working. how many young people have to die for them to admit that what we're doing is not correct? true, government policy recently has centred on enforcement. tough rules on knives, tough policing, tough sentences. but today, ministers appeared to signal a change towards alison's way. we have to get to the root causes, and we have to work as a society, government, police, and civil society, to try and get to the root of this cultural issue and try and steer young people

away from violence. but serious proposals for work with young people are not going to come cheap. and by the way, police numbers are now at their lowest level for two decades. tom symonds, bbc news, in the west midlands. lord mandelson has been sacked for attending the presidents club dinner. jeremy corbyn asked him to step down following reports of sexual harassment and groping. he said he did not see any of the alleged behaviour which he called appalling. now on bbc news, in a special debate, we ask can a free and fair media operate in a digitised world and restore trust in political debate? from the world economic forum in davos, here's zeinab badawi. the swiss resort of davos, where

movers and shakers of politics and culture gather annually at the world economic forum. the topic in this debate is fake news and the challenges and threats it presents the politics and society is. from influencing voters to fostering prejudice, there are growing calls for something to be done. on line giants like google and facebook say they are trying to prevent fake news spreading on their websites, but is it too late to stop the rot? welcome to the world economic forum in davos, where the debate starts on fa ke davos, where the debate starts on fake news. it is one of the buzzwords of our time. it is a significant phenomenon of the

internet age. jimmy wales, co—founder of wikipedia, on a mission to fight fake news with the launch of wikitribune. the managing editor of the new york times. it was founded in 1851 and has received more than 120 pulitzer prizes. the deputy editor in chief of rt, a kremlin backed network. and the chairman of the pakistan people's party. the son of the former prime minister. welcome to the panel. to you watching and listening around the world, welcome, whether tv, radio, or on the web. now, first, i asked our colleagues on the bbc‘s technology programme, click, to look at what fake news is and how it is

becoming more and more sophisticated. the fake news. fake news. this is fake news. a little bit of fake news. fake news. you are fa ke bit of fake news. fake news. you are fake news. fake news. everyone is using the term these days. and with good reason. president trump may have helped put the term in the dictionary, the rest of the world has been struggling to separate fact from fiction. that was fake. the headline was this is how islamic society looks like, and we are heading... that was fake. the most grotesque stomach chilling videos. that was fake as well. it seems to be everything from actual lives to something you do not agree with. so, just how do we sort fact from fiction? opinion from satire. and

highly skewed and misleading headlines? tech giants like twitter, facebook, and google, have spent a year dealing with the problem. but ina year dealing with the problem. but in a world of likes, clicks, and attention, do they have what it ta kes to attention, do they have what it takes to fight the fakes? one of the reasons it is so hard to fight is there is big money to be made creating its. for the first few yea rs i creating its. for the first few years i was so much younger. it is written by regular people sitting down on computers that have learned a formula, a scandalous title and false information, and that means profit. even a 13—year—old can do this. one thing is certain, fake news is a lot easier to make and share than it is to find and debunk. and recognising fake news could be about to get even harder. new technology can soon make us question not just what we read,

technology can soon make us question notjust what we read, but everything we see and hear. you cannot get charged more... from stealing our faces to cannot get charged more... from stealing ourfaces to mimicking our voices. i am not a robot. what is real has never been so unclear. fact checking organisations and technology is working to identify and flag fake news. researchers are investigating the impact. and we are all becoming more aware of the power it can have. russia is seeking to weaponise information, deploying its state—run media organisations to climb fake stories and photoshopped images in an attempt to sow discord in the west and undermine institutions. is it too little, too late, or is this just the start of a high—tech fake news battle? quick question to all of you. how

useful a term as fake news? joel? did you make it is a useful term in the sense that your clip points out. the phenomenon of maliciously created, false information for economic or clinical purposes is an ongoing and serious threat. when used in information is distributed so widely. is it a useful term for you? are not so sure. feelthat misinformation, propaganda, disinformation, these have been long—standing components of information warfare. fake news has re ce ntly information warfare. fake news has recently gained prominence, vis—a—vis the american election. as you
