break a 14—year—old club transfer record to sign the biggest deal of deadline day so far. good evening and welcome to the bbc news at six. there's been a big increase in the number of young people contacting a suicide prevention charity helpline since we highlighted the case of 14—year—old molly russell last week. she took her own life just over a year ago. herfather blames her death partly on images of self—harm and suicide that she saw on instagram. molly's story prompted a huge response, with many families getting in touch to share similar experiences and concerns.

facebook, the owner of instagram, has said it's "deeply sorry" about her death and mps have been calling for social media companies to take more control over their content. but will anything actually change? our reporter angus crawford has spoken to some of the families who got in touch with us. i must warn you, his report is upsetting and contains some images you may find distressing. she had so much to offer. molly russell's story... and that's gone. ..has sparked a debate... these are companies that count their profits in the billions, and they turn round and say to us that they can't protect our children? ..that may change social media for good. do you have the power to compel them to do what needs to be done? yes, absolutely. and it's also struck a chord with families across the country. like ian and his daughter libby, so horrified by what happened to molly that they've decided to speak out. libby once had 8,000 followers on instagram. 16 and now firmly in recovery, libby used to self—harm, an obsession learned on and fed

by the platform. i don't think it made me do it, but i think it definitely accelerated the severity of it, because i'd see people and then and then you'd almost go, "that's ok, then, it doesn't matter how bad it gets because they're not dead, it hasn't killed them doing that". so it kind of made it feel more safe to do it worse. her dad tried to get the worst content taken down, but says it was a waste of time. you go, "right, i'll try and get rid of this account, there must be a way to stop it", and there's nothing. and they're not interested. and until one of their close family members. and until one of their close family members falls down that rabbit hole, they won't do anything about it. until it affects them or their wallet, they are not interested. meet chloe, who's i2, and her mum emma. shocked by molly's story,

they rang the bbc. chloe had stumbled across just this kind of content. platforms on social media could, like, kind of stop a report or take down bad things on the internet that are scaring people, because i know it's just notjust me who's getting scared by it. i know there must be other people. users should be at least 13 to be allowed on instagram, but emma says age restrictions aren't the point. the reality is that people are using them at that age, so whether there's the age limit... and when she's 13, what difference is there going to be? molly was 14. does that mean it's acceptable for her to see those images? i don't think there's any age that's acceptable. a hard—hitting video with a simple message, encouraging young people to talk about suicide. molly's death has certainly done that. there's been a 40% rise in calls

to this charity's helpline. this is james murray. his son ben took his own life last year, aged 19. a technology consultant, james knows social media can change. do you think the penny is dropping? the penny‘s dropping. i think molly's case could be a turning point. what they should be doing when somebody is looking at self—harm or suicide is promoting positive content over and above the negative content. so the algorithm could be used for good? yeah, absolutely, and it's high time the social media companies delivered on the promise of social value and became a force for good in the community. instagram says: molly's story has touched a raw nerve and sparked a demand for change.

the social media companies now have to decide if they will embrace reform or have it forced upon them. and angus is here now. do you think molly russell's story could prove to be a turning point?|j think we may be inching towards real change. i say inching because in the past the government has talked big and delivered little on this. in effect, they have been shouting at the tech companies to stop, but i detect a more strident tone emerging from ministers, even talk of laws imposing a duty of care on them. how have instagram and facebook responded? they have instagram and facebook responded ? they have have instagram and facebook responded? they have been dragged before the cameras twice in the last ten days by our media editor amongst others, and they have promised change, a formal review of all their policies. they also said they will blur images of self—harm. but even that begs the question, if they know where the images of self—harm are, why not just take

where the images of self—harm are, why notjust take them down? and what about parents? as you see, huge reaction. many have got in touch. but several told me in private in the last few days that they have spent hours reporting what they saw as bad content, graphic images and self—harm accounts on instagram, only to be told no action would be taken because they didn't breach community standards. so it seems there is still a very long way to go. angus, thank you. if you're distressed about any of the issues raised in this report and would like details of organisations which offer advice and support, go online to bbc.co.uk/actionline or you can call for free at any time to hear recorded information 0800 066 066. around 100 vehicles are currently stuck on the a30 — a major road through cornwall — as heavy snow begins to sweep in. emergency services say they're dealing with many calls across the county. the snow is expected to spread towards wales and southern england later tonight, with significant travel

disruption expected. jon kay is in 0kehampton on the a30 for us. definitely snowing? definitely snowing, yes. the a30 is the big dual carriageway that goes through the middle of devon and cornwall over the moors. as you say, hundreds of people have had to abandon their vehicles not just of people have had to abandon their vehicles notjust on the main road, but we have seen people coming off the a30 onto the side roads in the last few minutes, leaving their cars and getting people with 4x4 is to pick them up instead. i have seen a bus coming off as well because it is so bus coming off as well because it is so thick and it came down so fast on pa rt so thick and it came down so fast on part of that main route. 0vernight the met office is predicting there could be up to ten centimetres of snow in some places. notjust on higher ground. it is going to be patchy where it falls, so stay tuned for the full weather forecast at the end of this bulletin. it's going to cause all kinds of problems notjust on the roads that we have already talked about, but on the railways as well and not just tonight, talked about, but on the railways as well and notjust tonight, because this could have a knock on into

tomorrow morning's rush hour. tonight is bad, tomorrow morning could be bad as well, so check your local radio and the bbc website for all that information. we have had low temperatures. it was my —14 celsius in aberdeenshire overnight. it might not be that cold tonight, but the snow is falling and there is a wind—chill in place, so we all have to be careful. this is not like the beast from the east last year. it's not that severe. this is more like the wet stuff from the west. but after a relatively mild winter so but after a relatively mild winter so far, this will cause a jolt for a lot of people and apparently quite a lot of people and apparently quite a lot of people and apparently quite a lot of disruption. jon kay, thank you. and spare a thought for parts of america's mid west. temperatures have already dropped to minus 30 celsius in chicago, with worse to come. at least 12 people have died since saturday as many states experienced their coldest winters for decades because of what's 0ur north america correspondent chris buckler is in chicago for us — how cold is it right now? at the moment it has warmed up a

little. it is now —20 celsius, but it feels much colder in the wind chill. truthfully, it is painfully cold. you really feel it. it's probably best if i show you how cold it is. we brought this t—shirt out of the hotel a couple of minutes ago. within 60 seconds, it was frozen completely solid. that gives you an idea of the conditions that people are facing here. chicago stands surrounded by ice and snow. people here are used to cold weather, but these are temperatures seen only once in a generation. the windy city has become the wind—chill city. my fingertips have been frozen twice, toes frozen twice. so i have made two stops. it's brutally cold. you can actually see frost on your eyelashes! what does it feel like?

it's a little cold. they have frozen closed a couple of times. across america's midwest, temperatures have dropped far below freezing. a huge pa rt dropped far below freezing. a huge part of the us court in what is known as a polar vortex. it's pushed arctic air down from the north pole and left many places colder than the antarctic. people have been doing their own small science experiments to see for themselves just how cold it is, including this. i have got boiling water in this flask, and you will see, as soon as i throw it into the cold air, it simply freezes. further north, some of niagara falls has frozen. in chicago, they have been using boats to try to break through the sheets of ice that cover the river here. rail tracks have also been set on fire just to keep some services running. this is a bitter cold that has already left some people dead. the frozen beauty

of these conditions shouldn't distract from their dangers. chris buckler, bbc news, chicago. there were more than 11,500 rough sleepers in england last year, according to government estimates. the overall number is slightly lower than the year before, but the number of people sleeping on the streets in london rose by 13%. homeless charities say that the estimates — which were collected on a single night — don't provide a full picture. everyone calls it a young man's game. it shouldn't be no one's game. sleeping bag. you don't really sleep, do you? you take cat naps. this is england in 2019. in a doorway of a shop selling thousand pound mattresses, ten rough sleepers seek rest. more than a600 people

sleep outside each night, 2% lower than last year, 165% higher than 2010. i was in and out of doorways before. my mate said, do you need a tent? when has been rough sleeping for five years, forced from home, tent? when has been rough sleeping forfive years, forced from home, he says, after his marriage collapsed. why don't you take up shelter? you end up being bullied or picked on, don't you? i would rather be outside, its safer. don't you? i would rather be outside, it's safer. it safer? 0therwise outside, it's safer. it safer? otherwise i would feel my own. in greater manchester city centre, they have seen more rough sleepers, but numbers have fallen in the wider region. this newly opened hostel is pa rt region. this newly opened hostel is part ofan region. this newly opened hostel is part of an initiative by mayor andy burnham to provide a bed for rough sleepers or winter. everyone says i have more lives than a family of cats, never mind one cap. the place has been a godsend to scott, who was rough sleeping while suffering from crohn's disease. i tried taking my

life numerous times. but try to keep that clean while being on the street and no one offering any help, i was just waiting to die. rough sleeping has worsened in several big cities. the overall full is due to large reductions in smaller towns, and ministers say, to the millions they are spending tackling the problem. we need to make rough sleeping a thing of the past. and whilst these figures today underline some progress, and it's important to note that, i know there is a lot more work to do. today's numbers are a snapshot, a mixture of counts and estimates for one night in november. both labour and homeless groups say the real problem is much bigger. but the real problem is much bigger. but the figures that really matter are resting and sleeping bags and doorways, and thousands of them need help tonight. michael buchanan, bbc

we ended up approving a deal in the days before the 29th of march, we might need some extra time to pass critical legislation. but if we can make progress sooner, that might not be necessary. passing laws, shuttling legislation between mps and peers in parliament takes time. a late deal would need time to turn it into law, no deal could mean a rush to pass legislation on immigration, health, fisheries and more ready for life up to brexit day on march the 29th. today labour's leader said any brexit the weight should be used to get a deal. the government has run down the clock and continues to run down the clock, it is possible they would have to be an extension or to get an agreement because we cannot leave the eu on the 29th of march without an agreement. brexiteers seem relaxed about a sword blade as long as it is stored. those who want a long delay we know that is about opening the doorto

top story... more pressure on social media companies to do more to protect young people from harmful images online. coming up... the inquest into the ira's guildford pub bombings is to be reopened after more than a0 years. coming up on sportsday on bbc news, england crumble in the caribbean again as the batsmen struggle on a tricky antigua pitch on day one of the second test against west indies. with less than two months to go until march 29th and brexit — the pressure is growing on businesses across the channel, as well as here. the uk imports almost a third of the food we eat from the eu. so, how will the fresh produce that ends up on our plate be affected by brexit? our business correspondent emma simpson has been to spain to find out. sunny southern spain, a sea of green houses. salad city, keeping us supplied with fresh produce. meet the team here.

they have been sending tomatoes to british supermarkets for more than 50 years. you can already smell how the tomatoes will be. this is the start of a long journey for these cherry tomatoes. we are growing about 60 million kilos per year of tomatoes. so it's quite a big amount. 60 million? yes. and a third of them end up on our dining tables. it's a well oiled machine, but how will this trade flow after brexit? the truth is that with no deal, we will have more costs to add to the chain. that could be at least another 10%, from extra staff to process customs forms to potential terrorists. —— to potential turrets. —— turrets. if all the costs are increasing, our margins are at their lowest point at

the moment so we cannot absorb any more into that chain. if we put anything else into it, this will not make a profitable business for us and we will have to decide to do something else. this perishable product is all picked and packed within 2a hours. it's now 5pm on monday and 20,000 kilos of tomatoes are now going onto this lorry on the clock is now ticking, because the supermarkets want them on the shelves by friday. a 2000 kilometre journey now lies ahead. he is heading for calais. before too long, he has hit the real winter weather. this spanish haulage company does hundreds of loads a week to the uk. we haven't been prepared enough. to handle the paperwork. it could mean delays. it could have a huge impact on the volume we transport to the uk. 0ur lorry‘s now at the eurotunnel border crossing, but it's having to stay the night. this place is soon to be the brexit front line.

we're ready. hard brexit, soft brexit, we've been preparing for two and a half years. we have ta ken we have taken the worst cases all the way through. can you guarantee everyone else will be ready? no. early this morning, our tomatoes reach england, bound for the shelves. 0ur journey stops at the supermarket distribution centre. the nature of our very efficient food supply chain is that there's very little surplus costs. the more inefficient it becomes, the harder it is to absorb that. costs will be passed onto consumers quickly. the story of this cherry tomato shows us just how reliant we are on the eu forfresh produce, especially at this time of year, and just how slick an operation it is to get it here. emma simpson, bbc news. footage showing the moment a three—year—old boy had sulphuric acid thrown over him in a shop has been shown to a jury in worcester crown court.

the child, who can't be named for legal reasons, suffered serious burns at a store in worcester in july last year. six men, including the boy's father, and one woman, are accused of plotting the attack. a coroner has ordered that the inquests into the deaths of five people in the guildford pub bombings should be, reopened more than a0 years after they were suspended. four soldiers and a civilian were killed in 197a when two ira bombs went off. four people accused of carrying out the attacks had their convictions quashed and were released after serving 15 years in jail. duncan kennedy reports. the horse and groom had been packed with soldiers and others. a second device went off in another pub. it was here where the deaths took place. five men and women were killed. their inquests were opened, but adjourned whilst the police investigated. that investigation here at what was the pub led to four people being jailed for life. the coroner at the time said

that as all the evidence was heard at their trial, there was now no need for a full inquest. but 15 years later, that evidence collapsed, and the guildford four were cleared. one of them, patrick armstrong, said today he was pleased a full inquest would now hear all the evidence. very, very happy. i am very emotional, very delighted for the families and the relations of the people that got killed in the bombs and were injured, because they deserve it. the coroner said today it was in the public interest to resume the inquest. lawyers say the families of those who died just want an untainted account of what happened. this is their opportunity for truth, justice and accountability, and also hopefully to allay the continuing rumours and suspicions surrounding the guildford pub bombings. the ira gang involved in the balcombe street siege said they carried out the guildford bombing, but no one was ever charged. the new inquest is due

to resume later this year, in the final attempt to unravel this prolonged tragedy. duncan kennedy, bbc news, in guildford. the queen has one of the greatest collections of leonardo da vinci s drawings in the world. to mark the 500th anniversary of the old master s death, she's sharing 1aa of his works with museums across the uk. 0ur arts editor will gompertz has been travelling around the country to see the drawings. leonardo da vinci was the ultimate renaissance man, a polymath who could turn his mind to anything and produce exquisite drawings, examples of which have been lent by the royal collection trust to 12 museums across the uk. each venue has a group of drawings selected to reflect the diversity of leonardo's interests. we are in the national museum in cardiff among its 12 leonardos, all of which are magnificent, of course, but i wanted to point out two of the works.

the first is this late anatomical drawing, which is great, but it does contain a mistake. in this left—hand edge leonardo has left an inky thumbprint. and then over here is a drawing which shows the artist's deep interest in botany. it's a beautiful symmetrical design of a grain bearing grass from asia. known asjob's tears. at the time it was very rare in the rest of the world. in fact, this is thought to be the first record of it in western europe. the drawingas on display here at the ulster museum in belfast give a sense of the extraordinary range of interests that leonardo da vinci had, from costume design to extreme weather effects. and of course, famously, his detailed analysis of the human body, with images which are still well regarded today. but are they accurate? they certainly are, will. if you look at the level of the anatomical detail here, it is equal to any standard surgical text in the modern era. more importantly, he's somehow picked up the functionality of these muscles and imbued them with life. the display here at the kelvingrove art gallery and museum

in glasgow shows the two sides of leonardo. 0n the one hand, you have the fine artist who is interested in modelling form in delicate detail using light and shade. 0n the other hand, you've got leonardo the engineer, who is interested in the movement of a horse and in designing weapons or fanciful war machines, as he called them. and he also liked to make maps such as this one of the central region of italy, including the arno valley where he was born. these, he made to support his architectural work. the final venue on this whistle—stop tour is the sunderland museum, where i am joined by carly collier from the royal collection. this is the image i really want to talk to you about. basically, it's an essay. absolutely. leonardo was an artist, a scientist, but also an intellectual, and here he is investigating the nature of light. obviously, there is some drawing because it's leonardo. in the great scheme of things, how good was he, from michelangelo to picasso? he really was a great draughtsman.

and he is very unique in the way he uses drawing to truly understand the world. ultimately, the subject of all these beautiful drawings is leonardo and the workings of his remarkable mind. will gompertz, bbc news, sunderland. a full weather forecast now with chris fawkes. how bad it was no going to get? it has been causing all kinds of problems across parts of south england and cornwall particularly, newquay airport closed for a time to get snow off the runway. this weather front has been working in some cold air. the rain has turned to snow notjust across south—west england, now central and southern england and across wales. the could be a few more issues. the met office have an amber weather warning stretching across south—west england towards hampshire and southern and parts of wales. some areas will see 5—10 centimetres of

snow. the risk of further transport disruption. the front will tend to wea ken disruption. the front will tend to weaken as it swings into south—east england and parts of the south midlands. the amount of snow we see across the south—east and midlands will become more variable. some places not seeing very much. 0thers could get a few centimetres and the risk of disruption. away from the snowy south, further north we have some wintry showers that will coming across the north—east of england overnight adding to an ice risk and also the north of scotland. for most it will turn a temperatures well below freezing, another very cold night particularly in the north. tomorrow morning any snow will tend to fizzle out across the south. a different wind direction in the north—east, some of those wintry showers, a bit of snow across north—east england towards yorkshire, localised accumulations possible in the hills, one or two centimetres. for most it is another cold and frosty and icy start to the date with the weather slowly
