there's no evidence say experts of it being harmful. but sleep, exercise, and family time must come first they say — and no screens an hour before bed. i take everything away at bed time. i take laptops, tablets, phones, awayjust because there's no kind of distraction. but some parents and campaigners are frustrated by the advice, and say there should be more support. also tonight — a man is stabbed to death in front of horrified passengers on board a train in surrey. this is the scene at horsley station now — police are searching for a murder suspect in the surrounding area. the arrest of a british national in russia for spying — the foreign secretary tells moscow — don't use him as a diplomatic pawn. a washout on thailand's tourist islands, as the worst storm in 30 years hits the region. and spreading their luck — the winners of the £115 million euromillions jackpot — who will share some their cash with 50 friends.

i want a bungalow because i can't walk up stairs. it might be a bigger bungalow than we were planning to have. but there's no way i'm joining thejetset. and coming up on bbc news — the magic of the fa cup is back — it's third round weekend. tranmere get the first of 32 ties under way against tottenham tonight. good evening. new guidance on children's use of screens recommends that parents should set time limits, and a ban before bedtime. but it says there's little evidence that using devices

is in itself harmful. the report by the royal college of paediatrics & child health says parents should worry less about screen time being "toxic" to health. but it has drawn up a check list to help parentsjudge if their children are using screens in a healthy way. some have criticised the research, saying the advice doesn't go far enough. here's our medical correspondent, fergus walsh. how much screen time via smartphones, computers or tv is ok for kids? these children from beckenham in south london have strict limits set by their mum, including no screens before bedtime. i think that's really fine because i play on it. i always play on it, really. i have a computer upstairs and that's where i do a lot of my homework on. but, like, in my free time when i'm not doing, like, homework and training it's calm tojust chill on my phone. if i think back too when i was younger, i think

the thing for us was tv. you know, we were on tv too much, we watched tv. what was it going two do too us? i think it'sjust a new medium. i think tablets a new medium, it's this generation and this is how they spend their time. i don't think it's bad. nothing is bad in moderation. today's guidance says as long as children are active and healthy then parents are best placed to decide what screen uses appropriate and there's no need for a set time limits. there's not good enough evidence for a particular threshold and it's really difficult two pick a number here. the second is actually applying a threshold is very difficult. what about homework? what about educational things? what about piano practice with your music on an ipad? it's very difficult two actually put these things in practice. and often what happens is itjust makes people feel bad about what are quite normal activities. many studies have shown an association between high screen use and obesity and depression. but the royal college says there's simply not enough evidence too show a direct causal link. it might be that children with those issues are more likely to use screens excessively. in its guidance, the royal college recommends families ask themselves four questions. is screen time in your household controlled?

does it interfere with what your family wants to do? does it interfere with sleep? and are you able took control snacking during screen time? the child health experts say there is a need for better research, especially on the effects of social media. so this guidance could change in years to come. one thing they are sure of is that children should not use screens in the hour before bedtime because the light can slow the release of the sleep inducing hormone melatonin. fergus is with me now. the research says there's little evidence screen time is harmful, but is that really going to reassure worried parents? every pa rent every parent will have struggled two ta ke every parent will have struggled two take away an iphone, ipad, orany kind of computer screen from a child. they will all have a view on

this and some will really be disappointed that the royal college of paediatricians hasn't recommended time limits. in canada, for example, paediatricians recommend no more than one hour of screen time for 2—5 —year—olds but you can be sure if they have recommended time limits here they would be accused of nannying. what the royal college has done is said we should take a common—sense approach and we shouldn't demonise screen use in itself. the trouble is that technology is developing fast. most of the research in this area was looking at television screen use, time in front of a tv, and that's a very different. two hours in front ofa tv is very different. two hours in front of a tv is very different from two hours on social media. we need more research here. screens are a way of life for the young so individual pa rents life for the young so individual parents needs a look at what impact it is having on their children's development. fergus, thank you. a man has been stabbed to death in front of passengers on board a train in surrey. a search is now under way for the murder suspect who got off the train in the clandon area.

our correspondent richard galpin is at horsley station where the train came to a stop. richard. yes, a major police investigation continues this evening with the police trying two identify the man who carried out this brutal attack. and, of course, trying two find him. throughout the afternoon police have been searching an area just a few miles from guildford two try and find the murderer who carried out this brutal attack. forensics teams have also been searching the train itself were a man thought a bee in his 50s was stabbed two death in what the bbc understands was a vicious fight. the men had boarded the train at london road station in guildford just after 1pm this afternoon. a few minutes later at clandon, the next stop on the line through waterloo, the murderer is believed too have got off and fled. the train went on two horsley

station where ambulance crews found the victim dead. in a statement detective superintendent gary richardson of british transport police said this was a shocking and violent attack which took place on board a train in broad daylight. he went board a train in broad daylight. he we nt o nto board a train in broad daylight. he went onto say that we know this was an incredibly frightening incident for passengers travelling on the train. as the police continue their investigation this evening, the man who carried out this fatal stabbing is still on the run. the police are appealing for any eyewitnesses do come forward as quickly as they can and do contact the british transport police. richard galpin, thank you. police say there's evidence that members of criminal gangs are deliberately getting jobs in prisons to bring in drugs. the warning comes after leeds prison introduced an x—ray body scanner to detect illegal substances. but prisoners are finding new ways for them to be smuggled in, including being given clothes soaked in drugs — so they can cut

the material up and smoke it. our home affairs correspondent, danny shaw, reports. stand up on to the two black marks. that's it. spin around and face me. just place one hand on to that. using x—ray technology to make prisons safer. this is a demonstration of the first body scanner to be installed as part of a government programme to reduce drugs and violence in ten of the worst affected prisons in england. nearly finished. it is used on prisoners if there is intelligence they've hidden a package inside them. this is an image of an inmate found with concealed drugs on the first day the device was deployed. you can see the straight edges, which shouldn't be in the human body. the scanner operates in a similar way to a standard hospital x—ray machine, but the level of radiation is 400 times lower. that is a photograph of a normal—sized felt tip pen,

that is a mobile phone alongside it, which is about the size of your thumb. this phone was smuggled into the jail, prisoners use mobiles to order drugs. there is no limit to the techniques they come up with to get drugs in. they've been soaking clothes in drugs, and then either smoking bits of cutup clothing or then using kettles, boiling drugs out and impregnating them back into paper. the prison market for drugs is highly lucrative. 0ne inmate, locked up for armed robbery, told me when prisoners get into debt, but he wasn't involved himself. lads are getting themselves into debt, can't pay their debt,

they get beaten up for it. get yourself into drugs, buying drugs all the time, you can't pay, and the other lads can beat you up to show that if you don't pay that is what is going to happen. leeds is one of ten prisons where the government has promised to reduce drug—related violence by this summer, assaults have been rising since 2014, and were projected to increase in eight of the jails last year, though the final figures have not yet been compiled. a lot more availability, a lot more access to them. at the st george's crypt centre in leeds, i asked former prisoners if they thought the government plans would work. if they want to solve the problem, they need to work with the social issues, the problems that are making people want to use substances in the first place. the drugs trade is controlled by organised crime groups, and now there is evidence some criminals are deliberately getting jobs in prisons to bring contraband in. the government minister who staked his political career on the prison reforms admits this type of corruption is a problem. it can happen, and the answer to that is searching, searching notjust in terms of finding a bad apple but also, if you have very good search procedures in place, it's much more difficult for a prisoner to put pressure

on a prison officer. at leeds they've blocked off windows to stop drugs getting in. packages were dropped by drones or thrown over walls. the new scanner will help, too, but there's a long way to go. a child killer, who was released from prison in 2002, has been sentenced to life for the attempted murder of a woman in peterborough. stephen chafer, who's now known as stephen leonard, will serve at least 17 years for attacking the woman last year after a row about a garden rake. he sexually assaulted and killed three—year—old lorraine holt in derby in 1979. the foreign secretary, jeremy hunt, has said that russia mustn't use british citizens as "pawns in diplomatic chess", after the arrest in moscow of a joint us—uk national on suspicion of spying. paul whelan's family say he was simply attending a wedding. british diplomats are asking for access to mr whelan in moscow. here's our correspondent sarah rainsford.

this is paul whelan. just charged in russia as a suspected spy. a former us marine, the 48—year—old is also a british citizen. he arrived in moscowjust before christmas for a friend's wedding. the guests were staying at this prestigious hotel. 0n the day of his arrest he had been showing them round the kremlin just metres from here. his twin lives in canada where the two brothers were born to british parents. it's very hard for me to understand how anyone would consider paul to be someone who would be a lawbreaker and take those sorts of risks, particularly in countries where they are less maybe flexible about lawbreaking. paul whelan has run this russian social media page for over a decade. he last checked in on the day he was detained. some friends have military connections like him. this post congratulates them on defenders of the fatherland day. but all those we have spoken to say his behaviour

was never suspicious. mr whelan's lawyer says he is now in solitary confinement in this former kgb prison. ever since paul whelan was detained and brought here, russian officials have given very few details of what he is actually accused of. the fsb security service his implied only that he was caught red—handed carrying out what it called spying activities. 0utside russia is increasing speculation that this arrest is part of a far bigger political game. one theory links his fate with that of this woman. last month maria butina admitted to conspiring to act as an agent of influence in america for the russian government. president putin is among those protesting her innocence. so is russia trying to negotiate a swap? for now the british government is ruling nothing out. we need to see what these charges are against him, understand whether there is a case or not. we are giving every support

that we can but we do not agree with individuals being used in diplomatic chess games. this arrest is bound to cool relations between russia and the west even further. the charge of espionage against mr whelan carries a possible sentence of up to 20 years. the time is 6:14pm. our top story this evening: parents are told to worry less about children's screen time, as experts say there's no evidence of it being harmful. and, are you on their list? the euromillions winners who've pledged to share part of their £115 million win with 50 friends. coming up on sportsday on bbc news — who's title is it now? manchester city beat liverpool to throw the title race wide open, with liverpool's lead now down to four points after an impressive victory for the champions. it's the start of a new year,

the weather is cold, and many of us are back at work after the break. invariably this is the time we start trying to plan a holiday in the sun. this, though, is a year with a big difference, with the uk due to leave the european union on march 29th. so what impact is brexit likely to have if you want to book a holiday abroad? 0ur consumer affairs correspondent colletta smith has been finding out. back home and back to work after christmas. this is the moment people's thoughts turn to the next getaway, but this year is going to be different. it is a worry that flights will become too expensive, you know? do try to come home and see family and stuff three or four times a year and if that gets too expensive it is a bit of a worry. i think people will be worried about whether they are going to need a visa but that doesn't stop them travelling to other

parts of the world. i don't know about brexit in honesty. does anybody understand brexit? because i definitely don't. the government say passengers can book their trips with confidence and the european union have confirmed even if there is no deal we will not need a visa to travel to europe. one of the biggest brexit impacts on holidays, whether or not there is a deal reached, will be on the price of them. the pound has bounced around loads over the last couple of months on brexit news and that makes it really hard to plan in advance, to plan ahead exactly how much value you're going to get for the pound when you get on holiday. 0ne impact could be on flights. they are likely to increase in price because most airlines buy fuel in dollars. my advice to customers would be to wait until they are ready to buy, just before they go away, and check the rate then.

i cannot see it being any great increases in the rates like they used to be. so if you are going on holiday this summer it's about holding your nerve, then? yes, unless they have to go away immediately and you need your currency, then of course you need to purchase it. 0therwise if you are not going until the summer i would wait. the easter break is just a few weeks after the brexit deadline and if there is no deal you will need at least six months left on your passport to travel to europe. you may need an international driving permit to hire a car. for now it is political details and asked out on the ground in westminster that will decide. well, on the ground in westminster, theresa may will be trying to persuade mps to back her brexit agreement later this month. let's talk now to our political correspondent, chris mason. mps are back in the commons next week. has anything changed over the winter break? if you needed any further proof that

fun is cancelled, that christmas is over, at the trundle back to work is on, the pause button on brexit chat in the news is being lifted and that all—consuming noise before christmas is going to resume. but has anything changed? is going to resume. but has anything changed ? the short is going to resume. but has anything changed? the short answer is no. the democratic unionist party which props democratic unionist party which pi’ops up democratic unionist party which props up theresa may in government did not like the withdrawal agreement before christmas and guess what? they still do not like it and neither do a lot of conservative mps. they do not like the so—called backstop, the insurance policy to ensure that the border between northern ireland and the republic remains open. the prime minister has made telephone calls over christmas but she does not seem to have secured enough from them to secure enough people here to change their minds. still it looks as if she will

lose this big fault macs coming up inafew lose this big fault macs coming up in a few weeks. mps return on monday and they will start debating the withdrawal agreement in the week and we expect the votes to be a week on tuesday. brexit is due to happen 12 weeks tonight. thank you. let's take a look at some of today's other news. an mp who was found guilty of lying to avoid a speeding fine, and could face a prison sentence, has been expelled from the labour party. fiona 0nasanya won peterborough byjust a few hundred votes at the 2017 election. she's indicated that she won't resign as an mp. house prices last month rose at their slowest annual rate since february 2013, according to the nationwide building society. the average home was worth £212,000, 0.5% more than the year before. the lender says uncertainty over the economic outlook appears to be undermining confidence. congressional leaders

in the us have been meeting with president donald trump in an attempt to end a partial government shutdown. mr trump has said he'll reject any new budget that doesn't provide funding for his proposed us—mexico border wall. the democrats have refused that funding so far, with new house speaker nancy pelosi calling the wall immoral. thousands of people in southern thailand are fleeing the path of the worst tropical storm to hit the area in 30 years. storm pabuk made landfall in the early hours of the morning local time, sending trees crashing into houses. thousands of people have left the islands of koh samui and koh phangan. the storm is now moving across the south of the country, affecting popular tourist spots. over one million british tourists visit thailand each year. our world affairs editor, john simpson, reports from the north of koh samui island. his report contains flashing images. this was just the start of it.

super storm pabuk, meaning giant catfish, is, in the words of thailand's meteorological head, simply huge. it hit the two northerly islands hard early on in the day. by noon it was starting to close down the island of koh samui as well. the roads were empty of traffic and winds of 50 mph or more were blowing down trees close to the sea. the emergency services were out in force though in the hours of daylight the number of injuries was still quite small and only two deaths had been reported. yesterday, thousands of visitors, thai as well as foreign, tried to get off the islands while they still could. but some stayed, either because they couldn't leave or perhaps because they wanted to see what was going to happen. sam and miranda from cheshire came to koh samui to celebrate his 30th birthday.

we were able to get out and stock up pretty quickly so we filled the room full of food and got as much protective mattresses taped to the windows, doing whatever we can to keep the room safe. and reallyjust riding it out. to be honest, no one really knows what's going to be happening here in the next few hours. the weather seems to be changing all the time. the rain, which was drenching just a few minutes ago, has suddenly stopped but the wind has come up pretty fiercely. tonight the storm proper is just about to hit koh samui. what is certain is that this super storm is highly unusual for this time of year. france is increasing security along its northern coast, around calais, after a recent rise in migrants attempting to cross the channel in small boats. the british government

has also announced that a navy patrol vessel, the hms mersey, will monitor the waters until two border force cutters currently working abroad can arrive in the channel. now what a great way to start the new year, matching seven numbers and finding yourself nearly £115 million richer! that's what happened to frances and patrick connolly, from county down in northern ireland, who say they've drawn up a list of 50 people whom they intend to share their euromillions win with. here's chris page, there are some flashing images in his report. it's the time of year when lifestyle changes do happen. but they are very rarely as dramatic or unexpected as this. on new year's day frances connelly was knitting a jumper at home when her husband patrick looked up the lotto results online.

checked my numbers and they all were ticked and i thought, does that mean we have won? i went on the bbc website, i checked the numbers there, again a match. i then went on a third website and i checked again and they matched, so i turned the computer to frances and i said, i think i've got some good news for you. and i said some things i shouldn't have said and accused him of lying to me and he said no, i wouldn't make a joke about something like that. he was shaking by this stage. welcome to tonight's special euromillions draw. francis and patrick were not dreaming. this machine had bestowed sudden and sumptuous wealth on the couple from the village of moira. it is the fourth biggest lottery prize ever won in the uk. how different do you think life will feel like for you? we are fairly well grounded. we are notjoining thejet set life, you know? we want to help people, share the money, and when we've had

a bit of fun and had a bit of travel we'll come back and we'll do some good. but at the news conference one reporter asked if they had new worries about personal security. i've never met anybody i wouldn't take down myself, to be fair. they have become fabulously rich in just a few seconds but what the connellys are most looking forward to is giving away money and making some more millionaires. time for a look at the weather. here's darren bett. it was pretty chilly this morning. any time you have high pressure at this time of year you break the cloud and that brings frost. the temperatures did not rise even though there was some sunshine. we

saw the two faces of the weather across the uk under the high pressure. some places enjoyed lots of sunshine but it was still cold. it was certainly called in the bury we re we it was certainly called in the bury were we had a lot of cloud through the day. no sign of that moving across this part of the uk. clear skies down here and this is where temperatures are falling quickly. the cloud will be thinner down the eastern side of the uk. it is then sold temperatures will not be far from freezing. longer clear spells towards the west country. the best of the sunshine coming in the afternoon for eastern scotland, north—east england. 0n the whole most of us will be cloud you tomorrow but dry. temperatures struggling. we will see a bit of rain into the north—west during the evening which fades away as we get to sunday. that introduces cleaner

air. for most of england and wales a fair bit of cloud with sunshine if you are lucky. if anything temperatures should be higher on sunday. light winds this weekend. that changes as we head into next week when high pressure gets pushed towards the south, a low—pressure moving in, severe gales in northern scotla nd moving in, severe gales in northern scotland developing later in the day. continuing overnight and probably into tuesday as well. by tuesday the wind direction has changed. more of a north to north—westerly wind which could bring sunshine but also wintry showers. it will feel colder in the wind but probably only briefly as the wind ez wind but probably only briefly as the wind e2 is down on wednesday. a reminder of our top story. parents are told to worry less about children's screentime as experts say there's no evidence of it being harmful, but there

should be a ban before bed. that's all from the bbc news at six, so it's goodbye from me, and on bbc one we nowjoin the bbc‘s news teams where you are. hello, this is bbc news with lu kwesa burak. the headlines. a murder investigation is under way following a fatal stabbing on a train in surrey. police describe a "shocking and violent attack", as they search for the suspect. police describe a shocking and violent attack, which took place onboard the train in broad daylight. experts say parents are the best judge of how long their children should spend on smartphones and other devices, but do recommend n0 screens for one hour before bed. the foreign secretary, jeremy hunt, warns russia not to use uk citizens as "diplomatic pawns", after a british national is held on suspicion of spying. police say there's evidence members of organised criminal gangs

are seeking prisonjobs in order to smuggle in drugs. cheering the couple who hit the jackpot. they plan to share their good fortune — after winning the £115 million prize. in a moment it will be time for sportsday, but first a look at what else is coming up this evening on bbc news. at 7:00, we'll be live in horsley for the latest developments as a manhunt gets under way for the suspect who fled the scene after a vicious fight. at 7:10, we'll hear from a foreign policy analyst about the implications of the dual american and british national detained on espionage charges in moscow. and coming up later this evening, we'll take a first look at tomorrow's front pages in the papers with my guests.
