an in—depth look at the papers with our reviewers, kevin schofield, editor of politics home, and dawn foster, columnist at the guardian. stay with us for that. police have this evening given details of the stabbing to death of a 51—year—old man on board a train in surrey. they said the killing happened in front of the man's 14—year—old son, and described it as a horrific and hugely traumatic event to witness. the perpetrator is not thought to have been known to the victim. a search is now underway for the murder suspect, who is described as black and in his 20s or 30s. the police are asking the public to contact them with any information

to help find him. our correspondent richard galpin is at horsley station, where the train came to a stop, and sent us this update. well, the police have been searching throughout the day for the men who carried out this horrific attack, but so far there has been no arrests. although the police do now have the description of a potential suspects, which has been provided by the local people here. forensics teams searching the carriage this afternoon in the wake of the murder on board the train heading from guildford to london. the victim — a 51—year—old man who died of multiple stab wounds, in what an eyewitness described as a vicious fight. his body was finally removed from the scene at horsley station this evening. the victim boarded the train

at around 1:00pm at london road station in guildford, along with his 14—year—old son. traumatically, the victim's son would have been nearby when his father was fatally wounded. this would have been an horrific and hugely traumatic event to have witnessed, and we're providing him with as much support as possible. the suspect is a black man in his 20s to 30s. he's approximately six feet tall, and of slim build, with a beard, believed to be dressed all in black, with white trainers. the train had left guildford at lunchtime, bound for waterloo station. the men boarded the train at the first stop, london road station, just after 1:00pm. a few minutes later, at clandon, the next stop on the line to waterloo, the murderer got off the train and fled. the train went on to horsley station, where ambulance crews found the victim dead. ever since then, the police have been searching for the man who carried out what seems to have

been a frenzied attack. but so far to no avail. although they say there have been multiple sightings of a potential suspect. it's really shocking, because around here, you don't hear things about that sort of situation happening. because it is a very quiet area. we are a close community around here, like, pretty much everyone knows everyone. no big news happens, so i think something that tragic is going to shock a lot of people. tonight, the people of this area know there is a murderer on the loose, following a highly unusual killing on a train in broad daylight. now, as you would expect, the police are calling on any eye witnesses to come forward as quickly as possible, evenif come forward as quickly as possible, even if they don't think they've got any useful information, and saying that those who do come forward should contact the british transport police. there are renewed tensions between britain and russia 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. the foreign secretary, jeremy hunt, has said moscow mustn't use british citizens as pawns in diplomatic chess. here is our correspondent sarah rainsford. paul whelan was with a wedding party staying at this top—end moscow hotel, but he never made it to the ceremony. he was arrested, charged as a spy. russia's security service implied he had been caught red—handed. as his family and friends insist he is innocent, the british government says it is extremely worried. individuals should not be used as pawns of diplomatic leverage, and you know, 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. so what do we know about paul whelan?

he was a reserve in the us marines for m years, and served two tours in iraq. in 2008 he was discharged for bad conduct — theft, according to military records. but it was from iraq that he made his first trip to russia in 2006. paul whelan has had a page on this russian social media site now for over a decade, and he has got dozens of friends on here. and, because this is a spy case, the ones i've contacted have been too nervous to go on camera to speak openly about him, but they have been messaging. and they have described a man who they say is very interested in russia and its culture, not in its secrets. in fact, one man told me, if paul whelan is a spy, then i'm michaeljackson. there are men on here who do have military connections, but even those men have told me that mr whelan never asked them anything suspicious. his twin brother says paul whelan had been showing wedding guests around the kremlin on the day of his arrest. 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're less, maybe, flexible about lawbreaking. he is now in solitary confinement in this former kgb prison. there is still no official word what exactly he is accused of. instead, there is speculation this could be part of a bigger political game, one that now involves britain as well as russia and america. so might vladimir putin himself be involved 7 last month, he condemned the detention of a russian woman in the united states. she is accused of trying to build back channels to republicans for her government ahead of the us elections. so might russia be banking on a prisoner swap? either way, this latest crisis threatens to cool russia's relations with the west even further. at its heart is a man facing a potential 20—year prison sentence for espionage. sarah rainsford, bbc news, moscow. police say there is 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 having their own clothes soaked in drugs so they can cut the material up and smoke it. our home affairs correspondent danny shaw reports. stand up onto the two black marks. that's it. spin round, face me. just place one hand onto there. 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 have 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 cut—up clothing, or then using the 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 what happens when prisoners get into

debt, though he wasn't involved himself. lads get themselves into debt, they 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 want to beat you up, to show that if you don't pay, that is what's 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 government minister responsible

has promised to resign if it doesn't improve this summer. he is concerned that people are deliberately getting jobs in presents to bring contraband in themselves. —— prisons. 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 have 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 is a long way to go. president trump says he is prepared for the partial shutdown of the us government, which is now entering its third week, to last years. he was speaking after meeting congressional leaders in the white house. mr trump has said he will reject any new budget that doesn't provide funding for his proposed

us—mexico border wall. but the democrats, who took control of the house of representatives yesterday, seem in no mood to provide the money. 0ur north america correspondent aleem maqbool sent this report. looking in, it might appear to be business as usual at the white house, but it is far from it. for two weeks, government has been shut down. the democrats won't agree to sign off on $5.6 billion for a wall along the border with mexico, and donald trump is refusing to back down on his demand that they do just that. the southern border is a dangerous, horrible disaster. we've done a greatjob, but you can't really do the kind ofjob we have to do unless you have a major, powerful barrier, and that's what we're going to have to have. while there is no agreement, 800,000 government workers are not getting paid, and many government departments and services

have been suspended. 0pposition leaders met donald trump today to try to resolve the crisis, but said they found a man who was uncompromising. so we told the president we needed the government open. he resisted. in fact, he said he'd keep the government closed for a very long period of time — months, or even years. but democrats themselves are not yielding. they have been emboldened after the swearing—in this week of new congressmen and women that now give them the majority in the house of representatives. among the freshman politicians who will be a thorn in the president's side was one of the first muslim congresswomen, rashida tlaib, always seen as someone representing a more combative, brash opposition. but few expected she would steal the headlines as she did, talking about the president at a washington reception. because we're going to go in there, we're going to impeach the bleep.

those comments provoked donald trump. using language like that, i thought that was a great dishonour to her and to herfamily. but what of that question of impeachment? well, you can't impeach somebody that's doing a greatjob. that's the way i view it. thank you very much. there is no question this week, though, that a resurgent democratic party has ushered in a new, more turbulent and divisive time here. aleem maqbool, bbc news, in washington. a fire has broken out at manchester's ivy restaurant. this video shows flames sweeping across the roof terrace as firefighters try to tackle the blaze. it is believed the fire in the three—storey building started from a patio heater on an outside terrace. the multimillion—pound restuara nt in the spinningfields area of the city centre opened in november. theresa may had a reportedly friendly phone call with the president of the european commission this afternoon on her brexit plans. it came as she prepares

to try to persuade mps to back her withdrawal deal later this month. the democratic unionist party, which has an agreement to support the government, has repeated its opposition to her proposals, saying there is not any way it can back them. 0ur political correspondent chris mason gave us this update. we are going to get a resumption of a rather noisy conversation, and as things stand, that conversation is rather familiar. white, to things stand, that conversation is ratherfamiliar. white, to answer your question, because little go at very little seems to have changed, so very little seems to have changed, so northern ireland's democratic unionist party prop up the prime minister and government. before christmas they didn't like the eu withdrawal agreement. guess what — they still don't like it now, and neither do a shed load of conservative mps. they still have real concerns about the so—called backstop, this insurance policy to ensure that the border between northern ireland and the republic stays open under any circumstances. so here is a sense of the timeline.

mps will return here on monday. they will be discussing and debating the withdrawal agreement by the middle of the week, and we expect the votes to ta ke of the week, and we expect the votes to take place a week on tuesday. but as things stand, it looks like the prime minister will lose. 0ne as things stand, it looks like the prime minister will lose. one final thought. 12 weeks tonight, we will be just 45 minutes away as things stand from the uk leaving the european union. the headlines on bbc news: a murder investigation and manhunt is under way after a man was fatally stabbed in front of his teenage son onboard a train in surrey. the foreign secretaryjeremy hunt warns russia not to use uk citizens as "diplomatic pawns" after a british national is held on suspicion of spying. new guidance says there is little evidence to suggest screentime is harmful to children — and parents are the bestjudge of how long they should spend on smart phones and other devices. let us stay with that story.

new guidance on children's use of screens recommends that parents set time limits, and a one—hour 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 and child health says parents should worry less about screentime — but it has drawn up a checklist to help them judge if their children are using screens in a healthy way. 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 to just chill out on my phone. if i think back to 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 to do to us? i think it'sjust a new medium. i think tablets is a new medium, it's a new 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 use is appropriate and there's no need for set time limits. there's not good enough evidence for a particular threshold and it's really difficult to 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 to 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 to 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 to 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 walsh, bbc news. 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. it hit the two northerly islands hard early on in the date, by noon it was starting to close down the island of koh stambouli as well. the roads were empty of traffic

and winds of 50 miles an hour were blowing down trees close to the seat. 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 have been reported. yesterday thousands of visitors thai, as well as foreign tried to get off the island while we still could. but some stated, i do because they could not leave, or perhaps because they wanted to see what was going to happen. sam and miranda from chester came to celebrate his 30th birthday. we were able to get out and stuck up pretty quickly,

so he filled the room with food and got mattresses and its windows and do everything we can to keep the room safe and reallyjust writing 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 though, the storm proper is just about to hit. what is certain is that this super storm is highly unusualfor this time of year. 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.

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. in india, police say a third woman has defied traditionalists and entered a hindu temple in the southern state of kerala, after two others set foot inside on wednesday. the sabarimala shrine has become the focus of a prolonged showdown, after india's supreme court overturned a ban in september on women of menstruating age entering the temple. the issue has triggered violent clashes in the state. yogita limaye reports from mumbai. earlier this week, these

women made history. escorted by policemen in plain—clothes, they were the first to enter the sabarimala temple since the supreme court allowed in september last year. now they've been kept in a safe house by the government because their lives are under threat. bindu ammini explains why she entered the temple. the things that happened in sabarimala are a violation of equality, and i like to establish order and implement judgement given by the supreme court. the implementation of this judgement also helps to implement gender justice in our society. their entry prompted fierce protests around the state of kerala. violent clashes broke out, and one person was killed. demonstrations were also held in the national capital, delhi. a black day, yesterday.

we never expected the government could do like this. the temple is devoted to a hindu god believed to be celibate. and so for decades, women between the ages of 10—50, considered impure because they menstruate, were not allowed inside. the issue has become politically contentious in the run—up to a national election later this year. the ruling bjp party, as well as the opposition congress, have both opposed the entry of women in the temple. kerala's local government has supported the court's verdict. on tuesday, they organised this human chain for gender equality, hundreds of kilometres long. translation: it's the state government's responsibility to give protection to women. and the government has fulfilled this constitutional responsibility. on thursday, a third

woman entered the shrine, and it's believed that more planning to do so. yogita limaye, bbc news, mumbai. personal data and documents from hundreds of german politicians and public figures, including the chancellor angela merkel, have been published online. hackers posted data including credit card details and mobile phone numbers from a twitter account. politicians from all major parties have been affected apart from the right—wing alternative for germany. a government spokeswoman said that no sensitive material from angela merkel‘s office had been released. 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 — and 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 the jet 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. and we'll be taking an in—depth look at the papers with our reviewers kevin schofield, editor of politicshome and dawn foster, columnist at the guardian. that's coming up after the headlines at 11:30. now it's time for the weather. hello. friday brought us mixed fortu nes hello. friday brought us mixed fortunes in the sunshine stakes for some. blue skies overhead. for others a loss of power. this weekend cloud tends to wind out. it will often tend to be cloudy but largely dry. we are being protected at the moment babyjet dry. we are being protected at the moment baby jet stream. dry. we are being protected at the moment babyjet stream. the jet strea m moment babyjet stream. the jet stream which drives weather systems in our direction is currently travelling a long way north of the british isles. essentially trapping

an area of high pressure right across the top of the uk. that is keeping things are settled. it is trapping a loss of cloud underneath it and these big areas of cloud will continue to circulate throughout saturday. will be some breaks in the clouds, chiefly across the west country for a time through the morning, then north—east scotland and england likely to see the lion share of any sunshine. elsewhere it expect a pretty cloudy saturday afternoon and those temperatures well down in single digits. a change in the north—west on saturday night, this band of cloud and patchy rain will sink across northern ireland and scotland, tending to fizzle, but feeding figallo cloud in across england and wales. not as cold as the last couple of nights. into sunday, we'll have the remnants of that weak frontal system, a band sunday, we'll have the remnants of that weakfrontal system, a band of
