good evening and welcome to the bbc news at six. borisjohnson has warned that the crisis over ukraine is probably at its most dangerous moment so far. as tens of thousands of russian troops take part in military exercises in belarus, close to ukraine's northern border, the prime minister, on a visit to nato headquarters in brussels, says intelligence assessments remain grim, but the west is pursuing a policy of strong deterrence and patient diplomacy. mrjohnson then travelled to poland, meeting some of the british troops recently deployed there. but issues back home have dogged his trip, with the former prime minister sirjohn major saying that attempts to excuse the breaking of lockdown rules in downing street are undermining trust in government and politics at home and abroad. our political editor laura kuenssberg is live in brussels for us this evening.

there is no question aboutjust how seriously the british government is taking the threat to ukraine. there is no question about how much all the countries who are part of this alliance, nato, based here in brussels, representing the west, want to avoid conflict. but there is nothing straightforward about trying to confront or handle a leader like vladimir putin. nothing straightforward about trying to contain the threat to europe's eastern fringe. boris johnson contain the threat to europe's eastern fringe. borisjohnson has been here and travelling to other european capitals but there are no easy answers at the end of this day of diplomacy. is the west walking towards a war on the edge of europe? as the russian leader dangles obvious danger to ukraine. good conversations, diplomacy and candour about the risk slow down a slide to conflict. the prime minister has promised the nato

abandon any thought ofjoining nato, even though everyone knows it's a very remote prospect anyway. and pressure perhaps even to bring the country crashing in on itself. but also pressure on the west, to have a dialogue about european security on russia's terms. and from vladimir putin's perspective, the prospect, the site of western leaders and officials beating a path to the kremlin must give him the belief he is onto something. the west, for all its firmness about nato's future, about ukraine's sovereignty and all the rest, has expressed a willingness to have a conversation about what is sometimes called the security architecture of europe. and essentially how nato and russia behave towards each other in the future. and i think president macron of france even said that would involve correcting some of the mistakes of the past. on those

drills in belarus that began today and are due to last ten days, what happens when they end? will the troops and equipment to go home or go somewhere else around ukraine's border? if they do leave the picture altogether, will that be seen, finally, as some small sign of a de—escalation? but again, think about it from the kremlin's perspective. why would you release the pressure on ukraine now when you appear to be the pressure on ukraine now when you appearto be gaining the pressure on ukraine now when you appear to be gaining the advantage on the wider diplomatic front? pauli on the wider diplomatic front? paul adams in kyiv. _ on the wider diplomatic front? paul adams in kyiv, thank you. clarence house says the prince of wales has tested positive for covid—19. prince charles received the result this morning. our royal correspondent nick witchell is here. what more do we know? a routine test this morning. — what more do we know? a routine test this morning, positive. _ what more do we know? a routine test this morning, positive. so _ what more do we know? a routine test this morning, positive. so charles i this morning, positive. so charles is self isolating. it's the second time he has had covid, he had it first at the start of the pandemic in march of 2020. he is triple

vaccinated and we can assume he is coping with it ok. but two days ago on tuesday he was at windsor for an investor chip and met the queen. she had got back from centring on the day before. as epic buckingham palace says the absolute minimum about anything to do with health. all royal sources will say is that the queen is showing no symptoms of covid. they will not say whether she has had a test or whether that test was positive or negative. the situation is being monitored. also of course, prince charles has met a number of other people in the last 48 hours. last night he was at a british museum for a function for the british asian trust and he met a number of people there, including the chancellor she soon checked and home secretary pretty patel. —— chancellor rishi sunak. the duchess of cornwall, who was also at the function last night, tested negative in a routine test this morning and continued with her engagements today. in summary, charles is

positive and self isolating. the queen is showing no symptoms or stop the situation is being monitored. nicholas witchell, thank you. new figures show a record number of patients were facing long waiting times for hospital beds last month. nhs england says 122,000 people, a third of those visiting a&e, who were unwell enough to need a hospital stay waited over four hours injanuary. it's the latest sign of the strain on the health service this winter. students and teachers in scotland's secondary schools will no longer need to wear face masks in classrooms from the end of this month. the first minister, nicola sturgeon, says the change will take effect from february 28th, when all schools have returned from the half—term break. face coverings will still be required in other communal and indoor areas within high schools, but this will be kept under "regular review". wales' first minister, mark drakeford, has tested positive for coronavirus and is self—isolating.

it comes on the eve of the release of his latest review of coronavirus legislation. the economy minister, vaughan gething, will now lead tomorrow's news conference on any proposed changes to wales' covid rules. last month, bbc news revealed there were 100 people with learning disabilities and autism who'd been detained in a hospital for more than 20 years. since then, several people across the uk have been in touch regarding their own battles to have loved ones released. our correspondent, jayne mccubbin, has been to northern ireland, to meet a woman who's been fighting for 3h years to bring her brother home. it's a journey i will never forget. there was a lot of crying, a lot of weeping and wailing. this was thejourney which broke brigin's family. my mother was in the back of the ambulance and i was with her. and the ambulance crew

were trying to prevent brian from hurting himself. 3a years ago, this was the journey which took her brother to the hospital where he is still detained today. he hasn't moved, other than to move to a different ward. he is still within the walls of the same place. you needed help, you needed support? yeah, he did need help, but he also needed to come home whenever he was ready to come home. which hasn't happened. i've travelled to northern ireland to meet brigin. good morning. good morning, hello. one of thousands of families across the uk fighting to bring a loved one home. that's our brian. we've all now got a copy of that in everybody�*s house. he is still a part of the family. between his mum and seven siblings, brian had originally thrived. at that stage he couldn't even sit up without support. but as he turned 21, life changed for them all.

increasingly unable to cope, he was detained under the mental health act. they were told he'd be back here in 12 weeks. 3a years since he went into the hospital, and 25 years since the doctors said he was fit for discharge, brian is still sitting in the hospital. a quarter of a century. quarter of a century. you all stayed close because you will knew you needed to be here when brian came home. we always kept hoping and thinking that he was going to be able to come home. but brian can only leave with the right community support. today they launched a judicial review to force authorities to provide that. mostly his whole adult life has been spent in hospital. and that hospital is muckamore abbey. the hospital at the heart of the largest abuse investigation in the history of the nhs. to date, over 70 staff have been suspended. brian is nonverbal, he can't communicate through speech. people who can't speak up forthemselves, people

who can't defend themselves. it's so awful. i just... a public inquiry has opened. i can't. brigene will be her brother's voice. belfast health and social care trust said no one should call a hospital their home, but due to the complex care needs of many long—term patients, resettlement can be challenging. for brigene, it isn't complex. it is simple — brian needs to be home. brian has been deprived of the love of his family. one day she hopes she will make this journey for the very last time. we'll never give up. as long as we live, we will keep on trying to get brian to a place where he can live the rest of his life in peace and happiness. never give up. jayne mccubbin, bbc news. our top story this evening... as he meets british troops

in poland, borisjohnson warns the crisis over ukraine could be entering its most dangerous moment. and still to come... insulating britain — why two thirds of homes in our ageing housing stock would benefit from better insulation. coming up in sportsday on the bbc news channel... sebastian vettel says f1�*s removal of taking the knee before races |sn' t progress" we speak to the aston martin racing driver at the launch of their new car for the upcoming season. it was one of the most dramatic moments in recent footballing history — the danish footballer christian eriksen collapsing on the pitch last summer, having suffered a cardiac arrest. now he's back, having signed for the premier league club brentford after being fitted with an implantable cardioverter defibrillator. it's a device that will restart his heart, should it stop again. in an exclusive interview, he spoke

to our sports editor, dan roan. they were the shocking scenes that left football fearing the worst. the cardiac arrest suffered by christian eriksen during last summer's euros was among the most distressing moments the sport has witnessed. but, with the world watching on, the denmark star survived and, eight months on, he's now been handed the chance of a remarkable return with brentford. fresh from training and in his first interview since signing for the premier league club, he told me just how much it meant to be back doing what he loves. it's going to be very special to be able to walk out on the pitch and play a match again. yeah, it's going to be amazing. when you touch the ball again, you get the feeling back, you get the adrenaline, you get the excitement. it's been some tough months, but i'm happy where i am now. with his partner, sabrina, watching on and team—mates forming a protective shield, eriksen was saved by the swift actions of medics, who managed to revive him through cpr and a defibrillator. i mean, i was gone, what i've heard, from this world

forfour orfive minutes, so they got my heartbeat back. can you remember what happened in the seconds before that collapse? i don't remember everything. the throw—in, the ball hitting my knee and then obviously i don't know what happened after, and then i wake up with people around me and feel the pressure on my chest, trying to get my breathing back, and then i wake up, i open my eyes and i see people around me. i didn't really understand what was going on. what did you think at that moment, when you realised what had happened? yes, i didn't believe it. i didn't believe that was me. how fortunate do you think you are? for me, it was unlucky in a lucky place. the doctors there to save me that quickly. so, like before, i'm really grateful they were in that place. has it changed you as a man? i think i see my family in a different view, compared. i loved my family before, but even now i think i love them more. eriksen! another one to spurs!

in seven years at spurs, eriksen established himself as one of the world's best midfielders, but he had his contract at inter milan cancelled as he is now fitted with a small heart—starting device that doesn't allow him to play in italy. but, having trained since december, he is confident his fairy—tale return with brentford can prove a success. for me, of course, when it happened and the first few days after, i didn't think about playing again, of course, because i didn't know what was going on and i wanted to get all the tests done and get to talk with all the doctors and see what is the possibility and what is not. but, after less than a week, they said, you have an icd, but otherwise nothing has changed. you can continue a normal life and there's no limits to what you want to do. is it sometimes hard to believe still what did occur that day? yeah, definitely. it's a bit out of the world experience, weird, because it actually did happen and i was where i was, but to see where i am now, it's very weird.

the danish footballer christian ericsson speaking to our sports editor, dan roan. the head of the metropolitan police says she expects to be held to account for her leadership. yesterday, the mayor of london, sadiq khan, said dame cressida dick had "days and weeks" to show she could restore public confidence in the force. it comes after several recent incidents and a report which found officers at one police station had displayed racism, sexism, misogyny and homophobia. dame cressida told the bbc the problems couldn't be blamed on a few rogue officers. a £290 million package of support has been announced in scotland to help people affected by the soaring cost of living. the scottish finance secretary, kate forbes, confirmed there will be £150 council tax rebates for people living in bands a to d. she said the money will either be given as a direct payment by local authorities or used as credit

towards council tax bills. government figures show 19 million homes in the uk are in need of better insulation, with two in every three leaking heat. the chief advisor on climate change says ministers must do better and that insulation is the way out of the current energy crisis. the uk is believed to have some of the oldest and draughtiest housing stock in europe. here's our climate editor, justin rowlatt. so you've got lots of heat coming out of this window here and again, under this window upstairs, we've probably got a radiator here. that's money coming through your wall. we are hunting for draughty homes using this thermal camera, and it is easy pickings here in manchester. virtually every home has insulation issues. you can't really see the wall. and here is the difference insulation can make. how would you rate this house? this house is definitely losing less heat, especially from the weak spots that were identified

on the other houses. but just look what it took to give the house an insulation makeover. so there's insulation inside the room here, the windows are double glazed and the space under the floor is insulated, too. up here, at the top of the house, the entire roof area has been insulated as well, so the walls used to look like this, bare brick. but they've put in this wood fibre insulation, external insulation, and the windows are double glazed. in monetary terms, it's saved 40% off our gas on the heating, and it's made a really big difference to the comfort of the house as well. but here's the rub. even at current energy prices, it will still take at least 20 years to cover the 36 grand it cost. down in london, it's this man'sjob to mark the government's homework on climate, so how is it doing? well, it's a d. could do much better, i think. so that is something

for the government to think about. i think the government's policy on insulation has been very, very ineffective. it really is very poor. we need something that dramatically changes the number of insulations that we do today. so this year we will be in the tens of thousands of installations. we really need to scale that up to something more like half a million a year and to do that quickly over the next four or five years. but, if it's hard for middle—class homeowners to afford insulation, it's even tougher for local authorities like blackpool. energy—efficient homes are popular with tenants though. perfect. but it would cost £125 million to bring all blackpool's social housing up to the standard ofjean's perfect flat. and the council says it simply can't afford it. so what does britain's climate chief think the government should do? we know that we need a sharper incentive for most people to make these investments in improving the energy efficiency of the home that they live in. so the government really does need

to step in. so, when you ask why so few homes in britain are well insulated, here is the answer. it's just so expensive. without some help, most of us will find it tough to get it done. justin rowlatt, bbc news, blackpool. at the winter olympics in beijing, the medals for the team figure skating competition are still to be handed out, more than three days after the event. olympic officials say there's an ongoing legal issue, after russia's skaters won gold. there are now reports one of the team tested positive for a banned substance. laura scott has more from beijing. she's the teenage sensation whose taken the figure skating world by storm. now, kamila valieva appears to be at the centre of one. three days ago, the 15—year—old made olympic history, landing a quadruplejump — helping the russian olympic committee to gold in the team event.

but the medal ceremony still hasn't taken place, and unconfirmed reports in the russian media say the reason is that valieva's tested positive for a banned substance. the authorities are remaining tight—lipped on the subject. there is a legal issue going on, i can't say anything more than that. at the moment, it's speculation, i can't comment. i think we have to wait, sorry, we have to wait with patience for this case to find its way to some kind of conclusion. because valieva is under 16, she wouldn't have to be named if she were charged with an anti—doping rule violation, and her coaches and entourage would automatically be investigated for any potential involvement. earlier, her team—mates weren't in the mood to talk. sorry, no comments. well, the very presence of russian athletes at these games had already been a source of controversy — given the country is still serving sanctions from its state—sponsored doping programme. the athletes are appearing under the banner of

the russian olympic committee, but they wore the country's colours on their kit, when they win, they hear tchaikovsky — meaning that for many, they are russia in all but name. valieva was mesmerising today, even in practice. but there are now lingering doubts over whether we will see her compete again on the beijing ice that she's made her own. laura scott, bbc news, beijing. time for a look at the weather. here's chris fawkes. we had one or two issues this morning in parts of scotland, with some hill snow causing problems on the roads and strong winds gusting to 70 mph in the western isles. that was from this little area of low pressure that is now exiting stage right. if we zoom out, we have our next weather system waiting to bring in, to bring wet and windy weather for the weekend. between these two, relatively cold air, a ridge of high pressure building in, and overnight

that will switch showers, so increasingly clear skies, the winds getting light and it will be cold, with widespread frost developing in many places. the coldest temperatures likely in somewhere like braemar, where it could get down to —10. in coastal areas, the risk of icy stretches for friday morning. for many of us, a glorious winter's day on the cards, with some show in the morning and afternoon. a few showers of the irish sea and western scotland and northern ireland. the cloud will thicken up through the day ahead of the next weather system. temperatures close to average, six to nine. for the weekend weather prospects, the weather turns more unsettled, with outbreaks of rain spreading in off the atlantic. lots of showers for scotland and northern ireland but occasional bright spells. the heaviest rain set to move into parts of wales and western england. around

eight or nine celsius, perhaps a bit milder in northern ireland.
