good afternoon and welcome to the bbc news at one. as tensions rise over a possible russian invasion of ukraine, western nations have again made it clear to moscow that any military action will result in massive sanctions that would have serious consequences for the russian economy. the g7 group of the world's most developed countries, including britain, made the warning as a spokesman for ukraine's president insisted his country's ambition is still tojoin nato, as set out in its constitution, despite the ukrainian ambassador to britain suggesting otherwise as a means of avoiding war. russia has long wanted ukraine to drop its desire tojoin the military alliance. moscow now has up to 130,000 troops encircling ukraine but maintains it has no plans to invade. 0ur diplomatic correspondent james landale has the very latest. kyiv this morning, another day in a

process takes years and one of the conditions is that you can't be at war. the country has been at war for eight in the east, but signing up would also put it in direct conflict with russia. the kremlin has made that clear, saying it would welcome a guarantee of not drawing though my joining, that it would ease security concerns. and they want an agreement... joining nato, in the words of the uk's uk ambassador of ukraine, that is not going to happen by wednesday. find ukraine, that is not going to happen by wednesday-— ukraine, that is not going to happen by wednesday. and to you, caroline, in moscow. — by wednesday. and to you, caroline, in moscow, picking _ by wednesday. and to you, caroline, in moscow, picking up _ by wednesday. and to you, caroline, in moscow, picking up on _ by wednesday. and to you, caroline, in moscow, picking up on james's - in moscow, picking up onjames's point, nato membership is what mr putin detests, so ukraine potentially shelving that ambition, could that deter war? that potentially shelving that ambition, could that deter war?— could that deter war? that was certainly what russia _ could that deter war? that wasl certainly what russia demanded could that deter war? that was - certainly what russia demanded back in december, clive, but at the moment, _ in december, clive, but at the moment, hearing from the kremlin

at the pumps reach record highs across the uk. the motoring organisation the aa says the cost of petrol increased to 148 pence per litre for the first time this weekend. 0ur transport correspondent katy austin is here. a direct impact, then, for all of us from what is going on in ukraine. earlier today, the price of oil hit a seven—year high, at about $96 a barrel, before falling back slightly. tensions around ukraine aren't the only thing that had been pushing up wholesale prices. another big one is the resurgence in demand as global economies have reopened full stop but concerns around the potential for conflict have definitely driven those prices up further, because of the impact it could have on supply. it doesn't happen overnight, but these increases do feed through into the amount drivers who have paid for theirfuel at amount drivers who have paid for their fuel at the amount drivers who have paid for theirfuel at the pump, and motoring groups say that yesterday the average cost per litre of petrol

went above £1.48, surpassing the previous record, set in november. diesel has also hit a record high. the rac is predicting that records could now be set daily and it thinks retailers are keen to pass on the wholesale increases quickly, and the cost of living crisis has been ratcheted up another notch. it comes as households and businesses are facing various cross pressures. thank you. a long—awaited public inquiry into one of britain's biggest miscarriages ofjustice has just begun hearing evidence. more than 700 post office branch managers were wrongly convicted, and thousands lost their businesses when faulty accounting software made it look as if money had gone missing from their tills and they'd stolen it. here's charlotte gallagher. a moment for celebration after years of anguish and struggle. jo hamilton, here on the right, isjust

one of the innocent people whose lives were ruined because of a faulty post office it system. her conviction was quashed last year but now it is time for answers from this public inquiry. i had a criminal record for 13 years, that i didn't deserve, and that impacts on your work on your finances and everything. my mum and dad aren't here, they weren't here to see my conviction quashed, because they both had strokes and died, which i'm convinced was as a result of what happened to me. in total, 706 former sub—postmasters were convicted for crimes they didn't commit. slowly, those convictions are being overturned. 72 so far. but thousands more post office staff lost huge amounts of money so, the government will foot the bill for compensation. the it system at the centre of this scandal is called horizon, developed by the software firm for jitsu.

essentially, it couldn't add up properly so post office managers were accused of stealing sums of money that never existed. lives were ruined, families were torn apart. families were made homeless and destitute. reputations were destroyed. this public inquiry beginning today is aiming answer these questions. when did it become clear horizon wasn't working? and why did senior managers keep blaming sub—postmasters when the issues emerged? no—one has been held responsible so far. the post office has said sorry to victims likejo. for the victims, the answers can't come soon enough.

i used to open the post office at eight o'clock in the morning and shut at eight o'clock at night. i worked seven days a week and i was the only post office that was open seven days. the post office has said sorry to victims. but many people want more than an apology. charlotte gallagher, bbc news. one of those imprisoned after being wrongly convicted was tracy felstead, who was sent to hollowayjailfor three months when she wasjust 19. last year, along with 71 others, her conviction was overturned. hayley hassall, from the bbc�*s file on 4 programme, has been following her story. i'm feeling loads of different emotions. i'm scared. scared of what's on the other side of those gates. i'm angry. it needs to be done. it needs to be put to bed. at the age of 19, tracy

was prosecuted and sent to holloway prison for stealing more than £11,000, something we now know was due to a faulty computer system called horizon. she's come back here today for the first time in 20 years, in the hope that this will somehow help with her recovery. this is my cell. this is your cell? yeah, that's my bed. i remember saying to a girl, i hadn't done the crime. and she said, oh, none of us have. see... you couldn't even protest your innocence in here. i never thought i could come here, ever. tracy spent several weeks in this group cell, before being moved to one of her own. this was my cell, cell 21. it's now 20 years since you were in this prison. how has your life

changed by being here? although it's made me the person i am today, it's, it's made me not the person i want to be. i don't want to be that person who is scared of noises, who, you know... it broke my marriage down. it's taken its toll. no amount of money will ever change what happened. the only thing i can do now is look forward to the next 20 years. i always say to my children, neverjudge a book by its cover. you don't know what somebody�*s been through. and now i understand that sometimes people are sent to prison for crimes they didn't commit. i still feel very surreal that i've just done that. i want closure for everybody. people to be compensated, fair and final compensation. we need answers as to who knew

what, when and why. you can hear more about tracy's story on file on 4 in first class scandal, on bbc radio 4 at 8pm tomorrow night, or at any time on the bbc sounds app. our consumer affairs correspondent, colletta smith, is in central london where the inquiry is taking place. this whole affair is so appalling. what is it that those who were wrongly accused want from the acquired —— the inquiry? tt is wrongly accused want from the acquired -- the inquiry? it is an easy question — acquired -- the inquiry? it is an easy question to _ acquired -- the inquiry? it is an easy question to answer, - acquired -- the inquiry? it is an easy question to answer, and i acquired -- the inquiry? it is an i easy question to answer, and that acquired -- the inquiry? it is an - easy question to answer, and that is accountability, because no one has yet been held to account for what has happened to those individuals, from within the post office, fujitsu, who sold the software to the post office, or indeed the government as a whole. we have heard

at the inquiry that this is not going to be a dry inquiry into what they describe as an it project gone wrong, because as you have been hearing, as we have covered so often on bbc news, this is a story about people and the impact it has had on their lives. budget set fee has been their lives. budget set fee has been the first witness this morning to begin to give evidence. but it is the tip of the iceberg. more than 2000 people lost their businesses, were driven into bankruptcy because of this, and more than 700 were convicted, received criminal convictions, many, like tracy fell said, were sent to prison as a result. and for them, it is notjust about getting those convictions overturned or receiving financial compensation but finding out why the post office held onto that belief that they could still use the software as a basis for conviction, even though there were faults known within that system at the time. that's what this inquiry is trying to get to the bottom of, but it's going to take more than a year before any conclusions are reached.

the labour leader, sir keir starmer, has confirmed he's received death threats following boris johnson's false claim that he failed to prosecute the paedophile jimmy savile. sir keir had to be shielded by police from an angry mob outside parliament last week, and says the prime minister's slur has "fed into right—wing conspiracy theories". police are investigating the online death threats. the world anti doping agency says it's disappointed by the decision to allow a 15—year—old russian figure skater who failed a drugs test to continue competing at the winter olympics. kamila valieva's positive result in december only came to light last week, after she'd helped russia win the team skating event in beijing. the court of arbitration for sport has ruled that because of valieva's age, and the timing of the test result announcement, she should be treated as an exceptional case. laura scott has the latest from beijing. cleared to skate, but not

cleared of scandal. kamila valieva returned to the ice under the scrutiny of the world after the court of arbitration for sport ruled the 15—year—old should be able to continue competing in beijing, despite testing positive for a banned substance. no provisional suspension should be imposed on the skater. in particular, the panel considered that preventing the athlete to compete at the olympic games would cause her irreparable harm. the panel said a series of exceptional circumstances were behind its decision, including that valieva is only 15 and the fact that her positive drugs test results came back midway through these games, 44 days after the sample was taken, meaning she had little time to mount a defence. the world anti—doping agency said it was disappointed by the decision because its rules don't allow exceptions to be made to mandatory provisional suspensions, including for minors.

meanwhile, the us olympic and paralympic committees said this appears to be another chapter in the systematic and pervasive disregard for clean sport by russia. it is damaging. it's very damaging, but at the same time you want to think that now maybe, yet again, we're at this point where something will be done in order to make sure that nothing like this can happen again. the international olympic committee announced that there won't be a medal ceremony in the figure skating team event, which was won by the russian olympic committee, including valieva. and there are other ramifications, too. should ms valieva finish amongst the top three competitors in the women's single skating competition, no flower ceremony and no medal ceremony will take place during the olympic winter games beijing 2022. a week since making olympic history on the ice, valieva is hoping to wow the world again with her skills. but she does so in the most controversial circumstances. laura scott, bbc news, beijing.

along with an estimated global audience of well over 100 million people. for the first time, the event famed for its half—time entertainment featured a celebration of hip—hop, with performances from snoop dogg, maryj blige and eminem. here's our los angeles correspondent sophie long. it was the day la had been waiting for, as the super bowl came back to its birthplace. i got the rams, i got the bengals. rams, bengals, rams, bengals... rams, baby! wheyy!! rams! time! the super bowl has come back to los angeles! - dwayne the rockjohnson injected excitement before kick—off. turns out that wasn't necessary. stafford, into the end zone! the rams were first to score and lead into half—time.

then, in a matter of minutes, the brand—new sofi stadium was transformed into a california house party for the first hip—hop half—time show, set on a glittering map of los angeles. dr dre and snoop dogg opened, 50 cent made a surprise appearance, in more ways than one. maryj blige dazzled. compton local kendrick lamar took over. then the crowd of more than 70,000 lost it to eminem. it had been billed as the super bowl�*s best ever. maryj blige killed it. dr dre, eminem, thank you for representing compton, and we love all y'all. all y'all are amazing. cincinnati put up a mighty fight. it looked like the trophy would be theirs, until the rams scored a touchdown less than two minutes before what became a dramatic, and for the bengals, heartbreaking end to the game. well, it was the hollywood ending

will be the subject of an internal investigation. our special correspondent lucy manning reports. cheering. brand—new series of love island, the wait is finally over... - caroline flack — we watched her on—screen. but those who really knew her wanted answers about her death. two months before the tv presenter killed herself, she had been charged with assaulting her boyfriend. two years on, her mother still doesn't have the answers about the way the police treated her. do you think she was treated differently because of who she was? totally. ijust think, erm, it was because who she was, yeah? it was because she was a celebrity? yeah, yeah. prosecutors originally said caroline should just be cautioned, but the met pushed for the presenter to be charged. the coroner later said she took her own life

because she was facing prosecution and feared the publicity. but it's now two years, and i've still not got an answer. and how does that leave you and the family feeling? it leaves us really... really sad and really angry, because, you know, you want to know why they charged her. she couldn't get over that, she couldn't see a way out. and that was, it was down to that. her mother put these questions to the met. she was so dismayed with their response, she complained to the police watchdog. it found the met�*s response was not reasonable and proportionate, telling mrs flack... "i do not consider your complaint has been fully addressed." it has ordered the met to do a proper investigation. what do you think about the fact that the police watchdog have forced

the met to investigate your queries properly? i think it's disgusting, but i think it's typical of the met as we see it now. there's no trust at all, no trust at all. the met has said it is rare to give a caution in a case of domestic abuse. the force told us the police watchdog found it had answered seven areas of mrs flack's complaint, but it had been directed to reinvestigate why it had appealed the decision to caution ms flack. our thoughts and sympathies remain with caroline's family, it said. but mrs flack feels her daughter, who had self—harmed that night and had mental health issues, was badly let down. she was fun, she just had these really dark times. as i say, usually she could get out of it, especially on telly. she loved herjob. i'm doing it for caroline, because there was so much

negative press around, and it won't bring her back, i know it won't bring her back, but i've got to do it for her. it's day ten of the winter olympics, and team gb has still to win a medal. it's 30 years since great britain returned from a winter games empty—handed, and the ambition this time round was three to seven medals. but not all hope is lost, with some promising contenders still to compete. here's our sports correspondent andy swiss. team gb�*s kirst muir... ten days, zero medals. britain have hardly soared so far at these games, but could kirsty muir finally give them lift off? atjust 17, muir is the team's youngest athlete, but she cruised through to the slopestyle final in sixth place and hopes even better is to come. solid run for kirsty muir from aberdeen. i feel like i definitely

had a few mistakes in the first run, which i'm hoping to clean up tomorrow, and then not as good on my second, but honestly so happy. yeah, just can't wait for it. herteam—mate, katie summerhayes, also qualified. after what's been a desperate games so far for britain, just maybe. and so team gb will have two skiers in the final here tomorrow, and with kirsty muir in particular, they'll have high hopes of that elusive first medal. a tied match to the very last stone. any other chances? the men's curlers are going nicely, edging out switzerland in dramatic style. and he's done it. that's a brilliant shot to finish things off. the semifinals are now in their sights. in the ice dance, meanwhile, britain's lilah fear and lewis gibson skated to the lion king soundtrack and secured a creditable top ten finish. i reckon she's been

shopping in beijing. but the day's strangest sight, france's lucille lefevre in the big air event, dressed as a tiger. why? well, despite being injured, she wanted a final jump before retiring. and although she finished last, at least she went out with a roar. andy swiss, bbc news, beijing. the film director and producer ivan reitman, who made the comedies ghostbusters, twins and kindergarten cop, has died at his home in california. he was 75. born in what is now slovakia, he grew up in canada, with his big break coming in 1978, producing the comedy national lampoon's animal house. our entertainment correspondent lizo mzimba looks back at his life. # if there's something' strange in the neighbourhood. ghostbusters was a phenomenon. # ghostbusters! when teenagers became cinema's most lucrative audience in the 19705 and 1980s, reitman had an almost unique understanding of their tastes. he slimed me. that's great!
