to unprecedented glory, lizzy yarnold and laura deas turning dreams into reality, rewriting the record books. commentator: lizzy yarnold next, the olympic champion, can she make history and win it again? yarnold went into her final slide in second place, but conjured an imperious display and the fastest time any woman has produced on this track to enter sporting folklore. that is a gold medal winning run, i'm sure of it. so it's gold for lizzy yarnold. she's defended her title and become the most decorated british winter olympian in history. she was joined on the podium by team—mate laura dees. the pair rounding off the most successful day their nation has ever seen at a winter games. as yarnold jumped into the crowd to join the celebrations, how did she feel? exhausted! now a back—to—back champion, the 29—year—old couldn't

hide her delight. i'm just so relieved that i've done the race, been consistent and laura and i are on the podium together. for her parents, judith and clive, another moment to savour. from the mixed season she's had to win the gold medal here today and we have a bronze medal as well through laura, is absolutely mind—boggling. the success story was started by the youngest member of team gb, 19—year—old izzy atkin saving her best until last to take bronze in the slopestyle and become britain's first official olympic skiing medallist. great britain's izzy atkin takes a bronze. i'm still kind of speechless. ican't... i'm really excited, really happy, i'm stoked with how i skied and also stoked to win the bronze. the day was however tinged with disappointment as elise christie crashed out of the 1500 metres short track speed skating and was later disqualified. commentator: christie has crashed

again now in the semifinal. she went to hospital as a precaution but was given the all clear and may yet race in the 1000 metres as she bids to avoid a repeat of her nightmare in sochi four years ago. but that will do little to dampen the british euphoria as they delivered on snow and ice a super saturday to live long in the memory. david ornstein, bbc news, in pyeongchang. i've been speaking about today's historic achievement with the former performance director of british skeleton, simon timson. he described the winds today as sensational. it is absolutely incredible. i am on a ski holiday and could hardly ski this morning, my legs were jelly with anticipation. we were all hanging around the tv in a mountain restaurant. my wife had to quieten me down with cheering when they secured the medals. the hardest bit was looking at laura

‘s face when lizzie came down, thinking, i going to get squeezed out of a medal? then the austrian made a couple of big mistakes have lost out. we were celebrating gold and bronze, which was incredible. how long ago did the team start working and preparing for the kind of success we are now seeing? it all started back in the late 90s with two fantastic athletes. kristin went on to be a world champion, alex won bronze in 2002. that enabled us to put in place a 10—year strategy to try to win an olympic winter gold medal. amy williams fulfilled that in vancouver. lizzie repeated four years later in sochi. now the first—ever british winter olympians to defend their title and win a second gold medal.

i don't think who has been in the programme for 16 years and succeeded me as performance director, would have dreamt we would win half the medals on offer at these games. it truly is something very special. a huge achievement for the athletes, the coaches and all the support staff. and don parsons took a medal on thursday, let's not forget him. what makes a great skeleton athlete? the formula is quite simple. they need to be a really good athlete, fast sprinter, and you saw laura and lizzie beat two of the fastest starters in the race. it starts fast but you have to be calm and cool on the slides, make small adjustments and steers. good hand eye coordination, really good feel for the slide on the ice. the different pressures

on the corner, it's quite a sensitive piece of equipment. it is highly skilled driving that the difference. that makes the difference. it looks like you are just throwing yourself down a slope on a tea tray, to the untrained eye, how important are these suits they work? are these suits they wear? nobody is too disappointed, but the opposition spent a lot of time talking about our suits. at the end of the day, you have to run really fast and then it comes down to the drive. the skill of steering the slide through the corners, controlling the pressure, avoiding the little bumps that shave off hundreds or tenths of a second. the suits help but you still have to start fast and drive well. and have nerves of steel? absolutely, that really helps. how cool and calm was lizzie on that final run? she put down a track record that meant she had the two fastest times in the race of the first run and fourth run, the

biggest pressure runs. the true hallmarks of a champion. let's not forget laura as well. fantastic final run. it gave laura the opportunity to win a bronze. a brilliant day for british winter sports. three medals we probably wouldn't have thought about going into the day. a sensational performance by team gb. a very happy simon timpson. ukip have voted to remove their leader henry bolton after less than six months in the job. 63% of party members supported the motion of no confidence, following the controversy over racist messages sent by his then partner. the party will now have it's fourth leadership election since 2016. the interim leader is gerard batten, one of the party's mep‘s. henry bolton said he was disappointed by the result, but was unsure if ukip had a future as a political party. if you look at the challenging event

lest that they have embarked upon, the egm today, interim leadership, then another leadership contest, and quite rightly we are talking 90 days down the road, that's exactly the same time as local government elections. in between all that they still must hold the national executive committee election which they have postponed twice for whatever reasons. it is a hugely challenging time for the party. a time when it should be on the battlefield, delivering messages on getting out of the eu. why do you think you lost today? it range of reasons, the main one that any seed does hold a huge amount of power in the party. i wanted to reduce that power, so we could professionalise the party. make it fit for purpose,

but whenever you implement change there are some people who use own interests are threatened by that. change is not always an easy thing for people to accept. i spoke to suzanne evans, former ukip deputy chair, who called on nigel farage to return as ukip's leader. nigel farage has backed the last three utterly useless leaders of ukip. he backed diane james, who lasted less than two weeks. he backed paul nuttall who turned out to be a disaster. he backed henry bolton who turned out to be even worse. nigel has got us into this position, and i think he should come back and sort out this mess. he has had terriblejudgment but was a very good ukip leader himself. we need somebody in ukip now view is a strong leader, who can really fight for this party and fight for this country and fight for the brexit, the clean brexit,

that the people voted for. i want to say to him, come back, i know you at i have had our differences but come back, lead this party. if you are not prepared to do that, and you are being paid a huge salary by the european parliament to be a full—time politician, and not an occasional politician and a full—time study of celebrity, do your duty by this party and this country. if you don't want to, then please get out of ukip‘s way and let them choose a leader without any interference from you, because you have shown such poor judgment in the past. and we'll find out how this story — and many others — are covered in tomorrow's front pages at 10:30 and 11:30pm this evening in the papers — our guestsjoining tonight are nigel nelson, political editor of the sunday mirror and political commentator, jo phillips. theresa may has said cooperation on security with the european union after brexit calls for a new "deep and special partnership." in a speech in germany, the prime minister warned that failing to work together would put

everyone at risk. in response, the president of the european commission jean—claude juncker said he'd welcome a close security alliance — but it must be negotiated separately from other brexit issues. our political correspondent vicki young reports from munich. in defence and security the uk is a significant player and the prime minister hopes that will get her a special deal. she arrived in munich keen to lay out britain's contribution. generous spending on defence and expertise it wants to share even after brexit. theresa may urged the eu to take a practical approach. this cannot be a time when any of us allow competition between partners, rigid institutional restrictions, or deep—seated ideology, to inhibit our cooperation and jeopardise the security of our citizens. she's calling for a new security treaty so that the close partnership can continue. failure to agree one would have damaging consequences, she said. we must do whatever is most

practical and pragmatic in ensuring our collective security. those who threaten our security would like nothing more than to see us fractured. some listening to this were left bewildered. the brexit decision from the point of view of us inside the eu is extremely regretable. things would be so much easier if you stayed, so here comes the question... applause. mrs may pointed out that brexit was a democratic decision politicians should respect. one senior brussels figure seemed to agree. the commission presidentjean—claude juncker said the eu wasn't at war with the uk and didn't want to take revenge on the british people. he said the security bridge would be maintained but you couldn't mix it up with other issues.

so it's a pretty familiar message from theresa may. the uk is leaving the european union but that doesn't mean that close cooperation needs to end and it's a blunt message too, saying to europe's leaders, don't let your ideology get in the way of the safety of our citizens. the government hopes today's speech will show it's acting responsibly, not wanting to drag the important issue of security into fraught brexit negotiations. two members of the same family — a 15—year—old boy and a 72—year—old man — were killed when the car they were travelling in collided with a train at a level crossing in west sussex the emergency services were called to barns green near horsham, shortly after 8.30 this morning. no—one on the train was hurt. the headlines on bbc news: lizzy yarnold becomes the first british winter athlete to defend an olympic title after winning gold in the women's skeleton — laura deas took bronze. ukip party members have voted

to sack their leader henry bolton — less than six months after he took on the role. theresa may warns european union leaders not to put lives at risk by blocking a security deal after brexit because of "deep seated ideology". sport now, and time for a full round up from the bbc sport centre. let's begin with great britain's most successful day at a winter olympics.... lizzie yarnold became the first british winter olympian to successfully defend a title. she's skeleton champion once again. team—mate laura deas took bronze — the first time there have been two british medallists in the same event. izzy atkin won bronze in the slopestyle earlier on saturday, but there was more heartbreak for speed skater elise christie. david ornstein reports from pyeongchang. guiding great britain to unprecedented glory,

but they got their second after the break. lukaku again. southampton made it through to the last eight with a 2—1 win at west bromwich albion, this goal from dusan tadic proved to be the winner. it follows an eventful week for west brom, afterfour of their players broke a curfew and reportedly stole a taxi while in spain for warm weather training. brighton are through to the next round after a 3—1win over coventry city. jurgen locadia with the seagulls opener — a goal on his debut after completing a 1k million pound move from psv eindhoven in january. defender connor goldson made it 2—0 by half time and leonardo ulloa headed in the the third just after the hour mark. brighton are through to their first quater—final since 1986. the draw has just taken place for the quarterfinals. sheffield wednesday and swansea still both in it after their 0—0

draw earlier, they will play rochdale or spurs who play theirfifth round match tmrw. manchester united are at home to brighton. leicester play chelsea and wigan or man city who play on monday, will play southampton. that's all the sport for now. we'll have more for you on bbc news throughout the evening. survivors of the shooting at a florida school have been taking part in a rally demanding tighter gun controls. protesters in fort lauderdale chanted ‘no more guns' and angrily attacked politicians at an emotionally—charged event. earlier, president trump met survivors of wednesday's attack, in which 17 people died. yesterday the fbi admitted it failed to act on a tip—off about the gunman. aleem maqbool reports. some survivors of the school attack are still being treated in hospital.

as he promised, the president visited here, albeit very briefly. reporter: did you see some victims, mr president? yes, i did, i did indeed and it was very sad, something like that could happen, but the jobs the doctors do, the nurses, the hospital, first responders, law enforcement, really incredible. donald trump also met officials from the emergency services. what he didn't do though was answer any questions about the need to tighten gun laws. more funerals are being held for the 17 people who died. most of them teenagers shot in their classrooms. this gun show was advertised close to the very school where the shooting took place. we weren't allowed in but spoke to people as they left. is it worth sacrificing guns if it means there will not be any mass shootings or school shootings? i don't think it would make a difference, that's my honest opinion. if it was proven to me, sure, but unfortunately that's not the case. life is delicate, you could kill

somebody with a pencil. barking up the wrong tree. and with more than 300 million firearms in circulation in this country, how do you change a gun culture that's become such an integral part of american life? aleem maqbool, bbc news, in florida. a court in pakistan has handed down four death sentences to a man who kidnapped, raped and murdered a six—year—old girl, zainab ansari, last month. the girl's family has called for imran ali to be publicly hanged. our correspondent secunder kermani has been following the case. these are the last images of zainab ansari alive, being led away by the man who would rape and kill her. her body was found on a rubbish dump five days later. her attacker was 24—year—old imran ali, an acquaintance of her family. he was identified on the basis of dna evidence.

after a trial lasting just four days, today he was sentenced to death. he has been convicted on four different counts and has been sentenced to death. the discovery of zainab‘s body led to angry protests in her hometown. at the trial, her killer admitted to having assaulted or murdered eight other young girls here over the past two years. many believed he could have been stopped sooner. her family welcomed today's verdict. translation: we are satisfied with this verdict of the death sentence, but our next demand is that he should be punished and hanged publicly. the murder of zainab ansari has sparked unprecedented discussion of child abuse. normally a taboo topic in pakistan. but campaigners believe more needs to be done to educate both children and parents about the dangers, and to ensure the authorities properly investigate cases. the families of these victims now

have some semblance ofjustice. but for many, it may feel too little too late. the president of haiti has called for an investigation into the activities of aid agencies working in his country, saying that the scandal involving some oxfam workers was just the tip of the iceberg. he said the charity doctors without borders had repatriated some of its staff from haiti without any explanation. the charity said it takes any reports of staff misconduct seriously and are seeking to clarify the questions raised. an earthquake has shaken wales and parts of west england. you can see the large red lines here from the british geological survey , they show the tremor which was a magnitude of 4.4. the epicentre was around 12 miles outside swansea. tremors of this scale are only felt in the uk every two to three years.

i have been speaking to some people who felt the earthquake. i was outside one of the shots, kneeling down with my toddler and my boys, it felt like somebody came and nudged me on the shoulder. i looked round to see if anyone was there, no one else had reacted. a lady came out of the shop and said to her husband, did you feel that? i looked up husband, did you feel that? i looked up and said, was that the ground living? they said yes. it was reassuring that i hadn't gone mad, but it was... ever like a couple of inches, must only be millimetres of course. felt like being off—balance. does that sound familiar?|j course. felt like being off—balance. does that sound familiar? i was in my home at the time. i saw some birds suddenly fly past the window,

they must have been on the patio. they flew up quickly. i wondered what spooked them. probablyjust a millisecond later, everything on the ceiling started to shake. it was really peculiar because we have spotlights in our kitchen and i could see them shaking, it looked a little bit like you would see shaky video footage or camcorder footage, that's the impression i had. at the same time, there was this rumbling, muffled sound. but it wasn't in the house, it was somewhere distant. i wasjust trying to house, it was somewhere distant. i was just trying to work out what was happening because none of this made any sense to me. james, what did your toddlers make of it? they were far too interested in the doughnuts i had just bought them, u nfortu nately. i had just bought them, unfortunately. they are not going to realise. every two or three years we have these things, in the morning you go on facebook or a tweet, i

woke up and i always miss them, so it was quite nice to realise, i wasn't going mad, i have actually experienced it. sugar or a tremor when you are two yea rs sugar or a tremor when you are two years old, what would you pick? a new scanning system has revealed a painting underneath picasso's picture — "a crouching woman" the picture underneath is of the catalan landscape probably painted by one of his assistants. it seems that picasso turned it 90 degrees and used the shape of the landscape to create the woman's crouching pose. the discovery has been unveiled today at an international science conference in austin texas from where our science correspondent pallab ghosh reports. picasso's crouching woman — worth millions. a painting from his blue period. but there's more to it than meets the eye. the conservators at the gallery analysed it with a new type of scanner, and this is they discovered. underneath it is a painting of the barcelona landscape by a fellow artist. but turn it 90 degrees and bring back the crouching woman,

and you can see that picasso has used the landscape as the basis of his painting. it helps date the painting, it helps determine where the painting was made. but it also gives us a sense of the artist with whom a particular painter was engaging. and i think these insights do help ask us new and more interesting and more scientifically accurate questions. the contour of the hills in the background becomes the crouching woman's back, and she takes on the shape and form of the catalan countryside. until now, only the wealthiest galleries could afford to scan, and even then, it was only for great works of art. but the new system is cheaper and portable, and so can be used by anyone to find the secrets behind any painting they want. here at the harry ransom center, the curator has questions about this portrait of the american composer, george gershwin. in particular, whether a friend in the front row was painted out

and seated further back because he fell out of favour. this figure here is oscar levant, who was a friend of george gershwin, but also a rival. so stories have circulated for years that perhaps he, as the only recognisable figure in the second row, was perhaps moved — demoted, as it were — from appearing in the first row. so that is one of the questions we can potentially find out with this technology. can i take a look? tracy has asked the team that developed the scanning system to help her answer that question. they scan each stroke of the brush, millimetre by millimetre. it's a collaboration that the team wants to extend to more galleries. many of these paintings are waiting to tell their secrets, so with the x—ray flourescent spectrometer, we can help them talk to us more. the team hopes the widespread use of their scanners will increase our understanding of artists, their thought processes and the way they worked.

how thrifty they were to reuse things. time for a look at the weather with darren bett. i hope you may be best of sunshine, because there won't as much tomorrow. this is what is coming your way. it will be spilling across the uk to night and into tomorrow, and already some cloud arriving in the far north west. ahead of that, clearer skies, no wind, so turning cold very quickly, with foggy patches in the vale of york. increasing cloud in wales, that might lift the temperatures but frost more likely further north and east. the fog will lift to the morning and the best
