The north is to send its highest ranking official for years to the south to the games. Here he is kim yong nam, the ceremonial head of state, will lead a 22 member delegation to the south beginning on friday. It comes as the two nations put on an unprecedented show of sporting collaboration today, fielding a joint womens ice hockey team. It played an International Friendly against sweden. The bbcs laura bicker reports. Fierce and determined, the korean players head onto the rink to prove they are notjust pawns in a Political Drama or an experiment in sports diplomacy. They fight hard against high ranking sweden. Willed on by a crowd eager to witness a piece of history and waving the flag of a unified korea. Translation i was so touched, i feel so good because i felt the passion of the players and it felt like we were one together. But this teams formation has been controversial. The south korean hockey coach has had to tell players she has worked with for years that they have lost their spot to make way for North Koreans, such as this player. We are not allowed to ask the North Koreans any questions at the press conference, but the south korean coach was frank when i asked her about the challenges. Translation any players that have not been with us for the last four years, learning our systems and understanding how our team plays, it is difficult. North korean is different to south korean so for our Team Meetings it is going through to english, to south korean, to north korean, so the meetings take three times as long. The event feels like a celebration but playing as one team under one flag has not been welcomed by the Younger Generation in south korea. To them, unifying the two countries is a very distant goal. The north korean players will not stay with their team mates at the athletes village, they will be kept in separate accommodation and watched over by minders. As the olympics draw ever closer, language is not the only barrier this team faces. Laura bicker, bbc news, seoul. The pressure is continuing to grow on south africas president jacob zuma to step down. The top six officials from the countrys governing anc have arrived at his official residence in pretoria to discuss his future. Mr zuma is facing allegations of corruption and whether he can complete his term as president is looking increasingly uncertain. Heres the Bbcs Andrew Harding in johannesburg. He is swamped by scandal. South africas president jacob sooner has already been found guilty of breaking his oath of office jacob zuma and he has refurbished his home at taxpayer expense. More recently his controversial developments with the business family the guptill is as cause controversy. During the jacob zuma presidency, south africa has floundered, unemployment is soaring, amid a sense that senior officials could get away with anything. But in december, jacob zuma and his allies lost control of the governing anc and the new man, cyril ramaphosa, promising to end impunity. Everyone agrees that our state was captured by people who purported to be close to the president , who have been doing really bad things in getting into all and many state institutions. And suddenly there is real change in the air here. Prosecutors seizing this state farm in connection with alleged fraud by the guptill family and officials, and the courts pursuing corruption charges against president zuma himself. Pursuing corruption charges against president zuma himselfli pursuing corruption charges against president zuma himself. I think these are important moments in South African politics. In all likelihood we will see arrests and big people being caught up in this because we are seeing that the wheel is turning and momentum is developing and i dont think that there is any turning back. Fonau, jacob zuma is clinging to hisjob, but his allies are discerning deserting him and to night Party Leaders are meeting to night Party Leaders are meeting to discuss his removal. In places like zimbabwe and tenure we have seen this sort of situation turn ugly and dangerous and kenya. But south africa is a robust democracy and whether he is pushed orjumps, president zuma will soon be out of power and, most likely, in president zuma will soon be out of powerand, most likely, in Court President zuma will soon be out of power and, most likely, in court on corruption charges. It is a moment of drama and optimism for a country poised to exit the troubled president zuma era. Two people have died in a crash between a Freight Train and an amtrak passenger train in South Carolina. Early indications suggest the amtrak train was on the wrong track. Its the third deadly crash involving the National Carrier in just seven weeks. It isa it is a horrible thing to see, to understand the force involved. Two trains, that is about as forceful as you can get. The engine of the first engine of the Freight Train was torn up engine of the Freight Train was torn up and the engine of the passenger train which was headed south was barely recognisable. It is quite a crash. David willis has been following the story from washington. Those figures, 139 passengers on board, and eight crew, we know that the two people who died in the incident were both amtrak employees. This passenger train colliding with a stationary Freight Train south of colombia, which is the capital of South Carolina, just after 2am local time, and the speed given the passenger train at the time of the collision was 59 mph. 116 passengers, they say, were transported to local hospitals, many of them with minor injuries, but some broken bones but officials from the National Transportation safety board are on their way to the scene, as is normal, and that is the federal agency which investigates these incidents and they will look into it. Meanwhile the governor of South Carolina has said that it does appear that the amtrak train, the passenger train, was on the wrong track at the time of the collision. You mentioned it was the third serious rail accident in america in as many months. What sort of debate is there over rail safety there . |j is there over rail safety there . think this will prompt a renewed debate about rail safety here, not least because the South Carolina governor has prompted one, saying perhaps this is the time to have such a debate, and in actualfact, its worth noting that congress has not passed a long term funding bill for amtrak since 2008 and has relied relief repeatedly on short term extensions of existing funding levels. And, indeed, the Trump Administration proposed cutting by 13 the allocation of funds for amtrak. President trump has now come up amtrak. President trump has now come up with this very big infrastructure plan, 1 trillion in total but it is not clear how much, if any of it, will be earmarked for improving the railroads, the safety of the railroads, the safety of the railroads and so on, so the debate is filling out. The name macedonia. Thh lhthht thihh hh hhh lhhhhfhhhihh i at the united nations. Greece objects because it has a region called macedonia, and argues the use by its neighbour implies it has claims over the province. Re election has been won in the second term in the president ial elections in cyprus. The conservative incumbent got 55 of the vote and has promised to restart his talks with Turkish Cypriots who govern the north of the island. Police in fraud have arrested a man who is alleged to have made threats to kidnap the singer lana del rey. Michael hunt faces charges of aggravated stalking with a credible threat and an attempted kidnapping with a weapon. The uk home secretary has played down government internal divisions over brexit at the start ofa divisions over brexit at the start of a crucial week in negotiations. Amber rudd said the cabinet was more divided than people thought. Michel barnier will be in london shortly for talks and the uk Brexit Committee will meet later this week seeking agreement on the way forward. Eleanor garnier reports. I have a surprise for the brexiteers. The committee is more united than they think. We meet in the committee, privately for discussions, and i think we will arrive at something which suits us all. Exactly how we trade with the eu after brexit is the source of division in the tories. Some want com plete division in the tories. Some want complete disentanglement from brussels but others hope to stay as close to the eu as possible. The home secretary believes that the government priorities are clear. We wa nt government priorities are clear. We want fiction frictionless trade at the border and make sure there is no border on the island of ireland and we want to make sure we can do trade deals outside the european union. That is the deal we are looking for. It is clear to all in the conservative party how difficult it will be to get everyone on side. There are inherent tensions in brexit because different people take different views. Its notjust in the conservative or labour party, its across the country and we need a team effort, loud and clear. So far the Prime Minister has prevented the decade old split in the conservative party over europe from spilling out into something more serious, something which could spell a crisis for her government. But with crucial ministerial meetings meetings this week to pin down and agreed position on the future relationship with the eu, theresa may will finally have to pick a path, and whichever she chooses, she risks making a large swathe of her party unhappy. It is notjust a battle at home, winning in brussels is also key, and with more negotiations with the eu this week, the next few days could be pivotal for the Prime Minister. China is accusing the United States of exaggerating beijings nuclear strength, saying America Needs to ditch what it calls a cold war mentality. The statement comes after washington unveiled a new nuclear policy, which included plans to diversify its nuclear armoury with smaller bombs. The policy also highlighted concerns about russia and north korea. The Chinese DefenceMinistry Said the us had engaged in presumptuous speculation about beijings intentions. With me is elizabeth minor an advisor at article 36, a member of the International Campaign to abolish Nuclear Weapons. What is your reaction to what the us has announced with its policy change . As you were saying, china is saying that this represents a cold war mentality we think the risk from Nuclear Weapons never went away since the cold war so this policy represents a kind of Reckless Development on what was already a dangerous status quo. You think it rejuvenates the of having Nuclear Weapons rather than rejuvenating it . The Nuclear Weapons they think should be more usable and they should be more usable and they should be more willing and able to use them and there is a proposal that low yield Nuclear Weapons should be more available but the low yield weapons they are talking about are similar size to the bombs dropped on hiroshima in nagasaki to such horrific effect in 19115. We think that any policy that makes these more usable is poor. The us is talking about the deterrent factor, it is saying that countries like russia see the bombs that the us have as too big to be used so they are not, in effect, a deterrent. The mentality that needs addressing is that some states see Nuclear Weapons asa that some states see Nuclear Weapons as a legitimate tool of statecraft, including the trump doctrine that came out, but also states like china and britain and the majority of the world countries are already challenging this through a new treaty on the prohibition of Nuclear Weapons that was in the un and adopted, so only through these kind of routes can we create conditions for multilateral disarmament to be possible. Is this the right time to be thinking about disarmament when we see Nuclear North Korea becomes close to being a Nuclear Power . Why should the world scale back at a critical time . As your viewers know very well there has been dangerous escalation in the region over the past year and new policies like the Trump Nuclear doctrine, we do not see how these can dampen that down in the short term but we are talking about Long Term Solutions to set the stage for addressing the danger of Nuclear Weapons. In a for addressing the danger of Nuclear Weapons. 1 a sense, for addressing the danger of Nuclear Weapons. In a sense, do the powers that have Nuclear Weapons have a chance when you see what a country like north korea is doing . What we need to do is create a Global Environment in which the weapons are not seen as legitimate any more. Can you do that with north korea . M you do that with north korea . If you look at the other weapons of mass destruction, thereafter you countries who would argue today that it would be legitimate to have arsenals of them. It might surprise people to know that the Margaret Thatcher cabinet was looking at asking nato to adopt a chemical deterrent which would not be seen as right now. We have to do the same Nuclear Weapons which affects all states and this is why the treaty is important, not just to states and this is why the treaty is important, notjust to address the short term situation, but longer term to make the world safe from these weapons.

South africas president jacob zuma comes under further pressure as top anc officials try to persuade him to stand down. Lets get a sports update now from gavin ramjauin at the bbc sport centre. Lets start with the premier league. Because there was a sensational finish to the match between liverpool and tottenham at anfield. Spurs scored a penalty with virtually the last kick of the match to earn a point. Harry kane scored it to notch his 100th premier league goal. Earlier Mohammed Salah had given liverpool the lead , before a fantastic Victor Wanyama strike pulled it back to 1 1. Kane then missed a penalty which would have put spurs ahead. Salah then put liverpool in front in stoppage time, before spurs were then awarded a controversial penalty which kane converted. I dont understand both of them. They were both clearly offside. He was clearly offside, and from our position that he was offside but it seems it was not mclear. The second penalty, the referee and the assistant say afterwards that there isa assistant say afterwards that there is a torch, a little such, but we all know he wants that touch and he wa nts to all know he wants that touch and he wants to go down. A little touch. Earlier on sunday, Crystal Palace drew 1 1 with newcastle. Mohamed diame gave the magpies the lead midway through the first half, but Luka Milivojevic levelled from the penalty spot in the 55th minute. Rafa benitezs side are only one point above the relegation zone. Barcelona salavaged a draw against espanyol in la liga. Gerard moreno had put the home side ahead in the second half and espanyol looked to be heading for a big win over their city rivals. But gerard pique rescued a point for the league leaders, with seven minutes of normal time left. It means barcelona, at the time, extended their lead to 12 points. Elsewhere in la liga, girona beat athletic bilbao 2 0. Christian stuani with both goals. And in the game clash between high flyers atletico madrid, and valencia the score is 1 0. Both will stay second and third respectively. Gonzalo higuain scored a hattrick asjuventus thrashed sassuolo 7 0 at the Allianz Stadium alex sandro got the hosts going with a goal in the opening 10 minutes of the game, that was followed by two in three minutes from sami khedira. Anotherfrom Miralem Pjanic saw them 4 0 up at half time with higuain scoring a hattrick in just 20 minutes after the break. Napoli hoping to move back above juventus, at the top with a win. Defending six nations champions england have got their 2018 campaign off to a winning start. Theyve beaten italy 46 15 in rome. England only had a seven point advantage at half time, but their power shone through in the second half. They ran in seven tries in total. Anthony watson and debutant sam simmonds each scored two tries. Very good, very positive and the first game is always difficult. Italy are always traditionally a difficult opponent and they played very well today. Well coached by their coach and may have good Young Players coming through. To have the bonus point and then go on and win bya bonus point and then go on and win by a substantial score was positive for us. It hardly seems credible that Petra Kvitova is back winning wta titles. Just over 13 months after suffering terrible injuries to her left hand, trying to defend herself against an intruder in her own home. Well, kvitova entered the St Petersburg open in russia, as a wildcard but needed just 65 minutes to see off Kristina Mladenovic in the final. She certainly seems to have put a disappointing first round exit at the Australian Open behind her, and is now up to 21 in the world rankings. And thats all the sport for now. Lets stay with sport because sunday is the biggest night in the american football calendar. But fans heading to the 52nd super bowl in minneapolis will be wrapping up warm.

Another incredible season for them. Another incredible season for them. A lot of people thought they would not make it but they keep finding a way to do it. The combination of Bill Belichick can tom brady for over the last 15 years has been phenomenal and this year has been no different. New england is new england but philadelphia was also the number one seed may have been through a bunch of obstacles to get to they are. There was the frontrunner to be the mvp in the league, and pay him to get injured and philadelphia to keep honor roll shows that they have good coaching and players and it shows the character of their football team. Darkest hour has been nominated for six baftas. The make up team that transformed gary oldman into the Prime Minister is hoping to win an academy award. Brennan nicholls has been to meet one of them. You cannot reason with the tiger when your head is in its mouth. Gary oldmans performance in darkest hour has already earned him many accolades and critical acclaim. Turning him, though, into britains wartime Prime Minister has been hailed as a masterpiece of make up. Gary would come into the bus, we would shave his head, apply the make up, takes just over three hours to apply the make up and the wig, plus including getting into his fat suit and costume, close to four hours for the entire thing. He would then go to set for ten, 12 hours a day filming and we need to be there the whole time to maintain his make up throughout that. He would then have his make up removed which takes an hour. And then, once he goes, lucy and i stay for another hour or two. Gary oldman convinced Kazuhiro Tsuji to come out of retirement to design the churchill make up. He had just been working with david on another movie, it was oldman who asked him to be onset applying it alongside colleague lucy sibbick and its the three of them that have been nominated for the oscar. Extremely proud. The bestjob i have done so far to date and i am just so pleased it is getting the recognition it deserves because of the amount of effort myself, kazuhiro and lucy have put into it and the people behind the scenes, such a big team involved. We are getting the credit and our names are on the award, but the amount of people in the workshops involved is amazing. We are to receive our reward. The 39 year old make up artist has a cv full of blockbusters to his name, but this is his first ever oscar nomination. But look at the texture here, the colour. Spending a bit more time prepping, that is why the day was so long, i wanted to make sure i painted all of it perfectly so that they match every day. David flies out to los angeles for the oscar nomination lunch this weekend. Then back for the baftas, before heading off to la again for the oscars themselves on the 11th of march for what could be his finest hour.

Snow showers in parts of lincolnshire, east anglia and the south east. Very hit and miss so some of us might get a dusting and others will get nothing. Many across northern and Western Areas will be clear with frost on the way tonight, so a chilly morning. Lets look at the south east again, and kent, sussex, essex, possibly greater london, this is where we could catch snow flurries in the morning. This unfortunately will coincide with rush hour or even just before the rush hour, but these are snow showers, only five miles across, almost like throwing a dart, some will get it, some wont. Further wintry showers along the north sea coast and across the uk it mainly starts bright and cold with a frost expected. A chilly day on the way with the best of the sunshine across many northern and Western Areas and a Beautiful Day for glasgow and edinburgh and also sunshine expected in plymouth but across central and eastern areas it will be cloud coming through, a breeze and some chances of wintry showers through the afternoon. This weather front is going to move into the cold air during the course of monday night and watch what happens, a spell of snow in scotland, Northern Ireland and the north west of england. We dont think much, maybe ten centimetres across the hills and a couple of centimetres in towns and cities and by the middle of tuesday, you see, in the afternoon, that is where the front will it have effectively snowed itself out and the temperatures will drop rapidly through the night. Frosty wednesday or tuesday night on the way. Wednesday sees as between weather systems so a brighter window of weather with some sunshine around, but on thursday things will cloud over and turn that little bit less cold. Here is a summary for the week, pretty cold, widespread frost at night and some snow as well. This is bbc world news, the headlines.
