an executive order to withdraw the united states. chips ahoy! samsung's microchip business powers the company to a jump in profits despite galaxy note 7 disaster. in the next few hours, the uk's supreme court is going to deliver its ruling on whether prime minister theresa may needs parliament's authority to start the process of leaving the eu. the government argues ministers can trigger article 50 and begin formal brexit negotiations, because they have the power to withdraw from treaties. but opponents argue only parliament can remove people's rights. as chris mason explains, the ruling is complex and far—reaching. the european union ignites strong passions. almost seven weeks ago protesters gathered outside the supreme court as the 11 most senior judges in the land gathered inside.

hour after hour of dense legal argument followed on the biggest question in politics, where does power lie? is it behind the door here in downing street? or inside here in downing street? or inside here in downing street? or inside here in parliament? the prime minister says she can start the uk's divorce from the eu herself, but campaigners, led by the businesswoman gena miller, say mps and peers have to have a say first. this morning we'll find out who's one. if the government loses they'll also lose complete control of the timetable for starting the process of leaving the european union. so it will have to rush its plan through parliament in the next few weeks. todayis parliament in the next few weeks. today is not about whether brexit should or will happen, but who gets to press go. that is why it matters and that is why there is a lot of interest here in what the judges

have to say. chris mason, bbc news, at westminster. president trump continues to deliver on his election promises and dismantle barack obama's legacy. after weakening obamacare in one of his first actions as the new american president, he's now pulled the united states out of the trans—pacific partnership, the giant free trade deal which covers more than a third of the global economy. he's also said he will impose a border tax on american companies that move jobs overseas and then seek to import goods. from washington, david willis reports. withdrawal of the united states from the trans—pacific partnership. with that and a stroke of the pen, donald trump made good on a campaign promise to pull america out of the trans—pacific partnership. a symbolic gesture given that the deal negotiated by the obama administration had yet to receive congressional approval. great thing for the american worker what wejust did. but it was nonetheless a reinforcement of the president's campaign trail commitment to put americanjobs first. the 12—nation tpp, which does not

include china, was seen as a curb on chinese influence in the region. america's withdrawal may therefore have the effect of distancing the us from its asian allies, but mr trump believes the future lies in one—on—one trade deals with individual countries as a means of achieving terms more favourable to the us. the white house press secretary sean spicer. this executive action ushers in a new era of us trade policy in which the trump administration will pursue bilateral trade opportunities with allies around the globe. this is a strong signal the trump administration wants free and fair trade throughout the world. president trump also wants to renegotiate the north american free trade agreement between the us, mexico and canada and has talks lined up with the canadian and mexican leaders in the next few weeks. he believes international trade deals have hurt the usjobs market. although economists believe more

jobs are being lost to automation than to unfavourable trade agreements. at a gathering of business leaders, mexico's president said his country may now pursue more bilateral agreements. translation: it is clear that the united states has a new vision for its foreign policy. given this reality, mexico is obliged to take action to defend its national interests. neither confrontation or submission. the solution is dialogue and negotiation. president trump also signed an executive order reinstating a controversial ban on us funding for international groups that perform or discuss abortion as a family planning option. mr trump opposes abortion but critics say the move will hinder women in poorer countries who seek access to reproductive health services. david willis, bbc news, washington. australia and new zealand say they believe the trans—pacific

partnership can be salvaged. senior ministers will urge china and other asian nations to sign up to the tpp. they're already calling it the 12 -i agreement. it is possible that us policy could change over time on this, as it has done on other trade deals. there's also the opportunity for the tpp to proceed without the united states and i've this is going to be an active discussions with other leaders as recently as last night with prime minister abe about this. we believe president trump is aware of the importance of free and fair trade. we continue to calmly seek is understanding for the trans—pacific partnership's strategic meaning —— his. the original for countries that came together to consider tpp did so without american involvement. i

guess the question must be for all tpp countries, if america had never asked to be involved in the negotiations, would we have still wa nted negotiations, would we have still wanted to negotiate with each other? the answer to that is probably yes but we'll have to get together in the next month or two and at ministerial level have a conversation to see what steps there may be for us. i don't think tpp is dead but certainly the signal from the us is a very concerning one and it's clear they're not going to be involved. and sally is here with all the business news. interesting to get reaction from countries part of the tpp, some i have spoken to based in asia say they are stronger without the us because they haven't got that strong arm and strong influence steering them perhaps in directions they don't want to go in. interesting to get their reaction from the news of the withdrawal of the us from the tpp. let's remind you what this huge

trade deal was all about and how it was going to work. tpp as its also known is the huge trade deal negotiated under mr trump's predesessor ba rack obama. it was a deal between 12 nations in the pacific area and was set to cover 40% of the world's economic output. the painstaking negotiations were led by obama and took seven years to complete. it was generally seen as a way to cement relations in the area before china could get a foot in. significantly china was not part of the negotiations. the 12 countries signed up to tpp in february of last year but mr obama couldn't get it ratified by the republican held us congress. president trump now wants to negotiate trade deals on a country—to—country basis with a 30 day cancellation clause in case somebody misbehaves. we will be talking more about that

in world business report. we're also looking at samsung again today. profits at korean tech giant samsung electronics have jumped in the fourth quarter to $7.8 billion mainly thanks to its chipmaking and panel display businesses. these outweighed the problems samsung had with its exploding galaxy note 7 smartphones. an official investigation yesterday found the cause was due to bad batteries. but the firm also has other issues to worry about including a corruption probe involving south korea's president park guen hye. all that on samsung and the other

business stories in world business report in 20 minutes. in the meantime i'm back at my desk to look at other things. unaccompanied children as young as eight are among more than 1,000 migrants sleeping rough in the serbian capital belgrade. they're living by the side of a railway line and in abandoned warehouses, with temperatures dropping well below freezing. as our europe correspondent gavin lee reports, serbia is not a member of the european union, where most of the migrants would like to be. this is how migrants are living in the serbian capital, belgrade. sleeping rough with temperatures dropping as low as —13 this week. this is what the dream for migrants coming to europe has turned into for many here in belgrade. there are 1000 people here, mainly afghan men, and this is the q2 survive. there's people living rough, living hand to mouth. one meal a day at 1pm and

this is where they live. to either side of the queue, warehouses by an old train station, disused now, in the worst condition i've seen anywhere on the migrant trail. but the people here have a choice. the serbian government say warmth and food is available in sufficient till macro mack official shelters but many fear deportation and try illegally to cross into hungary and other eu countries. abdulfrom pakistan shows the scars of failed attempts, bitten by police dogs, he says, at the border. this is the alternative. 6000 migrants are housed in official centres across the country waiting for a chance to be among 20 people a day granted asylu m be among 20 people a day granted asylum by hungary. five—year—old zeenat and her family are from afghanistan. she's been learning the languages of the migrant trail, learning how to count in serbian. on

the belgrade streets, eight—year—old as is alone. his older brother detained on the croatian border. aziz, you don't sound well, is he 0k? he is ok, he has a little bit of the flu and chest problems, cough problems. he would at least be safe and warm... extremely ill, we alert aid workers to aziz‘s case, who try to convince him to leave. that's not uncommon sadly, we've seen over the la st uncommon sadly, we've seen over the last few days children that are eight, nine, ten. iwas speaking last few days children that are eight, nine, ten. i was speaking to a 12—year—old afghan boy yesterday in this warehouse who's been here for three months, he's in this warehouse who's been here forthree months, he's waiting in this warehouse who's been here for three months, he's waiting for a call from a smuggler because he thinks that's his best option. with older migrants looking out for him, saying their chance of crossing the border is better with him in tow, three days on aziz is still sleeping rough in the warehouse where there are tens of other unaccompanied

children. gavin lee, bbc news, belgrade. a us senate committee has narrowly approved donald trump's choice for secretary of state, the former chief executive of exxonmobil. members voted along party lines 11—10, clearing the way for rex tillerson‘s confirmation vote by the full senate. our state department correspondent barbara plett usher explains the challenges around his nomination. well, donald trump likes to appoint billionaire businessmen to his cabinet, but the democratic members on this committee weren't convinced an oil executive was the best choice for the nation's top diplomat. they said they were concerned he would continue to view the world through a corporate lens, that he hadn't been convincing enough about the importance of american values in forming foreign policy. that his past business deals could present conflicts of interest. this kind of sharp partisan split is quite unusual when it comes to secretary of state nominees. traditionally they are approved with overwhelming support from both parties. there were a number of republicans who did also oppose mr tillerson,

expressed concerns about his nomination, but eventually they backed down from their challenges. one of the big concerns expressed was mr tillerson‘s past business dealings with the kremlin and questions about whether he was committed to maintaining sanctions on russia over the annexation of crimea. he did oppose those sanctions when he was head of exxon but he said as secretary of state he would represent america's national interests. and mike pompeo a congressman from kansas has been confirmed as the new director of the cia. 53—year—old mr pompeo is a graduate of the west point military academy and served in the gulf war in the early 90s. he's now responsible for the country's world—wide network of spies, and has called russian attempts to influence the presidential election an aggressive action. stay with us on bbc news, still to come: they've got the happiest kids in the world but why? we travel to the netherlands to find out. the shuttle challenger exploded soon after liftoff. there were seven astronauts

on board, one of them a woman school teacher. all of them are believed to have been killed. by the evening, tahrir square, the heart of official cairo, was in the hands of the demonstrators. they were using the word "revolution". the earthquake singled out buildings, and brought them down in seconds. tonight, the search for any survivors has an increasing desperation about it as the hours pass. the new government is firmly in control of the entire republic of uganda. moscow got its first taste of western fast food, as mcdonald's opened their biggest restaurant, in pushkin square. but the hundreds of muscovites who queued up today won't find it cheap, with a big mac costing half the day's wages for the average russian. this is bbc world news.

i'm adnan nawaz. the latest headlines: britain's supreme court is set to make a landmark ruling on who can kick start the brexit process — parliament or the government? more than 1,000 migrants are sleeping rough in temperatures as low as —13 degrees in the serbian capital, belgrade. after four decades in charge of one of the world's richest and popular sports, bernie ecclestone has been dismissed as the boss of formula one. the sport is now in the hands of new owners, liberty media. the american company's $8 billion takeover of the sport is complete, and the american businessman chase carey takes over as chief executive. 86—year—old ecclestone becomes the honorary chairman, but he'll no longer be involved in the day—to—day running of the sport for the first time since the 1970s. his association with f1 has been a lucrative one. the business magazine forbes says he's worth almost $3 billion. the bbc‘s formula one reporter andrew benson gave us his reaction to the takeover, and told us about the role ecclestone has played in growing the sport.

he has been central in building formula one up over the last few decades into one of the biggest sports in the entire world. it is second, third in terms of global audience, i should say, to the football world cup and the olympics. and he has done that through a combination of tv rights and doing deals with governments, the likes of vladimir putin, and so on, and it is hard to overstate, actually, the impact that he has had on growing formula one into that position. the value of the sport is $8 billion, and if you look at the changes they have made today, they have employed some very serious people. first of all it is important to say, although bernie ecclestone has been removed as chief executive officer and doesn't have any actual power anymore, he has been kept on as what they are calling the chairman emeritus, as a kind of adviser. that is a wise move, given the expertise he has. and also a lawyer he worked very close with has also been kept on.

the big headline is ross brawn, the boss of the mercedes team a few years ago, and before that the technical director of ferrari, where michael schumacher was so successful, winning the championship, he has been given a new role overseeing the motor sports side of the liberty business. and sean bratches, an executive who was a big deal in america with the espn network, is taking on the commercial role. so some very serious players underneath chase carey, who himself, the chairman, has been a long—term talent of rupert murdoch. venus williams has become the oldest woman in the open era to reach the semi—finals of the australian open. the 36—year—old american has beaten anastasia pavlychenkova of russia in straight sets. it's a 50th career victory for venus at melbourne park, earning her a spot in the last four for the first time in 1a years. she'll play another american in the semis, coco vandeweghe, who's stunned the reigning french open champion. unseeded vandeweghe has beaten garbine muguruza, 6—4, 6—0.

senegal and tunisia have both qualified for the quarter finals of football's africa cup of nations. senegal had already guaranteed their place in the last eight, but their draw with algeria knocks the north africans out. tunisia beat zimbbwe 4—2, as piers edwards reports from gabon. —— zimbabwe. here in libreville, tunisia raced into the africa cup of nations quarterfinals with a victory over zimbabwe. it looked to be a complex affair. senegal had already won it, but any one of tunisia, zimbabwe or algeria could have gone through. the task, though, was easiest for tunisia, the only one of the challengers to have actually won a game. if they beat the zimbabweans in this stadium behind me, they would book a place in the quarterfinals against burkina faso on saturday. and they swiftly did that, racing into a first—half lead. at half—time, they

led by three goals. in the day's big game, senegal, who had booked their place against cameroon, they rested ten players for the match against algeria. 2—2 it ended in franceville, slimani scoring twice for the algerians. not long ago, algeria were the highest—ranked african team, and they arrived at these finals with many tipping them to win theirfirst finals since 1990. instead, the desert foxes, as they are known, bowed out of this competition without winning a game, and that despite boasting the african footballer of the year, riyad mahrez. britain's double olympic boxing champion nicola adams is turning professional. she's signed a long—term promotional deal with the promoter frank warren. his association with adams comes three months after ireland's 2012 olympic lightweight champion katie taylor began fighting professionally. more from the bbc‘s katie gornall.

i am here eating humble pie today, because i have not been the greatest advocate of women's boxing. as promoter frank warren announced his newest recruit, it felt like a big step forward for british boxing. but then, nicola adams is used to breaking new ground. last year in rio, she became the first briton to successfully defend an olympic boxing title in nearly 100 years. she is also the reigning world, european and commonwealth champion. almost every one of her major fights has ended with that famous smile. as an amateur, she told me she has nothing left to prove. there's a lot of goals in the professional ranks to achieve. becoming a world champion and european champion. so many goals to achieve in the professional ranks, hopefully trying to make women's boxing on par with the men's. the announcement means now giving up the chance to represent team gb. today team gb released a statement, praising her huge contribution to both the olympic programme and the sport of boxing, adding her place

in history is secure. adams follows another olympic champion, katie taylor, into the olympic game. the irish fighter recently featured on the undercard at anthonyjoshua and eric molina's high—profile title fight. she has achieved everything there is to achieve at amateur level. yes. how far do you think she can go as a professional? i think, without a doubt, her pedigree is beyond reproach as a boxer. i think she could probably win a world title now. i'm not sure, but she needs to bed into it. adams will have to wait until april to make her debut in manchester, before a fight in leeds in may. so far she has done everything asked of her. now it is time to see if she can live up to her billing once again. children in the netherlands consistently rank as the happiest in the world. unicef certainly found that to be the case a few years ago when, in the same study, the uk came 16th.

so a british mum who lives in amsterdam and an asian—american who calls herself a reformed tiger mmm are sharing their insights in a book called the happiest kids in the world. what, ifanything, can we learn from the dutch approach to parenting? anna holligan has been finding out. this doesn't take much, according to the dutch. they have got the most contented babies, the happiest kids and as adults the best work—life balance. the lessons start with brea kfast. balance. the lessons start with breakfast. they place a high value on family life, on communication between the members of the family, and so part of eating together is about talking together and the dutch scored the highest on children who ate breakfast before they went to school and that sets them up for the day, so you doesn't matter even if it is chocolate. chocolate sprinkles clearly contradict the healthy eating advice and yet dutch kids have some of the lowest obesity rates which may be linked to the fa ct rates which may be linked to the fact so many cycle to school, but as

you can see bikes and cars have separate lanes, so parents don't have the same worries about sending kids out on two wheels. and when they get to school dutch pupils stonefa ced they get to school dutch pupils stonefaced academic pressure, things like tests and homeworker, until much later. there is not so much pressure, children start school i positive way, by enjoying it, by feeling this is something nice to do, andi feeling this is something nice to do, and i think that last your whole life. that is backed up by the unicef statistics which suggest these children are more likely to go on to further education than their british counterparts. you will see lots of fathers at the school gates. the dutch government legislates for unpaid daddy days which encourage families to share the childcare. and then there is the freedom. it is actually wonderful. and plus, we a lwa ys actually wonderful. and plus, we always read in all of these books, right, that they should play outside, so i am happy to be part of a culture where they are expected to be out and play. is it because in

the netherlands it is safer? we cannot send kids out to pass in london or the heart of birmingham, can we? i think so, actually. london or the heart of birmingham, can we? ithink so, actually. in london or the heart of birmingham, can we? i think so, actually. in a sense, you have to trust your own society right? back to basics parenting is what it is all about. you don't have to try so hard. and the byproduct of giving kids greater independence — more time for yourself, at least, when they are a little older. head due west from here and you will reach essex. the uk may be geographically close by there are fundamental differences between society and not all of the lessons from here can simply be exported over there. but they may just inspire you. don't forget, bbc .com/ news is the website and we are looking at them and's water finals in melbourne is taking place and stanislas wawrinka

is up againstjo—wilfried tsonga. freezing fog is likely to become extensive, so on tuesday morning, similar to monday morning, freezing fog patches could give rise to travel to disruption, to roads and airports, so head online for the latest updates. through the night the fog becomes extensive across england and wales. a bit of a change taking place across scotland and northern ireland with outbreaks of patchy rain. it will be a cold start tuesday morning. watch out for the dense, freezing fog as it really will be quite troublesome for a time through the morning. western fringes of england and wales have more of a breeze, so probably fog free and maybe a little bit of brightness for you through the morning. quite a contrast for scotland and northern ireland, we are starting off the day not on a freezing note but we are actually a little milder

than of late, with more of a breeze, cloud, and outbreaks of rain certainly across the higher ground of western scotland. through the day i think it will stay quite grey, maybe damp waether into western wales and south—west england through the day. for the rest of england and wales, the fog will lift, allowing sunshine to develop, and where it lingers it is going be really cold. quite a contrast to the west with double figures. looking closer to single figures, around freezing where the fog lingers. the fog makes a return once again on wednesday morning certainly for central, east and south—eastern areas, and it might be stubborn or slow to clear and might lift into low cloud, so it could stay quite cold and grey. elsewhere, sunshine, the breeze with thick cloud across scotland and northern ireland. double—figure values here but another cold day i think for much of eastern scotland and england and wales. cold digs in for thursday and we start to pick up a strong south—easterly wind. that is coming off the near continent, which has been freezing for the past few weeks now, this is really cold and dry air. so, although it is dry air, it is going to break up the cloud, so we should see some

sunshine through thursday, particularly through the afternoon. if you add on the wind, it is going to feel really biting. temperature—wise we're looking the low—to—mid single figures, but if you add on the biting wind in some parts of eastern england and the north—east, it is going to feel more like —2 to —5 celsius, so you really need to wrap up. this is bbc world news, the headlines: the uk's supreme court will this morning deliver its long—awaited ruling as to whether prime minister theresa may needs parliament's authority before she can start the process of leaving the eu. president trump has cancelled a massive free trade deal, the tra ns—pacific partnership. it's a decisive shift in america's dealings with the rest of the world. the deal negotiated by the obama administration was never ratified. mr trump said the move was great for the american worker. more than 1,000 migrants, including unaccompanied children as young as eight, are sleeping rough in temperatures as low as —15 degrees in the serbian capital belgrade. bernie ecclestone's four—decade

reign in charge of formula 1 has come to an end. the sport is now in the hands of new owners, the american company
