last night it was lady gaga who was centre—stage, and she kicked off her super bowl half—time show with god bless america, a patriotic song written by a jewish immigrant. she didn't make an explicit political statement, but was this high—profile hillary clinton supporter sending a message to donald trump? super bowl li! welcome to america. you're not wanted here. go back home. even the adverts last night seemed loaded. this pro—immigration message from budweiser depicted the arrival of one of the company's founders from germany. it has prompted calls for a boycott from some trump supporters. this is the beer we drink... corporate america has also weighed in on the travel ban. around 100 major technology firms, including apple, google and facebook, have filed a legal brief arguing it would make it more

difficult to recruit employees. american arrivals halls, for now, remain places of family reunions. and immigrants from the mainly—muslim countries hit by the travel ban continue to enter the country, knowing the door opened by the legal challenge to the executive order could soon be shut, if appealsjudges side with president trump. thank you for every single person who tried to help me bring my kids back. i'm so happy, i'm so glad, and this is america. america is for everybody, for everybody. thank you, thank you, thank you. the question at the centre of this legal showdown has huge implications. just how much power does the president wield in deciding who comes to this country? nick bryant, bbc news, washington. the bbc‘s richard lister is in washington. he told me why this court case will have long—term implications. i think the next few days

are going to show even more twists and turns, because this appeal court isn't the end of the road by a long shot. what it will do is hear arguments from both sides. they will each get 30 minutes to present their case to the three judges on this appeals court, and then the appeals court will rule. when they decide to make that judgement is up to them, but they have shown that they want to move forward very quickly on this, so i think thejudgement could come within days, potentially even hours, after they've heard from the two sides. it's almost certain that the side that loses in that court case at the appeals court will almost certainly then want to take the case on to the supreme court, which of course has the final say in these matters. so this is one step in the road, probably this week. there will be more twists and turns to come. this is a ready important battle for president donald trump. tell us why. it is. really, what we're seeing now

is the courts defining the limits of his presidential authority. president trump, of course, is but one arm of the american government. there are three. congress is also another arm, and then the judiciary is another arm. now, the judiciary doesn't make the laws in the us, but what it does do is keep an eye on the other two, congress and the president, to ensure what they do doesn't breach the boundaries of the constitution. so that is really what's at stake here. and then whatever, finally, the courts decide in this case so this is really about the next well, it is, and potentially the next eight years, if he's re—elected. and of course, all presidents have these battles with the supreme court. they all try and get as much done as they can, within what they see as the limits of their power. barack obama, when he tried to get immigration reform through congress, and failed, he tried to implement some of those reforms through executive order.

that was blocked in the courts in exactly the same way. george bush also had problems as well. so this is something that happens in more or less every presidency. president trump is not the first. but what is quite unusual is that this should be happening so quickly in his term. earlier, doris messiner, who heads the us immigration programme at the think tank the migration policy institute, gave her thoughts on the travel ban. the ban was introduced without the proper co—ordination with the agencies that are needed to implement it, and it was done very quickly, without the best legal advice and without the best operational advice, on how to implement it. i actually have never worked in the white house myself. i've worked in thejustice department, and i've been the head of our immigration service, which is responsible for implementing an order like this, and it takes an enormous amount

of effort, and certainly requires some advanced notice in order to do effectively this, if one is to do it. why was this done in the way it was? i don't know. i can only say what it is that we observe, and are experiencing and that is that it's a very new presidency, and a presidency that is devoted right now to very quickly delivering on campaign promises. there is just a skeletal staff in the white house, and the relationships between the new advisors in the white house and the career civil servants and new appointees that are coming in to run the cabinet departments that need to implement these policies, none of those relationships have really been developed and built effectively, in a way that's required to do something like this.

so essentially is what you are saying that perhaps the legal steps that we are seeing now may not have taken place if it had happened more slowly and steadily to begin with. yes. donald trump is not the first president to try to limit different types of people coming into the country, is he? well, the president does have very broad authority under us immigration law, to prevent people from coming if they are coming to the united states and it would be detrimental to the interests of the united states. that is the language in the statute. that is an authority that has been in our immigration laws for more than 50 years.

but it has been used very sparingly, it has never been used in a sweeping fashion like this, and it has been used when there has been real provocation, a real danger. probably the most recent, dramatic example was after the 9/11 attacks. this is the first time that authority has been used just to use the authority. i mean, where does donald trump go, if things don't go his way with this appeal, just briefly? well, it's in the courts now, and we'll perhaps know as soon as tomorrow, when a critical hearing takes place, whether this stopping of the order will be continued. if the courts stop the executive branch, then it can't go into effect or it can redraft the order in a way that is consistent with the legal ruling. so, until we get the legal ruling,

we don't really know. but it could go either way. in other news: thousands of people were executed over a period of five years at a syrian military prison, according to amnesty international. its report is based on the testimony of more than 80 former prisoners and guards at the jail, near the capital, damascus. it also includes allegations of torture, which the syrian government denies. the israeli parliament has passed a law legalising some 4,000 homes forjewish settlers built on privately—owned palestinian land in the west bank. the former owners will get compensation, but palestinian groups say the move is legalised theft, and destroys any chance for a political agreement. hundreds of people have taken to the streets in paris to demonstrate, after a young black man was allegedly raped while being arrested last week. 0ne police officer has been charged with rape, and three others with assault. the officers have denied the allegations, and say

they were targeting drug dealers. the victim was treated for severe injuries in hospital. the centre—right french presidential candidate francois fillon, is fighting to stay in the race, after admitting he made a mistake employing family members for parliamentary work. but he said the salary he paid his wife was entirely justified and legal. sarah corker reports. this was francois fillon‘s fightback, after weeks of allegations which he strongly denies. this news conference was an attempt to get his path to the presidency back on track. translation: being courageous in politics means admitting your mistakes. using your family members as parliamentary assistants is a perfectly legal practice, but what was acceptable in the past is no longer acceptable. mr fillon‘s popularity has plummeted since allegations his british wife, penelope fillon, was paid more

than 800,000 euros as his assistant, for work she may never have done. and jobs done by his two children are also being investigated. he said he made a mistake, but also said his wife's salary was justified. but, in 2007, penelope fillon gave an interview to a british newspaper, the daily telegraph, in which she said: and on monday, mr fillon was asked about that interview. translation: when she made that statement, it was picked up by a programme which knowingly took bits of a sentence out of context. it was in english, it was for an english audience, and the focus of the interview was actually, "i will not be cherie blair. " the journalist who did the interview actually got in touch with my wife to tell her how shocked she was at the use of those bits of the interview.

the journalist who did the interview, though, tweeted this. polls are now showing mr fillon is lagging behind his opponents, independent centrist emmanuel macron, a former investment banker and the national front leader, marine le pen. and, with the election 11 weeks away, mr fillon insisted he would stay in the race. sarah corker, bbc news. romania's government is rejecting calls to resign. that is despite seven days of massive street protests, which forced it to scrap proposed changes in the law on corruption. thousands of demonstrators are still on the streets, as nick thorpe reports from bucharest. day seven of the protests here in romania, and i can tell

you they're much smaller than they have been until now. that is partly because people are resting after mass protests, more than 500,000 people here in the square. also because the organisers say the next big gathering should be on thursday. so what will the government do now? they've made clear that although they have been forced to revoke the decree, they still stand by their central argument that the prosecutors in romanian are too powerful, and need to be reigned in. that makes people here in the square very angry. in fact, they say that the whole issue, the handling of the issue, by the government has been so bad that the government should now resign. nick thorpe, bbc news, bucharest. stay with us on bbc news, still to come: the speaker of the house of commons, sends an uncompromising message to president trump about his state visit to britain, later this year. this is the moment that millions in iran had been waiting for. after his long years in exile, the first hesitant steps of

on people from seven mainly muslim countries. french presidential candidate francois fillon apologises for employing his wife as a parliamentary advisor after claims he paid her for a non—existentjob. here in the uk, the speaker of the lower house of parliament says he would oppose plans for president trump to address both mps and lords when he makes his state visit to britain. mr bercow said his concerns followed mr trump's decision to impose his travel ban. 0ur chief political correspondent vicki young has the story. it's an honour that's been bestowed on popes and presidents, a speech to both houses of parliament in the splendour of westminster hall was part of the itinerary for these dignitaries when they visited britain. but the same invite may not be coming president trump's way. in an astonishing intervention, the commons speaker said recent decisions by the president had made him uneasy about issuing an invitation.

i feel very strongly that our opposition to racism and to sexism and our support for equality before the law and an independent judiciary are hugely important considerations in the house of commons. rare applause from snp and labour mps who have been highly critical of the american president. donald trump has got to go! and that anger brought anti—trump demonstrations to the prime minister's door after she invited him on a state visit later this year. for us to roll out the red carpet at buckingham palace or to invite him here to speak to us in a grand occasion at both houses send out all the wrong messages. that's why the speaker has called it right today. the speaker of the commons is a powerful figure who has a say in who addresses mps. he's independent of party politics and is supposed to represent the whole house.

tonight it's clear that some are unhappy with his outburst. i think the speaker of the house of commons should be neutral. to express his opinion in the way he did today, if he values this great office, is insulting to president trump. generally the speaker is meant to referee all of this and should keep himself above that, so that is to be regretted. but it's a symptom of the controversy around this visit. the prime minister has been trying to forge a close partnership with the new pm in washington, saying today that government should engage patiently and constructively with his administration. while theresa may has launched a charm offensive towards president trump, john bercow suggested he is unfit to come here and speak to and peers. many agree with the speaker, saying he is simply upholding the values of parliament, but others think he has completely overstepped the mark. i invite you, mr president, to address us. and tory mps are pointing out that he has in the past welcomed leaders to parliament whose values

britain doesn't always share. vicki young, bbc news, westminster. a pr company representing david beckham has confirmed to the bbc it was subject to a blackmail attempt by hackers threatening to leak his personal e—mails. a british newspaper, the daily mirror, says the private messages were published after the firm refused to hand over a six figure sum. a spokesman for david beckham says that the e—mails were tampered with and deliberately inaccurate. 0ur media editor amol rajan has the story. since hanging up his boots, david beckham's public profile has been largely about charity work, including his role as a unicef ambassador. after playing a key role in the london 2012 games, he wasn't the only person who thought he might be knighted the following year. now hacked e—mails appear to show his anger. it is claimed that david beckham wrote to his pr representative: and:

beckham's team say the e—mails have been doctored. some of this morning's papers were unsparing in their headlines, giving brand beckham a battering. i think most people felt that he did deserve a knighthood. but the daily mirror, which has worked with him on charity projects, lea pt to beckham's defence. i can't really see what david beckham's done wrong. he clearly was upset about not receiving a knighthood, but then the whole of the media predicted that he would get one. he worked very hard to bring the olympics to london. and he works incredibly hard for charity. newspapers used to determine the public narrative about the likes of beckham. but social media has changed the game. now celebrities can use new digital platforms to speak directly to the public and try to manage their own image. over the weekend, david beckham's son posted this intimate photograph on instagram, perhaps

with his father's approval. alan edwards is one of britain's leading pr executives. he worked closely with beckham for over a decade. i think it's really an ebb and a flow. david's had wonderful publicity for a very long time, and i guess this is a moment, it's the laws of the universe. but i'm sure he'll sail through it. to undo any damage. amol rajan, bbc news. cameroon‘s football team have returned home to a hero's welcome after winning the

africa cup of nations. they were met by crowds right from the plane. with their captain, benjamin moukandjo, holding the trophy as they paraded through the streets of the capital yaounde. as you can see they were embraced by some very happy supporters. final preparations are being made for the largest—ever exhibition of art by david hockney, one of britain's most influential artists. it opens to the public at tate britain in london this week and it features more than 250 pieces, including paintings, drawings, photos and videos, tracing his work from his student days in the 1960s. david hockney has been talking to our arts editor will gompertz. it's all about looking. how do we see? do we see like photographs? no, we don't, i don't think. photographs see geometrically. we must see psychologically, mustn't we? do you recognise the artist from these early years,

with the artist today? yes. yes, i do. yeah. i mean, when i'm painting i always think i'm 30. did you ever feel under pressure during your career to have a different style, to not do figurative work? well, i neverfelt pressure, no. i always did what i wanted to do. that's what i've done every day of those 64 years. i've done what i wanted to do every day. can you pick a work out which you are less pleased with? one in the exhibition where you go, "that was maybe not my finest hour"? not my finest hour? in your opinion. i don't think there's any in the show that i would say are absolutely terrible. i mean, i'm not

saying i'm that good. but i'm not that terrible either. what makes a good picture? we don't know, because if we knew there'd be a lot more memorable pictures, wouldn't there? and there aren't that many. and i've done a few memorable pictures. i know this now. when you were painting the biggest splash or any of those very famous images, you didn't know at the time that these were going to have the potency that they... no, no. i didn't know. in fact, you're always a little bit baffled why. all artists, especially if they're painters, have to take on art history. it's a challenge. do you feel you have successfully done that and earned a place among the greats? well i think i've...

i think i have done that. i think i've achieved something here. i think so. the queen has become the first british monarch to reach a sapphire jubilee, marking 65 years on the throne. a portrait of her majesty, taken a few years ago by british photographer david bailey, has been re—issued for the anniversary. and to mark the occasion there was a 41—gun salute in london's green park and other salutes around the country. the queen spent the anniversary of her accession, as she does every year, at sandringham in norfolk. that is it from us for the moment. and you can get in touch with me and most of the team on twitter. hello.

monday turned out to be quite a day of weather across some parts of the british isles with a combination of wind and rain and some hill snow for the northern parts as well. tuesday, a chilly start wherever you may be. there will still will be some of that monday rain, if you like, lingering, especially across the eastern side of both scotland and england, because that weather front will make very, very slow progress through the day into the north sea, and that keeps that chance of a little bit of rain still there across those eastern parts. where the skies clear further west, it'll be a really cold start, there will be some ice around south—western scotland, northern ireland, maybe some sheltered spots across the western side of both england and wales. here, the skies will have cleared for some overnight, and that will give rise to some sunshine first up across the south—west and into wales but you'll notice there are showers not very far away. move a little bit further east from that, this is where we get into that murky zone all the way from central southern england,

through the midlands to northern england and southern parts of scotland. further east again, there the rain from that old weather front. across western parts of scotland and western parts of northern ireland initially, this is where we are going to see some pretty hefty showers, at times, just merging together to give some longer spells of rain with the chance, i would have thought, of a little bit of hill snow yet again. 0n through the course of the day, those showers really getting going across parts of wales and the south—west, you might even hear the odd rumble of thunder in the mix there. i think improving conditions gradually getting into central southern england and maybe the north—west of england, south—western scotland. and relatively speaking, compared to what's to come, those temperatures not too bad. nine or 10 degrees across western parts but underneath the cloud and rain in the east around six degrees. as far ahead as wednesday, that weather front is still lurking. it is heading back towards the west, wouldn't you just know it, not the same intensity i suspect than we've seen of late and that is going to open the door eventually to some cold air, which, as we get on through thursday and into friday, absolutely wins out, such that cold air comes to sit

across the british isles in the latter part of the week with the mild air lurking out in the atlantic. and this is the difference it makes to the temperatures. no longer eight, nine and ten. it's three, four, five and six for many of us with only the western fringes pushing towards seven or eight degrees. a lot of cloud around. i'm afriad it is going to be fairly leaden skies and that cooling process continues apace on into thursday, two, three, four, five or six degrees so that by the end of the week there will be cold easterly wind with a lot of cloud and the odd snow flurry too. the headlines on bbc news: the united statesjustice department has formally lodged an appeal against the suspension of donald trump's ban on citizens from seven mainly—muslim countries. a federal appeals court in san francisco will begin hearing the case on tuesday. the french presidential candidate francois fillon has apologised for employing his wife as a parliamentary advisor. he is facing an investigation over claims she was paid for a non—existentjob. mr fillon insists he did nothing

illegal, and that his campaign will continue. a pr company representing david beckham has told the bbc it was subject to a blackmail attempt by hackers threatening to leak his personal e—mails. a spokesman for david beckham says the e—mails were tampered with, and are deliberately inaccurate. time now for reporters.
