america will build a wall on the mexican border, says president trump, as he prepares to unveil plans to bolster national security. he's expected to set in motion his election pledge to build the 2,000 mile long wall and explain how it will be paid for. and it's understood he'll sign executive orders to restrict immigration and impose tougher visa regulations on a number of mainly muslim countries. we will have the latest from washington and from mexico. also on the programme this lunchtime.... ican i can confirm to the house that the plan will be set out in a white paper published to this house. a climb—down for the prime minister as theresa may says she will publish her plan for brexit in a white paper for parliament's scrutiny. high heels, make up and revealing clothes — women are experiencing widespread discrimination when it comes to dress codes at work say mps. which one is yours? we report on the rise of the counterfeit industry in china — fakes that are so good even the lego

boss can't tell the difference. this is lego. this is lego, you're telling me? this is not lego. it's trying to be lego, is my assessment of it. out of vogue — after 25 years at the helm, the editor of british vogue, alexandra shulman, says she's stepping down. and coming up in the sport on bbc news... serena williams has backed britain'sjoanna konta to be a future australian open champion — despite knocking her out in the quarter finals in straight sets. good afternoon, and welcome to the bbc news at one. donald trump is promising a "big day" on national security today, as he makes good on his pre—election promises to crack down on immigration, and tighten internal security.

he's expected to give details of how america will build its wall along the border with mexico. he's also expected to halve the number of refugees allowed into the us, and tighten visa controls on visitors from a number of predominantly muslim countries. 0pponents have reacted with alarm to the plans, as david willis now reports from washington. we're going to have our borders nice and strong. we're going to build a wall. build a wall. build a wall! we have to build the wall, folks. it was the soundtrack to donald trump's unorthodox campaign for president — a call to build a wall along america's southern border with mexico. now he seems set to press ahead with measures he believes are vital to stemming the illegal flow of immigrants into the united states. the president on his twitter account said simply: he's vowed to make mexico pay for it what's more,

although the mexican government has refused to do so. translation: we recognise that the united states has a right to build the wall, even though we don't like it. but it's another thing to get a neighbouring country to pay for its construction. we have said many times that this is unacceptable. it's the clear position of the mexican government and the mexican people. later in the week, to round off a busy start to his presidency, mr trump is expected to sign executive orders, closing america's borders to refugees, and limiting access to citizens from seven african and middle eastern countries — countries the administration believes export terrorism. they're mainly muslim countries, but the mantra of the trump administration is "america first". a country that traditionally has opened its doors to immigrants is about to head in the opposite direction. in a moment we'll talk to our correspondent in washington,

but first let's go to will grant in mexico city. the big question is how this school is going to be paid. —— this wall. there is a lot that mexicans may disagree with, but if there is one thing they can rally around it their hatred, their complete rejection of this wall. i bet the body from the top politicians to workers in car factories —— everybody, from the top politicians to ordinary people up and down the country reject this friday and their clear that mexico will not pay for it. that's what they say. this is having a great impact on the popularity of the president here, and wreak a pena nieto, who is due to meet mr trump in washington, dc on the 31st. it has hit him hard, he's facing the lowest popularity figures of any

mexican president for two decades. it is his handling of this particular issue that has hurt him so particular issue that has hurt him so hard. as far as mexicans are concerned, they simply will not be paying for this — either before or after the event, in terms of remittances, some kind of control of taxes, whatever it is that mr trump is proposing, you can be very sure that mexicans will oppose it. thank you. and we can speak to our correspondent in washington, gary 0'donoghue. president trump has promised a lot more detail on national security, but he's also said he will have more detail and but he's also said he will have more detailand an but he's also said he will have more detail and an investigation that he has announced he will launch this morning into voter fraud. it's interesting. donald trump won the election here fair and square under the rules of the constitution, he won 33 states, 306 electoral votes, but he didn't win the popular vote. hillary clinton got 3 million more votes tha n hillary clinton got 3 million more votes than him countrywide, and he doesn't like it one bit. several times he said that there has been

voterfraud. he is now announced this investigation. there is no evidence of voter fraud on anything like that scale. i think his aides will be pulling their hair out this morning because this kind of thing is likely to overshadow what should bea is likely to overshadow what should be a very big day for him in terms of fulfilling one of his promises — the wall. plus those other measures on immigration. we are looking at a potential temporary ban on refugees coming into the united states. 85,000 came in last year. that will have a huge impact worldwide. and again these huge views of restrictions on seven countries from north africa and the middle east, pending the imposition on what they are going to call in the long run "extreme vetting." that could all be subject to legal challenge, particularly because they are predominantly muslim country. the lawyers could say it is discriminating on religious grounds and that is unconstitutional. thank you, both. and you can get much more on these first days of the trump presidency.

that's 100 days with katty kay in washington, and christian fraser in london at 19:00 tonight. the prime minister has backed down in the commons after pressure to publish the uk's plans on how the uk will leave the european union. theresa may now says the government will publish a formal white paper for scrutiny. she had been under pressure from labour mps and a number of conservatives to produce a policy document. it will be separate from the legislation mps will vote on, which would trigger the process of leaving the eu. a bizarre political correspondent. —— here is our political correspondent. off to the commons. yesterday a supreme court ruled against the prime minister, forcing her to consult parliament before starting formal brexit negotiations. that wasn't enough for some mps who complained about the lack of a clear

vision of the government's plans. 0rder, questions to the prime minister. but today she sought to seize the initiative with an unexpected announcement. ican announcement. i can confirm to the house that our plan will be set out in a white paper. a white paper, formerly setting up the government's approach, was a central demand of the opposition. the labour leaders struggle to rethink his attack. because we know when this like paper is going to be available to us —— could we know when this white paper is going to be available to us and why it's taken so long to get a? theresa may said the timing was less important than negotiating a good deal. cand deal. c and others asked for a white paper. i've been clear there will be a white paper. what i'm also clear about is that the right honourable gentleman always ask about process. about the means to the end. i miss government focusing on the outcomes. with focusing... —— i and this

government. jeremy corbyn was determined that it would mean cutting taxes on big business. will she offer some clarity and some certainty and withdraw the threat to destroy the social sector —— structure of this country by turning us structure of this country by turning us into the bargain basement she clearly threatens? tomorrow the government will publish the deal to get parliament's improvement for starting formal brexit negotiations. ministers are confident they can get it through without significant setbacks. but long and complex battles lie ahead. let's speak to our assistant poltiical editor, norman smith. how big a climb—down is this for the prime minister? well, make no mistake, it is a climb—down because downing street have repeatedly rebuffed the idea of publishing a white paper. i was speaking to some of mrs may's people this morning and they said they would not publish a white paper because if they get mps out they will move onto demanding something else. and in the commons

mrs may gets up and says, we are going to publish. but it strikes me as quite a crafty climb—down because politically this is a concession mrs may was perhaps always planning to make. because governments almost a lwa ys make. because governments almost always published a white paper before they going to negotiations about other eu treaties. so she may a lwa ys about other eu treaties. so she may always have intended to do this. and you sense that for many conservatives, this will keep them on board. because there were a group of tory mps poised to side with opposition politicians to vote against mrs may and demanded white paper. so she has defused that and wrong—footed jeremy corbyn, who lined up in the commons to ask her a whole are critical questions about the white paper. he was left somewhat trying to find his way. so, yes, it's the climb—down. but it's

quite a clever climb—down. and one which mrs may must always have intended to make. 0ne which mrs may must always have intended to make. one other thing to say, in the last few minutes we've been told by downing street that the bill to trigger article 50 will be published tomorrow. that is going to be the next focus of possible argy—bargy over brexit, as mps look at that and decide what sort of amendments they want to table. so thatis amendments they want to table. so that is going to be the next big bust up over brexit. thank you. a man has been arrested in connection with alleged threats against the campaigner gina miller, who led the brexit court case against the government. the 50—year—old man was arrested in london's knightsbridge this morning. our legal correspondent, clive coleman, is here. what more can you tell us? officers from the met‘s anti—cyber crime unit, 0peration vulcan, the rest of this 50—year—old man this morning in knightsbridge this morning on

suspicion of racially aggravated malicious communication. the arrest is in connection with a complaint made on the 6th of november by gina miller. she's the woman who successfully challenged the government's plans to trigger article 50 of the lisbon treaty without an act of parliament. she won her case at the court yesterday. it relates to threats made online and a second unrelated comment believed to have been made by the same suspect in august 20 16. the arrested man is currently in custody ata arrested man is currently in custody at a central london police station. as pa rt of at a central london police station. as part of the same investigation, we are told that the police issued eight cease and desist notices to various individuals around the uk. they do what they say on the tin. those notices that they if you don't stop the behaviour you're involved with, that could lead to police action. speaking to me in december following the supreme court hearing, gina miller outline the general nature of the threats she has faced. they are quite vile. the sexual violence is very vile and i wouldn't like to say, but anything you can probably

imagine is what i've been threatened with. then there have been particular death threats about slitting my throat, or beheading me, or whatever it is. today's arrest is separate from the arrest by officers from the same met unit in early december, during the supreme court hearing itself, of a 55—year—old man in swindon on suspicion of the same offence. he was released on bail. clive, thank you. david cameron has called for more funding for dementia research as he revealed that he is the new president of the charity alzheimer's research uk. the former prime minister says the focus on alzheimers research lags too far behind that for cancer and strokes. he says he wants to "win the battle of priorities" because dementia shouldn't be written off as "an inevitability of later life". the laws which ban sexist dress rules at work aren't being enforced properly, according to a group of mps. it follows the case of a woman who was sent home from herjob at an accountancy firm for not wearing high heeled shoes,

while the same company had no dress code for men. when mps began to investigate the story, they were inundated with complaints from women with similar experiences. simon gompertz has more. the receptionist who wouldn't give in. nicola thorp refused to wear heels between 2—4 inches high. she kept her flat shoes on, was sent home without pay, and now mps have taken up are caused. the report is great because it doesn'tjust focus on high heels. this was neverjust about a on high heels. this was neverjust abouta pairof on high heels. this was neverjust about a pair of shoes. it's about how women are viewed in the workplace. there's so much pressure on women to notjust look professional, but to look attractive. mps heard from hundreds of women who said they had hurt their backs, wearing crippling pain and thought being forced to wear heels was sexist. now there is a call for awareness campaigns and bigger fines

for employers. it'sjust common for employers. it's just common sense. for employers. it'sjust common sense. if people use their common sense. there are a lot of people wearing flat shoes now, which is the fashion. that's what it should be. you shouldn't have to totter around in high heels if you don't want to. dress codes at work have to comply with health and safety regulation to reduce the risk of injury, and with the equality act which bans dissemination. while there was likely to be differences between the way men and women present themselves, what is applied should be reasonable, which applies to heavy make—up, too. the government says what happened to nicola thorp over high heels was unlawful. but mps have found that the pressure on women is widespread and most would like to see something done about it. you're wearing high heels. have you been forced? definitely not. looking smart is subjective. wearing flat shoes doesn't necessarily make you look not smart. ifi doesn't necessarily make you look not smart. if i feel comfortable in heels, i will. not smart. if i feel comfortable in heels, iwill. but if

not smart. if i feel comfortable in heels, i will. but if i don't, i don't think i have two. it should not be a thing. i think there is a feeling that wearing high heels is more feminine, that it wearing high heels is more feminine, thatitis wearing high heels is more feminine, that it is smarter. i've never been told to wear heels. if you were, what would you do? i would be very, very put off working for that company. the campaign over high heels has highlighted the tyranny some women feel subjected to over their appearance. mps are saying more still needs to be done to make sure they comes into work in the shoes they choose. our top story this lunchtime. donald trump is to unveil his plans to build a wall with mexico, stop refugees entering the us, and tighten visa controls with predominantly muslim countries. and still to come. as the cold snap continues, reports of a sharp rise in the number of people sleeping rough on england's streets. coming up in sport at half—past. liverpool playmaker phillippe coutinho has signed a new five—year contract, worth around £150,000 a week, making him the highest—paid player at the club. china may be one the world's biggest

producers of many of the things we buy, but it's also gaining a reputation as one of the world's biggest producers of fake goods. some of the most famous high street brands are losing out on billions of pounds in trade, because of counterfeiters. their merchandise is often so good, it's impossible to tell the difference between what's real and what's not, as our correspondent in beijing, robin brant, found out when he went to speak to the boss of the toymaker, lego. billions and billions of these little plastic bricks have been sold the world over, and now lego is betting big on china. what started out with hand—cut bricks in denmark in 19119 is now a $100 million state—of—the—art operation near shanghai. but they

are not the only ones doing it. copies like this and fakes or counterfeits are prolific in china. lego is currently suing the firm behind this copycat star wnrs model. so how easy is it to spot the difference? we bought a real one and a copycat and asked the experts. if you have to ask me to guess, i would say this one, maybe. which one do you think is real? you think this one is real. you're right. the truth is, they look and feel almost identical. the copy‘s so good, in fact, that even the boss of that huge new lego factory can't tell. have a little look at that for me. just from there. what do you think of that?

it looks like a mini figure to me. what do you think of him? two men. which one's yours? just have a guess for me. i would say this is lego and this is not. 0k. this is lego. no, this is lego. this is lego. bought from toy‘r'us yesterday, built by my daughter. that's not real. it's not lego. it is trying to be lego, is my assessment of it. lego is not the only foreign firm investing big in china but having trouble with local copycats. land rovers are now made here. white evoques like this sell particulalrly well. but the british firm has been powerless to stop this. tucked away on a shanghai side street, this is a land wind. it's similar on the inside and very, very similar on the outside, but a lot cheaper. this is our copycat that caught people out.

you can buy him and the real thing on the huge online retailer, alibaba. they took down thousands of links to copycat lego products last year alone, but the toy maker is still pursuing manufacturers in the courts because even the boss cannot tell the difference. robin brant, bbc news, shanghai. there's been a big increase in the number of people sleeping rough — with more than half the councils in england recording a rise. 0verall more than 4,000 people a night were sleeping rough last year — a 16% increase on the year before. the homelessness charity crisis says the numbers are going up at an "appalling rate". from birmingham, seema kotecha, sent this report. as the darkness creeps in, the wind chill begins to bite. those who have nowhere to go look for shelter. with outreach worker paul, we come across bob, who has been living on the streets for months. well, i'm used to being alone, i have done that for most of my life, but sometimes

i like a bit of company. someone to talk to. i did have some people who'd used to come and sit here and talk to me. i'd get here about half ten. you're smiling. yeah, i've got virtually everything i need. the number of rough sleepers in england has increased by 16% over the last year. local authority counts and estimates show that in autumnm 2015 there were 3569 rough sleepers. but counts carried out in november last year show that the number has risen to 111311. well as we were walking by pauljust stopped to check up on this rough sleeper over here. he said that he was in a lot of pain. he said he had actually been assaulted in the night. so paul called the paramedics and they're just making sure he's 0k. we think they're probably going to have to take him to hospital because it seems

there is something seriously wrong with him. we were told he was discharged later that day. some charities blame council cuts for putting more vulnerable people on the streets. local authority budgets have been reduced by around 20% over the past six years which they say have led to fewer services. homelessness is affected by austerity, the cuts that have come down from nationally, the cuts to the nhs, local authorities and also those in terms of benefit caps, that has a huge impact on why people are on the streets. birmingham city council are doing a lot to try to reduce this by partnership work, we are working with key agencies, we are doing outreach, surgeries, and we are actually listening to rough sleepers. the government says by 2020 it will have invested more than £500 million on tackling homelessness. but with a further squeeze on council spending expected in april, there are concerns that hostels and shelters could be closed down. forcing more people to live rough. seema kotecha, bbc news, birmingham.

four school children, all under the age of 13, have been taken to hospital after taking cocaine, they thought was sherbet. it happened at broadstone middle school at poole in dorset. 0ur correspondent, duncan kennedy, is there. a strange and potentially very disturbing incident. it happened on january the 3rd although it has only just come to light. what seems to have happened judging from what the police and headteacher said is that the pupil turned up the school, we do not know how old they wear, with white powder. three other children then became involved, they all thought it was sweets but for some reason the alarm is raised, police we re reason the alarm is raised, police were called to the school. also southwest ambulance who turn up and check over the children. the children are sent to hospital as a

precaution, given a check over and sent home and police said there was no suggestion that the children ingested anything. the police are confirming that this was cocaine. we have no further details than that. what the headteacher saying, is that we would like to reassure parents that the incident was dealt with swiftly a nd that the incident was dealt with swiftly and in line with our policies. she went on to say police enquiries are ongoing regarding the incident and as such we are unable to comment any further. so far as dorset police, all we're saying is that a 32—year—old man has been arrested on drugs offences, he has been bailed to appear again in february and their enquiries are continuing. no further details of the moment but those for children involved are said to be safe and well and did not ingest anything although it has been confirmed that this was cocaine. women mps say they're experiencing unprecedented levels of verbal and online abuse. around two thirds said they felt "less safe", following the murder of the labour

mp, jo cox, last summer. some reported death threats, with more than half of those questioned by the bbc saying they had had physical threats. 0ur political correspondent, ellie price, has more. newsreel: it gives me the greatest pleasure to introduce to you the new national unionist women members. it took a long time to get women into parliament. the first female mp to take her seat, nancy astor, was elected 90 years ago. eventually, more would follow. they fought and died to get representation in parliament, but now modern women mps face their own struggle. right, so what you're looking at are tweets, the abusive tweets that my team screen shot—ed. anne mclaughlin mp won't read the abuse she receives online, which is just as well, it's deeply personal. she doesn't really want to share it. it takes a lot of strength not to.

it's very tempting if you're alone at night and nobody can see you if you get upset and you cry, to just have a look. but why would i do that to myself? but it is notjust hurtful insults on social media, there's an even darker side of death threats and violence. jo cox was murdered outside her constituency surgery last june. such threats are of course faced by male members of parliament too, but two thirds of the female mps we spoke to say they have felt less safe ever since. and well over half have received a physical threat from a member of the public. i've had death threats towards myself and my family, one of which the police are investigating. and one where an extremely graphic image of a beheaded corpse was sent to me with the threat that, you know, for the life of myself and my family. i have young children, so i take that extremely seriously. this is the room where i hold my surgeries.

tulip siddique, begrudgingly, now makes sure she has security whenever she holds constituency surgery. you feel safer now? well, this building is a secure building, there is a police presence outside, the staff are very supportive, so i do feel safer here. it's all paints rather a grim picture and certainly the majority of mps we spoke to say they are concerned that hearing about this sort of abuse might put off good new people, good new women, from wanting to become mps. in fact a third of those we heard from said they had considered giving up theirjob here in parliament because of it. and yet, none have. and the majority we heard from say, despite the difficulties, the job is a privilege and well worth the flak. ellie price, bbc news, westminster. she's the editor who persuaded the duchess of cambridge to appear on the front of the centenary edition of vogue, but today alexandra shulman, has said she's stepping down from the job as editor in chief.

she's been in charge for a quarter of a century, but she said she now wanted to "experience a different life". david silitto reports. in the world of high fashion and the catwalk show you know where you stand, by where you sit. for 25 yea rs stand, by where you sit. for 25 years the front row seat of british fashion has belonged to alexandra shulman. in a world all about what is new she has been a constant figure in an era in which british fashion blossomed with names like stella mccartney and alexander mcqueen. i think the white... while british folk has just celebrated its 100th anniversary and is still at the top of the fashion prestige list, it has been a torrid time in the magazine business. 0nline now offers alternative ways for people to get theirfashion

days, it caused a few issues again at the airports and on the road. ca ptu red at the airports and on the road. captured by one of our weather watchers in temperature. the early morning mist has cleared to reveal some sunny skies in nottinghamshire and again we have a mixture of weather today. a slice of sunshine for north and west england and wales. northern ireland and scotland staying mainly cloudy. visibility is slowly picking up across eastern counties of england. when the fog has gone it stays gone which is good news. a fine afternoon for northern counties of england. pretty cloudy across northern ireland with some showers possible. some rain in the western isles but
