Women are experiencing widespread discrimination when it comes to dress codes at work, say mps. Good afternoon. The top story, President Trump is expected to reveal details later today of how he will fulfil a Major Campaign promise to build a wall along the southern border of america and make the mexicans pay for it. Today he signalled it was important for national security. He is expected to sign several orders aimed at restricting immigration. He has already launched an investigation into voter fraud looking at Illegal Immigrants who were not eligible to vote. Lets have a closer look at the border between the us and mexico. There it is crossing an entire continent and joining the Gulf Of Mexico with the pacific ocean. It passes along four us states and six mexican ones and a wide range of geographical hurdles so any new wall would be a feat of engineering. And heres what it looks like close up. The us border with mexico spans 1,989 miles a Central Plank of President Trumps Election Campaign was to build an impenetrable, physical, tall, powerful, beautiful wall along the whole distance. But hes not starting from scratch walls or fencing like this already spans a third of the frontier between the two countries. And as well as wanting to keep new Illegal Immigrants out he also wants to deport up to 11 million undocumented migrants currently in the United States. So how likely is it that the new president can deliver on his Campaign Promises . We are going to have our nice and strong. We have to build the wall. It was part of the soundtrack of the donald trump Election Campaign, a call to build a wall along the southern border with mexico. It is one of the measures that the president says he wants in place to stem the flow of Illegal Immigrants into the us and as he prepares to signa number of into the us and as he prepares to sign a number of Executive Orders on immigration and Border Security, donald trump is made clear on twitter that the wall will be part of that. Some 650 miles of the border is covered already with fencing and other constructions but the plan is for a walk almost 2000 miles long and donald trump has said repeatedly that mexico will pay. The Mexican Government though is just as determined that will not happen. Translation we recognise the United States has the right to build a wall even though we do not like it. But it is another thing to try to get a neighbouring country to pay for itS Construction. We have said many times this is unacceptable. It is the clear position of the Mexican Government and the mexican people. Donald trump wasted little time signing Executive Orders to set the direction of his presidency. At the start of the weekjobs and trade and among further steps on immigration is expected there will be measures to restrict entry to the us from a number of predominantly muslim countries, the middle east and africa. President trump has also called for a Major Investigation into unsubstantiated claims of fraudulent voting in the us elections. Senior republicans had urged him to drop his claim that voter fraud helped urged him to drop his claim that voterfraud helped Hillary Clinton win the popular vote. Lets speak now to alejandro poire, whos a former Interior Minister for the Mexican Government, and was once head of the countrys intelligence agency, as well as working on anti Drug Trafficking and organized crime strategies. Good to see you. If i could just ask, can you understand why President Trump was my desire to build a wall has resonated with so Many Americans . To begin with it is a largely symbolic gesture i think. It is something tangible that gives individuals especially who are wary about the prospects of globalisation and authorisation and just sheer change in the economy, some sense of security. I think it is a false sense of security, i think it is going to be damaging to the economy both of mexico and the United States as part of the whole changing relationship. I think it is largely a populist, symbolic gesture that is likely to be tangible. One of the few things he might be able to get done. It is fair to say that the majority of illegal immigration into the us from mexico are people who go in legally with visas and so on and overstate the length of their visa. But there is still cross border trafficking of drugs, a Security Issue as far as that southern border issue as far as that southern border is concerned. And there are genuine concerns from americans that that border needs to be tightened up. And i think the way in which you can tighten up security is to work in collaboration and not through walls that are going to make it even harderfor that are going to make it even harder for collaboration to come about. It is notjust drugs that are falling flowing because of us demand, but also guns. Coming from the United States smuggled illegally originally through the United States. The way to handle this is not through separation and insult but through deeper collaboration and shared responsibility. Ithink eve ryo ne shared responsibility. Ithink everyone agrees the best way for mexican workers who are in huge demand in the us in a number of areas of development and growth, is to be done through legal, safe and fair means, both to the workers and also to labourers in the us. I think the symbol of the wall is just a symbol of a century past and policies that have failed. So if the wall goes up your saying that it would cause diplomatic issues and sour the atmosphere between the two countries. But theres nothing tangible that the mexicans would do in retaliation for instance, like withdrawing cross Border Security arrangements . I think there are a number of things the Mexican Government could do and i think both the minister of Foreign Affairs and the minister of Foreign Affairs and the minister of the economy are visiting in washington right now speaking about how if the deal that is offered to renegotiate nafta, mexico would be happy to walk away from the agreement. I think that is the beginning of a Firm Position that i would expect will extend to other areas of collaboration. Just think about the amount of information and the strength of the relationship mexico and the United States have developed together let alone to keep undocumented migrants from getting work that is both safe and productive in the us. From keeping actual threats to the Us National Security apparatus through collaboration and the sharing of information. If we were to put those ties injeopardy i think information. If we were to put those ties in jeopardy i think the population and governments on the us side of the border would also have a lot to lose. Thank you. And Gary Odonoghue is in washington. Given that this wall, if it is built, would be a federal structure, built by the United States government, therefore it would have to be paid for by american tax dollars. The idea that it would ever be paid for by the mexicans was always rubbish . Initially caused during the Campaign Donald trump said mexico would for it and donald trump said mexico would for Itand Up Donald Trump said mexico would for it and up front. He changed his position and said congress would pay for it and he would get the money back. When pressed on this they said the mechanisms for doing that and things like skimming off money from remittances for example. A lot of mexicans send money back from the us Toafamily Mexicans send money back from the us to a family at home by Wire Transfer systems and Different Companies can then intercede and take attacks from that. I guess you could increase the cost of crossing the border illegally. All those are possible but when you look at some of the costs involved, even donald trump says it is 8 billion, others have said Something Like 25 billion. So an enormous amount of money to recoup. He has some power already in the sense that there is an act called the Secure Fence Act from 2006 which allows the president to build a fence along the border rather than a wall. Some of that has already been done, and he could extend that. But really he has nailed his colours to the massed in the past and said it would be concrete, 30 feet tall, and if that does not happen then people will be a bit surprised about his actions in terms of fulfilling his promises. He also announced an investigation into voterfraud. Also announced an investigation into voter fraud. What is the evidence he is putting forward that this has happened because no one else has suggested there has been much voter fraud in the last election. There is no evidence of substances voter fraud at the last election. Bear in mind elections in this Country Are Run County by county around the country by political appointees of all different shades, republicans run elections where they are in charge, as do democrats. The idea that you can get the numbers he will be talking about, he says that a lot of people are dead who have been listed as voters and many Illegal Immigrants. He says up to 5 Million People voted illegally. There is no evidence for that whatsoever. So if there is no evidence what is he on about, is this here and perhaps still trying to come to terms with the fact that he got 3 million votes during the Hillary Clinton . Hes definitely annoyed about that and let us be clear, donald trump won the election fair and square. Under the election fair and square. Under the rules of the constitution. He got 33 states, more electoral votes, 306, he was the winner. But he did get fewer votes in the popular vote, it has happened before but not very often. But he does not like it. I think what will concern some of those who campaign On The Issues is not just that there is evidence those who campaign On The Issues is notjust that there is evidence of voter fraud but that somehow it could be used as a way of continuing a sort of nationwide clamp down on voter id laws, it might make it harderfor people to voter id laws, it might make it harder for people to vote because of course democrats argue especially in those states where you need this photo id to vote, that that penalises their supporters more of the poor people, hispanics, African Americans the poor people, hispanics, african america ns who tend the poor people, hispanics, African Americans who tend not to have that kind of formal id to the extent that the white population has. Thank you. And you can see more analysis of these first days of the Trump Presidency tonight on ioo days with Katty Kay In Washington and Christian Fraser in london at 7 oclock on the bbc news channel. The Prime Minister says the government will set out its brexit plans in a formal policy document, having previously suggested that wouldnt happen. Folowing pressure from labour and some of her own mps, theresa may now says a formal white paper will be published for parliament to debate. It will be separate from the Legislation Mps will vote on, triggering the process for leaving the eu. Heres our Political Correspondent, carole walker. Off to the commons. Are you worried about defeat, Prime Minister . Yesterday the Supreme Court ruled against the Prime Minister, forcing her to consult parliament before starting formal brexit negotiations. That wasnt enough for some mps who complained about the lack of a clear vision of the governments plans. Order, questions to the Prime Minister. But today she sought to seize the initiative with an unexpected announcement. I can confirm to the house that our plan will be set out in a white paper published in this house. A white paper, formally setting out the governments approach, was a central demand of the opposition. The Labour Leader struggled to rethink his attack. Could we know when this white paper is going to be available to us, and why its taken so long to get it . Theresa may said the timing was less important than negotiating a good deal. He and others asked for a white paper. Ive been clear there will be a white paper. What im also clear about is that the right honourable gentleman always asks about process. About the means to the end. I and this government are focusing on the outcomes. We are focusing. Jeremy corbyn was concerned that the promise to protect the competitiveness of the economy would mean cutting taxes on big business. Will she offer some clarity and some certainty and withdraw the threat to destroy the social structure of this country by turning us into the Bargain Basement she clearly threatens . Tomorrow the government will publish the bill to get parliaments approval for starting formal brexit negotiations. Ministers are confident they can get it through without significant setbacks. But long and complex battles lie ahead. Carole walker, bbc news, westminster. Our chief Political Correspondent vicki young is in westminster and we can speak to us now. As many as 20 conservative mps were demanding a white paper on the government brexit plans, was that what forced her hand . Listening to the debate yesterday one after another tories were getting up and saying this is what they wanted. So now theresa may kahan said she has been listening to them, they feel that they are being listened to. And at the end of the day how much of a concession is this really, her official spokeswoman afterward said it was all going to be based on a speech theresa may made last week. They also said mps already know the plan, she already laid that out so im not sure how much more detail we will get on all this. I think that there will be rows once we get into there will be rows once we get into the passing the bill over the next few weeks or so, there will be debates about the final vote, the say that parliament has on the deal. When mike that come. I think the government will be pushed hard on that. Mps are not happy about the above the only get to stay and have their say and they vote right at the end once the deal has been done and then they just end once the deal has been done and then theyjust have a choice between taking the deal theresa may has got or the taking the deal theresa may has got orthe uk taking the deal theresa may has got or the uk leaving the eu, and then returning towards what some call a ha rd returning towards what some call a hard brexit, based on wto rules meaning that there are terrorists. Many mps do not see it as any choice at all. Meaning there are tariffs. One Shadow Cabinet Minister today was unhappy at the idea that Jeremy Corbyn will order his mps to vote to trigger article 50. They said they were prepared to resign from the Shadow Cabinet to avoid that. It will not be enough to stop this going through, the government is quite confident that it will all be fine and they can still stick to their timetable. But over the next few months mps are wondering how opinion might harden and mps might become emboldened to try to hold theresa may to certain things as she goes through that negotiation. This is Bbc News At Five the headlines. President trump is to reveal more details on how he intends to fulfil his Campaign Promise to build a wall along the border with mexico. And mps are to get a chance to scrutinise the government brexit strategy. As new figures show a rise in the number of people Sleeping Rough in england.
