president trump has signed a declaration of national emergency to build a barrier along the border with mexico. the executive action will allow him to bypass congress and secure funding for his promised border wall. here's a graph from our website, danjohnson is on the us side of the border at the town of san ysidro south of san diego. donald trump the original aim was to com plete donald trump the original aim was to complete a wall across the sport or to stop people and illegal goods flowing across from mexico. his plan was that with a secure border those goods, those people will be funneled to crossing points like this and that it wall would also free up border agents to focus their attention here so the more drugs, war criminals attention here so the more drugs, warcriminals and attention here so the more drugs, war criminals and more illegal immigrants could be intercepted but he has failed in getting the five and a half billion dollars he wanted

from congress. this deal is $4 billion short and that's why he stepped up his action today and announced a state of emergency. that is already disappointed people and politicians on his own side of the democrats already saying his sin a legal declaration about a manufactured crisis. the controversy will not be over anytime soon. this split american opinion gridlocked government like never before. we are going to confront the national security crisis on our southern border and we are going to do it when we are the other, we have to do it. they say walls don't work, walls work 100%. i'm going to be signing a national emergency. we are

talking about an invasion of our country. with drugs, human traffickers, with all types of criminals and gangs. the final footsteps of that human trafficking trail. after a journey with the fence runs out this mother and her daughterfall into fence runs out this mother and her daughter fall into the arms of us border patrol. my little girl is hungry, she says, and i don't have any money. there are over 1000 more who cross illegally every day. there's already a fence at one kind 01’ there's already a fence at one kind or another along the third of the mile border. it's already being upgraded and making a difference. this period takes a significantly

more time to penetrate, to cut through. it takes ten, 20, up to 30 minutes to the blade you are using. this can be compromised in about a minute and 20 seconds. he shares the ambition to extend this fence. we have to have a barrier and we will never win that distance game. the smugglers are using those people and trying to claim asylum as a distraction to overload my resources so distraction to overload my resources so they can fund drugs and other areas. but the numbers are way down. i would say it's knuckling like it was. it would be easy to question the rhetoric. his talk for crisis and the threat they pose how simple he makes a wall sound as a solution. it's clear there is a complex game of cat and mouse being played here and the border patrol agents say it's unsustainable. manpower,

horsepower, all of it is stretched and donald trump steaks so much on defending this border and seeing this fence go further. now it looks like this fight will go to court. president trump talked about an invasion of drugs, people and gangs and is that how people there would categorise it? no, the majority of people think that that sort of language is exaggerated. there's about a thousand illegal crossings every day in the border patrol agent said they cannot cope with that they are having to chase people across the desert and there catching people who want to claim asylum but have to process them and they don't have the facilities to do it properly. the system is so backlogged that even when people have claimed asylum it ta kes two when people have claimed asylum it takes two or three years for their future to be properly determined. everyone would agree that that situation is untenable and that something does need to change but the way the president characterises this a lot of people sayjust does

not reflect the reality here on the border so that's why there is of such strong opposition to his plan. some people think purely and simply building a wall would be a hugely wasteful expensive use of money that would not really be worthwhile. they think the money should be invested more in technology and in extra resources here and across the points where the majority of drugs are smuggled through. that's where people think the hinge points are. they believe without completing the border properly and freeing of the agents to focus here you cannot really have an effective border solution. looks like this is going to go on for a long time yet because already the legal challenges are coming in and the president himself that he expected that this one would probably go all the way to the supreme court. thank you. the head of britain's intelligence agency, m16, has warned that so—called islamic state still poses a threat, and is regrouping for more attacks, despite losing much of its territory in the middle east. alex younger says he's concerned

aboutjihadists returning to europe, who've acquired "skills and connections" making them potentially very dangerous. he was speaking after the london teenager shamima begum, said she wanted to return to the uk, after running away to become a jihadi bride four years ago. our home affairs correspondent daniel sandford has the latest. inside this camp in northern syria, and the women and children who fled from the fighting in one of the last strongholds of the islamic state group. filmed earlier this month, this is where the former bethnal green schoolgirl shamima begum is staying, along with other british women who've been with is for four years 01’ more. today, alex younger, the head of the secret intelligence service, m16, said... some 850 people left the uk tojoin is, and around half

have already returned. but this morning the home secretary, sajid javid, said... we have to be clear that people who leave this country to support that regime are people who, if they do return, have to answer for their actions. so what does that mean for shamima begum, who left the uk aged 15, has lost two children and is pregnant with a third? could she have her citizenship taken away? if she doesn't have another nationality, as i believe to be the case, then it is morally unacceptable to refuse her entry, as well as legally unacceptable, because otherwise she would be stateless, and no person in the world can be stateless under the law. so if she can make it to the uk, she might get in, but she still

seems hardened and radicalised. but rashad ali, who is an expert in de—radicalisation, says is supporters can be turned round. we know, in the uk, we have worked over the last ten years with fairly hard—line, violent extremists who have renounced their ideology, have remorse for their actions, and have taken part, actually, in helping others move away from extremist tendencies and violent ideologies. the kurdish red crescent says there were over 1,000 new arrivals at al—hawl just this morning. decisions will have to be made soon about what to do with the british is supporters among them. daniel sandford, bbc news. let's take a look at some of

the latest headlines. the us president donald trump has declared a national emergency in an attempt to bypass congress and secure funding for his mexican border wall. let's stay with our top story, donald trump's declaration of a national emergency in the us, to bypass congress and build a wall along the mexican border. we can speak now to william galston, senior fellow at the brookings institution — a us think thank. thank you forjoining us here on bbc world news. president trump, eve ryo ne world news. president trump, everyone else expects this to end up in the courts, what is likely to be the legal argument against this move? there may be a number of legal

arguments against this move if the court chooses to get involved in a factual determination may well find that there were not factual grounds to declare a national emergency or they may find that the statute does not allow the president to do with the president is seeking to do or they may find that although the statute is consistent with the president's action it's not consistent with the constitution. there of the possibilities but those of the main ones. let's go back to the first one you mentioned which is the first one you mentioned which is the basis of facts and that comes down to what constitutes an emergency. let's have a listen if we made to something the president trump said earlier. i want to do it faster. i could do the wall over a longer period of time, i did not need to do this but i would rather do it much faster. i did not have to do it much faster. i did not have to do it much faster. i did not have to do it for the election, i've already done a lot of wall for the election.

2020 and the only reason we are up you're talking about this is because of the election. i don't need to do this, but i want to do it faster, is that likely to get him into some trouble in the courts? well, there is an issue as to which kinds of presidential utterances have a legal weight for court purposes. this is an issue that arose during the effort early in the president's term to restrict immigration from majority muslim countries. by and large the courts have taken a pretty dim view of relying on those state m e nts dim view of relying on those statements as the basis of legal arguments for or against. i cannot rule out the possibility could do some damage to his cause but i don't think it's likely. turning to the constitutional arguments than many are arguing that this is executive overreach. well, that is shorthand

for a much more complicated argument. 0ver for a much more complicated argument. over the past four days the congress of the united states has granted the president more than 120 separate kinds of emergency powers to be invoked in specific circumstances and in the same way that the executive cannot give away power to the executive power to the legislature under our constitutional system it's possible to argue that the legislature cannot give legislative power to the president as it has repeatedly. this is the first time to my knowledge that this specific issue has been litigated in a related issue was litigated during the korean war when harry truman seized the steel mills because they we re seized the steel mills because they were not cooperating with his effo rts were not cooperating with his efforts to bring down prices but that reflected a general assertion

of executive power and not one based on specific legislation. thank you very much forjoining us. holly hamilton has all the sport. watch for kicking things off this evening. we are into the second half where watford has taken the lead scoring for the visitors just before the break and we will need to hold on if they want to progress to the quarterfinals of this competition for the first time since 2016. tomorrow's a real case of david and goliath. the premier league champions manchester city travelling to south wales and michael flynn summed it up by the weight speaking to the bbc admitting victory would be the biggest upsetin upset in the competition history.
