if first narratives. i also think if i may add, this is actually good news for all of america's allies. what we've seen our two positive, responsible constructive meetings, back to back with prime minister abe and prime minister trudeau, back to back with prime minister abe and prime ministertrudeau, having seen very different kinds of interactions between the president and the prime minister of australia and the prime minister of australia and the prime minister of australia and the president of mexico. to good meetings may be a pattern, i think we can hope that. —— good meetings. it shows there is a very different attitude in government are what we heard on the campaign trail. thank you for being with us. let's talk about that southern border because among a number of executive orders the president has signed that our two that relate to the us—mexico border. one gives the green light to begin work on the wall, the other increases the size of the border patrol force, as well as the number

of immigration enforcement officers who carry out the deportations. the third of the frontier already has some sort of barrier and the nearly a decade people who live in the towns that straddle the mexican—american border have had to adapt to that. we report from the border town of el paso which lies on the american side, and ciudad juarez on the mexican side. 2:30am. this man is about to cross into the united states. for many on the border it's a way of life. we are protecting his identity because the american company he works for doesn't allow him to speak. this is the kind of journey doesn't allow him to speak. this is the kind ofjourney many people in ciudad juarez make to go and work in el paso. he's mexican, he is building the wall, the wall that is already there. for my job it'sjust

to make of all this time. his family and friends do not see it as a problem either. they joke with me and say leave it open for them to cfoss. this is where luis is working on a two kilometre stretch of the fence. he believes the us needs people like him. standing so close to it, it's obviously a very imposing structure. they used to be a small offence here but it is now being replaced by this five metre high metal post. the closer you get to the fence the more you wonder how the wall president trump wants to build will serve its purposes and how it will affect the lives and businesses of people in border towns.

this man is from ciudad juarez and owns a small restaurant in el paso. since trump was arrested the mexican currency, the peso, has tumbled, and his business has suffered. —— since trump was elected. there's been a fence here for almost a decade, and while ciudad juarez became one of the most violent places in the world el paso is amongst the safest cities in the us. they willjust cross right here. the barrier runs through this woman's backyard. we have less people crossing. we have less cargo, as we say, crossing over. now we feel safer.

despite her mexican heritage she supports president trump's plans. i believe that he is trying to protect the us. and i believe in that. all along the border there are reminders like this that for some the impulse to cross this fence or a future wall may be too strong to stop. this is the photo we were showing you last week as trump was signing

one of the executive orders. the top men in the closed circle. steve bannon standing just on right shoulder. obviously a very prominent position within the administration. very young but very influential. he is said to have the error of the president. he relies on him for policy —— the ear of the president. he relies on him for immigration particularly. he did and get great reviews from his tv performances but it seems donald trump really likes him. he tweeted this, congratulations stephen miller on representing me this weekend on various sunday morning shows. great job. we know donald trump has confidence in stephen miller but does he still have trust in michael flynn? the general is under mounting pressure, speculation that in the week before he took office he was talking privately to the russian ambassador about relaxing sanctions on russia. throughout the weekend

both stephen miller and the president ducked questions about his future. what do you think about reports that general glenn had conversations with the russians?|j haven't conversations with the russians?” haven't seen it. what report is that? there is a report to talk to the ambassador of russia before you we re the ambassador of russia before you were inaugurated. i haven't seen that. i'll look at that. how can he continue to serve as national security adviser after misleading the president? i don't accept that question as accurate. i don't have any information to add anything to this conversation. i understand it's a sensitive and important matter. i'm sure you'll have an opportunity to interview someone from the vice president's office... i'm sure you're well aware of the 1799 logan act, a well—known statute. that's not the problem though, forget about

the logan act. the problem is the vice president went out on national tv and said that flynn never discussed those sanctions with the russian ambassador. very bad position for the vice president to be in. not great for general flynn to be in. i'll be back for facebook live. so do get in touch, this is 100 days from bbc news, from katty kay in washington and me, christian fraser in london, goodbye. hello. this is bbc news. the headlines. a scientist from newcastle university says banned chemicals from the 19705 have been found in the deepest reaches of the pacific. it's believed to be the first evidence of pollutants affecting one of the most remote habitats on earth. our correspondent fiona trott has more details. take a look at this. this crustacean that used to live ten kilometres down in the pacific ocean. what scientists at newcastle university have found is that there are

chemicals inside that were banned in the 19705. doctor alan jamieson joins us, what does that mean for u5? joins us, what does that mean for us? it means some of the most remote marine habitats on earth are contaminated with chemicals entirely man—made, which i think is quite a sad story really. what kind of chemicals are you talking about? we found chemicals that were introduced in the 19305 and 405 for various industrial applications. they were accidentally released but eventually when it was realised they would never degrade in nature, they were banned in the 19705. unfortunately they don't ever disappear, they keep passing from animal to animal, going through the food web. in the deep sea, the deep sea derives its food and energy from the surface layers. it all ultimately sinks. once it sinks to the deep sea there is nowhere left for it to go so it

accumulates. what else has been found on the ocean bed. we've seen things like beer cans at 7000 metres, a raincoat at 10,000 metres. the japanese have seen a lot of litter around japan. we are starting to see more and more plastic. if you think about the great north pacific garbage patch, people are very aware of that but they aren't perhaps so aware that it all has to sink. it all fragment and find its way down into ecosystems that we don't understand. what other research are you going to be carrying out? we will continue looking for places where no one else cares. maybe the next level is to look for microfibres and micro beads. thinks you find in cosmetics and cleaning products? yes. when we think of the pcb ‘s products? yes. when we think of the pcb ‘5 story, these things were created with the best intention and released by mistake. when it was

realised it was a mistake they were banned. 50 years later we have just done exactly the same thing. with the producer of these products with micro beads and send them down the plug coal, it turns out they don't magically disappear. they underpinned the sea and will perhaps end up in some of these extreme environments. thank you. researchers in the north—east of england finding there are ten times more pollutants in crustaceans like these and earthworms. that's why their next level of research will be the kind of impact this may have on the wider ecosystem. we have a full hour of news but first the weather. the weather is undergoing something of a transformation at the moment. if you cast your minds back to the weekend, it was so cold and bleak. three degrees was typical on sunday afternoon. fast forward to today and while some of us continue to shiver,

for others it was gloriously sunny. and it felt like spring. across the cornish coast, this is the shot from our weather watchers. many parts of the uk enjoyed some welcome sunshine at last. not for all. across the far north—east of england and eastern scotla nd north—east of england and eastern scotland it has stayed persistently cloudy and cold. on the aberdeenshire coast, four celsius was the best we could offer. things will warm up with time. not yet. a change in the weather across the far south—west of england, with rain turning up. no great dramas weather—wise. under clear skies it will be cold with temperatures close to freezing in one or two places. a different start of the day across the south—west of england. no great amounts but you need something waterproof if you are heading out. some cloud pushing up, and lots of sunshine from the south—east up to the north west of the uk. chilly but

temperatures will bounce back. once more across the far north—east of england and eastern scotland, will probably still be draped in cloud. that will knock the temperatures on the head once more. many of us will have a fine day. this rain pushing up have a fine day. this rain pushing up into wales and northern ireland. eventually it will brighten up across south—western parts of england. another relatively mild day with double figures in some places, relatively chilly once more. particularly where you are exposed to that winter. the weather is coming in from the south—west, that isa coming in from the south—west, that is a milder source of air but it's carrying some weather systems. this one will bring some rain again to south—western parts of the uk initially on wednesday. patchy rain but some sharp bursts will spread into other parts of the uk in time. there will be some rain around. probably the best of the brightness across the north—east. temperatures

heading in the right direction. double figures further south. this is bbc news. i'm clive myrie, the headlines at eight. move away from me unless you want me to use it on you. a bbc undercover investigation has exposed widespread drug abuse and security failings at one of britain's biggestjails. there are calls to reduce the prison population, but the justice secretary says there are no easy solutions. this will not be fixed in weeks or months. but if we are resloute we will see our society safer and we will see our prison population reduce. president from the canadian prime minister have stressed their resolution to working together at a summit meeting. four people have been killed in an avalanche in the french alps, while skiing off piste. tesco has promised urgent action, after a bbc investigation found many advertised promotions,had actually expired.
