can brexit britain and trump's us beat the likes of ireland at their own game and lure back the multinationals and their billions? donald trump has says waterboarding and other interrogation techniques which are widely seen as torture and prohibited by law absolutely work. but he's also stated he will defer to his cia and pentagon chiefs on whether to reinstate them. his comments came amid reports which suggest his administration may be planning to reinstate secret overseas cia black site prisons. earlier, president trump outlined his plans to construct a new wall along the us—mexican border. james cook reports from that border. he is meant to meet enrique pena nieto on tuesday and that meeting has been put in doubt, in the last few minutes mexico's foreign

minister has said it will indeed go ahead. james cook reports from that border. donald trump's signature pledge is now one step closer to reality. with a stroke of his pen, the new president ordered the construction of a great wall on the mexican border. it would begin, he said, within months. a nation without borders is not a nation. beginning today, the united states of america gets back control of its borders. we're going to get the bad ones out. the criminals and the drug deals and gangs and gang members and cartel leaders. the day is over when they can stay in our country and wreak havoc. strengthening and extending the existing barrier on this frontier will be hugely expensive. mr trump has always insisted that mexico will pay, but mexico says it won't and the president now admits american taxpayers will have to cough up first. so who will pay for the wall? ultimately, it will come out of what's happening with mexico. we're going to be starting those negotiations relatively soon and we will be in a form reimbursed by mexico. so they'll pay us back?

yes. absolutely. 100%. so the american taxpayer will pay for the wall at first? all it is, is we'll be reimbursed at a later date. but here in a mexican border city of tijuana, business leaders are worried about the impact on trade and sceptical about the president's plans. the problem is that the majority of americans are not really familiar with the border and, consequently the idea of a wall seems to be appealing. we already have one. we call it the tortilla curtain, but the truth of the matter is that, you know, i think that's a symbol. this fence at the pacific ocean is the very start of the land border between mexico and the united states and president trump has always said he wants to build a much taller, a much better, much bigger wall, stretching all the way from here, nearly 2,000 miles to texas. # this land is your land.

# this land is my land... but even in liberal california there's backing for president trump's hard line on immigration, not least from these supporters who call themselves the trumpettes. i think it's a good thing. you know, i always say my scriptures ezekiel 22:30, "i sought for a man who build a wall." i was reading that the other day and it just stuck out in my spirit because we need protection, and i pray for america and i pray that god will shore up the border of our nation. as well as the wall, president trump is promising to deport immigrants who commit crimes, to cut funding to states like california which refuse to arrest most illegal aliens and to hire 10,000 more enforcement agents. his actions are bold, sweeping and intensely divisive. james cook, bbc news, on the us—mexico border. in the past hour, mexico's foreign minister has said next week's summit meeting in washington between the us

and mexican presidents is to go forward as planned. earlier, mexico's president condemned the decision by donald trump to build a fortified wall along the us—mexico border. he repeated that his country would not pay for it. from mexico city, will grant reports. in many ways mexicans have been expecting an announcement from president trump about the border wall since he came to office. but when it happened it was still met with a combination of resignation and defiance. resignation as people are finding at least initially that mrtrump is are finding at least initially that mr trump is serious about implementing the very proposals toward mexico that he made as a candidate. translation: well, it's unnecessary. he says that he's building it to stop bad people crossing, that

mexico people are bad, that we are carrying drugs with us but that's not the case. you can't label all of us as not the case. you can't label all of us as the same because there are millions of mexicans who are hard walking, honest and have travel documents to come to the united states. but many are also defiant and are adamant that they will not pick up the bill for building a wall they neither want nor called for. translation: he thinks only about himself. he doesn't care about other people. to me he has every right to build it because it's his country. asa build it because it's his country. as a mexican, what can i say? this will be decided by him and the president of mexico. they are the early ones who cancel this out. if they can't then he will do it. he's already said he will. meanwhile, mexico's embattled president, enrique pena nieto, is underfire over his handling of the issue. he's due to visit his counterpart next

week and is under pressure to abandon the trip. however in a video statement released on twitter, he made no mention of either cancelling or postponing his visit to washington. the mexico us relationship has traditionally been one of the most important in the americas, accounting for hundreds of billions of dollars of bilateral trade every year. but it has been a thorny relationship too and it won't have been made any easier by mr trump's decision to implement one of his most controversial policies so early in his presidency. will grant, bbc news, mexico city. and sally is here with all the business news. donald trump having a positive affect on the financial markets. you heard about his controversy and mexico, traders in new york are ignoring that, they are cheering become perfect. —— the trump effect.

of president trump's strategy to boost the us economy and is on the agenda today at the republican party's annual retreat in philadelphia. president trump will be there to give an address as will british prime minister theresa may, a first for a foreign head of state. before winning the election, mr trump promised he'll cut the us corporate tax rate from 35% to around 15% to try and keep more us business onshore. he's also targeting the billions that us multinationals, the likes of starbucks, google, and microsoft make overseas. mr trump says he'll allow them to repatriate those profits at a 10% tax rate. that's what he said anyway before his election. but the us president is likely to face competition. uk prime minister theresa may has pledged she will deliver the lowest corporation rate in the g20 as the uk tries to make itself attractive to big companies once it

leaves the european union. it's currently at 20%. and just next door is ireland, which is in the european union, has had big success luring multinationals. the likes of apple, intel and pfizer are some of the big american companies based there. its controversial arrangements include corporation tax of just 12.5%. lots more on this in 20 minutes' time. and we'll have all the other business stories as well. a giant aircraft on loan from the united states has arrived in chile to help tackle the worst wildfires in the south american country's modern history. a state of emergency has been declared in a huge area south of the capital, santiago. chile's president has ordered extra funds and resources to fight the fires, as people ask for help to save their homes. sarah corker reports. in the tinder dry conditions,

as katie gornall reports. in a sport measured in fractions of a second, this was an astonishing feat of longevity. commentator: the triple triple! he's done it. usain bolt‘s nine fold medals, at three different olympics, was unprecedented. now, through no fault of his own, that history has been tarnished. the reason lies with this man, nesta carter, bolt‘s team—mate in the relay at the 2008 beijing olympics. his start propelled jamaica both to gold and to a world record. but last year, carter's sample from these games was retested and today he was found guilty of doping. under the ioc rules, the whole team is now disqualified. it's an outcome that bolt has feared for some time. i asked him about it back in august in his hometown of kingston. at any point, if i lose one of my medals it'd be devastating and stressful, do you know what i mean? to know that, after all that hard work, this would happen. but i think the sport is in a really bad place now and the only place it can go right now is up. it must be hard as well

because the triple triple is such a special achievement? it's very, very, very special, but we'll see. fingers crossed. sadly, whilst bolt stood clean, his rivals have fallen around him. justin gatlin has been banned twice forfailing drugs tests. tyson gay has tested positive for an anabolic steroid and his fellow jamaican, asafa powell, has served a six—month ban. today, nesta carter was found to have taken the banned stimulant methylhexaneamine. my my personal opinion is that i am surprise. bolt will now have to hand back one of his precious medals, still he'll retire with his legacy intact. katie gornall, bbc news. southampton have reached the final of the efl cup in england. beating liverpool in the semi final by 2 goals to 0 over two legs liverpool trailed by a goal going into wednesday's second leg at anfield. and daniel sturridge had their best
