brief you on all you need to know on global news, business and sport. and you can be part of the conversation. we've been tracking events in davos all week. is it a critical way for world leaders to get their messages out? or hot airfor a cold climate? there's a question. tell us what you think. just use the hashtag bbc—the—briefing. donald trump will deliver his keynote speech at the world economic forum in davos later. the us president has already made his presence known at the gathering of world leaders, offering better trade deals and inviting big business to invest in america. mr trump has also threatened to stop aid for the palestinians unless they take part in peace talks with israel. our north america correspondent peter bowes reports. unfamiliar territory the donald trump. arriving in davos amidst a world wind of expectation. —— whirl—wind. the first us president to show up since bill clinton 18 yea rs to show up since bill clinton 18 years ago. but mr trump, a salesman in chief, is already stealing the show. it's very exciting to be here. we are very happy to be here. the united states is doing very well. the america first president came with a message of peace and prosperity. first a meeting with the british prime minister theresa may, after cancelling a trip to london to open the new us embassy, the president was keen to say they are still friends. he also promised a tremendous increase in trade after brexit. the prime minister and myself had had a really great relationship, although some people don't necessarily believe that, but ican don't necessarily believe that, but i can tell you i have tremendous respect for the prime minister and what she's doing. next, a meeting with the israeli prime minister benjamin netanyahu, who thanks donald trump for recognising jerusalem as the country's capital. the palestinians have said they no longer view the us as a neutral roker in peace, but the president had an ultimatum for them. no more money unless they come to the table. —— broker in peace. money unless they come to the table. -- broker in peace. we give them hundreds of millions of dollars in aid and support, tremendous numbers, numbers that nobody understands. that money is on the table and it's not going to them unless they sit down and negotiate peace. but davos is about trade and a meeting with european business leaders gave mr trump another opportunity to sell america. a theme which are protectionist president will pursue further in his keynote address. he is audience of free traders may be sceptical —— is. but with the us economy booming, donald trump is clearly savouring the moment. the bbc‘s sally bundock is in davos and shejoins me now. sally, peter talking about the wave of expectation, but intrigued too as to how donald trump will make all of this feat. absolutely. it's a family —— funny atmosphere. i was amongst the crowd you saw in that report, where there were just throngs of people trying to get pictures of him and trying to see him and i was among that crowd it was a really awkward feeling as he sort of walked up awkward feeling as he sort of walked up the stairs and waved to everybody and he said, shouted four times, peace and prosperity. and the people around me at that moment were just kind of laughing and there was a bit of awkwardness about it. there was a bit of disbelief about what he was sort of saying as he climbed the stairs to go into one of his bilateral meetings. so there is a funny feeling here. many of course feel that it's great to have a sitting us president here, but of course his message is at odds with what the world economic forum is supposed to be all about, which is globalisation, ways to work together, sharing, connectivity, all of that kind of thing, but then the us delegation here, and they've got the biggest delegation that ever come to the forum in its history, they are at pains to say that they are in message, we are saying america first, but that does not mean that's not good for the rest of the world. in fact, the global economy is doing rather well because of our america first policy. therefore the global economy will boom as the world's biggest economy booms. to a certain extent has he already won this argument? we saw him at the roundtable with european business leaders. they were big east of european industry and business and many of them were saying we are building a new product and in the us. —— big beast. that everything donald trump insisted should be the way ahead. for sure. i mean, people wa nt to way ahead. for sure. i mean, people want to do deals and they want to get a piece of the action, because of course in the us american companies are enjoying a lot of cash back. their corporate tax rates have dropped significantly, so they are ina dropped significantly, so they are in a position to expand, to invest, to do deals and to basically explore other avenues and so business leaders who are here are looking to make the most of this opportunity, this sweet spot, as it were, in the global economy. what was interesting as well if there are some delegates here who have said that in a boycott —— that they will boycott president trump's speech, or at least the press has reported they may do so. one chief executive has actually penned an open letter, saying that african delegates should boycott the speech following the leaks from the white house as to what the president supposedly said in a white house meeting about african countries and caribbean countries. it was said that he said some quite sort of overt racist language with regards to african nations, so there is a bit of boycott as it were that is reported to be happening this afternoon, as far as some of the african delegates who are here who feel that they shouldn't be listening to his speech. so we will be interesting to see how things play out today. i think mr trump is one of those people who will never be able to say he can please all of the people all the time. thank you very much for that, sally. we will have more from davos in the course of the briefing. the issue of trade policy under president trump could be about to get very real for thousands of aircraft workers later today. us regulators will decide whether to back huge tariffs, or taxes, of pushing 300% on imported planes made by canadian firm bombardier. the us says it would make up for unfair subsidies the firm gets from the canadian government, following a complaint by rival boeing. thousands ofjobs could be at stake. and notjust in canada, many in northern ireland where bombardier‘s wing factory is the biggest private employer. kulveer ranger is the vice president of strategy and communications at atos. hejoins me now. this is obviously a huge issue, not just in trade policy for the us, but politically we know trump was meeting theresa may in the course of discussions yesterday. it's a big issue for her. this has almost become totemic in the way this particular squabble between boeing and bombardier is playing out. it comes to the question of state aid. where do big global companies get funding? the argument about whether bombardier has been receiving unfair funding from us... sorry, from the uk and canadian government. but really it's a test of that america first policy. this is a major test, this is what donald trump has been talking about. he is playing to the idea of bringing jobs back and making it more fairfor american business. the argument here where re—hab the us trade commission looking at this deal, the trump administration has lead its card about raising taxes. that will make it untenable for bombardier to build this 292% tax on this. so the argument is around that, but the local politics, if we can say it from the national level, it is interesting. yes, donald trump wants to be seen as doing what he has promised, which is bring big business back to the us, but the dynamic for the uk, and business back to the us, but the dynamic forthe uk, and it business back to the us, but the dynamic for the uk, and it brings in the conversation of brexit, because prime minister may has had to do with deal with the dup party in northern ireland, to buttress her administration, the political dynamic for the uk is very fragile and that's why we've had this conversation in davos between prime minister and president, where this was probably really at the top of the agenda. about how he could help her smooth things out locally for her. it's like political shrapnel in a way, as a result of what's going to happen. we will leave it there for now. and kulveer ranger will be back in about half an hour to review the main stories being covered by the global media. let's brief you on some of the other stories making the news. more than a0 people have been killed in a fire that swept through a hospital in south korea. the fire is said to have started in the emergency room and it's believed to be south korea's most deadly fire in more than a decade. the canadian sport minister, kent hehr, has resigned while the government investigates allegations that he made inappropriate comments to women. earlier, patrick brown stepped down as the leader of the opposition progressive conservative party in the province of ontario over allegations he made unwanted sexual advances to two women. he denies the claims. white house officials have outlined proposals to give $1.8 —— 1.8 million young, undocumented immigrants a path towards us citizenship. in return, the trump administration is insisting congress approve a $25 billion fund to finance a border wall with mexico. the trade—off also envisages tougher immigration controls. the european space rocket experienced an anomaly during its latest launch. telemetry was lost about nine minutes into the flight. controllers tried to determine the status of the rocket and the satellites it was carrying. eventually radio signals from the spacecraft were picked up. the oscar—winning actor casey affleck has pulled out of this year's oscars ceremony, where he was expected to present the award for best actress. he won his oscar in 2017, despite having been accused of sexual harassment by two female crew members on an earlier film, claims he denies. reged ahmad reports. less tha n less than a year ago casey affleck was riding high on his best oscar win for manchester by the sea, but even then he was dogged by harassment allegations. those allegations became centrestage in 2017 when brie larson, who presented the statue to him, looked visibly unimpressed and refrained from clapping. and for a performance by an actress in a leading role, sally hawkins, in the shape of water. by tradition casey affleck was supposed to present the best actress award, but now his publicist says he has pulled out. a spokeswoman confirmed the move, saying: i think his publicist and his team knew that he would be difficult for him to walk the red carpet and deal with the press and reporters without being inundated with questions. the brother of hollywood star ben affleck, casey was sued by two co—stars. sure harassment. he denied the claims and it has been settled out of court. the latest development has brought renewed focus to the industry, since multiple actresses went public with accusations against us movie mogul harvey weinstein. those allegations gave rise to the me too hashtag, leading women and men to share their stories of harassment. more recently celebrities wore black at the golden globes to honour the victims of sexual harassment, while more than 300 actresses, writers and directors launched the times up project, to fight sexual harassment industry and other workplaces. although the focus this time is on casey affleck, it certainly seems there is more to play out in hollywood as the underbelly of the industry continues to be exposed. stay with us on the briefing. also on the programme: can south korea's first grand slam semi—finalist upset the odds again? chung hyeon takes on roger federer at the australian open. that and more in the sport briefing. the shuttle challenger exploded soon after lift—off. there were seven astronauts on board, one of them a woman school teacher. all of them are believed to have been killed. by the evening, tahrir square, the heart of official cairo, was in the hands of the demonstrators. they were using the word "revolution". the earthquake singled out buildings and brought them down in seconds. tonight, the search for any survivors has an increasing desperation about it as the hours pass. the new government is firmly in control of the entire republic of uganda. moscow got its first taste of western fast food as mcdonald's opened their biggest restaurant in pushkin square. but the hundreds of muscovites who queued up today will not find it cheap, with a big mac costing half a day's wages for the average russian. you're watching the briefing. our headlines... president trump's set to give his keynote speech — promoting us trade — at the world economic forum in davos. casey affleck has pulled out of presenting an award at next month's oscars. he's been under pressure over claims of sexual harassment, which he denies. polling booths are due to open shortly in the czech republic for the second round of the country's presidential election. the incumbent, milos zeman, is seeking a second five—year term, his challenger, jiri drahos, says that he no longer has anything to offer his country. the bbc‘s rob cameron joins us now from prague. this would perhaps be billed as a david versus goliath sort of a challenge, but it is very close, i understand? it is extremely close, it should be remembered that the czech republic is a parliamentary democracy and the post of czech president is in theory a ceremonial one but he wields huge influence and even some power in this country. he sets the tone here, and indeed the whole of the public discourse. when we have a president like milos zeman who makes very, very public overtures to authoritarian regimes like russia and china, who is critical of such things as the eu sanctions against russia over crimea, it really does set the tone for debate in this country, and his critics say it is unsettling the czech republic's traditional allies in the eu and nato. this is the key point, isn't it? we are at a political juncture as to point, isn't it? we are at a politicaljuncture as to which way the czech republic, but perhaps you can look at poland, hungary even, which way they really want to go in terms of their relationship with the eu? exactly, that is what this election is really all about and milos zeman's challenger, jiri drahos, he is an academic, a professor, a man with almost no political influence at all but he says that president milos zeman in his first five years really has taken this his first five years really has ta ken this country his first five years really has taken this country in a direction it should not be going, it is time to reaffirm the czech republic's place in europe, it is time to reassure the czech republic's allies in the eu. he wants to reassure the eu and provide a new, more sober, perhaps more genteel face to the outside world than the sometimes rather vulgar and indeed now ageing, world than the sometimes rather vulgarand indeed now ageing, mr milos zeman. he now says it is time for age, milos zeman. he now says it is time forage, mr milos zeman. he now says it is time for age, mr milos zeman says you have no political experience, leave it to have no political experience, leave ittoa have no political experience, leave it to a political matador, one of the last tight ends in czech politics. a fairly black-and-white political argument, but we do not know which way it is going to be yet. thank you very much indeed. emergency services are helping evacuate victims of flooding in areas around paris, as the seine's rising levels continue to cause havoc and inundate parts of the french capital. the river isn't expected to peak until the weekend, as richard forrest reports. this is an area east of paris. suburbia submerged. fields, streets and parts of houses underwater. here, emergency services and even soldiers have been enlisted to rescue residents. but it's just one area that's been hit. the misery is being caused by the river seine, which runs through paris. record rainfall has pushed it and other rivers over their banks across north—eastern france. parts of paris too have been inundated. tourists and residents have been asked to stay clear of river banks, with train stations that service ket tourist sites closed, even parts of the louvre museum. it is crazy. i have been to paris before. and this is crazy. yeah, it's so much water. well, it gives paris another perspective. it is still beautiful, but we just travel differently. the river seine's levels are still steadily rising, yet to peak and offer some relief. translation: the situation is under control but will still continue throughout this weekend. we are not certain the peak of the flood will be this saturday, but weather forecasters predict this will be the case. until then, the city will have to cope. the mayor says this flooding comes off the back of summer heatwaves and earlier floods, and that paris willjust have to just adapt to climate change, expecting more of the same. richard forrest, bbc news. that is quite a clear message. now it's time to get all the latest from the bbc sport centre. hello there. coming up in your friday sport briefing... south korea's hyeon chung looks to upset the great roger federer at the australian open. alexis sanchez is set to make his manchester united debut in the fa cup later. and play gets under way shortly on day three of the third test between south africa and india. now, could we be on for another shock at the australian open? there's not long to go before the start of the second men's semi—final. south korea's hyeon chung has already beaten novak djokovic in melbourne, but now he's got to get past 19—time grand slam champion, roger federer, who's still yet to drop a set. last time out, chung blew past american tennys sandgren in straight sets to book his place in the last four. no korean player has been further in a grand slam, but the challenge now facing the world number 58 is the biggest of all. he's the highest paid player in premier league history and alexis sanchez could be making his manchester united debut later on friday, in the fourth round of the fa cup at yeovil town. the lowest ranked team left in the competition take on the 12—time winners, and the united bossjose mourinhio is looking forward to seeing his new signing in action. i got igota i got a fantastic player, arsene wenger got a fantastic player. alexis sanchez changed from a fantastic player to a giant club, and henrikh mkhitaryan changed also for a fantastic club. so i think it was a great deal for everybody. tiger woods made his competitive return to golf on thursday at the farmers insurance open in california. the 42—year—old, who last featured on the pga tour at this event last year, carded a level—par round to sit seven shots off the pace at torrey pines. the second round of the dubai desert classic on the european tour is under way. with sergio garcia and rory mcllroy teeing off at 8:20 gmt. defending champion garcia had a solid first round 67, and the spaniard is looking to continue last year's great form, where he won the masters. by contrast, mcilroy had a frustrating 2017. he was sidelined by a rib injury in october, but has impressed on his return in abu dhabi last week with a third place finish. he's also in contention after a first round 65. now, in case you missed it, holders barcelona are through to the semi—finals of the copa del rey. they overturned a first leg deficit against their city rivals, espanyol, to seal their place in the last four. luis suarez scored for barca after only nine minutes to wipe out espanyol‘s 1—0 lead from the opening leg. midway through the first half, lionel messi made it 2—0, which gave them a 2—1 aggregate win and they join leganes, sevilla and valencia in friday's draw. now in the cricket, day three of the third and final test between south africa and india in johannesburg resumes shortly. it's been low scoring but exciting as india ended the second day on 49/1 in their second innings — a lead of 42, after their bowlers dominated in the same manner as south africa's had on the first day. now losing on the some of the biggest stages in sport can be hard to take. but on social media, kyle edmund has been very gracious in defeat. the briton lost in the semi—finals of the australian open to marin cilic. and posted his thanks to the tournament and his fans for an amazing couple of weeks. the 23—year—old's run to the semis was one of the stories of the tournament, and he says he can't wait to be back next year. in the women's draw, world number two caroline wozniacki was on the right side of her semi—final. she beat elise mertens in straight sets to set up a final with world number one, simona halep. neither player has won a grand slam. and she just posted this picture. and that finals feeling! you can get all the latest sports news at our website — that's bbc.com/sport. but from me, that is your friday sport briefing. all week, we have had a real does from davos. our question on social media for the day is simply this, is it great to hear from the mall or is it great to hear from the mall or is it simply hot air in this climate?
