i'm mariko oi in singapore — the headlines... putting the president on trial — the impeachment of donald trump gets under way in the us senate but so far the democrats aren't being allowed to call any evidence or witnesses. a trial with no evidence is not a trial at all, it is a cover—up. the president himself is thousands of miles away in switzerland at the world economic forum. it's just a hoax, it'sjust a hoax, it it's just a hoax, it is the witchhunt that has been going on for yea rs witchhunt that has been going on for years and frankly it is disgraceful.

i'm kasia madera in london. also in the programme... health chiefs warn that a deadly pneumonia virus is spreading beyond china with a case confirmed in the us. and could a spot of meditation in the office help boost staff morale? we visit the singapore start—up where mindfulness is part of the working day. live from our studios in singapore and london. this is bbc world news. it's newsday. good morning. it's 8am in singapore, midnight in london and 7pm in washington, where the impeachment trial of president trump has officially started in the us senate. not a lot of progress yet, though. republicans and democrats can't even decide on how it should proceed. here's our north america

editorjon sopel. hear ye, all persons are commanded to keep silent on pain of imprisonment. 1868, 1999 and now 2020, for only the third time in american history, the sergeant at arms tells senators on pain of imprisonment that they must maintain silence in the trial of a sitting president, the asth, donald] trump. presiding over it the chief justice, john roberts. but all for this being a judicial process, it is really raw politics. the first person to be called was the senior white house counsel acting as the defence. we believe that once you hear those initial presentations, the only conclusion will be that the president has done absolutely nothing wrong.

and that these articles of impeachment do not begin to approach the standard required. the central argument is whether witnesses should be allowed. the republicans want the trial to be done and dusted in a little over a week, with no one called to give evidence. the chief prosecutors is adam schiff. he says that would be a travesty. if the defendant is not allowed to introduce evidence of his innocence, it is not a fair trial. so too for the prosecution. if the house cannot call witnesses or introduce documents in evidence, it is not a fair trial. it is it not really a trial at all. trump may be with the global elite, but he is watching what happening in washington. it is a hoax, it goes nowhere because nothing happened. the only thing we have done is a greatjob.

we have the strongest country in the world by far and it's going on a great direction. we have the greatest economy ever in our history. the trial will last for at least a week. then there will be questioning. all of this will be conducted with the strictest rules of behaviour. but on the the cable news networks, it is playing out 24/7 — and here it's mixed martial arts with seemingly no rules. this fight for public opinion is just as important as donald trump eyes re—election later on this year. that argument is continuing in the senate, this is a live shot now where they are basically arguing over how to proceed with the impeachment trial. two amendment so far: for more documents from the white house and state department on the trump administration's contact

with ukraine have been rejected straight along party lines. fascinating how that has gone straight down party lines. chris buckler is in washington for us. so far the two amendments voted for as one would expect when it comes to the way the senate is represented. yes, 53 republicans, 47 democrats essentially is the way it has been split down the line between the two caucuses who vote. as it stands it means white house information and evidence the democrats had been seeking they will not be allowed to introduce, and also state department information that they had wanted, they will not get those either. what they will not get those either. what they are now debating is whether they are now debating is whether they can get documents from the offices of management and budget. there are important because you might remember one of the key allegations against president trump is that he threatened to withhold military aid ukraine unless the

country launched investigations into his political rivals for purely domestic political reasons. as a result, you can expect the democrats will be making that argument very strongly, but they need to see anything that went before the desks of the omb who are responsible for providing money to the ukraine. once againi providing money to the ukraine. once again i suspect there will be a vote straight down party lines and the democrats will once again be thwarted in their attempt to get new information introduced into this impeachment trial. when we are watching the live shot from the senate and we see the documents coming up, what are we watching? what you are seeing from the senate at the moment is in some ways we have got the prosecution under the fence setting out their cases —— and the defence. even though that's not officially supposed to have begun because we are getting involved in a whole debate about the rules for

this impeachment trial. however, actually because the american news networks are going wall—to—wall with this, many giving over all of their time to broadcast this impeachment trial on the first day of it, both president trump's lawyers and the house representatives who represent the democrats who are pushing for this impeachment, they are basically setting out their case and as a result during a lot of this we have had democrats introduced documents that have been produced before during these earlier hearings into whether or not president trump abused his power. we have also seen clips played of president trump and some others talking about what was going on inside the white house during interviews and some of those impeachment hearings that have already taken place. what we are now waiting for is the impeachment trial itself, and what will happen is over a 24—hour period that could be divided over three days, both the prosecution and the defence will

give their arguments about whether president trump did anything wrong. but we have already heard the arguments and ultimately it comes down to this... the lawyers for president trump say he didn't do anything wrong, he was acting well within his powers as president. the democrats believe he was abusing his position specifically to benefit him in the upcoming presidential election. i know you will be watching every moment closely. and we will of course continue to monitor the events live in this and that of course, we will be coming back to this shortly. but one noticable absence from washington is the president himself. donald trump chose to spend the first day of his trial several thousand kilometers away at the swiss ski resort of davos, where the world economic forum is being held. the big theme this year is climate change, and the president made his views on the subject clear. they were, perhaps unsurprisingly, in stark contrast to the views of the swedish climate activist greta thunberg, who's also at the forum. our correspondent,

james robbins, is also there. getting away from it all? donald trump has flown over 4,000 miles from washington to the alpine heights of davos, hoping to look more like a president on the world stage, less like a defendant back home. he's treading carefully on all the ice and snow — any fall here would look terrible. but will this gathering of the world economic forum, 5,000 feet up in switzerland, give an embattled president the high ground he craves? even without impeachment, he is way out of step with the main goal of this meeting — to do much more to tackle global temperature rise. but to embrace the possibilities of tomorrow, we must reject the perennial prophets of doom and their predictions of the apocalypse. they are the heirs of yesterday's foolish fortune tellers and i have them and you have them

and we all have them and they want to see us do badly, but we don't let that happen. being here today in switzerland and not in washington, the president may feel he is among friends — surrounded by more than 100 fellow billionaires — but, in truth, he is in a much more vulnerable and uncomfortable position than any of them. i'm a very big believer in the environment, we're now are doing extremely well in the united states, but what i want is to have the cleanest water, the cleanest air and that is what we are going to have and that's what we have right now. so, who are the world's biggest polluters? the us is the second largest producer of co2, accounting for nearly 15% of global emissions, but china is responsible for almost double that. the next biggest emitters of carbon dioxide are india, russia and japan, which produce another 15% of emissions between them. britain accounts for 1.1% of the total.

one of donald trump's fiercest critics is also here in davos. greta thunberg, teenage swedish activist, wants to hold everyone to account on behalf of her generation, accusing governments worldwide of empty promises. the fact that the usa is leaving the paris accord seemed to outrage and worry everyone and it should. but the fact that we are all about to fail the commitments you signed the fact that the usa is leaving the paris accord seemed to outrage and worry everyone and it should. but the fact that we are all about to fail the commitments you signed up for in the paris agreement doesn't seem to bother the people in power even the least. president trump will be using the rest of his time in davos to focus on one—to—one meetings with other world leaders. he will be discussing everything from trade disputes to the huge tensions in the middle east, but the long shadow of events in washington still seems to reach even to switzerland. james robbins, bbc news.

let's take a look at some of the day's other news. britain is considering the introduction of a sanctions regime against china over the incarceration of one million uighurs in detention centres in xinjiang province. a british foreign office minister told parliament that restrictions are being considered targeting individuals suspected of human rights offences. china says the camps are re—education centres. we have got, and we will be looking at introducing a sanctions regime. we consider our relationship with china to be an important one, but it is the basis and strength of that relationship, as i said earlier, that allows us to raise serious human rights concerns. the former head of the brazilian mining company, vale, and 15 other people are facing homicide charges over the collapse of an iron ore dam a year ago. 270 people died when the dam burst, near the brazilian town of brumadinho.

prince harry is threatening to take legal action over paparazzi photos taken of his wife, meghan. the duke and duchess of sussex issued a warning to the media after pictures of the duchess in canada were published in some newspapers and websites this morning. they were reportedly taken by photographers hiding in bushes with long—lens cameras. coca cola has said it won't stop using plastic bottles for its drinks because consumers still want them. it says using only aluminium and glass packaging could push up the firm's carbon footprint. coca cola produces about three million tonnes of plastic packaging a year.

let's return to the opening day of president trump's impeachment trial. adam schiff is on his feet. at the moment both sides are debating, at odds over how this should go forward. the president is being accused of abusing his power by soliciting ukraine to gain political advantage over his rivaljoe biden. we can guarantee that we will expect a fierce war of words as this trial unfolds over the next few days, but this is the live scene now from the us senate. we have had two votes rejecting amendments down party lines, expecting the next one soon. earlier i caught up with a political scientist and expert on us government. she is from the george mason university in virginia and she gave her initial verdict on proceedings.

the first day hasn't shown any particular fireworks. senators are essentially debating about the rules so there's nothing particularly exciting happening right now, but the democrats are primarily making their case, their appeal to the public. they want to get the public on their side to try to put pressure on their side to try to put pressure on some republicans who might decide to vote along democratic lines when things come to that, whereas republicans are largely focused on procedural issues and trying to get the matter over as quickly as possible. how important are the witnesses? because it could backfire for the democrats. there has been concern about that. from my point of view i can see that cutting both ways. the democrats would i think benefit from particular witnesses that they would like to call, particularly former chief of staff

mick mullaney and john bolton who by the president's account could provide incriminating testimony so the republicans would like to keep them out. if witnesses are allowed and the republican narrative regarding hunter biden is able to be called, that could undercut the narrative the democrats are putting forward. since the democrats need so many republicans to vote with them if this was going to have the effect of removing the president, they really won't be able to do that without some witnesses. given that these are senators, and of course they are now acting as a jury, can this ever be a fair trial in your opinion? i guess it depends on how we define fair trial. senators are

not allowed to speak, they have to submit questions in writing. the idea that this is a truth finding isn't really the case. what's mostly going on is a public affair where both sides are trying to get the public on their side to sway the public on their side to sway the public opinion to their case. still to come, why mindfulness matters when it comes to boosting mental health in the workplace. donald trump is now the 45th president of the united states, swanning on the steps of capitol hill in washington. it's going to be only america first. america first.

demonstrators waiting for mike gatting and his rebel cricket team were attacked with tear gas and set upon by police dogs. anti—apartheid campaigners say they will carry on the protests throughout the tour. they called him the butcher of lyon, klaus altmann is being held on a fraud charge in bolivia. the west germans want to extradite him for crimes committed in wartime france. there, he was the gestapo chief, klaus barbie. millions came to bathe as close as possible to this spot, a tide of humanity. it's believed by officials to have broken all records. this is newsday on the bbc. i'm mariko oi in singapore. i'm kasia madera in london. our top stories... the trial of president trump has begun in the us senate, with a big row over whether either side will be able to call witnesses.

health chiefs warn that a deadly new strain of pneumonia will spread beyond china as a case is confirmed in a traveller who'd just arrived in the us. the first case of the newly—detected virus, which originated in wuhan in china, has been confirmed in the united states. a traveller who arrived from china to seattle has been diagnosed with the coronavirus. six people are known to have died so far. the who is holding an emergency meeting on wednesday. gabriel leung, the dean of medicine at the university of hong kong, told me the new developments in the way the infection is spreading is posing a challenge. the research that we just finished 24—hours ago has now moved on. it is spreading that quickly. since we have looked

at this 2a hours ago, there has been a taiwanese case and now a us case exported from wuhan and that is what worries us quite a lot. what we've done is to take the overseas exported cases and then did a backward inference to estimate the likely pool of cumulative confirmed cases in wuhan itself, and then take that number to say looking at rail patterns, road patterns and air traffic patterns domestically within mainland china, what we are likely to have already seen or observed in terms of exporting outside of the borders of wuhan, to other places nationally and what might happen given the spring festival travel season, which actually began on january the 10th and lasts a0 days. that's really what our model has been trying to do, and we need to go back and now update it because of how things have moved so quickly.

as you say, the timing can't be much worse with the lunar new year celebrations and all the travelling, but there is the news that this can be transmitted between humans, does that change how governments and researchers should deal with it? indeed, and what we are trying to figure out as a global community is really how sustainable or how sustained human to human transmission has been and will likely be. secondly is really to try and prevent any super spreading events that is characteristic of most novel coronaviruses outbreaks like sars previously and because things have moved so quickly, there is hardly enough time to leave digest information and try to do the necessary scientific studies to get at some of those answers. of course, many of us here in asia

remember the sars outbreak, do you think asian governments have actually learned from that? i actually do think that china and other governments have learnt a lot from sars and indeed, having worked through sars in the scientific response, what i am seeing now is a really vast improvement from what had taken place 17 years ago. the level of transparency, openness and the scientific response and the public health decisive actions have really been quite impressive. now, the key question is, have all these actions and interventions been enough to contain this virus at the centre to wuhan itself, or will it spread wider nationally and indeed internationally into other epicentres? at the moment, the epicentre is still centred in and around wuhan and there doesn't appear to be other epicentres elsewhere despite the exported cases. so really, the next

few days and weeks are going to be absolutely critical. the dean of medicine at the university of hong kong speaking earlier. new analysis for the bbc suggests that in the uk, the cost of poor mental health in the workplace has increased significantly in just two years. one way companies are trying to deal with this is by promoting midnfulness at work. sarah toms reports from singapore. it's late afternoon here at the office of a billion veg, an app that reviews vegan food. usually it's a time when most people start to flag, but here the young staff are getting a wake—up call. oh, reach the ceiling. it sort of removes, like, obstacles when you're trying to expand an idea,

because you're not maybe nervous or like doubting yourself. you're in a space of calm to let it flow. the ceo of a billion veg has signed up for a full month programme. we tend to bring much more of our personal lives into the office. and i think that companies, the companies that you see that are succeeding in terms of areas like retention of employees, employee satisfaction are ones that are not shying away from that conversation, but that are really thinking about how do you make the workplace a great place for people so they can address their mental health and stress issues in a positive fashion. the trainer who runs these sessions shouting a jump in demand from companies in law, accounting, financial services and startups looking to keep their people focused, productive and happy. keeping your eyes closed. who feels hot? raise your hand. from my experience and what i'm seeing, it's driven by a need

to change workplace culture to retain younger talents that are just not staying in the workplace any more. studies show that companies are starting to take mental health more seriously. more people are reporting issues with anxiety and taking time off, and that's prompting companies to help workers feel less stressed. the corporate wellness market in asia is expected to be worth 7.4 billion us dollars by 2024, according to hrm, a human resources network. showing how stress and anxiety can put a dent in the bottom line, employers are also mindful that it makes financial sense. you have been watching newsday.

and i'm mariko oi in singapore. i'm kasia madera in london. this is a live shot of the us senate where the impeachment trial is under way. we are monitoring this for you. hello, we started this week off on a settled note, there's been quite a bit of sunshine around thanks to high pressure, which is with us again on wednesday. a subtle change where we begin to import some slightly less cold air from the atla ntic slightly less cold air from the atlantic which you will see on the chart throughout wednesday in the orange colours. today is going to be mainly dry but rather cloudy because we are picking up more moisture off the atlantic. many will start cloudy, and it looks like the skies will stay leaden throughout the day. the best of sunny spells will be across eastern scotland, and there could be the odd bright spell further south but a lot more cloud around. the winds will remain light
