i'm mariko oi in singapore, the headlines: or persons are commended to keep silent on pain of imprisonment. putting the president on trial. the impeachment of donald trump gets underway in the us senate, but so far the democrats aren't being allowed to call any evidence or witnesses. a trail with no evidence is no trail at all. it is a cover—up. the president himself is thousands of miles away in switzerland at the world economic forum. this is just

this isjust a hoax. that is this is just a hoax. that is the witch—hunt that has been going on for yea rs witch—hunt 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. good morning. it's nine am in singapore, one o'clock in london and 8pm in washington — where the impeachment trial of president trump has officially started in the us senate. not a lot of progress yet, though.

republicans who control the chamber, have rejected attempts by the democrats to obtain new documents and evidence. the latest, live, in a moment, but first, 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 serjeant—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 the veneer of 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 prosecutor is adam schiff, the democratic chair of the house intelligence committee. 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 is 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. we have the greatest economy over in our history. the trial will last for at least a week. there will be questioning. all of this will be conducted with the strictest rules of behaviour. but on the cable news networks, it is playing out 24/7 — and here it is mixed martial arts with seemingly no rules. this fight for public opinion is important, as donald trump eyes re—election later on this year. normally we would have a look at what is going on in the us senate, but we can't right now because the us senators have taken a break. they are having dinner at the moment. we can speak to chris buckler, though.

they have been at it for a while now, they voted three times, consistently on party lines. it will be good to catch up with what is going on thus far. they have to have a break to eat given what they have had to listen to. it has been an arguably dry session, because we do not have witnesses being cross—examined, instead, up until now this is about the rules of the trail and how this will be conducted, and democrats have been pushing very, very hard to try to get new evidence and information put into the public domain because up until now they have had subpoenas that have been issued for information from the white house simply refused, and therefore they haven't got information that they say they need for this trail. so up until now they have tried to introduce amendment

that would give them the right to ask for new documents from the white house that they haven't had the chance to see copy new documents also from the state department and the office of management and budget. all information that they believe is really important to this case. however, the republicans have a majority in the senate and therefore they have the ability to block that demand for those governments and up to now we have seen those votes go along party lines and that means those republicans have blocked the right for democrats to arc for new information from the white house. beyond that, when we get back from this break in the session, we will hear them now try to argue for another thing. they want to try to subpoena the acting chief of staff mick mulvaney to force him to give information. up until this point he hasn't agreed to those demands and i suspect we will see a vote again along party lines. they have been at

it for quite some time now, what are we expecting next? how many more of these amendments, votes, can we expect on this first day? we actually don't know, and this is just about getting the rules for the trial set up. this is a simple basis of working out how this will be conducted over the coming days. it does give you the idea up until this point from what we have heard from the prosecution and the defence of what their arguments are going to be. i don't think there will be anything that has come as a great shock to anyone who has watched this so shock to anyone who has watched this so far. they will be arguing that the president did nothing wrong, and the president did nothing wrong, and the democrats are going to say that he abused his position to try to influence the next election with is only a matter of months away try to remain president of the united states. it is also worth pointing out, if you look at the votes that have been along these republican and

democrat lines, it does give you an idea that although we are going to go through this trial, we do know the outcome. donald trump is going to remain president of the united states. chris will be monitoring events throughout the day when the senators come back, and important to state the senators are now acting as jurors when it comes to this particular trial. we are waiting for them to come back, they asked for a 30 minute break to go to dinner. we are monitoring that at the moment and we are told they will reconvene momentarily, so of course we will watch that. 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 us to have 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 c02, 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 critic 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 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 a important one, but 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 new pictures of the duchess in canada were published in some newspapers and websites. 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 3 million tonnes of plastic packaging a year.

let's return to the opening day of donald trump's impeachment trial. the debate is going strong in the us senate. both sides, democrats and republicans, are at odds over how it should proceed. the president is accused of abusing his power by soliciting a foreign power, ukraine, to gain political advantage. what is guaranteed as the trial unfolds is a fierce war of words. jennifer victor is a political scientist and expert on us government at george mason university in virginia, here's her verdict on proceedings. the first day hasn't shown any particular fireworks, where the senators are at the point where they are essentially debating about this,

so are essentially debating about this, so there is nothing particularly exciting happening right now. there will be notices that the democrat are primarily making their appeal to the public. they want to get the public 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 and trying to get the matter over and quickly as possible. when it comes to witnesses, how important is that? it could backfire for the democrat. there has been concern about that. from my point of view va ca ncy about that. from my point of view vacancy that cutting both ways. the democrats would benefit from particular witnesses that they would like to call, particularly former chief of staff mick mulvaney and john bolton, who by the president's

account could provide exculpatory information or testimony or not, so the republicans would like to keep them out. if witnesses are allowed and the republican narrative regarding hunter biden, joe biden‘s son, is able to be called as a witness, that could undercut the narrative that the democrats are putting forward, but since the democrats need so many republicans to vote with them if this was going to vote with them if this was going to have the actual effect of removing the president, that they really are not going to be able to do that without some witnesses. senators are not allowed to speak, they must submit their questions in writing. the idea that this is a

truth finding process is not really the case. it is mostly going on is a public affair where both sides are trying to get the public on their side and to sway public opinion to their case. you're watching newsday on the bbc. still to come on the programme: why mindfulness matters, when it comes to boosting mental health in the workplace. donald trump is now the 45th president of the united states. he was sworn in before several hundred thousand people on the steps of capitol hill in washington. it's going to be only america first. america first. demonstrators waiting for mike gatting

beyond china — as a case is confirmed in a traveller who'd just arrived in the us. staying with that story. 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 is the dean of medicine at the university of hong kong. he told me the new developments in the way the infection is spreading is posing a challenge. the research that we just finished 24 the research that we just finished 2a hours ago has now moved on. it is spreading that quickly. since we have looked at this 24—hour is ago there has been a taiwanese case and now a us case ported from wuhan and

thatis now a us case ported from wuhan and that is what worries us quite a lot. what we have done is take the overseas exported cases and did a backward inference to estimate the likely pool of cumulative confirmed cases in wuhan itself and then take that number to look at rail patterns, road patterns and air—traffic patterns mystically within mainland china, what we are likely to have already seen observed in terms of exporting outside the borders of wuhan to other places nationally and what may have happened given the spring festival travel season which began onjanuary ten and lasts a0 days. that is what our model has been trying to do and we need to now go back and update it because of how things have moved quickly. the timing could not be

much worse with the lunar new year celebration and all of the travelling but 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 really trying to figure out is a global community is really how sustainable, or how sustained, human to human transmission has been and will likely be. secondly, we are trying to prevent any super spreading events that are characteristic of most novel coronavirus outbreaks like sars and mers previously. things have moved quickly so we have not had time enough to die just the information and get the scientific studies for answers done. many of us here in asia remember the alp break of sars. have governments learn from that? # remember the outbreak of

sars. i think that china and other governments have learnt a lot from sars and having worked 33 in that scientific response, what i see now isa scientific response, what i see now is a vast improvement from what took place 17 years ago, the level of transparency and openness and the scientific response and the public health decisive actions have been quite impressive. the key question is have all these actions and interventions been enough to contain this virus epicentre 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 it does not appear to be other epicentres elsewhere, despite the exported cases. so really, the next few days and weeks

will be absolutely critical. and that was the dean of medicine from hong kong university. 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 around the world are trying to deal with this is by promoting mindfulness at work. sarah toms reports from singapore. it is late afternoon here at the office, usually it is the time when most people start to flag but here the young staff are getting a wake—up call. they chant the young staff are getting a wake-up call. they chant it removes obstacles when you are trying to expand an idea because you are not nervous or doubting yourself.

it is calm and you let it flow. the ceo has signed up for a four—month programme. we tend to bring much more of our personal lives into the office and i think that companies, the companies you see that are succeeding in terms of various such as employee retention and satisfaction, they are companies who do not shy away from the conversation. they think about how 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 ru ns positive fashion. the trainer who runs these sessions says she has seen a runs these sessions says she has seenajump in runs these sessions says she has seen a jump in demand from companies in law, accounting, financial services and start—ups seeking to keep their people focus, productive and happy. keep your eyes closed. from my experience of what i have seen, it is driven by a need to change workplace culture, to retain young talent that is just not staying in the workplace anymore.

studies show that companies are starting to take mental health more seriously. more people are reporting issues with anxiety, taking time off and that is prompting companies to help workers feel less stressed. the corporate wellness market in asia is expect to be worth $7.a billion us by 2024. expect to be worth $7.a billion us by 202a. according to the human resources network. and with studies showing how stress and anxiety can put a dent in the bottom line, employers are also mindful that it makes financial sense. let's try that on air! you have been watching newsday. yes, i think we should try. i'm kasia madera in london. a reminder of our top story: the impeachment trial of donald trump has begun in the us senate with republicans and democrats arguing

over the rules. these are live images now. we will be monitoring this over the course of these events here on bbc world news. more detailed analysis and background on our website. we started this week on a settled note with a bit of sunshine around, thanks to high pressure. but high pressure is with us again on wednesday. a subtle change where we begin to import some slightly less cold airfrom begin to import some slightly less cold air from the atlantic and you will see that on the ms charts here throughout wednesday. you can see those yellow and orange colours across the uk. so today will be mainly dry but rather cloudy because we are picking up more moisture of the atlantic and many of us will start cloudy and it looks like the skies will be led on through the day. best of any bright sunny spells tend to be eastern scotland here, sheltered from the south—west and the odd bright spell further south. the wind will remain light so

nothing to stir up the hour. it will be milder with temperatures in double figures for most, very mild in fact across the north—east of scotland given good spells of sunshine. and as we had through wednesday evening and overnight it stays cloudy with light wind, murky as well and if you get the odd hole in the cloud could turn chilly for most but because of the cloud cover it will be a frost free night. through thursday and friday, similar days with high pressure sticking around, light wind and it will have around, light wind and it will have a grey leaden sky with limited spells of sunshine. temperatures between seven and ii spells of sunshine. temperatures between seven and 11 degrees. significant changes into the weekend, high pressure varies near the continent and low pressure sta rts the continent and low pressure starts to portion of the atlantic could still be fairly cloudy across the board on saturday morning but as the board on saturday morning but as

the breeze continues to pick up from the breeze continues to pick up from the south—west it would be quite windy in the north—west and we will see some holes appearing in the cloud. a couple of showers around this wet front will bring outbreaks of rain to western scotland and northern ireland. that weatherfront spreads across the uk during saturday night and into sunday, a wea k feature saturday night and into sunday, a weak feature by the time it reaches the eastern side of the country, and no more than a band of cloud with a few showery bursts of rain. once that these it will be brighter for many with good spells of sunshine, quite blustery and this is a cool air masses well. about to be quite cold across the north and west of scotla nd cold across the north and west of scotland and northern ireland here so the showers will fall, winter and snow across the hills, nine or 10 degrees in the south—east. into the start of the following week it will turn more unsettled and a deeper area of low pressure could strong wind and spells offering. —— could bring strong wind and spells of

rain. i'm kasia madera with bbc news.
