this is bbc news with the latest headlines for viewers in the uk and around the world. us senators vote that the impeachment trial of former president donald trump is constitutional. he's accused of inciting the mob attack on the capitol building. the lead democrat says the case against mr trump is clear. you ask what a high crime and misdemeanour is under our constitution. that's a high crime and misdemeanour. if that's not an impeachable defence, then there is no such thing. for donald trump's lawyers, this trial is about freedom of speech and warning of tearing the country apart even further. this trial will tear this country apart perhaps like we have only seen once before in our history. a world health organization

investigation concludes coronavirus didn't originate from this lab in china, but can't say where it did come from. tough new quarantine rules for travellers to england in the effort to fight coronavirus — more testing, big fines and the threat of prison if they don't comply. hello, and welcome if you're watching in the uk or around the world. us senators have decided it is constitutional to proceed with the second impeachment trial of donald trump. the former president's lawyers argued he could not be tried as a private citizen, but senators voted 56—44 to continue with proceedings. the evidence against mr trump included a shocking film showing

the rioters storming the capitol on january the 6th. our north america editor, jon sopel, reports hear he, hear ye, hear ye... in the building where a policeman and four protesters lost their lives, where the trump—supporting mob ran amok month last month, donald trump today went on trial. on the question of whether donald john trump is subject to the jurisdiction of a court of impeachment... charged with inciting insurrection at the capitol, the most serious accusation ever levelled at an american president. the democratic party prosecutors setting out a vivid and searing video timeline. shouting. leading the democratic team is a congressman who'd buried his son the day before the riots, and he'd persuaded his wife and daughter to come to the capitol to witness american democracy and the peaceful transfer of power. she said, "dad, i don't want to come

back to the capitol again." _ of all the terrible, _ brutal things i saw and i heard on that day and since then, i that one hit me the hardest. that, and watching someone use an american flag pole, _ with the flag still on it, i to spear and pummel one of our police officers i ruthlessly, mercilessly. if donald trump is to avoid conviction, it won't be because senators will forgive or condone his behaviour. instead it will rely on a constitutional argument that you can't impeach a former president. the trump legal team, though, seem to be struggling to make their case. i don't know about off the top of my head, but each one of them, once there was the vacuum created that the greatest deliberative bodies, the senate of greece sitting

in athens, the senate of rome... the beating heart of us democracy is now padlocked and chained. there are miles of fencing and razor wire and literally thousands of deployed national guardsmen. this is fortress congress. beyond the heavily guarded perimeter, a few protesters are making their point, a far cry from what the trump—supporting insurgents found a month ago when they'd taken the former president at his word. we fight like hell, and if you don't fight like hell, you're not going to have a country any more. the trump defence is his speech was figurative and not literal. but the new president is trying to put maximum distance between himself and what's unfolding at the other end of pennsylvania avenue. the senate has theirjob. they're about to begin it. i'm sure they're going to conduct themselves well, and that's - all i'm going to have - to say about impeachment. thank you very much. since leaving office, donald trump has spent more or less

every day playing golf. but you can be sure that today he'll be watching, and closely. jon sopel, bbc news, washington. barbara plett usherjoins us from capitol hill. six republican senators joined with democrats in voting to find that the trial of donald trump is constitutional. what do you think that tells us about the likely final vote on whether or not to convict mr trump? i vote on whether or not to convict mr trum - ? ~ ., , vote on whether or not to convict mr trum - ? ~ . , , trump? i think that tells us the final vote is _ trump? i think that tells us the final vote is likely _ trump? i think that tells us the final vote is likely to _ trump? i think that tells us the final vote is likely to be - trump? i think that tells us the final vote is likely to be not - trump? i think that tells us the final vote is likely to be not to i final vote is likely to be not to convict donald trump because you need 17 senators to go along with democrats in order to do that. and this vote today on whether the trial is constitutional or not was a test case of how many republicans might be willing to go along with that. so six only suggests there is not going to be an appetite for going further

and actually voting to impeach. now the democrats have put forward quite a raw and emotional prosecution and they will continue in that vein throughout the next week to remind republican senators just how scared and shocked they were at the time and shocked they were at the time andindeed and shocked they were at the time and indeed at the time you did have some denunciation and criticism from republican lawmakers. but since then there has been a backlash against any criticism of president trump and so they have sort of pulled back from doing so. and it seems very unlikely that they would vote to impeach him. we cannot relate out completely but this vote today suggests that will happen. find completely but this vote today suggests that will happen. and what was the atmosphere _ suggests that will happen. and what was the atmosphere like _ suggests that will happen. and what was the atmosphere like they - suggests that will happen. and what was the atmosphere like they are i was the atmosphere like they are today when that shocking video was played recounting the events of january the 6th? because you are sitting there talking to us in effect from the crime scene itself, and the lawmakers were witnesses to what happened.

and the lawmakers were witnesses to what happened-— what happened. yes, and that's what makes this impeachment _ what happened. yes, and that's what makes this impeachment trial - what happened. yes, and that's what makes this impeachment trial so - makes this impeachment trial so unique, that this is the crime scene and that thejurors unique, that this is the crime scene and that the jurors were also the witnesses and to some degree the victims because they came under attack, and that video was designed to pull all the strings to remind them of how terrifying and horrifying and shocking it had been, though scenes of violence selected to bring across that point. and you heard mr raskin�*s very emotional testimony as well about how afraid and upset his family was and we've also heard about members calling home and saying they were 0k also heard about members calling home and saying they were ok or perhaps this could be about so it was a very emotional recounting of it. it's been several weeks now, and perhaps that had died down a little bit but it is true that these lawmakers are still processing that at some level and this has brought it to the for once again.— it to the for once again. barbara come alive _ it to the for once again. barbara come alive from _ it to the for once again. barbara come alive from capitol - it to the for once again. barbara come alive from capitol hill, - it to the for once again. barbara i come alive from capitol hill, thank

you. scientists from the world health organization investigating the origin of the pandemic say coronavirus is "extremely unlikely" to have leaked from a chinese laboratory, but they were less clear about where the virus did come from. they presented their findings after travelling to wuhan, where the first case of coronavirus was recorded in december 2019. our correspondentjohn sudworth reports from there. it's one of the most important questions of our time — where did the virus come from? but the scientists had more to say about what they hadn't found than what they had. it has not been possible to pinpoint any animal species as a potential reservoirfor this disease, and it doesn't look like there was wide circulation of the virus in any animal species in the country. china's wet markets were once thought to be the prime suspect, where the virus was most likely to have jumped from

animals to humans. this market, linked to some of the earliest cases, was a particular focus, but with animal tests said to be negative, the team has come up with another theory — frozen food. and an idea china itself has been promoting in recent months. the virus, they suggest, may have travelled to wuhan on imported frozen produce. the who arrived here insisting this was going to be all about the science, and yet signs of the politics have been there every step of the way, from the wrangling about access and timing, from the team's reliance not on its own investigation, but on data provided by china. the questions about how independent these findings really are from china's own narrative are unlikely to go away.

locally, it's a narrative that's taken hold. on the banks of the yangtze river, this fisherman says he's heard that the who is in town. "it's impossible for the virus to originate from here," he tells me. "it came from overseas." this is a press conference. i'm allowed to ask questions. after the press conference, chinese officials tried to stop any interviews. concerned, perhaps, that they might lose control over such sensitive issues, and few more sensitive than this. some scientists believe the virus could have leaked from this laboratory, known to have been experimenting on coronaviruses. but china had little to fear from the scientists we were able to speak to. some have been calling the lab leak theory a conspiracy from the start. given that this report rules out a lab leak, isn't your credibility on that somewhat undermined by the fact that

you were ruling it out before you even came here? a very large group of experts have looked at this, they've been to the various labs around the region and talked to people, asked critical questions, got critical answers, and they've come to their conclusion, and i have as well. and what they say is it's extremely unlikely, and that stands alone. covid devastated this city first and, for now, its origins remain almost as much as of a mystery as before. the uk government has unveiled tough new quarantine rules for anyone arriving in england from outside the uk. visitors from 33 hotspots will have to pay $2400 to stay in special quarantine hotels for ten days. and all other arrivals must self—isolate or face fines and even jail time. the measures are aimed at keeping coronavirus variants out of britain. all travellers are already required

to have a negative covid test. here's our transport correspondent caroline davies. when liz travelled to portugal in september when her father died she did not know would be facing ten days in a quarantine hotel she came back. she can't return until her father's house is sold, which means she will have to pay £1750 to quarantine in a hotel. it's extortionate. i think it would be really depressing on top of being pretty miserable, anyway. we're coming back, not from a nice holiday, but from grieving for a lost one or ill families, etc. so i think this needs to be considered in how they treat people. today's announcement introduces further restrictions on international travel, including higherfines and potential prison sentences. i know that most people have been doing their bit,

making huge sacrifices as part of the national effort, and these new enforcement powers will make sure their hard work and sacrifice isn't undermined by a small minority who don't want to follow the rules. under the government's policy, only those arriving from countries on the uk's red list will need to quarantine in a hotel, but labour want the policy to apply to arrivals from every country. he hasn't announced comprehensive quarantine controls at the borders, i so why, then, when over halfl the countries where the south african variant has been identified, why are over half of them not - on the so—called red list? holidays are currently illegal, but it seems many of us are already thinking about the summer sun. a holiday firm have said they have nearly had 3 million bookings for the summer, and many in the industry are already viewing the season as vital for their survival. many in the airline and airport industry are worried. the more restrictions that are added

on, they think it could take longer for those to be removed, particularly in time for the summer. we just don't know where we're going to be over the next few months. it's just rapidly changing, but we know there's a huge amount of pent—up demand for people to go away this summer. but the policy won't be the same everywhere in the uk. while england and wales will only require arrivals from banned countries to quarantine in hotels, scotland will require all international rivals to do so. the uk government has only committed to adopting this for travellers returning from red list countries. we know that is not sufficient, and we have therefore gone further. in northern ireland, discussions are still ongoing. the travel industry can't be ramped up overnight. it needs some warning as to when international travel might start again. both it and potential passengers are waiting to see whether summer travel can go ahead. more now on the impeachment trial

of former president trump, and in the last hour, the senate has voted that the proceedings are constitutional, which means it will continue tomorrow. but what does the general public make of it all? let's go through this with anthony salvanto, director of elections and surveys at cbs news. what are americans making of it all? nice to talk to you. we found going into the trial that a 56% majority of americans said they would look to the senate to get a conviction. now is not a coincidence that that 56—44 split on conviction looks a lot like the election results and the reason for that, the election results and the reason forthat, i the election results and the reason for that, i can show you on the screen, is there are sharp party breaks in views on this. we find large majorities of democrats saying this and it ought to convict but the bulk of republicans, of course the former president's own party, saying the senate ought not to give it. now having said that, there are some

republicans, though they are outnumbered, who seem to be open to the idea of a conviction and that is an important part as we go forward and look at devices such as they are, if they are very many, among republicans. so are, if they are very many, among republicans-_ republicans. so it seems that this vote we sought — republicans. so it seems that this vote we sought today _ republicans. so it seems that this vote we sought today on - republicans. so it seems that this vote we sought today on capitol . vote we sought today on capitol hill, where 56 senators voted the trial was constitutional and 44 voted it was not, it's all because of public opinion.— of public opinion. some of it is. certainly some _ of public opinion. some of it is. certainly some of— of public opinion. some of it is. certainly some of it _ of public opinion. some of it is. certainly some of it is - of public opinion. some of it is. certainly some of it is in - of public opinion. some of it is. certainly some of it is in one i of public opinion. some of it is. certainly some of it is in one of| certainly some of it is in one of the things that is interesting here is you look at the republicans and some of them did go forward with this as constitutional but the bulk of them did not. and i want to look at the reasons behind that. as you mentioned, public opinion, one of the things we look at and the survey was asking republicans how important is it to you for the party to be loyal to donald trump? and we saw large numbers, almost half, saying it was very important for them for

the party to stay loyal to the former president and another quarter orso former president and another quarter or so saying at least somewhat important. and that starts to define these breaks. you see a preponderance of republicans looking for that loyalty and then a smaller number really say not that important and move on and that reflects a lot of the debate and discussion that you saw about the future of the republican party and even a congress you have seen the last couple of weeks. �* ., , , , weeks. and the former president is loomin: weeks. and the former president is looming large _ weeks. and the former president is looming large over _ weeks. and the former president is looming large over the _ weeks. and the former president is looming large over the straw. - weeks. and the former president is looming large over the straw. he . weeks. and the former president is looming large over the straw. he is there in florida. he is playing a lot of golf. but what about his id or his threat to form a new party? walking can you tell us about what support that might have? i’m walking can you tell us about what support that might have?— support that might have? i'm glad ou asked support that might have? i'm glad you asked because _ support that might have? i'm glad you asked because we _ support that might have? i'm glad you asked because we have - support that might have? i'm glad| you asked because we have people that. of course it is somewhat speculative but it does speak to a point of just speculative but it does speak to a point ofjust how much the party and his partisans want to stay with him, so we asked would you join a party if donald trump started one? and we see a third of republicans say it yes right off the bat. and another

almost a third said they would at least consider it. so here again you see that split where over two thirds of republicans at least consider something like this but again it is speculative but it speaks to the point of them being and looking for loyalty to him in that remaining third who say no that they would not and that really is consistent across these breaks that we see among republicans. these breaks that we see among republicans-_ these breaks that we see among republicans. anthony, that great screen, thank _ republicans. anthony, that great screen, thank you _ republicans. anthony, that great screen, thank you for _ republicans. anthony, that great screen, thank you forjoining - republicans. anthony, that great screen, thank you forjoining us. | screen, thank you forjoining us. thank you. a new survey carried out by imperial college london suggests global confidence in the coronavirus vaccine is increasing. in november last year, people in 15 developed countries were asked if they would take the jab were it available next week. they were asked the same question injanuary. the number of people willing to take the vaccine increased everywhere, except in four countries. the uk and france saw the biggest increases. confidence almost doubled in both countries.

but injapan, south korea, singapore and australia, confidence went down compared to last year. but that doesn't tell the whole picture, of course. france, for example, still had the lowest number of people willing to take the vaccine. let's bring in someone who contributed to the research, professorjulie leesk from the university of sydney. thank you for being with us. if we start with the good news, why do you think it is that there is so much more confidence in taking the coronavirus vaccine and there was? i think there is probably a number of factors here and of course there is a large disease burden at present. but there is also the fact that that the programme is being rolled out in some of these countries, so it is becoming a reality and you're probably seeing people now forming their intentions to have the vaccine and going ahead with it. and therefore it is strengthening their

attitudes and warmth, i guess, towards the vaccine. in attitudes and warmth, i guess, towards the vaccine.— attitudes and warmth, i guess, towards the vaccine. in france was somewhere _ towards the vaccine. in france was somewhere with _ towards the vaccine. in france was somewhere with low _ towards the vaccine. in france was somewhere with low overall - towards the vaccine. in france was somewhere with low overall trust i towards the vaccine. in france was | somewhere with low overall trust in the coronavirus vaccine even though it had increased. why such little trust in the vaccine in france? france is a complex situation. so we see lower perceptions of vaccine safety for childhood vaccines as well in france. there are many issues with trust in government in france, and there also appears to be emerging this partisanship around vaccination such that if you are leaning more towards the far right, then you are more than twice as likely to not intend to accept the covid—i9 vaccine. so i think there is complex political and historical issues that are occurring for france

that are not subject to one single explanation. that are not sub'ect to one single explanation.— explanation. and what about the situation in _ explanation. and what about the situation in australia _ explanation. and what about the situation in australia where - explanation. and what about the situation in australia where you | situation in australia where you are? you've had these very strict coronavirus lockdowns. what impact if any has it had on people posit willingness to take the vaccine? interesting in australia. we are seeing a slight reduction in intention is to have the vaccine here. but overall they are quite high at, so in previous surveys of 27 countries, we ranked third on that list of proportion of people intending to have the covid vaccine. we had seen a slight decline and i think what is happening now is we have not started out that vaccine programme yet in australia. it is to start at the end of this month. and so there is now saturation news coverage about the vaccine and we are looking at every single event, little debates around whether we have got the most effective vaccines coming to australia. there is news

from norway for example about vaccine adverse events and they are all hitting the news people are starting to shape their decisions now. i think we will see an increase in support for vaccination again in australia. �* , , , australia. and “ust briefly, given the australia. and just briefly, given the coronavirus _ australia. and just briefly, given the coronavirus vaccines - australia. and just briefly, given the coronavirus vaccines are - australia. and just briefly, given the coronavirus vaccines are so i australia. and just briefly, given - the coronavirus vaccines are so new, argue encouraged by what you see in terms of people profit willingness to take them? i terms of people profit willingness to take them?— to take them? i am really. think about it, these _ to take them? i am really. think about it, these vaccines - to take them? i am really. think about it, these vaccines have - to take them? i am really. think l about it, these vaccines have been developed in record time. it is very novel for people to deal hesitantly —— hesitancy about a new programme and little on this one in this volatile environment. however what we have here is really such a miracle in many ways. that six months ago we were not sure that we will be able to get vaccinated and now we have roll—out happening among now we have roll—out happening among now hundreds of millions of people. this is really a remarkable aspect of my medical miracle in many ways. and i think that as people start to

take the vaccine and see it rolled out and see it is safe and effective enough, they will start to become more confident in the vaccine. professor, thank you so much for joining us. professor, thank you so much for joining us— a space probe launched by the united arab emirates has entered orbit around mars, a first for the arab world. only four other space agencies have made successful trips to the red planet. the probe will spend the next two years studying the atmosphere. our science correspondent rebecca morelle has more. music. mission accomplished — the united arab emirates has made it to mars. after a tense wait in the control room, celebrations. as a signal sent from their spacecraft millions of miles away beams in.

it's like the weight of seven years has been lifted from my shoulders on arriving to mars. i'm truly looking forward to the scientific discoveries. abd i truly hope this mission will impact an entire generation to strive for things that are even bigger. the spacecraft is called hope and has pulled off a make—or—break manoeuvre, firing its thrusters so it's captured by the gravitational pull of the red planet. the hope mission will see more of mars than we've ever seen before. its spacecraft has an elliptical orbit, swinging in closer and then much further away. at its closest, its flight path matches the rotation of mars, so it hovers over some key features, like olympus mons, the biggest volcano in the solar system. at its furthest point, the planet spins beneath it, giving it a much wider view. this means it will see almost all of the planet, both from close—up and from far away. arriving at the red planet is a huge leap for the uae.

until now, the nation has only sent satellites into earth orbit. the spacecraft will study the martian atmosphere. the mystery of how mars transformed from a planet like earth, to the dry, dusty world it is today. reaching mars isjust halfway through the journey. we still have to do the science work, we still have to collect data and still have to come up with new discoveries about mars. and this mission is again just a starting point. for the united arab emirates, they have made history, establishing themselves as a new space power. but they're not the only ones heading to mars. tomorrow, china's spacecraft arrive, thennext week, nasar�*s rover is due to land. the red planet is about to get busy. before we go, one of the original members of the supremes, mary

wilson, has died at the age of 66. the all black group broke barriers and is famous for his singles like baby love, which is music to define the 60s. thank you for watching. hello. we're only in the middle of this cold snap. it may last until the weekend. in the short—term, snow showers continuing to affect eastern areas. that amber warning in central and eastern scotland for a while. for the rest of the night, it's mostly fleeting flakes and wind. and needless to say, a freezing cold wednesday morning. —3, -4 degrees in city centres. tomorrow, once again, snow showers affecting mostly eastern areas of the uk. in fact, many western areas clear, some sunny spells there, sparkling weather looking out to the irish sea. temperatures around freezing. a little above and a little below depending on where you are on wednesday. later on wednesday,

the winds are going to ease. the showers are going to become less frequent, the snow showers. the reason is high pressure is building, high pressure tends to settle things down. and with clearing skies and winds falling light, the temperatures are going to drop like a stone because of this cold, extensive scandinavian high. and it will be the coldest morning of the week. temperatures in city centres —7 degrees, —8 in kew gardens could make it the coldest morning in around a decade or so. super cold morning on thursday with some sparkling, crisp weather a little later on. the weather is starting to change. out towards the south west, you'll notice clouds building. a bit of rain out to sea, some snow reaching parts of ireland. it still very cold across many parts of the uk, around freezing or even below. friday, the cold weather, the cold easterly wind still wins. that mild air tries to push in, but it really struggles. in fact, it's no longer

an easterly wind, it's more of a dry south—easterly. it undercuts any weather fronts trying to come in from the west, and that dry wind evaporates the weather front. dry and cold on friday across most of the uk. a battleground come the weekend. the milder air tries to push in off the atlantic. this is a very persistent south—easterly at this stage. the indications are in computer models as we go through the weekend into sunday, it's increasingly likely that that mild air might eventually win.
