and the duchess of sussex launches a scathing attack on a british tabloid after winning her high court privacy battle. hello and welcome if you're watching in the uk or around the world. and i do hope you stay with me for the latest analysis from here and right across the globe. we begin in the us, where house democrats have made theirfinal push in the impeachment trial of donald trump. their main argument today is that the rioters acted at the direction of mr trump himself. and they warned that he could promote new violence if he's not convicted. the prosecution relied again on emotionally—charged videos, to highlight what they described

as the "harm" caused by his words. they will need to sway 17 republicans to convict mr trump of a single charge of incitement of insurrection. here's a bit of what we heard today. onjanuary 6, we know who lit the fuse. president trump's lack of remorse and refusal to take accountability after the attack poses its own unique and continuing danger. this attack on our elections, - on the peaceful transfer of power from one president to the next, didn't even happen during - the civil war, but it did justl happen because of the cold, calculated and conspiratorial acts i of our former president, donald j... trump declared his conduct totally appropriate. so if he gets back into office and it happens again, we'll have no—one to blame but ourselves.

let's get some reaction from our washington correspondent, barbara plett usher, whojoins washington correspondent, barbara plett usher, who joins us now. barbara, it has been fascinating viewing, so what did you make of the way they presented their case today? what were they really focusing on? you remember in the very graphic video they show yesterday, re—enacting or showing the anatomy of the riot and forcing senators to relive that trauma as part of their case. today, it was very much focused on piece by piece talking about mr trump's role and intent during the attack, because to establish or to prove incitement, you have to show intent, until it theyis you have to show intent, until it they is they showed the history of mr trump, they is they showed the history of mrtrump, that they is they showed the history of mr trump, that he had a history of inciting violence. they used his, for example, some of his statement at rallies where he condoned

violence against protesters. they also, and quite an important segment, showed how supporters believed that they were following mr trump's orders and they used to their supporters own words and video and audio to demonstrate that. and then another big part of their argument was that mr trump did not show remorse for what happened, and that he said his behaviour was totally 0k, therefore if you was not punished, that he could continue to do harm and that presidents who came after might also feel they did not have impunity and therefore he should be impeached. those were their main arguments and they wrapped up by saying that they had proved incitement and that it was for the good of the country and the good of american democracy that he be impeached. find good of american democracy that he be impeached-— good of american democracy that he be imeached. �* , ., be impeached. and i suppose from the re - ublicans be impeached. and i suppose from the republicans point _ be impeached. and i suppose from the republicans point of _ be impeached. and i suppose from the republicans point of view, _ be impeached. and i suppose from the republicans point of view, tomorrow, l republicans point of view, tomorrow, they are really likely to push this angle of testimony and evidence, aren't they?— angle of testimony and evidence, aren't the ? ~ ., , , ., aren't they? what they started with was to say that _ aren't they? what they started with was to say that the _ aren't they? what they started with was to say that the trial _ aren't they? what they started with was to say that the trial is - was to say that the trial is unconstitutional, but the senate voted that down. that is a

procedural argument, so we will see where the lawyers pick that up again, but what they have said is that mr trump was speaking figuratively when he used that incendiary language at the valley. it was only figurative speech, it was just that his supporters took literally. he did not mean that literally. he did not mean that literally and that, anyway, he has the right to free speech. that's protected under the constitution because it was political talk, so that will be a big part of their defence and that he also did not mean for the supporters to go undetected capital, and they will probably argue the democrats have not adequately proved that that was his intent, boy understand that they're not going to take very long making the argument. they're gone to wrap up probably in one day maybe only in a few hours, and that suggests amongst other things that they feel they do have the republican votes to acquit mr trump. 0k, barbara plett usher, we will leave it there for now, but think you very much for that. thank you.

with me now is kathryn brownell, professor and university faculty scholar in the department of history at purdue university. thank you forjoining us here on bbc news. what did you make of the impeachment managers presentation today, in fact, so far?— today, in fact, so far? thank you so much for having _ today, in fact, so far? thank you so much for having me. _ today, in fact, so far? thank you so much for having me. i _ today, in fact, so far? thank you so much for having me. i think - today, in fact, so far? thank you so much for having me. i think so - today, in fact, so far? thank you so much for having me. i think so far. much for having me. i think so far that the house impeachment managers have done a really effective job in presenting the hard evidence. they have laid out the facts, the timeline, the very concrete link between trump and the insurrectionists and they've also put that into that broader context about notjust put that into that broader context about not just what put that into that broader context about notjust what happened on january 6 but in the months, even the years, beforehand, and then really talking into his response as well. �* ., ., ., ., ., well. and a lot of the video that we have been seeing _ well. and a lot of the video that we have been seeing has _ well. and a lot of the video that we have been seeing has been - well. and a lot of the video that we have been seeing has been very . have been seeing has been very powerful. what do you think of the way it's been presented, because they had been concerns that the delegates might put on a somewhat

hollywood style version of that video? i hollywood style version of that video? ~ ,., ., video? i think the power of the presentation _ video? i think the power of the presentation is _ video? i think the power of the presentation is in _ video? i think the power of the presentation is in the - video? i think the power of the | presentation is in the evidence, video? i think the power of the - presentation is in the evidence, and not any glitz and glamour surrounding it, and that is why it is so effective. and this is actually been true in the past. thinking about the investigation into watergate, these televised hearings, and that not so many people to understand the gravity of theissues people to understand the gravity of the issues at stake —— that got so many people. and ultimately to see that richard nixon was involved in wrongdoing, because it focused not on the performance of one senator, but it focused on presented the evidence, establishing that clear timeline. and i think that that same dynamic is very much playing out right now. it is the power of the evidence, the videos, the tweets, the response to the insurrectionists to trump's tweets in real—time, and ultimately his inaction, and so the timeline and all of these concrete facts, that is what is powerful in

the presentation, not any thing about glitz and glamour. how the presentation, not any thing about glitz and glamour. how do you think it will be _ about glitz and glamour. how do you think it will be viewed, _ about glitz and glamour. how do you think it will be viewed, though, - think it will be viewed, though, when we compare what is going on in terms of... we need those 17 republicans to cross to the democrat side on this, but there is the chance that politics is going to get in the way. how will that ever to the way americans are viewing all of this? social media and the audiovisual is part of our culture now? ~ , ,., , �* ~' audiovisual is part of our culture now? �* , �* ~' ., now? absolutely. and i think that re . ardless now? absolutely. and i think that regardless of _ now? absolutely. and i think that regardless of what _ now? absolutely. and i think that regardless of what happens, - now? absolutely. and i think that regardless of what happens, this | regardless of what happens, this process of impeachment in the trial itself is really important in bringing all of this concrete evidence and all of these facts, and writing them into the historical record and preserving them, and that is especially true with all of the evidence that has been compiled via social media and all of the social media posts of those people who were involved, all of these videos that have been introduced. and i will say that after four years of rampant

misinformation coming out of the trump white house, this trial is really forcing the country to confront the facts, and whether or not the senate holds trump accountable for his actions, the document tree record is there for the public to access, both now and in the future.— the public to access, both now and in the future. 0k, kathryn brownell, thank ou in the future. 0k, kathryn brownell, thank you very _ in the future. 0k, kathryn brownell, thank you very much _ in the future. 0k, kathryn brownell, thank you very much indeed. - in the future. 0k, kathryn brownell, thank you very much indeed. thankl thank you very much indeed. thank you. you're watching bbc news. a drug that is normally given to people with arthritis could help in the treatment of covid—i9. a major trial shows that when tocilizumab is combined with the steroid dexamethasone, it can cut by up to half the number of covid patients dying in hospital. our medical editor fergus walsh reports on the trials that were carried out here in the uk. searching among existing medicines for any that can treat covid has been a huge task. first, there was dexamethasone.

now, there's tocilizumab. together, they can dramatically improve survival for patients on oxygen. compared with a year ago, when we really did not know how to treat this disease, we now have two treatments — they both act on the immune system. dexamethasone and tocilizumab, put them together and we've reduced the risk of death by a third or even as much as a half in the sickest patients. that's great news. dexamethasone, a steroid, costsjust £5, whereas the arthritis drug, tocilizumab, at least £500 per patient. but that's still far less than the £2,000 a day cost of being in icu. this therapy looks like it keeps people out of the intensive care unit, so they never need to meet

people like me, which can only be a good thing. so, as well as improving survival, it actually will decrease the number of people who need to come to intensive care, which is fabulous. there's understandably a huge focus on preventing coronavirus and vaccines, but for those with covid, it is treatments like dexamethasone and tocilizumab which will save lives now. they need the research, so ijust signed up for them. lawrence spent several days in intensive care at addenbrooke's hospital in cambridge, but now has his bags packed, ready to go home. he's one of tens of thousands of covid patients taking part in nhs trials. if nobody's willing to try, you're back to square one again, aren't you? if nobody's going to do anything. last month, nhs hospitals treated more than 100,000 covid patients. that's around one in three of all those admitted since the pandemic began. covid remains a brutal disease, but the chances of surviving it are improving. fergus walsh, bbc news.

china has banned bbc world news from broadcasting on its territory. china state media says the bbc was responsible for what was called a "slew of falsified reporting" on issues including xinjiang and china's handling of coronavirus. they go on to say that "fake news" is not tolerated in china. last week, we broadcast detailed accounts of muslim women who said they had been systematically raped in so—called re—education camps in xinjiang. the bbc says it's disappointed with the decision and in a statement said that... 0ur diplomatic correspondent james landalejoins me now from west london. hi there, james. was this expected? i do nothing this comes as any great

surprise. as you said in your introduction, china has expressed its displeasure for some time now at reports made by the bbc, notjust about the situation in hong kong in the imposition of the security law there but also very much specifically the bbc�*s coverage of the allegations and reports of human rights abuses in xinjiang, so there is a general concern about the bbc within the chinese authorities in general, but more specifically, i think the chinese were retaliating for the decision by the british communications regulator 0fcom recently to revoke the licence of cgtn, the chinese satellite english slang was broadcaster in london, because of its links to the commonest party in china. and ethic this is retaliation for that. how has the british _ this is retaliation for that. how has the british and _ this is retaliation for that. how has the british and other world governments responded to this? hat governments responded to this? ijrrt surprisingly, the british government

has been pretty condemning in the tweet. dominic raab has said... and over the atlantic, the us state department was equally concerned, expressing his concerns also about the scale and the impact this will have on media freedom. we absolutely condemn the prc's decision to ban bbc world news. the prc maintains one of the most controlled, most oppressive, least free information spaces in the world. it's troubling that as the prc restricts outlets and platforms from operating freely in china, beijing's leaders use free and open media environments overseas to promote misinformation. we call on the prc and other nations

with authoritarian controls over their population to allow their full access to the internet and media. james, what are the likely consequent is moving forward? in practical terms, consequent is moving forward? in practicalterms, it consequent is moving forward? in practical terms, it is not clear what effect this will have in china. already it is very hard to get bbc content in china. you cannot see the bbc website, you cannot get the bbc app. a lot of bbc television only got through to international hotels in place like that. the practical applications are harder to determine for 70 longer—term... this will... there are various depute. what this will do is add growing fuel to organs within the british parliament for the uk to develop an even tougher line on china in the weeks and months to,. {lila tougher line on china in the weeks and months to,.— tougher line on china in the weeks and months to,. 0k, james landale, thank ou and months to,. 0k, james landale, thank you very _ and months to,. 0k, james landale, thank you very much _ and months to,. 0k, james landale,

thank you very much indeed. - ten years ago today, egypt's president, hosni mubarak, was forced from office after weeks of demonstrations in cairo. it was a seismic moment in the middle east and helped encourage other uprisings across the region. but hopes that people power would transform egypt were short—lived. the military seized control and have imposed a much tougher police state than the one mubarak led. 0ur middle east editorjeremy bowen looks at the decade that's followed mubara k�*s fall. nobody who was there will forget it. the night egypt's president hosni mubarak stepped down, and tahrir square in cairo erupted. it tookjust 18 days of protest, danger and death to remove a president who had been an immovable fixture in the middle east since the 1980s. the people have taken on a brutal police state and overthrown an authoritarian leader who appeared to be in control. their achievement will

change the middle east. it did... ..but not in the way that the people who cleaned up the square the next morning, symbolically reclaiming their country, were hoping. mohammed suliman, now a political analyst in washington, was a 19—year—old protester. we did, we did believe that this was the moment in history where arab people could finally be free, and be the master of their own fate. but egypt's revolution lacked leaders. more powerfulforces did not. mohammed morsi, the muslim brotherhood's candidate for president, beat the military�*s. as egypt lurched between crises, the generals seized power back in 2013. gunfire

at least 2,500 people, almost all civilians, many of them muslim brotherhood supporters, were killed in the next seven months. in the last couple of minutes, there was fire into the walljust above where we were. all this is a sign of the danger in the streets in cairo, about the divided nature of society. the president abdel fattah el—sisi, a former general, has jailed tens of thousands of opponents of his regime. among them, members of this family, prominent human rights campaigners. alaa abdel fattah was tortured during years in sisi's jails. he is still a prisoner, along with his sister, sanaa. she shouts anothersister, mona, live streamed this video

after sanaa was arrested. both women were beaten. their mother, laila soueif, says it's much worse for thousands of other egyptians. worse than under mubarak? much worse than under mubarak. i mean, all of the things that i'm saying used to happen during mubarak's time, but the scale is completely different. is there something that the west should be doing now? i know that western politicians are selling their people the line that they have to back singular regimes in the area, because it is the only way to achieve stability. now, this is their alibi. it's not true. british people should hold their government accountable for what it's doing, for how it's, you know, working for the benefit of arms and energy companies, rather than people. in cairo, and across the middle east, millions don't want

another decade of upheaval. they wantjobs. young people drove the 2011 uprisings, angry about corruption, repression and unemployment, still the highest in the world. in egypt, a third of under—30s arejobless. the old grievances of 2011 still exist, but the hope has been crushed. history shows that repression works, until desperation overcomes fear, and then it doesn't. jeremy bowen, bbc news. the head of the tokyo 0lympics committee, yoshiro mori, is expected to resign after making widely criticised sexist remarks. there's been growing anger injapan and abroad after mr mori complained that women were annoying and spoke too much in meetings.

0ur tokyo correspondent, rupert wingfield—hayes, said there's pressure on him to go. i think initially, when mr mori made his initial policy for his very clearly successor mark stirring in the living board meeting, there was a sense he might write this out. politicians and the japanese a limit committee and the international olympic committee came behind him, and the japanese government said, look, he has apologised, he has withdrawn his comments, this matter is now closed. and since then, the public outreach as early grown and grown. there's been an online position with 150,000 signatures. 0ther position with 150,000 signatures. other things that happen as often as we've seen hundreds of volunteers, limit and paralytic volunteers, saying they would not take part, they would quit their positions as volunteers if mr mori remained —— 0lympic volunteers if mr mori remained —— olympic and paralympic for high—profile people injapan and around the world criticising him, including superstars like for

example naomi 0saka. but i think what we have seen crucially is the chairman of toyota motor corporation, one of the biggest corporations injapan and biggest sponsors of the olympics, he came out and added his voice, saying that the remarks were unacceptable and not fitting with toyota's values, and ethic when you got one of your major sponsors, the head of one of your major sponsors, saying, i don't want to see you any more, that was probably the final strong. and we have heard today, leaks japanese media, that this is going to happen on friday, that mr mori is going to go. that was rupert wingfield hayes. meghan markle, the duchess of sussex, has won her two—year legal battle with a british tabloid newspaper over the publication

of a letter she wrote to her estranged father, thomas markle, after her wedding to prince harry. today, the high court ruled that the duchess had had a reasonable expectation that the letter would remain private. this report from our royal correspondent, nicholas witchell, contains flash photography. this is a significant victory for the duchess of sussex. meghan, strongly supported by her husband, prince harry, has shown herself to be absolutely determined robustly to defend her right to privacy. this case began after the mail on sunday published lengthy extracts from a letter she'd written in late 2018 to her estranged father, thomas. meghan's lawyers had told the high court that the letter was a heartfelt plea from an anguished daughter. they applied for something called a summaryjudgment, a judgment without a full trial, on the basis, they said, that the mail on sunday had no real prospect of success. and thejudge agreed. mrjustice warby examined the evidence and found...

..he said. meghan has also won on the separate issue of copyright infringement, but privacy is the one that really counts. in a statement, she spoke about what she said were the tactics of the mail group's newspapers. "for these outlets, it's a game", she said. "for me and so many others, it's real life, real relationships and very real sadness. the damage they have done and continue to do runs deep." the mail on sunday's publishers said they were very surprised by the judgment. they said they would decide in due course whether to lodge an appeal. and, first reaction from media lawyers... this is a significant victory because of who she is. the mail had published a series of articles around meghan and her life and her private life and i think this was the tipping point for her. i suspect it should have quite a sobering impact on sections of the media who think that celebrities and members of the royal family are fair game.

for the queen and other senior royals, there will be great relief. the prospect of a full trial on the privacy issue in which meghan markle and herfather, thomas markle, would have been pitted against each other as the star witnesses has been averted. nicholas witchell, bbc news. the americanjazz composer and electric keyboard player chick corea has died. he was 79 years old. the 23—time grammy award winner composed jazz standards including spain, 500 miles high and la fiesta. in a statement left before his passing of a rare form of cancer, he wrote that he wanted "to thank all of those along myjourney who have helped keep the music fires burning bright." that was chick corea there, who has died at the age of 79. that's it for now, plenty coming up shortly. in

the meantime, you can get in touch with me on twitter. i'm @lukwesaburak. see you in a moment. hello there. after another very cold night, although not quite as cold as wednesday night, it's going to start frosty again through this morning with some ice to watch out for on untreated surfaces. plenty of sunshine through today, but there will be some snow showers, these continuing to affect the northeast of scotland and the northeast of england. a bit more cloud as well in towards the northern isles. and cloud further west will tend to break away as this drier air moves in from the southeast, so many places should see the sunshine. now, another very cold day when you factor in the wind, which will be a feature throughout friday. it's going to feel much colder than these temperatures suggest, subzero for all areas. now, as we head through friday night, skies will be clear,

so those temperatures will fall away again. we'll continue to see some snow showers grazing past eastern scotland and northeast england. the cloud and its snow showers and strong winds push on into the northern isles, and then over to the west, a band of sleet and snow will start to make inroads into northern ireland, the very far southwest of england. so, here, less cold than it will be elsewhere. another widespread hard frost for many of us. now, as we move through the weekend, you'll notice the orange colours, the milder air will start to very slowly creep its way eastwards. and by sunday, many areas will be less cold, certainly away from the east and southeast. so through saturday, it's a cold, frosty start, plenty of sunshine. but further west, this band of sleet and snow will very slowly make progress. but still some uncertainty on how far east it will get. but we've got early yellow warnings in force for parts of wales, northern ireland, western scotland, northwest england for some snowfall accumulations there. it'll be quite wintry, in fact, with the risk of ice too. further east, we'll have the sunshine, but it's going to be a very cold day. when you factor in the strong southeasterly wind, it's going to feel bitterly cold. in fact, it may feel as low as —10 celsius when you factor in the wind.

now, as we move out of saturday into sunday, you can see plenty of isobars on the charts coming in from the south, almost reaching gale force across northern and western areas. and the weather fronts as well will start to make better progress eastwards, so we should see more in the way of rain. and it will be of rain because milder air will be pushing in by this point, although the very far southeast may stay bright and quite chilly on the east coast. it's further west where we'll see that milder air, 8 or 9 degrees. and it turns milder still into next week, double figure values for many. could be quite wet, though, for the first half of the week, and then signs of it turning a little bit drierfor the second half of the week.

this is bbc world news. the headlines... democrats have concluded their case against donald trump in the former president's second impeachment trial. video has been shown of rioters believing they were acting under clear instructions from mr trump. his lawyers will open their case for the defence on friday. the duchess of sussex, meghan markle, has won her high court privacy claim against british newspaper the mail on sunday after it published a letter to her father. china has banned bbc world news from broadcasting inside the country for what beijing claims to be unfair and untruthfuljournalism. the british government said beijing's latest decision would only damage its reputation in the eyes of the world. one of the microsoft corporation's top executives, its president, brad smith, has expressed support for a landmark proposal by the australian government calling for the biggest online platforms to pay publishers for news.
