good afternoon. novak djokovic has been detained in australia ahead of a court hearing that will determine whether he can stay in the country. the world no 1 tennis player faces deportation after his visa was cancelled for a second time. the australian government has labelled the 34—year—old a threat to public health because he's unvaccinated against coronavirus but his lawyers are appealing, describing the decison as irrational. shaimaa khalil has the latest. free the refugee! once again, know that djokovic— free the refugee! once again, know that djokovic is _ free the refugee! once again, know that djokovic is in _ free the refugee! once again, know that djokovic is in detention, - free the refugee! once again, know that djokovic is in detention, and i that djokovic is in detention, and once again, the world number one is challenging the cancellation of his

visa. in court documents which were released today, we learned that the immigration minister made his decision because the player's presence in australia may foster anti—vaccination sentiment. the tennis star's legal team says the argument was invalid and irrational, and that deporting him would potentially undermine support for the vaccination programme. and while some of djokovic�*s supporters gathered to back him, there has been little sympathy for the tennis player. i little sympathy for the tennis -la er. ., ., ., little sympathy for the tennis -la er. ., . ., ., ~ little sympathy for the tennis -la er. ., ., ., .,~ ., player. i do feel that to make a statement _ player. i do feel that to make a statement that _ player. i do feel that to make a statement that we _ player. i do feel that to make a statement that we are - player. i do feel that to make a statement that we are sticking | player. i do feel that to make a l statement that we are sticking by what we have been calling for the last two years, i feel it is best for djokovic to probably sit one out. i for d'okovic to probably sit one out. ., , ., ., ., out. i hope that the government and the 'ud . es out. i hope that the government and the judges hold _ out. i hope that the government and the judges hold their _ out. i hope that the government and the judges hold their ground - out. i hope that the government and the judges hold their ground and - the judges hold their ground and say, the judges hold their ground and say. you — the judges hold their ground and say, you don't want to get a vaccination and you don't want to follow _ vaccination and you don't want to follow our— vaccination and you don't want to follow our rules, then you can't come _ follow our rules, then you can't come in — follow our rules, then you can't come in. ., . ~' follow our rules, then you can't come in-— follow our rules, then you can't comein. ., come in. novak d'okovic's visa was revoked the — come in. novak d'okovic's visa was revoked the first — come in. novak djokovic's visa was revoked the first time _ come in. novak djokovic's visa was revoked the first time and - come in. novak djokovic's visa was revoked the first time and he - come in. novak djokovic's visa was revoked the first time and he was l revoked the first time and he was

aside", senior tory and former minister tobias ellwood has told the bbc. meanwhile labour leader sir keir starmer said it was now in the "national interest" for the prime minister to resign — following events in downing street during strict lockdown measures. our political correspondent nick eardleyjoins me now. the latest events added to the list under investigation, is the pressure on the prime minister growing? tori; on the prime minister growing? tory mps are back — on the prime minister growing? tory mps are back in _ on the prime minister growing? to"; mp5 are back in their constituencies mps are back in their constituencies this weekend, judging the public mood, and opinion amongst politicians does seem to be hardening this weekend. they are worried, conservative mps, about the growing number of dates where we know or it is alleged that events were taking place in downing street and the country was facing those strict lockdown rules. it now spans from may 2020 up to april 2021. so as well as tobias ellwood speaking out in public, many others are worried in private. one former

cabinet minister told me that the story about the party the night before the duke of edinburgh's funeral had made things worse, that the reception they were getting was terrible. anotherformer the reception they were getting was terrible. another former ally of mr johnson and a brexit supporter said they now could not see a situation where mrjohnson led them into the next general election. that is not a view that everybody in the party shares. we should point that out. one ally of the prime minister said this morning that they think the public is willing to wait and see what comes out of the investigation thatis what comes out of the investigation that is being carried out by a senior civil servant. number 10 is keeping quiet until that report comes back. the labour leader sir keir starmer is urging tory mps to act this morning, saying getting rid of their leader would be in the national interest.— tsunami waves a metre high have hit the pacific island nation of tonga, after an underwater volcano erupted for the second time in two days. satellite images show the eruption, which was followed by darkened skies as the volcano sent black ash into the air. residents have been urged

to move to higher ground. the actor alec baldwin has handed over his mobile phone to police investigating a fatal shooting on a film set in new mexico, almost a month after a warrant was issued for the device. the cinematographer halyna hutchins was killed when mr baldwin rehearsed drawing a prop gun while filming the movie rust in october last year. wildlife experts in scotland are hopeful that progress is being made with efforts to save the native red squirrel from extinction. the introduction of the grey squirrel caused them to disappear from great swathes of the uk. alexandra mackenzie reports. the native red squirrel — not a common sight in the uk, but now limited to areas like here in barhill wood in dumfries and galloway. how many red squirrels would you have in this wood?

in november last year, we had over 30 — which is an exceptional amount. you know, there's not many places in scotland where you'd find that level. so what makes this the ideal habitat for the red squirrel? principally it's the age of the trees, that they are now producing cones regularly — and that enables food to be available at different times of the year. the larch produces cones in the summertime, the scots pine in the winter. so it gives the squirrels a good, wide feeding pattern. but of course, they're in competition with the grey squirrels. wherever you get the grey squirrels, the reds are going to disappear, unfortunately. for some, the red squirrel project is vital. well, they're beautiful creatures and they're native to the uk so i do believe that, since the grey squirrels are introduced and have wiped them out, or almost wiped them out, it's important to make sure that we can keep our heritage. it's a really nice effort from the local community. the scottish wildlife trust said

having a variety of trees benefits the red squirrel, and a predator, the pine marten, helps to control the grey squirrel population. but that is not enough. grey squirrel control is going to be necessary for a long time yet. so that will be the key thing that needs to keep continuing, in a targeted landscape—scale approach. which is tricky and hard work, but it's what is needed if we want to keep our red squirrels. the battle for survival with the more feisty grey squirrel is likely to continue for some time. alexandra mackenzie, bbc news, kirkcudbright. with all the sport now, here's chetan pathak at the bbc sport centre. good afternoon. england's batting crumbled again — before australia lost late wickets on an eventful second day of the fifth ashes test in hobart. the hosts closed on 37—3

in their second innings, a lead of 152 runs, leaving england with it all to do if they're to avoid a 4—0 series defeat. our sports correspondent joe wilson reports. this was rory burns' second chance in the ashes, recalled to england's team. this was him responding to his partner's call and racing towards the far end. here comes the replay that confirmed he didn't make it. run out. burns returned, out for a duck. his opening partner, zak crawley, was back with him shortly, caught after the ball struck his bat and pad, like that. replying to australia's 303, england needed joe root to make runs, of course. absolutely delightful. but while dawid maian — absolutely delightful. but while dawid malan was _ absolutely delightful. but while dawid malan was supporting . absolutely delightful. but while l dawid malan was supporting him, absolutely delightful. but while - dawid malan was supporting him, any hero needs friends. just when he seemed settled, dawid malan hit this to the wicketkeeper and australia's captain accepted another gift, and then he bowled again, joe root out

lbw 444, pat cummins sensed the decisive moment, and so did joe root. they both then watched nathan lyon hold this catch to dismiss ben stokes. ollie pope, back in the england team. back in his routine. edged and gone! sam england team. back in his routine. edged and gone!— edged and gone! sam billings and chris weakes _ edged and gone! sam billings and chris woakes defied _ edged and gone! sam billings and chris woakes defied together - edged and gone! sam billings and chris woakes defied together for. edged and gone! sam billings and| chris woakes defied together for a while but when mark wood's fund stops, 188 all out. so much, so little for england's batting. now they bowled again. ollie pope's flying catch, david warner, another duck. next day tumbling sam billings to get rid of marnus labuschagne, usman khawaja's glove could not evade mark wood's rocket. australia post three down from a 152 ahead. england can dream. —— australia closed three down. joe wilson, bbc news. andy murray's hopes for a first atp title in over two years are over — after he was beaten in the final of the sydney classic by the russian

top seed aslan karatsev. murray was broken in the opening game and struggled on first serve — outpowered by his opponent, but now 34, he battled harder towards the end of the second set, creating five break opportunities. but murray ultimately couldn't take them as karatsev kept his grip on the title, winning 6—3 6—3. murray will now head to melbourne for the australian open and says he's pleased to be playing at a high level again. to all of you who came out to support tonight, what an amazing atmosphere to play in and thank you. it was so good. atmosphere to play in and thank you. it was so good-— it was so good. cheering and applause i have really missed playing in front of the sorts of crowds and in these sorts of matches and unfortunately, the result did not go my way tonight but i will keep trying my best to come back and have more nights like this, so thank you and maybe see you next year.

the top two teams are currently in action in the premier league, manchester city have the chance to open up a 13—point lead. chelsea's title hopes have been fading of late, they need a win at the etihad but it's currently goalless, heading towards half time. you can keep up to date with that match on the bbc sport website, as well as today's early games in the championship and the women's super league. back to you. you can see more on all of today's stories on the bbc news channel. the next news on bbc one is at 5:10pm. bye for now. well, let's go back to politics. the

fallout from those parties. the future of the prime minister, borisjohnson. a number of conservative mps have told the bbc they've been inundated with emails from constituents, angry about reports that downing street staff held parties during lockdowns. claire pearsall is a conservative councillor in kent, who was formerly a home office special adviser. she's been telling me whether she thinks the prime minister should stay or go. i've had a number of conversations this week. the general mood is that people are incredibly angry. they have abided by the rules all the way through and faced some real hardships. but they did it because they were told to, it was the right thing to do, and to protect their family and friends and people in my village. and to see the prime minister's team and the prime minister himself

flout those rules has hit very hard. sir keir starmer has said this morning that it is time for borisjohnson to go. he says of course there is a party advantage for labour in him going, but actually says it is now in the national interest that he does. do you think that this does transcend party politics now? yes, i think it does. i know conservative supporters who are equally as angry as those who support the green party or the liberal democrats, for example. so i think this does transcend those kinds of barriers. and colleagues are going to have to work out what it is they want from the prime minister going forward, and that has to happen quickly. what do you think should happen? i think there is more to come out and i think it is not going to be very long before we see yet another revelation, so the prime minister now needs to think very long and hard as to whether he is doing the rightjob for the country, and certainly for the party. do you think he should go? i think it is probably

time for him to move on. i think that a number of colleagues now are looking at that as an option. we have seen some very senior tories come out this morning and sayjust that, and i agree with them. you have been a former adviser, you know that world well. how much will there be... how much will the various conversations be very straight forward in terms of looking ahead and saying, "well, if you don't do this or you do do that, this is where it's going to end up." because it feels like currently there is a sense of buying time and living by the day. you're a local councillor, you're not up for election in may, you're up for election next year, but there are some councillors facing pretty imminent elections. that's right. i think members of parliament will force the prime minister to look long and hard. you've got to understand there are two camps, there are the internal criticisms that aren't happening

inside number ten. he has a team around him who seem to agree with him. so that is the problem. members of parliament in westminster themselves are pretty outspoken and a pretty brutal party, to be honest. we've done it before when leaders have outlived their usefulness. those are going to be really tricky conversations, and those mps are going to be looking at what losses they are going to have come the may elections. and you say it's a pretty brutal party. the party has forced people out previously. it's not that straightforward a system. there have to be a number of mps who write letters. can you see that happening? it is quite a complicated system, and you need to look at the timing quite carefully to ensure that you have the numbers. everybody knows the magic number of 54 for the letters submitted to sir graham brady, and quite obviously we haven't reached that boundary yet. but other than that,

if you do pass that boundary, you then have to go for a vote of no confidence in the chamber of the house of commons. so you have to have the numbers to back that up, because it should the prime minister when that vote he is then safe for another 12 months. if you could talk to the prime minister now, what would you be advising? would you say wait and see if the letters come in before looking at how you handle this and shaping your destiny? and maybe taking the decision himself? yes, iwould be telling him that he needs to do this very, very quickly. he needs to assess his position, he needs to start by looking at the people surrounding him in number ten and perhaps changing up that team. that would go a long way to help. but i do agree with some of the colleagues who have already said that this feels terminal, because it really does now. if people in the team go

and he stays, how would that look? where does the culture come from? what is your experience, your understanding of the culture and who drives it? well, the culture is fed down from the top. removing a team are part of a team is only a little bit of the solution. realistically, the buck stops with the person at the top, who is the prime minister. if he has presided over this attitude that the rules didn't apply to them, which is exactly how it looks to everybody, then he needs to accept that and he is the one who needs to go. so, what would your predictions be? the coming week is going to be vital. you've said you're there, you're a local councillor, a local politician, but you are having conversations, politicians across the piece are going to be in their constituencies this weekend having conversations. i think what you will see is the report coming out at some point next week, which will list, i should imagine, the events that have taken place and who knew about it. but really, colleagues are now

going to have to step up and decide what it is they want to do. they're in that position. i'm not. i don't have any power over that. but i would hope that they are going to come together and make the right decision. lawyers for virginia giuffre, who's accused the duke of york of sexual abuse, are calling for two people — based in the uk — to give evidence in her civil case, including his former aide. prince andrew denies all the allegations. our washington correspondent, nomia iqbal, reports. virginia giuffre's legal team here in america is seeking testimony from two people in the uk. one of those people is shukri walker, a woman who claims to have seen prince andrew at a nightclub in london in 2001 with a young girl. miss giuffre contends she was then abused by the prince after visiting that club. the second person is the prince's former assistant, major rob olney. and ms giuffre's lawyers say she has reason to believe that major olney has information that relates to the relationship between prince andrew

and jeffrey epstein, the convicted sex offender who's now dead. virginia giuffre's legal team are clearly preparing for a court hearing, though they haven't ruled out a settlement, which means that it wouldn't go to trial. but they've also indicated that they wouldn't just want that settlement to be financial. as far as prince andrew is concerned, he has always consistently denied all these allegations and his team have said that this legal case is a marathon, not a sprint. but he is running out of legal manoeuvres and miss giuffre's legal team have him exactly where they want him. he's now in a position where he has said he will defend his name and he will be defending it as a private citizen, after losing his military titles and his royal patronagees, as well as his title, hrh. the pressure is increasing on him.

ukraine has accused russia of being behind a large scale cyber—attack, that hit numerous government websites. the nato secretary general, jens stoltenberg, has condemned the cyber attack. he said the alliance's experts had been in touch with their ukrainian counterparts on the issue. russia has also arrested members of the revil hacker group. revil were responsible for last year's hack which disabled the us colonial pipeline. moscow said it was cracking down on the hackers at the request of the us. john hultquist is vice president of the cyber security firm mandiant and says the hack is not as sophisticated as it might first appear. i think it's easy to overestimate this actual incident, right? you see it, this is an incident where a lot of different organisations were affected. the mod, the mfa, several other government organisations, their websites were defaced with these messages.

but the important thing to remember is you can actually oftentimes access those websites through a single point of failure. and that's probably what happened here. one system was accessed, and that allowed the attacker to essentially affect many systems at once. so these defacements are really superficial, and it didn't mean that the networks beneath these organisations were actually affected. even though it's not necessarily highly advanced, there does seem to be these little interesting details to the incident. for one, the attackers are sort of claiming to be polish nationalists. they made reference to, like, historic disputes between poland and ukraine, rather than disputes between ukraine and russia. there was also an interesting artefact in the picture files they used. there's a gps co—ordinate associated with poland. even though this was not a photograph, which is where you generally see gps co—ordinates.

so, there's... we have reason to believe that these things were planted on there, that somebody is trying to suggest that these are polish nationalists, and we know that is a tactic that russia uses often. in fact, when they had targeted the olympics and olympic organisations, they pretended to be polish nationalists, and that was the russian military intelligence agency doing that. lord sainsbury, who ran the supermarket chain bearing his name in the 1970s and �*80s, has died. he was 94. during his 40—year career with the firm, he covered several roles, becoming a director in 1958 before being promoted to lead the business in 1969. lord sainsbury retired from the company in 1992, becoming its life president. staff and volunteers at her majesty's coastguard are celebrating 200 years of saving lives. formally established on the 15th of january 1822, its role has expanded to life—saving in the uk, co—ordinating rescues on international waters and providing support in national emergencies. luxmy gopal reports.

search and rescue. for 200 years, the coastguard has been searching, rescuing and saving lives. it's such a feeling to be able to help people who've really been at a really low point, and just make that situation at the time a little bit better for them to bear, and then long—term it means someone goes home who maybe wouldn't have done. originally set up to combat smuggling, her majesty's coastguard was formally established on the 15th of january, 1822. newsreel: there's a certain amount i of mystery about the coastguard - l who he is and what he does. it's worked to keep people safe at the coast and at sea ever since. this is coastguard control. as illustrated in this video from 1972. ahoy there, coastguard here! we'll be down with you in a few minutes. hang on! when we started, it was horseback patrols looking for smugglers and people like that. that's where the "coast"

and the "guard" bit comes from. it's changed hugely. we still rely massively on our volunteers, as we have done for almost the entirety of the 200—year history of the organisation. the coastguard now has 3,500 volunteers across 310 rescue teams, in addition to ten helicopter bases. the way the coastguard saves lives at sea has changed almost beyond recognition since its creation 200 years ago, with a new updated radio network and with new technology such as drones and unmanned vehicles playing a growing part in its search and rescue operations. you've got to embrace new technology, you've got to look to improve. you can't sit still and think, "we're doing the best we can." there's always improvements to be made, so we have to look at technology. so we're looking at fibre communications, improving ourfleet to bring in electric vehicles, drone technology and how that can assist in searches, and speed up finding people that are in difficulty.

so, really, we'vejust got to be open to change and embrace it and look to improve at any point we can. to mark the organisation's milestone birthday, 200 throw lines are being cast into the seas around the four nations today, as a symbol of the coastguard's life—saving role, past and present, on our shores and at sea. luxmy gopal, bbc news. if you've ever played a contact sport, you'll know how important a good mouthguard can be at now they're being used to help safeguard another part of players�* bodies — their brains. they're notjust any old mouthguards, though. these ones — which are being tested by leeds rhinos rugby league players — are fitted with technology to measure the impact of tackles which may cause concussion. tanya arnold has more. rugby league is a collision sport. you can't change that. but these new mouthguards will gather data on what each player is experiencing.

so, a normal gum shield will obviously be to protect the teeth. and these are... these have embedded technologies, so, batteries and gyroscopes and because the teeth and the upperjaw is fixed to the skull, we can then look at how fast and how forceful the heads moving on impact. leeds beckett is leading the study, testing out several different makes to determine which they feel performs the best. we're looking at how these mouthguards perform in a laboratory, so when we hit them with a pendulum, how they perform on the field, when a player gets tackled or doesn't get tackled. so, we're looking at the force, positive force or negative, so the accuracy of them. and then it's also really important to understand the players�* fit, comfort and function, because they have to wear them. they have to embrace the new technology. this is leeds rhinos academy player mackenzie turner being tackled while wearing one of the mouthguards. and this is the data from it. on our graph here, we can see the linear acceleration, which is measured as g—force. and that corresponds

to the y axis, which is this direction, through your head. so, it's a negative peak, so, we know that the... the linear acceleration is to the left, so we know that he must have been hit to the right of his head. the collision was measured at a force of around 25g. they haven't yet put a figure on when concussion occurs. sort of anywhere sort of north of 706 is usually that's when we start to get a bit worried that there might be a concussion there. but, at the minute, we don't really know exactly where that figure is, that value is. it'sjust about, yeah, monitoring it and trying to get an understanding for what players are going through. concussion in sport and its long—term effects have become a big issue but mackenzie admits it's not something he's currently thinking about. i think, long term, yeah, . probably it's good to know. but, you know, when i'm playing and stuff, - i don't really think about that. i just think about playing and doing myjob. - it's a view echoed by england

and leeds full—back caitlin beevers, who's been playing the game since she was six, but she's fascinated by how the information gathered can transform the game. i'm interested in anything factual, scientific, and the fact that we can look at our data and it can actually be brought back to training and how we can save us from hitting those type of impacts. rugby league hopes to roll out the preferred mouthguard to all levels of the game later this year. it's early days in the study, but as more data is collected, so the understanding of what each player's brain is being put through in both matches and training will grow. tanya arnold, bbc news, leeds. now it's time for a look at the weather, lets join matt taylor. we got a bit of sunshine around at the moment. for many of you, misty and foggy. this is the view a short while ago in york. the area of high

pressure that was with us has slipped southwards, and that is allowed more cloud and moisture to push in. hence there is conditions across the country. very few brakes on our satellite imagery. a bit of drizzle out towards the west. we are going to see some sunnier breaks towards the south—west. here are some showers develop. some of the best of the breaks across the north—east of scotland. temperatures are struggling today. 2—3 in parts of yorkshire and lincolnshire. around 10—11 around the south—west. the wind picks up in the north of the country. a band of rain for much of scotland and northern ireland tonight, pushing into the borders of england by the time we had six o'clock tomorrow morning. with that and showers in the south, more breeze, more cloud, more blue on the chart. not as frosty tomorrow morning. that weather front pushes its way southwards, starts its day around the borders of northern england. will work its way

southwards. it does mean scotland and northern ireland, a brighter day for you tomorrow. a few showers in the north. a cloudier, wetter spell for south wales. that cloud increases towards the south for some showers. winds are still reasonably light. that breeze is coming off the atlantic, so temperatures up from what we have seen over recent days. 7-11 . what we have seen over recent days. 7—11 . sky start to clear into the evening, temperatures will drop. they colder night once again. high pressure builds back in across the country. around the centre of it, where the winds will be light, greater chance of fog. most of you, though, will have a dry and sunny day on monday. light winds as well. feeling quite pleasant out there after a frosty start. a bit more cloud in the north and west. that breeze will increase further as we go through next week. a stunning start, but some wet and windy times.
