a dispute over covid rules. australia's immigration minister, says the latest visa cancellation, was made on the grounds of "health and good order." djokovic�*s lawyers say he will appeal. the men's tennis number one is still scheduled to play in the australian open in melbourne on monday. our correspondent, shaimaa khalil, has the latest, from melbourne. this has the latest, from melbourne. is the scene live c lawyers office this is the scene live outside his lawyers office on saturday morning. this is nine news, live from sydney. just moments ago, the immigration minister has cancelled novak djokovic's visa. it's a story that made headlines here in australia and around the world. for days, novak djokovic has been on the courts training, and now the government has finally announced its decision. the tennis star's visa has been cancelled again, and for the second time, he faces deportation from australia. in his statement, the country's immigration minister alex hawke said. today i exercise my power to cancel the visa held by mr novak djokovic on health and good order grounds, on the basis that it was in the public interest to do so. the prime minister scott morrison said the sacrifices australians made throughout the pandemic should be protected. mr morrison's government has faced heavy criticism for allowing the unvaccinated player into australia in the first place while the country struggled with a spike in covid—i9 case numbers. they made a pretty mess of it, they did, but now i think they corrected it. it is unfortunate if novak won't be playing in the tournament. it's a pretty big loss. yeah, i think if everybody else has to follow the rules, why can't he? and obviously, he thought he was above it all. the australian open is only a couple of days away, and there are now huge doubts over whether novak djokovic will be able to compete. but even if he did secure his freedom, a chaotic and stalled preparation will only get worse with him spending the weekend andy murray says the controversy has been bad for the sport. itjust seems like it has dragged on for quite a long time now. yeah, not great for tennis, not great for the australian open, not great for novak djokovic. his former coach, the multiple grand slam winner boris becker, said this story has become about more than just sport. he is only a tennis player. we are alljust sportsmen, we are not politicians. if we are used in a political way, then we don't have a chance. the world number one is still fighting to defend his title here. whether or not he will be able to play, the australian open will take place under the shadow of a controversy that has gone way beyond tennis. earlier, i spoke to the barrister greg barns, who's experienced in visa cases. he said, australia's immigration minister, has the power to cancel mr djokovic�*s visa, without having to give written notice or a reasonable time for him to respond. this decision is being made with many a grecian field godlike powers. in other words, the minister has the capacity to cancel a visa on vague grounds if you see the public interest, good order, health public risk, public health. in this particular case and many of these cases there seems to be a political overturn. you can get away with it because of the broadness of the description that's being used by the government. the broadness of the discretion used in the political overin discretion used in the political over in this particular case makes it inevitable to take it into political consideration not matter how they dress it up to be matters of public policy. it how they dress it up to be matters of public policy-— of public policy. it sounds as if what you're — of public policy. it sounds as if what you're talking _ of public policy. it sounds as if what you're talking about - of public policy. it sounds as if what you're talking about here of public policy. it sounds as if i what you're talking about here is not particularly mr novak chuck affixes case but more wider views or issues. —— djokovic. in his case as he met conditions to have a visa issued to him to enter the country as the law stands right now? well. as the law stands right now? well, because it's _ as the law stands right now? well, because it's a _ as the law stands right now? well, because it's a matter— as the law stands right now? well, because it's a matter of _ as the law stands right now? -ii because it's a matter of discretion, evenif because it's a matter of discretion, even if you make mistakes in the way in which you apply for the visa, for example, in relation to the question of whether or not he had covid in those matters, they aren't relevant. but because of the broadness, even if you've made errors or some of the factors that have taken into account had not been met, the minister can still refuse to cancel your visa or two certainly the court set on monday that what we know is what more can this man do? that issue of whether or not mr djokovic for example a is a risk to public health, that's something they will entertain in a court over the next 24 entertain in a court over the next 2a hours as to whether or not it was reasonable to say mr djokovic in his particular case represented a risk to public health. downing street has apologised to buckingham palace, after it emerged 2 parties were held at no.10, the night before the duke of edinburgh's funeral, last april. a spokesman for borisjohnson, said it was �*deeply regrettable, that the events took place at a time of national mourning'. covid rules had meant indoor mixing was banned, but reports suggest there was drinking and dancing at the parties, into the early hours. the prime minister didn't attend either party — but the latest disclosures have amplified calls for him to resign. with the very latest, here's our political correspondent, ben wright. it was a moment of national mourning, flags flying at half—mast in honour of prince philip, the duke of edinburgh. but inside number ten, on the evening of the 16th of april last year, two parties took place. there was drink and music at a time covid restrictions on indoor mixing in england were in place. ..restrictions the queen followed at the funeral of her husband the following day. when i heard about this, i was, of course, very, very concerned. and i understand that people across the country are angry about what has happened. earlier this week, the prime minister did apologise for mistakes that have been made. according to the daily telegraph, downing street staff were sent to a nearby shop with a suitcase to buy more booze. number ten has not denied any of this. boris johnson himself was not there. itjoins the list of events being investigated by sue gray, a senior civil servant. as well as the two parties on the same night in april last year, back in december 2020, we know of several gatherings — both in downing street and government departments — including one on the 18th of december, about which the prime minister said this. i have been repeatedly assured since these allegations emerged that there was no party and that no covid rules were broken. the list goes on, with events in november 2020 being looked at. there was a gathering in the number ten garden on 15 may 2020 and a bring—your—own—bottle event on the 20th, which borisjohnson has apologised for attending. today's chastened apology to the queen is the latest twist in a saga that has engulfed number ten. as new revelations have dripped out, downing street has appealed for patience, saying all the facts will be known when sue gray publishes her report. but many tory mps are livid about the prime minister's handling of all of this and the apparent culture inside number ten. a handful of conservatives have written letters to the parliamentary party, asking for a confidence vote in boris johnson. we've delivered brexit, he's got us through the pandemic, but now his leadership's in question. he needs to step aside. sutton coldfield is a true blue seat in the west midlands. but last night, its conservative association voted unanimously to withdraw its support from mr johnson. the constituency�*s mp is a former cabinet minister. are you asking for his resignation? i'm not. i'm not normally a letter writer, but i'm waiting to see what sue grey reports. it is of immense concern, and i'm very conscious that in the local community, in royal sutton coldfield, people are aghast at what's been going on. here and across the country, tory mps will be sounding out their local parties and voters. i think it's disgusting. they're like a rudderless ship, really. i think it's a vendetta - that the media have got. opposition parties are now calling on the prime minister to quit. the prime minister allowed this to happen in number 10, not once, not twice, but on multiple occasions. the culture was, it's one rule for everybody else and one rule for us. for a prime minister under intense pressure, much hangs on an inquiry that could lay bare whether those responsible for setting lockdown rules repeatedly broke them. in the uk, official figures show covid infections climbed to a record high in the first week ofjanuary, with an estimated a5 million cases. london was the only part of the country to see a fall in infections during that period. health officials are concerned about the slower take up of booster vaccines in some areas. here's our health editor, hugh pym. there is a new push to get people boosted, including here in nottingham and across the east midlands. take—up of boosters nationally has been much slower since the new year. and in some communities, it's only a third of the average, with the message not always getting across. a part of me questions whether it's actually effective. and how many are we going to have to have after that? i really want to get it done, because of everything you see in the news, really. health officials in the region say the booster roll—out may have slowed, but they're still busy. we are still continuing to see hundreds of people coming in each week for their first dose, so we have to recognise that people are on a slightly differentjourney. at this gp practice in kent, though, the waiting area for vaccinations, including boosters, is sometimes empty. our clinics really have been a lot less busy. we've also had problems where patients aren't turning up when they've been invited. he says getting the under—30s to come forward for boosters hasn't always been easy. that age group were vaccinated later, so their booster's come later. quite a lot of them have had covid, and you can't vaccinate someone within four weeks of having covid, but we still think there's quite a lot of young people out there that are eligible that we are very keen to boost. senior health officials say there is now high confidence that omicron causes low severity of disease in adults, but the variant is still spreading. the latest survey by the office for national statistics suggests that a5 million people in the uk had the virus last week, up 15% on the previous week, though that rate of increase was lower than during the week before. in england, it was one in 15 who had the virus. in scotland, wales and northern ireland, one in 20 people. medical experts say more babies are going to hospital during this latest covid wave, but they're not very sick with the virus — which they say is reassuring — and covid poses a very low risk to children. hugh pym, bbc news. washington and kyiv have accused russia of preparing to carry out �*false sabotage operations' — to create a �*pretext�* for an invasion of ukraine. the pentagon said, moscow had sent a group of trained operatives into eastern ukraine, who could carry out acts of sabotage, against russia's own proxy forces there. ukraine's defence ministry said, russia was plotting to stage similar operations in neighbouring moldova. the kremlin has denied the reports. but speaking at a news conference, the pentagon press secretary — john kirby — said us intelligence indicated that the plans were well underway. we do have information that indicates that russia is already working actively to create a pretext for a potential invasion, a move on ukraine. in fact, for a potential invasion, a move on ukraine. infact, we for

senior russian officials. almost on a weekly or biweekly basis as i gather. but i suspect and here is there was enough information provided to the fsb, the russian domestic security service and they took action upon that request. what i find curious is took action upon that request. what ifind curious is the took action upon that request. what i find curious is the timing took action upon that request. what ifind curious is the timing of took action upon that request. what i find curious is the timing of it. yeah. talking about timing, how independent are revil? because many people said it's actually the russian government that are behind a lot of these hacking organisations. well, i don't know if that's necessarily the case. there's not a whole lot of evidence to suggest that the intelligence services themselves are conducting operations or even directing operations. but i think it's important to note that given the length of time that these criminal activities has taken place out of russia, the security services are certainly aware of it. and what today demonstrates, this take—down demonstrates that the russian security services have the ability to control these activities and these actors. in fact, they may even be exerting influence through this operation and consolidating control. very quickly, we hear of the cyber attack on ukraine from russia. it’s attack on ukraine from russia. it's not clear attack on ukraine from russia. it�*s not clear exactly who has done this orfor not clear exactly who has done this or for what purpose. not clear exactly who has done this orfor what purpose. even not clear exactly who has done this or for what purpose. even though i'll point out that the ukrainian government has indicated some connection to russian security services. but this is the sort of low—level activity that i would expect in times of increased geopolitical conflict. it's quite easy to do. but again, it's not clear exactly who did it but all signs point to some sort of russian based actor, at least for now. thank you. a 32 year old british army officer, who says she's challenging the stereotype of polar explorers, has returned to her home in

beautiful winter's day across much of the uk. we started off with frost and fog, which lingered all day for one or two places, followed by a lot of blue sky around. but under those clearer skies through tonight, frost and fog once again going to be a bit of a hazard for some of us. it's a little bit milder across the far northwest of the uk, but high pressure in charge further south, and that's going to drive this settled theme to the weather with us at the moment. breezier conditions with a bit more cloud across northern parts of scotland, northern ireland too, as we head through this evening and overnight. so not quite as cold here, a little bit breezier and notjust extensive fog, as we'll see further south, particularly through lincolnshire, east anglia, the midlands, into eastern wales — the welsh marches, for instance, seeing some fairly extensive fog which could linger through tomorrow morning. temperatures first thing tomorrow getting a few degrees below freezing in a few spots in our towns and cities, so a chilly start to saturday, some frost around under the clearer skies and also that fog which could be quite slow to clear from lincolnshire, into the midlands, for instance, as well. a little bit cloudier across the rest of england and wales compared to today, but still there will be some breaks in that cloud and some glimpses of sunshine for many areas. a little bit brighter for northern ireland and eastern scotland as well. temperatures close to the east coast are going to struggle at around five degrees, but up to 11 there in the southwest. staying close to freezing, though, if you are stuck underneath one of those pockets of freezing fog for much of the day. now, heading into sunday, and a weak weather front moves in from the north. it's a cold front, but it's not bringing particularly cold air. in fact, we've got milder conditions with the breeze and perhaps just one or two showers across the far northwest of scotland. a few splashes of rain on this weather front, but easing away as it heads south across england and wales. the sunshine returning from the north and temperatures probably a touch warmer than recent days, around seven to 11 degrees on sunday. looking ahead into the new working week, after the weekend, that cold front gets out of the way, fizzles away, and that high pressure very much with us once again as we look ahead into monday. so monday morning could bring some frost and some fog once again, fog particularly for parts of the southwest of england, into wales too. elsewhere, light winds, a lot of dry and sunny wintry weather for you on monday. not a bad day at all, but some of us could do with a bit of rain and it's going to be staying dry. temperatures around about seven to perhaps 12 celsius or so. could see a little bit of rain in the north and the west, i think, on tuesday, but much of the week ahead looking dry and settled. sunshine by the day, but frost and fog by the night. bye— bye. this
