step aside". tobias ellwood made the comments to the bbc as pressure continues regarding parties at downing street while tough coronavirus restrictions were in place in the uk. meanwhile the labour leader sir keir starmer said it was now in the "national interest" for the prime minister to resign. the moral authority matters in relation to enforcing the covid rules but we've got other massive challenges facing this country. massive challenges. we have a prime minister who is absent, he is literally in hiding at the moment, and unable to lead. and so that is why i have concluded that he has got to go. and of course there's a party advantage in him going, but actually it is now in the national interest that he goes. so it is very important now that the tory party does what it needs to do and gets rid of him. claire pearsall is a conservative councillor in the county of kent, who was formerly a home office special adviser. she spoke earlier to my colleaguejoanna gosling, who asked whether she'd had a chance to speak to local residents in her area. 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. earlier i spoke to our political correspondent nick eardley. this weekend is quite an important gauge of that for tory mps. they are back in their constituencies, trying to judge the public mood, and from the ones i've been speaking to, it doesn't seem great, quite frankly. a former cabinet minister was saying the story yesterday about the party the night before the duke of edinburgh's funeral made things worse, they thought the reception they were getting was terrible. it is interesting, anotherformer ally of the prime minister, a brexiteer, said they didn't think there was any way the pm could now lead them to the next election. and there is a growing list of things that are being looked at by the senior civil servant sue gray. i suppose the question is whether the mood amongst tory mps starts to harden, whether they feel under more pressure to act, and the labour leader sir kier starmer urging them to do so this morning, saying it would be in the national interest. we are not getting much from number ten. they are saying wait for the investigation to come back. but they must be feeling the heat this morning. this afternoon, rather. yes, how time moves on. what do the next few days look like? i think the start of next week will be important to see exactly how tory mps feel, if they have decided they need to act against the prime minister or not. i should point out there are some allies of borisjohnson saying they think the public is prepared to wait for the investigation to come back before making their minds up. we may get that investigation next week, we don't know for sure, but there have been ministers suggesting it would be soon. and that will be a big moment, because if the senior civil servant looking at this, sue gray, says the prime minister did something wrong, or there was a problem in number ten, or there were other events or that the prime minister was at them, i think it adds more pressure to him. is it guaranteed that borisjohnson goes? absolutely not, because he still has his supporters, those who think he is an electoral asset, there are still a number of measures that would need to be taken, a number of steps gone through for him to be removed from office by the conservative party, but he is under a lot of pressure, more than he has ever been under as prime minister. this inquiry by sue gray, which the government keeps referring to and asking everyone to be patient until those findings are published, that is getting bigger and bigger as more events come to light, it's not her role to be judge and jury on this — it's a fact—finding inquiry. you are totally right. nobody expects her to come back and say that a crime was committed, it's not her remit to judge whether borisjohnson has broken the rules that ministers have to follow, the ministerial code — it is a fact—finding mission. i suspect we'll be poring over the language of it. because if other events are brought to light, if there is a suggestion the prime minister knew about things that could be rule—breaking, or a suggestion he broke the rules himself, i think that would add to the pressure. one senior tory said to me last week if there is a suggestion the prime minister has broken the rules or done something seriously wrong, it could be terminal. chris hopkins is political research director at the market research company sava nta comres. he explains what their latest polls on uk voter intentions are showing. what it shows is for the first time in a long time a ten—point labour lead. we haven't seen a ten—point labour lead since 2019, in a very different political climate, we had the brexit party on 14% and change uk on 9% then so it goes to show how much has changed since then. also the labour vote share was 42% in this latest poll, and we haven't seen that since 2013, so a long time. ultimately what these figures show with this ten—point lead and the large labour vote share, voters are going away from the conservative party in the wake of partygate. these latest scandals have been really bad for the conservatives. if the prime minister is seen to be an electoral asset for the conservative party, it doesn't seem to be the case any more, therefore those in the 1922 committee, those conservative backbenchers that owe borisjohnson theirjob having done so well in the 2019 general election, if he takes them into the next election and they lose their seat, they will not be very happy with him. many unhappy constituents have been contacting their mps of all stripes to say they are unhappy with the way the government ministers and officials, advisers, have been behaving. how is that reflected in the voting intentions of people who have been conservative supporters in the past? what we have seen in our latest poll is thatjust two thirds of people who voted conservative in 2019 are sticking with the party, some are going to other parties and a large proportion are undecided. those who voted labour in 2019, they are retaining 87—90% of their vote. so we're seeing considerably more conservatives moving away from the party than labour. they are not all going directly to labour, some say they are undecided and those may be easier for the prime minister or possibly the next leader of the conservative party to win back, but some of them are going to other parties and they will be considerably more difficult to win back and it may take a change of leader in order to do so. what is the public saying about whether the prime minister should resign? seven in ten say he should resign, that was in our latest figures published last night. we saw two thirds, 66%, say he should resign on tuesday. what we will probably be asking over the weekend is whether he should resign again in the wake of the latest revelations. the poll we published last night didn't include the story about number ten staffers parting on the night before prince philip's funeral and i think that will increase public outrage, and although the prime minister supposedly wasn't at that event, i think what we are seeing is people think the buck should stop with the prime minsiter, the public see the prime minister is ultimately setting the number ten culture. i think if there continue to be revelations of more flagrant breaches of lockdown in number ten then the public do see that the buck should stop with the prime minister and more and more will say that he should go. let's take a look at the uk's latest covid figures. there have been 81,713 positive cases of covid 19 in the past 2a hours. 287 deaths have been recorded within 28 days of a positive covid test. and over 36,295,000 people have now received a boosterjab — that's 63.1 % of the population novak djokovic has been detained in australia ahead of a court hearing that will determine whether he can stay in the country. the world men's number one 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, novak 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 alex hawke 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 do feel that to make a 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 this one out. i hope that the government and the judges hold their ground and say, you don't want to get a vaccination and you don't want to follow our rules, then you can't come in. when novak djokovic's visa was revoked the first time he was held here at this immigration detention hotel. more than a week later, he's back. only two days before he is meant to compete in the australian open and defend his title, this is where he will be spending the night, and when he does get out on sunday, it won't be to go to practice — he will be in his lawyer's office while a court decides his fate. his rival rafael nadal said the grand slam is not just about djokovic. the australian open is much more important than any player so if he is playing, finally, ok, if he's not playing, the australian open will be a great tournament with or without him. that is my point of view. sunday's court decision is crucial for both sides — the top seed whose chance at a 21st grand slam rides on it, and a government that has been hugely embarrassed by the mishandling of the saga. shaimaa khalil, bbc news, melbourne. lawyers for the woman accusing prince andrew of sexual assault are seeking testimony from two people in the uk. meanwhile prince andrew's legal team want to question his accuser�*s husband and her psychologist as part of his civil sex case. prince andrew, seen here leaving the windsor estate with sarah ferguson, also argues that ms giuffre "may suffer from false memories". the duke has repeatedly denied claims aganist him. 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 uk foreign secretary has accused russia of waging a disinformation campaign to destabilise and justify an invasion of ukraine. liz truss wrote on social media that russia must halt its aggression, de—escalate and engage in meaningful talks. it comes after a week of us—russian talks aimed at defusing tensions. russia has amassed tens of thousands of troops on the border with ukraine, prompting invasion fears. the africa cup of nations continues in cameroon, where nigeria havejust scored a goal against sudan, following a 1—0 victory against egypt in their first match. later, egypt, who have won the cup of nations a record seven times, will have a chance to get back on track with a win against guinea—bissau. i'm joined now by the bbc�*s ian williams who is in yaounde. a last minute change of coach for nigeria ahead of this tournament, a risk that's paying off? not ideal preparation getting rid of your manager withjust not ideal preparation getting rid of your manager with just weeks before a major tournament but it seems to be working for nigeria, already 1—0 up be working for nigeria, already 1—0 up against sudan, the goaljust three minutes into the match. you can add that to their opening win against egypt. so the man who manages nigeria, he has managed them before, he is only here for this tournament before another manager takes over, but he has brought a positive approach and it went well with the fans. ex—players and pundits excited by the performance by nigeria in the opening game. you had the likes of ian actual ——... a strong british feel involved in the nigerian team. things are looking good for them. the coach, neutralised mohamed salah, another who plays in the premier league, by doing what he said, a basketball term, a double press, to keep him quiet in the game and it worked. things are looking good for nigeria, the second win in two games, if it comes to pass will take them to the knockout stages joining morocco and cameroon. sudan won in 1970 but they have only been in the cup three times. they are underdogs today. a short time ago they were 1—0 down already, with nigeria leading. you mention the _ already, with nigeria leading. you mention the pressure on mohamed salah. that will surely continue with egypt going into their next match bottom of the group. certainly man view match bottom of the group. certainly many view mohamed _ match bottom of the group. certainly many view mohamed salah _ match bottom of the group. certainly many view mohamed salah as - match bottom of the group. certainly many view mohamed salah as the . match bottom of the group. certainly i many view mohamed salah as the best player in the world currently on form, he has been almost unstoppable form, he has been almost unstoppable for liverpool but he is surrounded by the likes of sadio mane and other fantastic players who create fantastic players who create fantastic opportunities, but he doesn't necessarily have that playing for egypt. he has to carry the expectations not only of his team but the nation of egypt, seven time winners, nobody has won more times than them, they are searching for an eighth title, so there will be pressure on. other players will have to step up and try to help mohamed salah. don't count out guinea—bissau today. they did very well in their opening game, 0—0 against sudan, they should have done it, the monaco midfielder missed a penalty. large crowds of hindu worshippers have gathered on the banks of india's ganges river for a holy bath in spite of a 30—fold increase in coronavirus cases in the past one month. similar festivals are taking place across the country. doctors in west bengal applied to stop its festival this year, worrying it would become a super spreader event. india reported over 260,000 new coronavirus cases on friday. aru na iyengar reports. varanasi in the northern state of uttar pradesh. thousands of pilgrims throng the ganges river banks to take part in the magh mela festival. they believe bathing in the sacred waters will wash away their sins. translation: nobody - is following the guidelines. announcements are being made to urge people to wear masks. what can the government do? the mistake is on our part that we should be following the rules, but nobody is following the rules, nobody is ready to listen to the rules. at the gangasagar festival in west bengal, officials try to enforce covid restrictions. pilgrims have to show their vaccine certificates along with an rt—pcr test report ta ken two days before arrival. but most here believe god will save them from covid. 3 million people are expected here. doctors asked of the state high court to stop the festival, fearing it would become a super spreader event, but that was rejected. they are worried because last april there was a record rise in coronavirus cases after the government of uttarakhand state in the north allowed the massive kumbh mela festival to go ahead. the indian prime minister, narendra modi, says the festivals show india's vibrant cultural diversity. meanwhile, coronavirus cases are predicted to peak next week in new delhi and mumbai as the country battles with the highest number of cases since may last year. today marks 25 years since princess diana walked through a minefield in angola to raise awareness of the lasting impact of conflict. diana captured global attention when she walked through the live minefield in 1997, escorted by the british landmine clearance charity the halo trust. she never lived to see the full impact of her visit — such as the signing of an international treaty to outlaw the weapons — as she died later that year. we've been speaking to louise vaughan from the halo trust who explained how that walk was organised. she was already involved with the international red cross and she was planning a trip to angola to to show the terrible effect these weapons have on people including children. the minefield had recently been cleared by my colleagues. it was amazingly brave of her. it is important to realise that when she visited the civil war was still raging, things were very dangerous there. she was clearly quite nervous about walking through the minefield but she was very shrewd. she knew that those images of her would absolutely become a global front—page news everywhere and it would make it impossible to ignore that there had to be a universal ban on these indiscriminate weapons. the instant impact was tremendous. everybody is now familiar with those images, one of the most iconic of her life. within months there had been a grassroots campaign to ban landmines throughout the world for a number of years but by making it front—page news she made it impossible for governments to ignore. so the anti—landmine ban treaty, the oxford treaty, came into being by the end of the year. tragically she didn't live to see that but that treaty is still one of the most successful of all time, 164 signatories. landmines are virtually obsolete now from production and use, and we have seen over 30 countries cleared of landmines, including mozambique which was one of the most heavily land mined countries on earth. so an extremely powerful treaty and has saved literally millions of lives. 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. now it's time for a look at the weather with matt taylor. hello. while some of you saw the sunshine today, there was a lot more cloud around across the country, and that will have a consequence for tonight, in that it will not be anywhere near as cold, so not as much frost around, and certainly less in the way of fog, too, and it's all because of what's happening out to the north—west of us. an area of high pressure is clearing away, allowing these weather fronts to approach in. this one bringing some showers across the south, this one bringing some wet and windy weatherfor a time in scotland, especially. now, we go into the night with most starting dry, but those showers develop across the southern areas, and then outbreaks of rain pushing southwards across scotland, northern ireland. could see strong to gale force winds for a time in the north, and overall a breezier night here. that will keep the frost at bay for many. temperatures by and large above freezing. as you can see, very little blue on the map, but there could be the odd pocket of frost, and also fog to take us into the start of sunday. so, this is the setup for sunday. got high pressure trying to build in again from the west, but for the time being, this weakening weather front to be working its way southwards, bringing the bulk of the morning rain across northern england and north wales, after it's quickly cleared away from scotland and northern ireland, leaving a dry, sunny day for many, but blustery, with a few showers in the far north. that cloud and patchier rain pushes through wales and the midlands during the middle part of the day, and then into the far south later on, by which time very little rain on it. winds still light across many southern areas on sunday. a blustery day across the north, but the winds aren't coming off the atlantic, so, if anything, it will be a milder day on sunday compared with saturday. temperatures a degree or two above where it would normally be at this stage injanuary. but as we go into sunday night, you can see clear skies across much of the country, lighter winds the further south you are. that will lead to some fog patches, and the blue appears back on our temperature chart, an indication of more widespread frost to take us into the monday morning commute. there will be temperatures in the towns and cities just above freezing, but one below it in the countryside, and that's because we've got high pressure in place. towards the south—west of the uk, and with winds lightest here, wales, south—west england, could be some lingering fog patches through the morning. elsewhere, most places will have a dry day. lots of sunshine around on monday, cloudy as conditions in the far north of scotland, isolated shower or two. most, though, will be dry. temperatures not far off the seasonal average at this stage in the year. as for next week, well, after that sunny start to the week, there is the chance of some more cloud and some breezy conditions with outbreaks of rain in scotland, northern ireland, on tuesday and wednesday. that clears away, temperatures drop a little bit, but overall we go back to where we are now, with many places dry by day, some frost, fog forming by night. bye for now. hello, this is bbc news. the headlines: pressure for borisjohnson — as details of lockdown parties in downing street continue to emerge, some conservative mps say they're being inundated with messages from angry constituents. the leader of the opposition says it's now in the national interest for the prime ministers to go. novak djokovic spends the night in an immigration detention hotel in melbourne, ahead of a court hearing to decide whether he'll be deported
