part in this story. i've been speaking to a few of the local residents that taxi drivers who have told me that speeding is a main issue, particularly on this road. it issue, particularly on this road. it isa issue, particularly on this road. it is a busy main road behind me, the speed limit goes from 50 miles an hour to 60. speed limit goes from 50 miles an hourto 60. a speed limit goes from 50 miles an hour to 60. a few of them have told me, particularly residents, they have had a few misses. they said it was an accident waiting to happen. they are calling for action or for a change to be made so this doesn't happen again. thank you. the russian opposition leader, alexei navalny, has been detained by police in moscow. he was arrested as he attended a demonstration in moscow supporting a boycott of the presidential election in march, which he claims will be rigged. earlier, his headquarters were raided by police. this was what he had to say to his own online news channel before he was arrested. translation: i'm the head of the anti—corruption fund and i was a presidential candidate, but first and foremost, i'm a citizen, who wants to have normal election and who is not prepared to take, any longer, all this nonsense that's been going on for the past 18 years. and to extend this nonsense for another six years. well, let's take a look at the live pictures of the demonstrations in russia. this is one in moscow, in fact, in support of the opposition leader. a lot of demonstrations against the president putin regime, one in saint petersburg at the moment and this one in moscow. in the capital. in the last hour we have heard the news that the russian opposition leader, alexei navalny, the leader of these demonstrators has been arrested as he was attending a demonstration that was supporting a boycott of the presidential election in march. alexei navalny has said he believes that presidential election will be rigged. that's the latest from russia, more on that as it comes in. the cabinet office minister david lidington has urged the conservative party to "come together" amid growing rifts in the party over brexit. his comments come as the former northern ireland secretary and prominent leave campaigner, theresa villiers, has said she fears the uk is heading towards "a dilution of brexit." our political correspondent, susana mendoca, told me that ms villiers' comments add to pressure on the prime minister from some other conservative mps. they‘ re concerned about the direction of travel. theresa villiers, in this article, actually says that as far as she's concerned, that direction of travel has only been going in one single direction and that's, in her view, towards a dilution of brexit. in particular, i think we must retain the right to diverge from eu laws. one of the key points of leaving the european union is to ensure that we can, once again, make our own laws in our own parliament and not be subject to laws made by people we don't elect and we can't remove. that is something other people have also talked about. we've heard today from jacob rees—mogg, who has spoken about this time and again, a backbencher, a eurosceptic, and he says as far as he's concerned, he thinks the problem is that there is no clear direction, there's no clear time frame on when britain would cease to have to adhere to the rules of the eu. i think this is troubling, on the number of counts. first of all, the prime minister said "implementation", which meant we would have left and then we would be implementing the consequences of having leaving. but currently, there's no clear destination, either in the government's mind or indeed agreed with the european union. and there's no set limit. one friend of mine said it looked more like a plank than a bridge. number ten has said that the government is committed to delivering brexit. today, we heard from david lidington, who is a cabinet david lidington, who is a cabinet office minister and he said after brexit britain was definitely have the power to diverge from things they didn't want to adhere to in terms of the way that european structures work with trade. he talked about how there is a need, as far as he's concerned, for the party to come together. it's the conservative family — left, right and centre, because we're broad church — needs to come together in a spirit of mutual respect. you know, there are differences in any broad church. and look at what the bigger picture is showing. the bigger picture is showing that after eight years in government, we are still neck—and—neck with the labour party in the polls, we are taking seats off them in places like bolton in local government elections last week. that's what the various strands of the conservative party think and we've also been hearing about labour and from jeremy corbyn on what labour think about brexit. what was interesting, we see the divisions within the conservative party. there are potentially divisions also within the labour party. a lot of labour members want to have a clearer direction from jeremy corbyn on what happens after brexit. today, we had some of that from jeremy corbyn in particular on the issue of the customs union. he was basically saying that after brexit he would want there to be a kind of customs union, not the one that exists now. he talked about not wanting to go down the norway route and replicate that model but certainly to have some kind of customs union and maintain that close trading relationship. on the issue of free movement, while he said that there would be no free movement, he talks about easy movement, making sure that when we need nurses from the eu and what have you, they would be able to come over. a bit more detailfrom him. this is what he said. we would want a form of customs union. obviously, whether it would be the customs union, the answer is no, because it would require being a member of the eu, which we're not. we could agree to be in the customs union without being a member of the eu. we need to be sure that any agreement with the eu gives us the chance to influence the situation we're in and the trading relationships we want. now, look, i would want to see trade relations with the rest of the world going on and increasing, of course. but also, i would want to see conditions put on those trade. conditions for environmental protections, conditions for human rights, conditions of workers' ability to represent and negotiate themselves. that's jeremy corbyn. the prime minister has been criticised for the way she's negotiating brexit by some of her own conservative party, by the labour party as now by donald trump, as well! yes. it seems to a criticism. donald trump was asked about brexit and whether or not he would have taken the same route. he said he would have been tougher, the indication that theresa may perhaps has not been tough enough. there are those within the tory backbenches who feel that the prime minister needs to be tougher. perhaps not the most helpful interventions on donald trump's part. this is what he said. do you believe that we're in a good position, britain? a lot of people are still very i'iei’vous, very anxious. but hearing the president of the united states saying, "hey, there's plenty of trade coming from me", that's a big deal to people in britain. well, would it be the way i negotiate? no, i wouldn't negotiate it the way it's negotiated. but i have a lot of respect for your prime minister, and i think they are doing a job. i think i would have negotiated it differently. i would have had a different attitude. what would you have done? i think i would have said that the european union is not cracked up to what it's supposed to be. and i would have taken a tougher stand in getting out. we will hear more about what the european union thinks tomorrow, we are expecting the eu 27 to come forward with their proposal to how they see the negotiations moving. they have talked about a transition period. the brexit secretary david davis talking about an implementation period and it would be interesting to see what they actually come to in the end and whether or not it fits both sides. the taliban has claimed responsibility for a suicide bombing in kabul yesterday that killed 95 people. another 150 were injured after the attackers blew up an ambulance full of explosives close to foreign embassies and the police headquarters. it's the second major attack in the afghan capital in a week. secunder kermani has the latest from kabul. the authorities have been working throughout the night and into the morning, to clear up the scene of the explosion. they're not allowing us past this cordon at the moment, but you can still see some of the damage that was caused. the suicide attacker was driving an ambulance packed with explosives. he managed to get past this first checkpoint, but then when he reached a second one, and was apparently questioned, he blew himself up. it's not exactly clear what his target was. a police building is right opposite the scene of the blast. the indian embassy is also just slightly further up the road. but, as is often the case, it seems that a large number of those killed and wounded in this terrible incident are civilians. translation: i was sitting and working on the computer, and suddenly i heard a huge bang. then the whole ceiling fell down on top of me. this attack comes just a week after the taliban killed more than 20 people in another attack on the intercontinental hotel in kabul. they've claimed responsibility for this explosion, too, which has been widely condemned by both leaders in afghanistan and across the world, including the us president, donald trump. the security situation in afghanistan, and in particular in kabul, seems to be getting a lot worse. militants seem to be focusing their efforts on targeting the capital, rather than on fighting security forces in rural areas. but to give you an idea of the level of bloodshed in the country, more than 2,000 civilians lost their lives in the first nine months of last year alone. the headlines on bbc news: police are trying to establish how many people were in a car which hit and killed three teenagers in west london on friday. after the raid at the headquarters, the russian opposition leader alexei navalny has been detained by police ata navalny has been detained by police at a rally in moscow. president trump says he would have taken a different attitude than theresa may towards the brexit negotiations. sport now and let's get a full round up from the bbc sport centre. including the tennis. federer has done it again! he has. for a 20th time roger federer has won the australian open, his 20th grand slam title and record equalling sixth at the event in melbourne. he beat marin cilic over five sets. the warning signs were there for all to see, 20 grand slam is the prize for the swiss. already the most successful male singles player of all—time, what an arena in which to surpass another milestone. never one to waste time, a fast start is something of a trademark for the 36—year—old, his forehand looking as strong as it ever has. just 2a minutes into the match and a first set point you needn't give roger federer a second chance. amid the heat, somehow keeping cool. but what isa heat, somehow keeping cool. but what is a final without a fight back? cilic, magician in his own right and as the six best player in the world, he has every shot in the book. so spellbinding, though, is federer‘s tennis, you can never truly cast him aside. how often over the years have we seen him hammering down an ace to regain the lead, even with the mighty thor watching in the crowd ? with the mighty thor watching in the crowd? by with the mighty thor watching in the crowd ? by no with the mighty thor watching in the crowd? by no means finished, cilic launched a fifth and final set. this was to be federer‘s day, the first man to win 20 grand slams and a sixth australian open title. of course, winning isjust an absolute dream come true, the fairy tale continues for us, for me. after the great year i had last year, it's... after the great year i had last year, it's. .. it's after the great year i had last year, it's... it's incredible. cheering emotions running high. 20 already, how many more can this great champion win? james burford, bbc news. england have beaten australia in a dramatic fifth and final one day international. they bowled the aussies out and won by 12 runs. there were a lot of decent starts for england's batsmen butjoe root was the only man to pass 50, eventually getting out for 62. and without him they didn't last much longer — bowled out for 259. australia started their run chase well, marcus stoinis made 87 but when he was out, wickets quickly tumbled. three wickets from moeen ali, including a great caught and bowled. and then five for tom curran meant australia were all out for 249. england win the series 4—1. chelsea host newcastle in the fa cup today. it's the pick of the all premier league clashes in the fourth round but both sides are expected to make changes from their usual line—ups. newcastle are prioritising their fight against relegation while chelsea are hoping to bounce back from their carabo cup exit to arsenal last week. every competition is important. the carabao cup, we tried to go to the final. and reached the semifinal. then we lost against arsenal. now, there is another competition, the fa cup. as you know, very well, this competition is very difficult. we tried to go to the next round. but, as you know very well, there is also an opponent and the opponent has the same idea. that's the first of two fourth round ties in the fa cup today. the other sees premier league leaders manchester city go to championship side cardiff. and that game is live on bbc one this afternoon, coverage starts from just after 3.30pm. you can hear it on 5 live as well. and every goal that's scored in that game and any other fa cup game from the weekend will be on the bbc sport website. that's all the sport for now. i'll have more in the next hour. thank you. more than 16,000 people have signed a petition to reinstate walk—on girls at all professional darts corporation competitions. it follows a decision by the corporation that it will no longer employ women to escort male players onto the stage. that move came after discussions with broadcasters and its been welcomed by campaigners for gender equality in sport. paris remains on high alert, with water levels continuing to rise along the river seine. the country has seen some of the heaviest rainfall for a century, and the river is expected to rise six metres higher than normal. our europe correspondent kevin connolly has the latest from the french capital. predicting extreme weather is always problematic. the river level is continuing to rise, but the maximum point it is now expected to reach is not as high as it was a couple of days ago and it's thought not likely to reach the levels we saw during the floods of 2016, for example. the people of paris and tourists are adjusting to the swollen river. the police here have issued a warning that you shouldn't swim or go canoeing in the river, not a warning that most of us, of course, have needed. this has been a winter of exceptional rain in france, some regions have seen levels they have not seen since the 19505. so, the peak of the river seine's flooding is likely to be reached some point between sunset on sunday and dawn on monday morning but the consequences of this, especially in communities further out in the seine valley, where there has been realflooding, will take weeks or months to resolve. a team of elite mountaineers has rescued one of two climbers stranded near the top of the pakistan's most dangerous mountains. french climber elisabeth revol was found during a high—risk night rescue mission on nanga prabat, which is also known as "killer mountain". the search for her polish climbing partner tomek mackiewicz has been called off due to bad weather and treacherous high—altitude conditions. with me now is masha gordon, a fellow mountaineer and friend of elizabeth revol, and who spearheaded a crowd—funding campaign to help with the rescue attempt. first of all, thank you very much for being with us. extraordinary, you raised how much money? £100,000 within a day. and with 4000 individual donations. it's been the solidarity of the community, extraordinary. this was when you realised you had to do a rescue, that you needed the funding for it? absolutely. pakistani authorities demanded $35,000 upfront in cash. in fa ct, demanded $35,000 upfront in cash. in fact, we demanded $35,000 upfront in cash. in fa ct, we lost demanded $35,000 upfront in cash. in fact, we lost a day of rescue because we didn't have cash in hand. once the fund raising was underway, we could demonstrate we had the money. when did you first realise she was in trouble, that the pair of them were in trouble and you needed to do them were in trouble and you needed todoa them were in trouble and you needed to do a rescue? we received a text on thursday night around 7pm london time, saying that tomek, after the summit, got snow blind and develops severe frostbite and they needed a rescue. in the following 72 hours, we we re rescue. in the following 72 hours, we were scrambling to get the money going and to get the helicopters necessary for that attempt. we were extraordinarily lucky to have a very competent team of climbers doing a historic ascent of k two. we were able to pick them up in the helicopter yesterday and mount that ascent. we had just been seeing some of the pictures of elisabeth and her friend. sadly, the rescue attempt for herfriend, tomek, that has been called for now? correct. elisabeth had to make a very heartbreaking decision of leaving him at 7200 metres. he was in an agonising condition and he was in a coma, one could say. she started her descend to try to get the rescue attempt underway. she had no tent, no sleeping bag, because they were doing the light alpine style attempt. she had to stop at 6700 metres herself, because she started developing frostbite. tell us about this mountain. we said it is a killer mountain, why is it so dangerous and why on earth do people wa nt to dangerous and why on earth do people want to climb a lethally dangerous mountain? i have to make a statement, both of them are one of the best mountaineers, she is one of the best mountaineers, she is one of the best mountaineers, she is one of the best female alpine ears. people are driven by bequest. she became the first woman to make wind ascent, this is the ninth highest mountain in the world and winter ascents are done alpine style without any support in —40 temperatures. done alpine style without any support in -40 temperatures. what went wrong this attempt? lack of preparation? bad luck, the weather? absolutely not. it's the human body. when you are climbing without oxygen at such altitude in such temperatures, anything could happen. the reason she got into trouble was because he got into trouble and she had to stay back and help him down. she brought him down 300 metres and she realised that was not going to happen. what condition is she in? have you heard? we had good news that she landed in islamabad about an hourago and that she landed in islamabad about an hour ago and she is on her weight to be treated for frostbite. she developed frostbite on three toes in her foot. she is developed frostbite on three toes in herfoot. she is incompetent care and we hope for the best. —— she is in competent care. that is good news. tomek rescued during that late night high risk rescue as nanga prabat. night high risk rescue as nanga pra bat. thank you night high risk rescue as nanga prabat. thank you for being with us —— elisabeth rescued during that late night high risk rescue attempt. more news from russia. we told you about the arrest of alexei navalny and we can show you more

navalny. dramatic developments. to recap, he was wrestled into a patrol wagon just moments after he appeared at one of those rallies in order to urge voters to boycott what he said would be a rigged presidential election in march. now, we will check out the weather prospects. hello. it may not be too tempting to step up it may not be too tempting to step up but if you do, you are rewarded by the
