He was arrested as he attended a demonstration in moscow supporting a boycott of the president ial 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 im the head of the Anti Corruption fund and i was a president ial candidate, but first and foremost, im a citizen, who wants to have normal election and who is not prepared to take, any longer, all this nonsense thats been going on for the past 18 years. And to extend this nonsense for another six years. Well, lets 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 president ial election in march. Alexei navalny has said he believes that president ial election will be rigged. Thats 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 shes concerned, that direction of travel has only been going in one single direction and thats, 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 dont elect and we cant remove. That is something other people have also talked about. Weve heard today from jacob rees mogg, who has spoken about this time and again, a backbencher, a eurosceptic, and he says as far as hes concerned, he thinks the problem is that there is no clear direction, theres 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, theres no clear destination, either in the governments mind or indeed agreed with the European Union. And theres 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 didnt 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 hes concerned, for the party to come together. Its the conservative family left, right and centre, because were 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. Thats what the various strands of the conservative party think and weve 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 were 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 were 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. Thats Jeremy Corbyn. The Prime Minister has been criticised for the way shes 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 Trumps part. This is what he said. Do you believe that were in a good position, britain . A lot of people are still very iieivous, very anxious. But hearing the president of the United States saying, hey, theres plenty of trade coming from me, thats a big deal to people in britain. Well, would it be the way i negotiate . No, i wouldnt negotiate it the way its 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 its 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. Its 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. Theyre 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. Its 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. Theyve 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 LeaderAlexei 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 lets 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 neednt 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 federers 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.
