The patisserie chain patisserie valerie. England prepare to take on cameroon in the womens world cup. And we look atjohn bercows decade as speaker. That and more on the week in parliament. Good afternoon. Welcome to bbc news. There is continued focus on Boris Johnsons private life after he failed to answer questions at a conservative leadership hustings as to why police were called to his partners flat after reports of around. Mrjohnsons supporters say he should bejudged on his policies, not his personal life. Detractors such as liam fox said today, mr johnson should have given an excellent nation about what happened. Often in the headlines, this time for the wrong reasons. After police were called to the flat borisjohnson shares with his girlfriend, mrjohnson has been reluctant to explain. I dont think they want to hear about that kind of thing, er. Applause. But this senior tory, whos backing mrjohnsons leadership rivaljeremy hunt, said an explanation would be sensible. Its always easier to just give an explanation, but i think the key thing is then how you get on the issues. What we cant have is it being a distraction from explanations about wider policy. Mrjohnsons team say he has never answered questions about his private life and wont start now. His supporters say we should move on. The police were called to an incident and what they say . They said everybody was safe, everybody was well, there was no concerns that the officers had and there was no cause for any further action. Given thats what the police said and its clearly a private incident, i wasnt there, you werent there, i think we should just leave it at that. But the front runner to be Prime Minister is no stranger to controversy. Scotlands first minister suggested he was racist for comments hes made in the past, like comparing women wearing the muslim veil to letterboxes. Boris johnson has made overtly racist comments, people who are prepared to make comments like that cant suddenly throw their hands up in horror when people call them out for it and say that they appear to be racist as a result of it. The first thing we need to do you know what it is we need to get brexit done. At the heart of the leadership contest are questions about brexit. Both sides made their case at a hustings in birmingham yesterday. Liam fox suggested some of borisjohnsons claims about what would happen if we leave without a deal are wrong. But mrjohnsons supporters say their man can deliver. We need a leader with a determination to follow through, go through to the 31st of october, leave, preferably with a deal but without a deal if necessary. He will be asked many more questions over the next few weeks, but for now, hes the man to beat. Nick eardley, bbc news. Mick is here with me. Picking up on what liz said. There was a sense among the activists yesterday at the hustings, ask the questions and then move on. Why does the attention not seem to have moved on . Mrjohnson wa nts to seem to have moved on . Mrjohnson wants to move on, he has made it clear he does not want to talk about it. His team think that he has never spoken about his private life so why would he now . But there are some in the political world who think it is a question of character. Boris johnson could be Prime Minister in just over four weeks time. Some people say we deserve to know more about the character of the person who could be leading the country is. That is the point the labour party have been making this morning. One of the shadow ministers said, is this man fits to be by minister . Im not so sure. So im not sure the attention will go away. Jeremy hunt is in scotland and aberdeen, he was asked about whether not this question of character came into things. Interesting, because clearly he does not want to be drawn on the specifics of whether Boris Johnson was right to not answer questions about what dead or did not happen on friday morning. He is making a general point which alludes to Boris Johnson, which is saying that there isa johnson, which is saying that there is a need for people who want to be Prime Minister to come and answer questions, to put the character forward for scrutiny and jeremy hunt clearly doesnt think borisjohnson is doing that. Clearly there is difficulty for the conservative party in arguing for the future, the party has to address the immediate past. Both candidates have had to trash the government of which they have been part. Both voted for the Prime Ministers deal at the final time of asking. Both say there is good things and bad things, but the main thing we need to get rid of as the backstop. But there is no process or clarity about what they would do that would allow this to happen . No eureka moment suddenly where westminster says why didnt we think of that . There is annulment of that, it is negotiation, they will need to see we have to go to brussels and say this is something we have to change, we have a new Prime Minister, the dynamics of change in parliament. But as you say, no one is clearer about how you get from a to b on that. We are in this series of 16 hustings stretching out over the next few weeks. Quite an intense period for the candidates themselves. Never mind the factjeremy hunt still foreign secretary. In terms of the balance going out. That does not happen untiljuly nine . And then we get the final announcement by the 22nd. What is the sense that there has to be a debate going on between the two men . This was something jeremy hunt said yesterday. As anything to say the bodice campaign accept that argument . That they have to go head to head before they get the ballot paper . Im not sure there is much of an acquiescence to mr hunts demand, when he has repeated over the last few days. That scrutiny is key. Team johnson think there is a long time to scrutinise there is a long time to scrutinise the potential Prime Ministers because they are going to the 16 hustings around the country. They say that is the proper place for this to happen, their main concern is that you end up with blue on blue action, conservatives are fighting conservatives as mr hunt tries to make up the ground he needs on mr johnson. At the same time, i dont think the calls for that scrutiny are going to go away, either from the media, certain mps or whether it is from the hunt camp. There seems to bea is from the hunt camp. There seems to be a real desire to see, there is a desire for it. They said we didnt properly scrutinise a religion act last time and it didnt work out well. Our leader last time. Reports in the us say america launched a cyber attack on iranian Weapons Systems on thursday, as President Trump cancelled air strikes on the country. Several sources including the washington post, said the attack disabled Computer Systems controlling rocket and missile launchers. The action was in response to the shooting down of a us drone in the strait of hormuz last week. A senior British Foreign minister has arrived in tehran today for talks amid growning tensions between iran and the west. Jane Frances Kelly reports. America appears to have used cyberspace rather than air power to retaliate against irans elite military forces. Us media reports that the online operation was designed to cripple Weapons Systems like this, used by the Islamic Revolutionary guard to shoot down an american drone last thursday. The wreckage was later put on display by tehran. It came as President Trump publicly declared he had pulled back from an air strike on iran because it would cause a loss of life. What it has to do with, very simply, is the fact is we are not going to have iran have a nuclear weapon, and when they agree to that, they are going to have a wealthy country, they are going to be so happy, and im going to be their best friend. I hope that happens. But tensions remain high. The downing of the drone comes after a series of attacks on tankers travelling through the busy shipping lanes of the gulf, which washington has blamed on iranian forces. Mr trump pulled out of the Iran Nuclear Deal last year and has announced new sanctions will begin on monday. A British ForeignOffice Minister meeting with diplomats in tehran today has called for a lessening of tensions. Within days, iran is likely to start breaching some technical limits of the agreement. This puts pressure on european leaders including germanys chancellor, who remains committed to it. Translation i say that the political solution should not just be a hope but it should be worked towards with the utmost seriousness, because i believe it should only be a political solution. Mr trump is using both the stick and carrot. He is piling on the pressure while offering the hand of friendship. And so far iran has shown little inclination to bow to his will. Team sport players are as good at endurance as Long Distance runners and as powerful as body builders. Thats according to Research Carried out by manchester metropolitan university. The key is to combine strength and endurance training. Im joined now via webcam by the lead researcher of the study professor hans degens, professor of muscle physiology at manchester metropolitan university. Professor, thank you for being with us professor, thank you for being with us this afternoon. First of all, what is at the heart of your findings and how surprise where you buy them . At the heart is that Team Athletes who combine endurance and resista nce athletes who combine endurance and resistance training are doing as well as our athletes in the power measures, and were doing as well in endurance measures as endurance athletes. This is somewhat surprising because the current concept is there is an interference effect between endurance training and resistance training. This means that if someone is doing resistance training and wants to build up his or her muscle, and then adds endurance training to that, the effect of the resistance training will be reduced. That is the idea. If someone wants to build up his or her endurance, and then as resista nce her endurance, and then as resistance training to it, the idea is that the gains from endurance will be reduced. Our Study Suggests thatis will be reduced. Our Study Suggests that is not the case and that the tea m that is not the case and that the Team Athletes who combine both types of training are doing as good as endurance specialists and also as good as power specialists. So your advice would be that in some sports people need to adapt their training and not be frightened of doing the thing that they might have in the past worried would have a negative impact on their overall performance . Ended . At the moment we are working on body builders, we had problems in recruiting people to participate in an endurance Training Programme because of this idea that it is ruining, and we said to them we do not have evidence that this happens but also if you participate it will be probably good for your health because you have a high capacity to burn fatty acids and we know that the capacity to burn fatty acids is quite a nice thing. In terms of applying this to those of us whose levels of activity do not go anywhere near a sporting field or a racetrack, or indeed a gym if im honest, but do things like walking and climbing, all those kinds of activities, are there things that you can apply to everyday activities . Yes, the things you could do in daily life is do things like gardening, walking, maybe a bit of jogging, like gardening, walking, maybe a bit ofjogging, asa like gardening, walking, maybe a bit ofjogging, as a rule of thumb you could say that any exercise that is ata could say that any exercise that is at a pace where you can have a conversation just, so a at a pace where you can have a conversationjust, so a bit difficult to convert but you can just do it, that is the right place to maintain your physical activity. Also throughout your ageing process because that is a big thing, when you become older, you become weaker, your endurance becomes problematic and ultimately you may have problems with even rising from a chair and of course, in this particular case, strengthening muscles with resista nce strengthening muscles with resistance exercises is highly beneficial. Adding modest working well also help. Encouraging news. What about for Team Athletes, could this affect their training schedules through the year, because this kind of information could re evaluate what we do . I guess those people should not be afraid to add endurance training to their resista nce endurance training to their resistance Training Programme and it can be strenuous, and also others add Strength Training to the endurance programme. So the study shows there is no reason to believe that the gains from one sort of training are lost by adding the other type of training. So it can be combined and it can gain the best of both, so to say. Is it changing your activities as . I like Long Distance cycling and there is no reason not to add resistance exercise, so yes. A real pleasure to speak with you professor, thank you very much hans degens. The headlines on bbc news. There is continued focus on Boris Johnsons private life after he refused to answer questions following reports of a row at his partners flat. The United States has reportedly wants a cyber attack on iran. That was after president trundled out of your strikes against iran. Five people arrested from patisserie valerie. Millions of residents of istanbul are voting in a rerun of an election to choose a mayor. The opposition candidate narrowly won the vote in march but it was an old after complaints by the governing party. President dick critics of the president have accused him of pressurising this is a privilege to test for the president , the key figure on the world stage. This is the president s key city, he once ran it as mayor. Whoever wins istanbul when starkey has said. Wins turkey. If you lose it would start talks of whether it is the beginning of the end of his political rise over the last 25 yea rs. His political rise over the last 25 years. The opposition has managed to tap the widespread desire amongst its supporters for change with a positive optimistic message. This is a watershed moment for turkey, this crucial country and its most powerful leader of modern times. The north Korean Leader has said he has received a personal letter from donald trump. Kim jong received a personal letter from donald trump. Kimjong in city received a personal letter from donald trump. Kim jong in city would definitely talks have been stalled after the failure of the hanoi summit. Three other officials were killed in two separate attacks. Here, five people had been arrested as part of a Fraud Investigation following the colla pse a Fraud Investigation following the collapse of the chain, patisserie valerie. It folded in january with the loss of 900 jobs. Our business corresponded is here. There have been arrests before, what do we know about this time . We can go back to the start. Injanuary, patisserie valerie collapsed. This was after the discovery of a black hole in its accou nts the discovery of a black hole in its accounts which was eventually valued at £94 accounts which was eventually valued at £91; million. In october, someone had already been arrested, this was chris marsh, the financial director. He was arrested and released on bail. That was part of an investigation by the Serious Fraud office into what happened, and how patisserie valerie came to collapse in that way. It is worth noting the chain has not disappeared. You can still see them, some are still trading but others are close up so a mixed picture . When the firm went into administration, some of them had already closed, about 70 stores so 900 people lost theirjobs. A firm bought what remained out of administration which is why it is still trading in another form. Administration which is why it is still trading in anotherform. If administration which is why it is still trading in another form. If we go back to this Serious FraudOffice Investigation into into how it literally collapse. After that first arrest in october, we have had it confirmed that five other people have also been arrested. That happened on tuesdayjust going and we are told that was part of a joint operation with hertfordshire, leicestershi re operation with hertfordshire, leicestershire and london. The Serious Fraud office have not said anything else about who these people are and exactly why we are being arrested. Thank you. Researchers have said they had uncovered a campaign to plant for content on twitter and facebook. They say the material originates in russia. Britain spying on america. Anti immigrant sentiment in germany. The involvement of irish paramilitaries in a russian spy. Serious stories. All of them fake. A campaign on 30 Online Platforms was designed to Stoke International tension. Researchers from the atla ntic tension. Researchers from the Atlantic Council see it originated in russia. Most of the post failed to gain traction. With russia repeatedly accused of trying to destabilise democracies, the latest revelations will surely cause further alarm. Moscow has repeatedly denied using the internet to spread fa ke denied using the internet to spread fake news and also alter public opinion. But politicians in europe and the United States see the kremlin is guilty of trying to influence elections. In 2017, fake news was
