And coming up on sportsday on bbc news, england and scotland begin the netball world cup with wins, but Northern Ireland are thrashed by defending champions australia. Good evening. The metropolitan police has begun a criminal investigation into the alleged leak of official communications from britains outgoing ambassador to the United States. The furore over the contents of sir kim darrochs emails, which were highly critical of the trump administration, caused the white house to refuse to work with the ambassador, and eventually led to his resignation. Scotland ya rds Counter Terrorism command will lead the police inquiry. Our correspondent dan johnson reports. Who leaked the documents that parted the president and ambassador and put the president and ambassador and put the special relationship under strain . How did our man in washingtons frank assessment and up splashed in the mail on sunday . Sir kim darroch privately described the white house as dysfunctional, donald trump as insecure and inept. Within days the ambassador announced he would leave his washington residency, after the president fired back, calling him stupid and pompous, making clear he wasnt welcome. A whitehall enquiry started to root out the league about tonight the metropolitan police announced it would take over. The assistant commissioner said there was even a direct appeal. Im assuming that it is a function of how seriously its being taken, the damage to Britains National interests here, and i think obviously the police have more investigative power, more tools at their disposal to find the culprit. I think its very important to find out who the perpetrator is. Today the president was trying to be nice with some warm words for sir kim. The president was trying to be nice with some warm words for sir kimi wish the British Ambassador well, but theyve got to stop the leaking problem is they are, just the way we have to stop them in our country. Stopping leagues is one challenge, finding the source of this one will be tough enough. Dan, just clear why the Counter Terrorism command is leading the enquiry . Because it touches on matters of National Security and the police are investigating potential breaches of the official secrets act, giving an idea of the level it has reached, and an idea of how complicated the investigation could be and how long it may take. There was a time when civil servants, special advisers and politicians would cheer at the announcement of a league enquiry because they knew that it would lead nowhere. But there is a warning from the police that any further revelations, could constitute breaking the law and we get an indication of how seriously this is being taken indication of how seriously this is being ta ken because indication of how seriously this is being taken because no doubt this has been an embarrassing and unsightly week for british diplomacy and there seems to be a determination to find out who is behind it. Thanks. In an exclusive broadcast interview at downing street, theresa may has told the bbc she will leave herjob as Prime Minister in ten days time, with a mixture of pride and disappointment. She said she didnt recognise herself, in the characterisation of critics, and admitted shed underestimated parliament over brexit. She said it was incredibly frustrating, not to have been able to get her brexit deal approved, but she was proud to have served as Prime Minister. Our Political EditorLaura Kuenssberg reports. A rare glimpse in the private world of number ten. Time now to reflect. Its three years almost exactly since you. It is, yes. It hardly seems possible, the time has flown by, but please do have a seat. Whats it like living above the shop . Its very convenient. But its, you know, at any point in time you can obviously get a call, people can be bringing papers up to you. Its really, in a sense, its a place of work. The red box is done in the evenings. It was here, of course, that i took the phone call about the terrible terrorist attack in manchester. Its really absolutely chilling when you get a call like that. There have been so many difficult moments. How did you manage to get through it all . To be honest, i dont know, i guess its just sort of me. Its important that ive had philip, my husband, is hugely supportive. The other thing is just to keep a vision on what you are trying to get to and what you are trying to achieve. Was there ever a moment where you sat in here at the end of a hard day and thought, i just wish it was over . There were moments when i sat here and i thought i wish wed got brexit over the line. I wish wed actually managed to achieve that. I felt at home here as Prime Minister. But its not obviously the home that philip and i built up together. And it is, as ive said, very much a place of work. But there are happy memories, because it is an immense privilege to be Prime Minister of the united kingdom. Its a huge honour, it has a huge responsibility. You were often accused by your opponents of being too buttoned up, being too closed. Well, this is always a difficult question because i dont recognise myself in some of the descriptions that people give of me. Nobody likes to have descriptions of them that they dont think are right. But thats what happens in politics, you know . What do you think you will feel when you leave this building for the last time as Prime Minister . I think itll be a mixture of pride at having done the job, but also a degree of disappointment, because there was more that i wanted to do. Forced out by bust ups in this cabinet room and outside over brexit. Why do you think it didnt happen . I thought that parliament, having voted to give people the choice, 80 of the people in the 2017 general election voted for parties that said they would respect the referendum. What i had underestimated was that there were people who were in entrenched positions. On the one hand, some people whod always campaigned for brexit but didnt vote for the deal, because they had a particular vision of brexit and they were sticking firmly to that vision. On the other side, people who said they didnt want to leave with no deal, but werent prepared to vote for a deal. I underestimated the unwillingness of parts of some people in parliament to compromise. What about your own responsibility, though . What people say to me is on the one hand that i stuck too firmly to my red lines, and on the other hand people say, sometimes the same people, say that i gave up too much, i compromise too much, and both of these cannot be true. Do you think there are things you got wrong though . One could always look back and say, if id sat down and talked to people more. I spent a lot of time talking to colleagues, trying to understand from colleagues exactly what it was that was creating a problem for them. On both sides it was incredibly frustrating. What i hope is that my successor now has the job of bringing a majority together in parliament. Your colleagues who you sat with round this table, a lot of them were also quite fond of saying what they thought, which wasnt exactly the same always as you thought. You must have been furious at the number of leaks that came out of this cabinet. Every decision, every position the government took was a collective, agreed position, agreed by cabinet. But it must have driven you mad, surely . Good government, good cabinet government, depends on collective responsibility. But i think once we have left the eu and government can get forward over that brexit issue, collective responsibility needs to return. You lost your majority in 2017. Do you now regret calling that election . Can you say that . No, i dont regret calling the election. I regret running a campaign that wasnt really me. There were other things. I probably actually should have done the tv debates. I remember you said so clearly in your campaign im theresa may and im the best person to be Prime Minister. Do you still feel that that was the case . By definition im not going to say, no, i wasnt the right person. I do believe i was the right person to take this on and to take the conservative party. Im proud of the fact that our balanced approach to the economy means we see employment at record levels. Well be injecting that extra £20 billion into the nhs. Were building more homes for people. But then im also proud of giving a voice to the voiceless, of championing some causes that otherwise would be unfashionable. What will you miss . Ill miss the opportunity to be able to go and sometimes just say thank you to people for what they are doing for this country. You know, i hope that whoever people are, whether they voted for the conservative party, orfor other parties, whether they have they were leavers, remainers, whatever they felt, i hope they will feel that in everything ive done ive always done what i believe to be in the national interest. Her picture will soon be on the wall on the famous staircase. What do you hope people will remember of you in years to come compared to all these other Prime Ministers . The first thing i hope is that people will recognise the second female Prime Minister. And i actually hope in years to come there will be more women on the wall as Prime Minister. Not the next time. And so much of what theresa may hoped for is unresolved. She departs a Prime Minister who ultimately failed, but a Prime Minister who tried. Laura kuenssberg, bbc news. The two men hoping to succeed theresa may as Tory Party Leader and Prime Minister borisjohnson and jeremy hunt have been cross examined in interviews by andrew neil for a special bbc one programme this evening. With more on what they said, heres our deputy Political Editor, john pienaar. They came expecting to be tested, and they were. Jeremy hunt first. He said brexit may take a little longer than october the 31st to deliver, but how long . Days, months . Maybe longer, it turned out, than hed like. If its on or around the 31st, it has to be before christmas. I would expect 50, yes. Expect so . But you cannot say for sure. Is there any chance we could still go into 2020 and still be a member of eu . I dont believe so, no. Hmm. But you dont rule it out . I dont believe that would be the case because. Well, this is why people dont really trust you on this. What people get with me is a Prime Minister who will get them out of the eu more quickly. Why . Parliament could block brexit with no deal, an election, the only way to break the deadlock. Who is the Prime Minister who is most likely to get us out of the eu quickly . My worry is that if people vote with their hearts, perhaps, instead of their heads, we will end up with a general election before we get to brexit. Over to the frontrunner. Borisjohnson and his brexit pledge. Out on time, do or die. But what if a deal was within reach . Nobody believes you would walk away in these circumstances. Be honest with the british people. No, i think its very, very important that we get ready to leave on october the 31st, come what may. Mrjohnsons not always been easy to pin down, although that was clearly the plan today. No, no, no. No . You will follow the questions i want to ask, not the ones you want to be asked. All right. And the latest row, had he helped drive out britains Us Ambassador by failing to back him on tv after he fell out with donald trump . He said that what somebody had relayed to him had certainly been a factor. So your lack of support for him was a factor in his resignation. I think that unfortunately what i said on that tv debate was misrepresented to kim. Will you be as craven if you were Prime Minister . Ive been. Neil, towards the United States of america, craven . Towards anybody who is powerful in the world. Dont be ridiculous, if i may say so. Hes still the favourite but in ten days well know whose answers will shape britains future. Boris johnson orjeremy hunt, the Big Questions on when and how to deliver brexit, on which tax and spending promises to keep, and which to quietly set aside. Therell be no dodging those questions once in office. Until then, its fair to say that neither man really knows the answer to some of those Big Questions themselves. John pienaar, bbc news, westminster. And if you want to know more about each candidates policies, you can go to the bbcs reality check website. Thats at bbc. Co. Uk realitycheck. A man who stabbed a passenger to death in a row on a train has been found guilty of murder and jailed for life.

From clandon station, he headed here into the fields. But he was soon spotted by a local resident here, who said he looked distressed and that he was sweating.

After sentencing, the police gave a statement with mr pomeroys wife lana alongside.

But the day before the killing, a psychiatrist assessed him, concluding he was not a risk to himself or others. Just 2a hours later, Darren Pencille committed murder.

Human rights organisations are calling for an end to el salvadors total ban on abortion laws which see women and girls routinely imprisoned, even after enduring stillbirths and miscarriages. On monday, a 21 year old woman, whom supporters say had a stillbirth, faces a retrial on charges of killing her baby. She has to prove she didnt induce an abortion.

From the capital san salvador, our International Correspondent orla guerin has sent us this special report. San salvador. A city where catholicism has deep roots, and where the church has had a commanding influence, and helped to ensure the total ban on abortion. A ban that has criminalised women like theodora vazquez. She went into labour alone at work and called an ambulance which never came. Theodora says she fainted during the birth, and came to surrounded by police, accusing her of killing her baby. Last year, her 30 year sentence was commuted and she walked free, to be reunited with herfamily, after a decade behind bars. Human
