Our top story downing street has reacted angrily after borisjohnson was referred to the Police Watchdog over his friendship with an american businesswoman. Over his friendship the independent office for Police Conduct will look at whether a criminal investigation should be launched into allegations thatJennifer Arcuri was given favourable treatment, including financial grants, when mrjohnson was mayor of london. Our Home Affairs CorrespondentDaniel Sandford reports. Come to london, build your business is your. The american take entrepreneurJennifer Arcuri received sponsorship events run by her company from organisations linked to borisjohnsons office while he was mayor of london. She then went on three overseas trade missions with borisjohnson all of which shed originally been turned down for. The bbc has spoken to several people who were on the trips. They said Jennifer Arcuri seemed out of place, as her companies were less substantial than those of other participants. Borisjohnsons office intervened to make sure that she got on one of the trips to tel aviv, though she paid her own way. I like it its brilliant the allegations of Improper Conduct were originally made in the sunday times and have been looked at by the Greater LondonAuthority Monitoring officer this week. Shes now decided to ask the Police Watchdog, the independent office for Police Conduct, to assess whether borisjohnson should be investigated for the criminal offence of misconduct in public office. The iopc are involved because, as mayor of london, borisjohnson was also in charge of londons metropolitan police. I really think there are so many more important issues like putting more important issues like putting more police on our streets, increasing funding for schools. All of these things are the kind of issues that my constituents and the general public want is to focus on. Ijust do not believe that this complaint is the issue that is being made out to be in the media this morning. The Prime Minister has vigorously denied the allegations. A senior government source said the referral to the iopc was a nakedly political put up job. Daniel sandford, bbc news. Labour have promised to scrap the welfare system of universal credit if the party wins the next general election. The party Leaderjeremy Corbyn will today condemn the system as an unmitigated disaster which is inhumane and cruel. The government says the proposal is irresponsible. In few minutes well be speaking about that pledge to the shadow local government secretary, andrew gwynne. The Scottish First minister, Nicola Sturgeon, has said the snp could backJeremy Corbyn as an interim Prime Minister to prevent borisjohnson from taking the uk out of the eu without a deal. She called for a vote of no confidence in the current government, followed by a caretaker administration. Our Political Correspondent nick eardley is in our london newsroom. Nick, how likely is this to happen . It is one thing Nicola Sturgeon saying she thinks this is a way forward , saying she thinks this is a way forward, but are the numbers there in the house of commons to make it happen . The simple answer at the moment as the numbers are not there because this would need the support notjust of labour, not just the this would need the support notjust of labour, notjust the snp, but the liberal democrats, former tory mps who were chucked out of the party for refusing to back borisjohnsons brexit plan. At the moment, it looks like a bit of a long shot. However, it indicates a nervousness amongst opposition parties that the legislation they pass, which is supposed to stop a no deal brexiteer month, that that is not going to be enough. They are really worried that the Prime Minister might ignore it oi the Prime Minister might ignore it orfind a way the Prime Minister might ignore it or find a way around the Prime Minister might ignore it orfind a way around it, and so the Prime Minister might ignore it or find a way around it, and so they are increasingly talking about this idea of trying to replace Boris Johnson and put somebody in temporarily to go and get a brexit extension, then call a general election. The argument the snp are making privately is that mr corbin comes first, because he is leader of the opposition. But when all of the opposition parties meet on monday, i think they will have a big discussion about potentially who else could do it and get some more support. Thank you for now, nick.

Theres been reports of an explosion near a polling station in the afghan city of kandahar, as voting gets under way in the countrys president ial election. Tens of thousands of Afghan Forces were deployed across the country to counter taliban militants, who had vowed to target polling stations. A number of people were reportedly injured in the blast. The broadcasting regulator ofcom is to investigate the way the bbc has handled a complaint about breakfasts naga munchetty. She was speaking on this programme after President Trump called for four non white congresswomen to go back to their countries. The bbc said naga was entitled to comment about her own experience of racism, but she should not have speculated about the president s motives as that breached impartiality. The bbcs david jordan explained the decision. Unfortunately towards the end of the discussion, she did sort of venture into speculating about what President Trumps motives might have been in making the comments that he made. Theres no doubt that the comment that he made is racist. To say to anybody from a minority ethnic community, from an immigrant community that they should go back to where they came from is just ignorant prejudice and is racism, and she was right to identify it as such. So theres no doubt that the comment was racist. But what she then went on to speculate about, together with dan walker later in the conversation, was what was motivating that. Was it being done for to attract attention or for some other reason . And you can watch that episode of newswatch in full on the bbc iplayer now. Prince harry has said that visiting the most famous site of his late mothers anti landmine campaigning was an emotional experience. He was speaking after walking through a partially cleared landmine field in angola just as diana, princess of wales, did in 1997, shortly before her death. Our correspondent Pumza Fihlani joins us from cape town in south africa. Pumza, was this also a significant moment for the people of angola . Incredibly poignant images. Indistinct and also in angola, that really powerful image that we saw of prince harry walking through a minefield. It was a different area he passed than his mother. Iam afraid than his mother. I am afraid we are going to have to leave it there. We cannot quite hear your microphone. We will try to rectify that and come back to you in little bit later. Apologies. And if you like to back a horse at short odds, this could be the race for you. They dont get much shorter than this the annual Shetland Pony grand national took place at newmarket yesterday. 13 riders, who had to be aged between nine and 13, and under five feet tall, raced over two and a half furlongs. Thats four miles shorter than the full sized race at aintree. 12 year old zac kent won by a nose which must have left the other riders feeling rather low. Everyone feeling low they are beautiful, though, arent they . It feels like you need to adjust the picture ratio on the screen. There we go, there is that nose. Photo finish so dramatic. It is bbc breakfast, believe it or not, it is coming up to 750 two 80 am. When universal credit was first announced in 2010, it was hailed by its architects as a once in many generations reform to the welfare system which would simplify payments and make work pay. Today, the labour leader Jeremy Corbyn will condemn the system as an unmitigated disaster which he will scrap if he gets into power. Were joined now by shadow local government secretary, andrew gwynne. The thing with universal credit was the government acknowledged at the time that rolling it out had been a problem but now it has been established, there is lots of evidence it is working for lots of families. That is not the case. The real evidence is that we are universal credit has been rolled out, it has increased poverty. It has increased hardship. Many families are struggling and children are being pushed into poverty. Food bank use has escalated massively since 2010 and there is a direct correlation between that increase in Food Bank Use and an increase in rent arrears as well. And the roll out of universal credit. It is a broken system and it is a system that has to be scrapped. The government has apologised for that delay in payment but i have spoken for example to jobcentre workers delay in payment but i have spoken for example tojobcentre workers in liverpool, to somebody who broke their leg in manchester, who said their leg in manchester, who said the simplicity of the system when it works beats everything that has come before it. The simplicity of it, if it works, is a good idea and a principle that we supported. The simplicity of it. The problem is it doesnt work. People accrue massive rent arrears that they are then kept perpetually in poverty as a result of that. What we have said is you cannot tinker around with universal credit. The next Labour Government will scrap universal credit. It will ensure that we put families and children first, that we will scrap, for example, the two child limit, the so called rate clause, we will ensure that there are frequent payments and that payments to landlords will be made in respect of rent, to avoid the chronic rent arrears that many people have now accrued. That is the right and sensible thing to do. But people would argue that you negate the benefits of universal credit, which would argue that some people become more financially responsible if they do have to manage their budget over a period of time. We are living in the real world here. Ideal on a free quit basis in my constituency make frequent basis in my constituency with families on real hardship because they have accrued massive rent arrears that would be difficult for them to ever recover. It does not save the public purse. You know, the job it does not save the public purse. You know, thejob i have in the shadow cabinet is the shadow local government secretary. The impact of this poverty inducing policy, which universal credit has done, particularly on children, has led to a massive cost explosion for Childrens Services up and down the country, so it pushes the burden elsewhere on to the public purse. Lets tackle the root cause of child. Lets get a welfare system that works. That is why we will scrap universal credit, we will also scrap universal credit, we will also scrap the department for work and pensions and replace it with a department for Social Security, because the clue is in the name. We wa nt to because the clue is in the name. We want to have a Social Security, a safety net for everybody. That is really important going forwards. You talk about the public purse and the importance of that, how does it help public money to scrap something that has caught a lot might cost a lot of money to set up, a department to be reorganised, a whole new system . Is trying to get the existing system to work as best as it can rather than spending more money to change it not better question mark what youre suggesting has been described as expensive fantasy that will cost billions of pounds. The tory party would say that. There is a Commons Library has said this would cost in the region of about under an £80 million. 180 million . For some of the changes, the immediate changes to universal credit, and scrapping the two child system, would cost around that. We have factored in 300 million. The totality of the changes that we propose would cost £3 billion and we have budgeted for that in our manifesto for the next general election. So it is very complicated but where does that money come from . It has got to come from taxes or some other money somewhere else. We have already said that £2 billion was identified in the 2017 general election to try to fix universal credit, that money is there already in our costings. That will move across to our new plans. The extra billion pounds that we have to find will be fully costed when we get to that general election. We will have a great book, as we did at the last general election, specifying exactly how these measures will be paid for. But look, we are paying through the nose and Childrens Services and local authorities across the country. Tackling Child Poverty will be the number one priority of the next Labour Government. You mentioned they are that there were elements of universal credit that you respect, the idea of it being to work. Will you take on elements of that, the single payment of that, for example . One of the things we are looking at is how you get to the system that we wa nt to is how you get to the system that we want to get to. We recognise it is not going to be a quick fix. We. The roll out of universal credit. But people will argue that you are just criticising universal credit. Youre not being clear about what you will replace it with or where the money will come from. We are being very clear with what we will replace it with. We are saying that we would develop a new Social Security system and would have an interim period where we can actually use statutory instruments, secondary legislation, ministerial direction. What does that mean to people . With they have the same payment . To change the way that universal credit works so that they will have a faster payment, we will get rid of the bedroom tax, we will get rid of the bedroom tax, we will be able to end the two child limit, which has pushed many children into poverty. These are quick fixes that we do not need legislation to introduce. Then we will bring forward a package of reforms for a new Social Security system in due course. 0k, reforms for a new Social Security system in due course. Ok, but it is not entirely clear what it is just yet . Well, we have been very clear about the changes that we would make in the immediate, day one of a Labour Government but the new package of what will replace universal credit will take time. We dont want to get into the mess that the tories have got into, in introducing a massive change overnight. But there are things that we can do immediately to make the Current System work in the interests of families and children. Many thanks, good to see you. Thank you forjoining us. If you are planning your weekend, you need to know what the weather is going to do. There is some sunshine to talk about. It is not a wash out at all this weekend. However, there is going to be some heavy rain around, particularly across parts of england and wales tonight and for a time tomorrow. Some strong winds could cause travel disruption.
