craig williams and laura saunders, on the date of the general election. on the campaign trail, labour is setting out changes to the process for someone to legally change their gender. the party is also offering to provide hundreds of thousands more dental appointments on the nhs. the lib dems release their analysis on hospital waiting times. leader sir ed davey claimed the country has ten days to save the nhs. the snp'sjohn swinney will give a speech on brexit. while the dup is launching its manifesto in northern ireland. so it is a busy day for all of the parties today. we'll touch on all of the above in this programme, but let's start with the election betting investigation. here's tobias elwood speaking to the bbc radio 4 today. this betting saga has been deeply unhelpful, self—inflicted distraction, and in what world they thought this was acceptable is beyond belief. the prime minister has expressed his anger, he said that at the leaders�*s question time debate. it has been a turbulent period in british politics in recent years, with trust with the british people having to be rebuilt. the prime minister has navigated us into calmer political waters, fiscal responsibility has returned. so this is so frustrating with ten days to 90, is so frustrating with ten days to go, we have got to go back on point. let's give the nation greater reassurance that i think it wants to see. that this never happens again. let's introduce clear roles, as you have in the banking rules and in the city, connected to the stocks and shares. let prevent any politician or party from placing bets in the future. that would send a clear message to the public. that this is being taken seriously and will not happen again. being taken seriously and will not happen again-—

slater on the spanish island of tenerife has now entered its eighth day. the 19—year—old went missing after attending a music festival last weekend. mairead smyth has the latest. the impression we are getting on the ground is theirs. it looks like the police searches are less concentrated than they were before. there are searches taking place around the holiday home where jay slater went with two men in the early hours of monday morning. is that because they are spreading out? are they moving away from the mountainside? are they going to villages like santi ot del turday, where a woman has contacted the police apparently to say they saw someone in that village later that day. we have not seen any lease activity there. one man we had spoken to said he did not know anything about the disappearance until posters went up in the village yesterday. that is another thing we have seen. friends and family putting up posters. doing these small things like going down to the bars and holiday resorts where jay slater was clubbing last week, putting up posters there, putting things on social media, even going out to carry out searches of their own. we have seen complete strangers do that, too. people travelling from lancashire, where he is wrong, and london, coming to tenerife. the police say they won't comment on ongoing investigations, so it is very hard for us to tell you how they are operating, how their searches are going and how successful they are. what we do know, of course, are that lancashire police have offered assistance, but they say they are very happy with they say they are very happy with the resources that they have. that was fiona trott. apologies for that. flights have resumed at manchester airport a day after power cut caused major disruptions for tens of thousands of passengers. people waited in long lines, and some airline passengers were held on runways for several hours. some flights were diverted to other airports. it comes at the start of the busy british summer holiday season. the managing director of the uk's third busiest airport has apologised to passengers. live now to manchester airport and our correspondent lauren moss is there. bring us up to date with what is happening today. bring us up to date with what is happening today-— bring us up to date with what is happening today. bring us up to date with what is ha enin: toda .

happening today. good morning. while it is a sunny and steady start to - it is a sunny and steady start to the week here at manchester airport. just behind me are terminals one and two. we have seen flights coming in and taking off all morning. in a couple of minutes, a flight is due to leave zack and asked, another for palma in majorca. if light isjust coming from dublin as well. things are moving here and getting back to normal. but that was not the case yesterday. up to 90,000 passengers affected by what has happened here. there was a fault with a power cable which damage things linked with security, passports and baggage. that meant that many flights, more than 60 were cancelled, over 50 flights that were due to land here yesterday were diverted to other airports in the uk or did not take off. and for theirs passengers who did manage to get away yesterday, many of them went without their baggage. there will be at their destination is now waiting to find out when their holiday essentials will be arriving. that is the priority for bosses at manchester airport today. there is a flight just coming in now. i'm not sure that one has come from. but some that one has come from. but some that have been adding this morning have been delayed from yesterday by some substantial amount of time. what we are seeing today is business very much as usual for passengers due to leave today, that is what the airport are saying, although the advice is to check with your airline before you arrive here. but the priorities are clear the backlog and trying to put those displaced thousands of passengers that should have travelled yesterday, getting them to where they meant to be and catching them up with their baggage as well for those that left. it is the start of the summer season here as well, so people are really going to be working hard at manchester airport to find out what caused that power surge to damage that equipment thatis power surge to damage that equipment that is so key to keeping this airport running as we head into the busiest time of year for the airport. leave for zakynthos. people are starting — airport. leave for zakynthos. people are starting to

depend whether there airline is covered by uk law or their travel insurance says. people will be looking at those policies. most passengers will be entitled to compensation if the flight was delayed by more than 2—3 hours, so people will be checking the small print on that. there were queues outside of the airport yesterday, people talking about how they were inside and they didn't really know what was going on, they sat on the runway and was told their flight was not going anywhere. and indeed, they hope there will not be the case for today and the rest of the case for today and the rest of the summer. things are running as planned on the whole here at manchester airport for passengers who were due to fly today, they should not be affected. but the advice is to check before you travel because this is going to cause quite a hangover, really. and for those passengers there were due to go yesterday but haven't, the priority is getting them through. for those passengers who are abroad without their suitcases, getting them united as well. another flight coming in now. we can see that things are steadily getting back to normal. but definitely, they will be wanting to make sure this does not happen again as hundreds of thousands of people are expected to come through this airport over the coming weeks. thank ou ve airport over the coming weeks. thank you very much _ airport over

somerset has become the first person in the world to trail a new treatment for epilepsy. 12—year—old oran knowlson, who was having multiple seizures a day, has been fitted with a device inside his skull known as a neurostimulator — sending electrical signals deep in to his brain. our medical editor, fergus walsh, has been following his progress — just a warning his report contains some images of surgery and seizures. would you like to try using this? you can. i don't think it wipes off as well, does it? yeah. thank you. oran is 12 years old. he has autism and adhd. mama? yeah? but what is holding him back most is his epilepsy. he's not had a day without seizures since he was three. i had a fairly bright three—year—old that, within a few months of seizures commencing, deteriorated rapidly and lost a lot of skills. oran has multiple seizures day and night. all right, ok. all right, all right. some are so severe, he stops breathing. quinn, baby — i need your help, please. epilepsy seizures are triggered by abnormal bursts of electrical activity in the brain. these can often be controlled by drugs, but oran's form of epilepsy, known as lennox—gastaut syndrome, is so severe nothing has helped. e
