news of another cyber this time affecting several large london hospitals, being described as a major cyber attack. services including the delivery of blood transfusions have been affected, according to memos are sent to nhs staff. we know that the king's couege staff. we know that the king's college hospital and guy's and saint thomases are amongst the hospital is experiencing problems, with some operations reported to have been cancelled or redirected. we will talk to one of a health correspondence about this shortly. more on that story, the breaking story coming up for you. let's continue with the general election campaign. the big news today is rishi sunak and sir keir starmer will go head—to—head in their first televised debate of the general election campaign tonight. the hour—long programme on itv will be filmed in front of a live studio audience. it comes as the conservatives have promised to introduce a yearly cap on the number of migrant visas, while labour has accused the tories of letting immigration get out of control. our political correspondent jessica parker has the details. a home secretary with a point to make. the conservatives say they'll reduce migrant visas year by year, but the party's haunted by highly visible old pledges to bring immigration down. net migration, the difference between numbers arriving and leaving, hit a record high in 2022. we are the only party with a credible plan to professionally manage migration so that it supports the british economy without putting undue pressure on local communities. the tories have broken so many promises to bring down migration, why on earth should voters believe you now? so we have seen a 10% fall in illegal migration because of the actions that i've taken, with the full support of the prime minister, since becoming home secretary. labour's refraining from diving into the numbers game, promising to bring immigration down, but also without saying by how much. on immigration, we have to tackle the central— on immigration, we have to tackle the central issue, which is we need a skilled _ the central issue, which is we need a skilled strategy in this country so we _ a skilled strategy in this country so we don't have to have so many people _ so we don't have to have so many people arriving on work visas. do ou people arriving on work visas. dr?

net migration is far too high. this _ migration every year? net migration is far too high. this government - migration every year? net migration is far too high. this government has | is far too high. this government has lost control — politicians know many voters worry about social change and pressure on public services, but that can rub up against a demand for foreign workers and student arrivals. immigration has long been a hot button issue in british politics but promises to bring numbers down have frequently ended up at odds with reality. and the conservatives may notjust be worried about being squeezed by their own record on this topic, but now an old political foe as well. mr farage, are you standing? well, we'll find out in a moment, won't we? nigel farage yesterday announced he's standing for parliament and leading reform uk. he says net migration should be zero, but seemed to rewrite his party's own policy on air to process certain asylum claims in british overseas territories. which overseas territories would be open to this? i don't think it's terribly practical. what, the policy you've put forward, it's not practical? i think it's a very difficult policy to work, and i haven't put it forward, by the way. why is it on your website? i took over yesterday so give me more than 12 hours and i'll sort a few things out. tonight, in a tv debate, the conservatives' rishi sunak and labour's keir starmer go head—to—head — the two men fighting it out to be your next prime minister. both want to show you, on immigration and on many other issues, that they can take control. jessica parker, bbc news, in westminster. our political correspondent susan hulme is in westminister. afternoon to you. although he will not be on the podium tonight and i wonder how much of a presence nigel farage will be in that debate, certainly in terms of the comments he has made about immigration. yes. he has made about immigration. yes, i think his explosion _ he has made about immigration. yes i think his explosion onto the he has made about immigration. 1l: i think his explosion onto the stage of the election is certainly going to overshadow that. i think certainly the prime minister, rishi sunak, is going to feel the hot breath of what nigel farage has had to say breathing down the back of his neck. it is a moment ofjeopardy for both the people actually taking part in that debate. it is a really intense moment because they are live on air, anything could go wrong, even from a personal point of view, a physical point of view, a slip of the tongue. these things can be re—played and replayed and seen over and over again. however, re—played and replayed and seen over and overagain. however, it re—played and replayed and seen over and over again. however, it is also and over again. however, it is also a huge moment of potential that you can actually achieve that breakthrough moment that will really cut through with the voters as well. thank you very much, susan. let's return to the breaking news i brought you a few minutes ago, the news that several major hospitals in london have been affected by a cyber attack, affecting, among other things, the delivery of blood transfusions. let's go to our health correspondent, sharon barbourfor this. what more detail do you have about this attack?

since russia panic invasion of ukraine, this has been pushed up the agenda —— russia's invasion. ladle the agenda -- russia's invasion. we want our the agenda —— russia's invasion. l want our system to be reliant on clean and home—grown energy by 2030, so we will start at the moment we get in if we are lucky enough to win the election. in setting up great british energy, the national wealth fund and reforming the planning laws that we can get great connections into all our new paris supplies and get the work done as soon as possible. what we are aiming for his saving people £300 on bills per year by the first pilot —— are new powers supplies. we have a lot of struggles to deal with after 14 lot of struggles to deal with after ia years of conservative government, planning system is in disarray, our energy system not doing what we needed to do, so there is a lot of work to be done, but this is one of care's main priorities, one of our first steps is setting up great british energy, so we want to move at pace —— one of keir�*s's main priorities. at pace -- one of keir's's main priorities-— at pace -- one of keir's's main riorities. ., ., ., ., priorities. how can labour guarantee that it will not _ priorities. how can labour guarantee that it will not be _ priorities. how can labour guarantee that it will not be passed _ priorities. how can labour guarantee that it will not be passed on - priorities. how can labour guarantee that it will not be passed on into - that it will not be passed on into their bills, ?

it will be the renewal energy that is cheaper. oil and i their bills,? it will be the renewall energy that is cheaper. oil and gas provision, it is already much smaller than it was in the north sea and we want to transition people into the newjobs of the future and bring down those costs as soon as we can. having a windfall tax on the oil and gas companies is the right thing to do. it is what it says, a windfall tax so as soon as their profits are back down to the levels you would expect, they windfall tax stops. it is designed to tax the excessive profits people have been making, not to stop them functioning, so it is there to help us deliver great british energy and we also have the national wealth fund, which will be investing in the industry of the future as well. the whole purpose here is to say, we know renewable energy is the energy of the future, we know people in other countries will be creating this energy and we willjust end up having to buy it if we do not create it ourselves and to take the opportunity of the newjobs that can bring. opportunity of the new “obs that can brina. . ., _, opportunity of the new “obs that can brina. . ., i, ,, , , opportunity of the new “obs that can brina. ., ., i, ,, , , ., bring. some analysis suggests that in order to reach _ bring. some analysis suggests that in order to reach those _ bring. some analysis suggests that in order to reach those 2030 - in order to reach those 2030 targets, the uk offshore wind generating capacity we need to triple in the next six years. is that feasible?

yes, i think if you listened to patrick vallance earlier in the week, he was saying the same. it is a challenge, of course it is, and we need to move at pace, but we think the benefits in terms of energy security so we are not reliant on putin and others in terms of costs, if you look at the 0br risk reports, they say if we do not change what we're doing, they will be another shock like ukraine which will affect people's bills massively, affects agility, national debt, so we have to put these systems in place to save money from these really awful shocks we have seen under this conservative government when they have not put in place the policies to protect us. have not put in place the policies to protect us— to protect us. moving on to the sub'ect to protect us. moving on to the subject of _ to protect us. moving on to the subject of emigration. - to protect us. moving on to the subject of emigration. sir - to protect us. moving on to the subject of emigration. sir keirl subject of emigration. sir keir starmer singh today the conservatives have met immigration get out of control —— subject of immigration. that the numbers are too high. is it an easy criticism to make if labour are not putting a figure on what they would reduce immigration by?
