of illegal migrants. less than five months from now and we're going, and i'll tell you what — we have to change the system. we have to straighten out what's going on in these courts. we got a rigged deal going, this whole country, and we've got to do it. and those appellate courts have to step up and straighten things out, or we're not going to have a country any longer. but we're going to win the great state of arizona, and we're going to tell crooked joe biden, "you're fired — you're doing a lousy job, the worstjob — the worst president in history. joe, you fired!" our correspondent emma vardy, was at that rally in phoenix and gave us this update there were several thousand people queuing outside this building in extreme temperatures. and infact, over1,000 people didn't get in. some people were taken to hospital by emergency services. but for the people who did make it inside this event, the energy is very high, the volume is very high. they're clearly also relishing the opportunity to show what they think of trump's recent criminal conviction. there are people here wearing his police mugshot on t—shirts, holding his mugshot on placards, saying "never surrender". and, as you say, when trump took to the stage, he didn't waste much time in hitting out at the judge in new york and calling it a rigged trial. now, of course, arizona, a key battleground state — it was won by donald trump in 2016, narrowly turned blue for the democrats byjoe biden in 2020 — so both sides know this is a must—win state, being particularly seen as a must—win state for those who want to get the keys back to the white house. but, of course, away from here, it's the undecided swing voters who are likely to make all the difference as to which way this state goes. some i talk to this morning say, "look, we don't feel enthusiastic about either candidate this time round." it's not a very popular rematch betweenjoe biden against donald trump, according...suggesting — the polls are suggesting. and those i spoke to said they voted in many elections their whole lives but don't even know if they're going to go out and vote. so yet more evidence that perhaps it is which side gets its vote out most successfully that is really going to be the deciding factor of this election. i'm nowjoined byjill abramson — who's an author, academic and the former executive editor of the new york times. if swing voters are now centrestage and a lack of enthusiasm is the issue, i guess centrestage and a lack of enthusiasm is the issue, i guess both centrestage and a lack of enthusiasm is the issue, i guess both candidates centrestage and a lack of enthusiasm is the issue, i guess both candidates need centrestage and a lack of enthusiasm is the issue, i guess both candidates need to be

in the us and this was donald trump talking to his base, feeding his base the same red meat he always does, i am talking about rigged judicial proceedings and rigged judicial proceedings and rigged elections and saying that we are losing the country. we didn't hear one word new and what got attention in the speech was the use of curse words and explosives —— expletives, and this was not a message for swing voters, it was emotive for trump voters. you said he'd mention the rigged judicial proceedings. do you think donald trump could be successful in his appeal? i am loath to predict _

little attention. it was the 80th anniversary of d—day and president biden gave a very good speech about ukraine are on the role of democracy in the world and what world war ii was fought over and

programme. _ well, its five months to the us election but just four weeks until people go to the polls here in the uk. and later today the first of the bbc�*s prime—time election debates takes place — a seven—way contest between the biggest parties in great britain. it follows the debate on tuesday between the two main party leaders — the prime minister rishi sunak and the labour party's keir starmer. nick eardley from bbc verify has been looking at the participants and some of the issues they'll be debating. yes. it's a big one tonight. seven parties taking part. a quick reminder who they are conservatives, labour, lib dems, snp, greens, reform. lots for us to fact check and scrutinise tonight. but ijust wanted to remind you of some of the contentious claims that have dominated the week so far and why you should be aware of them. this was the most contentious claim from tuesday's debate the prime minister's claim that under labour tax will go up £2,000. that statement, though, is misleading. the 2000 firstly, is over four years. it's about £500 a year. it's also based on political assumptions. some of them are dubious. labour have said they won't put up income tax, national insurance or vat, but labour have a dubious claim of their own. this one that there's a £71 billion gap in the conservative spending plans. the problem is that's based on the assumption that the conservatives will do things that they've said they won't, like scrapping national insurance in the next few years. so if either of these claims tonight, it is fair to be sceptical. now we don't know for sure what is going to come up this evening, but the cost of living is an issue the parties have been talking about a lot on the campaign trail. we've all felt the impact of rising prices. but here's a piece of context worth knowing for tonight. living standards will be lower at the end of this parliament than they were at the start of this parliament. that is not normal. another important piece of context. the economy has started growing a bit in recent months. the prime minister is keen to talk about that. but overall, in the past couple of years, it's been pretty flat and because of that flat growth experts, some of them anyway, are warning that we're likely to see a spending squeeze for whoever becomes the next government. so there's a question tonight — will the parties explain what they're going to do about that and where they're going to prioritise money? we also heard a lot in the last debate on tuesday about this — record levels of immigration. tonight, we'll actually have more opinions on that issue. nigel farage's reform party wants net migration to be zero. other parties taking part tonight, like the snp, say that immigration is a good thing. but these are the numbers you need to know as context — on legal immigration on legal immigration first. net migration. that's the difference between the number of people coming into the country and the number of people leaving. it was a record high in 2022. as you can see, it started to come down a bit and is expected to fall further. that's legal migration. illegal immigration, small boats crossings. they reached a record high in 2022. they were down a third or so in 2023. but look at that down there. that's 2024 so far. and so far, that is higher than it's ever been at this stage of the year. we'll hear tonight what the party solutions might be. now there is plenty of other stuff that could come up. we'll be here tonight with the bbc�*s team of fact checkers looking over what said. and we'll have a lot more tonight and into tomorrow. and a reminderfor viewers in the uk that we'll be building up to the bbc�*s election debate — featuring representatives from the seven biggest parties in great britain — all day today on bbc news. and then of course the the main event is on bbc one, bbc iplayer and with signing on the bbc news channel from 7.30 tomorrow evening. more officers are today

to return from a hike on wednesday lunchtime. simonjones has the latest. in the scorching greek sunshine, the searches are continuing — both on land and from the air — trying to find out what has

wednesday lunchtime when he decided to go for a walk. a sighting was reported at pedi. he then failed to return. he didn't have his phone with him. what can science tell us about getting a better night's sleep? some people think of sleep as a luxury... michael mosley, who's 67, has been on our tv screens for more than two decades, talking about health and science. apparently, this is the easiest and most reliable way to find out. a presenter known for getting stuck in. i've got this list of the things that i'm allowed on my new diet. he would often focus on diet and exercise. he's a regular on the one show — last night's programme opened with the presenters sharing the feelings of many viewers... lots of us concerned to hear that our friend michael mosley has gone missing whilst on holiday in greece, and our thoughts are very much with his wife clare and the rest of his family at this worrying time. we hope for more positive news. ..and his disappearance is the front page story on the daily mail, where he's a columnist. the search is proving to be challenging, covering rugged terrain. the police, firefighters, a sniffer dog and volunteers are involved. all the rescue teams of the island are looking to find him. with drones, they are going to all the islands. as concerns for michael mosley grow, police say more officers willjoin the search today, as an extreme heat warning for the island is issued. simon jones, bbc news. let's get some of the day's other news now the un children's fund says more than 30 children were among the victims of an attack on a village in central sudan on wednesday. the assault — in which over 100 people died — has been blamed on the paramilitary rapid support forces. the british tech tycoon, mike lynch, has been cleared of fraud charges in the us over the eleven billion dollar sale of his software firm to the computer group hewlett—packa rd. a jury in san francisco found him not guilty on all counts. we'll have more on this in business later in the programme a british woman who says she's the inspiration for the stalker character in the hit netflix show baby reindeer has sued the company for more than $170 million. fiona harvey's lawsuit says the show�*s claim that it is a true story was "the biggest lie in television history" the white house is calling on israel, to publicly release the names of the 20 to 30 hamas fighters, it says it was targetting, in an airstrike on a school being used as a shelter in gaza. the head of the un agency for palestinian refugees, says the attack was "horrific," and more than 35 people are thought to have died. israel says it was a "precision strike," aimed at the fighters operating from inside the school, in the nuseirat refugee camp. while israel does frequently release names of those it's targetting, it's rare for america to push for such transparency. with me is mohammed taha from bbc arabic america's questioning of the attack is unusual and underlines their

say climate change could threaten the food supply of antarctic whales. sea ice is declining at an alarming rate — and researchers say humpback whales hold clues about the effect that's having on the marine ecosystem. 0ur science correspondent victoria gilljoined a research mission, led by the wildlife charity wwf, which is carrying out health checks on humpbacks whales around the antarctic peninsula. delving into the lives of antarctica's giants. we're with a team of wildlife scientists studying humpback whales up close. that is pretty amazing, to be able to see them under the water! the researchers have special permits to check the health of whales in this part of antarctica. the climate is shifting in the antarctic peninsula faster than anywhere else in antarctica. scientists want to know what impact rising temperatures and other pressures — like tourism and fishing — have on wildlife here. 0h! and they have a surprising way of finding that out. so is that a weapon? no, it's not a weapon, it's a tool. that tool allows natalia to take whale tissue biopsies. a tube on the end of each arrow takes just a tiny nick... ..out of each animal's body. the sample is three centimetre, something like that, for an animal, you know 16 metres long. so it's essentially a mosquito bite. well, it clearly didn't bother them very much because they're hanging around the boat. analysing this tissue can reveal if a female humpback is pregnant. in years that we have low seas, then the following year, you have lower pregnancy rates, and that's as good as it gets in, like, you know, getting to know the environment and getting to know the effects of all these conservation threats on the animals. this is what the whales and many other animals here feed on — antarctic krill. swarms of them thrive here because they eat algae that lives
