of north carolina, seemingly unfazed by the torrent of bad headlines his disjointed debate performance had generated. crowd: joe! joe! - folks... i don't walk as easy as i used to. i don't speak as smoothly as i used to. i don't debate as well as i used to. but i know what i do know. i know how to tell the truth! crowd: yeah! he seemed for all the world like a new man, reading from the teleprompter with a passion that had been all too absent the night before. i know, like millions of americans know, when you get knocked down, you get back up. it was a far cry from the rasping and rambling performance on the debate stage that was all too often painful to watch. everything we have to do with, uh... look... if... we finally beat medicare. it's left his party in a state of crisis. yet, despite rumblings about replacing their candidate, publicly, at least, democrats are circling the wagons. referring to his own lacklustre performance in a presidential debate in 2012, joe biden�*s former boss barack obama tweeted, "bad debate nights happen. "trust me, i know. "but this election is still a choice between someone who has fought "for ordinary folks his entire life and someone who only "cares about himself. despite being just three years younger thanjoe biden, donald trump has consistently condemned his rival as too old to be re—elected. but addressing supporters in virginia, he said the question was less one of age and more one of competence. the question every voter should be asking themselves today is not whetherjoe biden can survive a 90—minute debate performance, but whether america can survive four more years of crooked joe biden in the white house. crowd boos and the calls forjoe biden to pull out of the presidential race are growing. this the headline in an editorial in the new york times, which goes on to declare, mr biden is not the man he was four years ago. i don't think so! the word from the biden camp is that their candidate has no intention whatsoever of pulling out of the race, but much may depend on how he fares going forward and what the opinion polls make of his debate performance. david willis, bbc news, los angeles. there is plenty more reaction and analysis on the bbc news website, you can see it there on your screen. do take a look on what this means that the democrats going forward. let's turn our attention to the uk. the reform uk leader, nigel farage, has insisted that secret filming that caught one of the party's campaigners using racist language to describe the prime minister was a "set—up". the video provoked condemnation from other party leaders. in a special edition of the bbc show question time, mr farage suggested the video could have been arranged to smear his party. our political correspondent leila nathoo reports. the leader of reform uk, nigel farage. the final weekend of the election campaign and for one party leader, difficult questions are piling up. what is it about you and your party that attracts racists and extremists, whether you say you want them or not? i've done more to drive the far right out of british politics than anybody else alive. i took on the bnp just over a decade ago. i said to their voters, "if this is a protest vote, "but you don't support their racist agenda, don't vote "for them, vote for me." and we destroyed them. nigel farage was challenged last night over homophobic and racist remarks made by reform uk canvassers, secretly recorded by channel 4 news. one campaigner implied gay people were paedophiles, and another suggested army recruits should shoot at people crossing the channel in small boats, and used a racist insult to describe the prime minister. mr farage insisted that man was an "actor", and described the channel 4 report as a deliberate attempt to smear his party. this was a comedy act, but it was designed to hurt us and sadly — sadly — some people believe it. let me promise you... so who do you think would have done this, nigel farage? i want nothing to do with people like him and he has nothing to do with us. he's somebody who turned up. we didn't know who he was, and by sheer coincidence, he happened to get teamed up with channel 4. elsewhere, nigel farage was questioned about his party's manifesto and how he would pay for his promises. there's a lot of stuff in your manifesto, but how do you actually plan to pay for all this stuff? we can comfortably save £30 billion a year by growing up and being sensible, and recognising if we want carbon—free energy — reliable, not intermittent — carbon—free energy, the only way to go is small modular nuclear reactors. also fielding questions on stage last night was someone whose views could not be more different — adrian ramsay, the co—leader of the green party. i think we all know that we need |to step up action on the climate| crisis, both to adapt to the changes that are already happening, - but to avoid the runaway climate change that will affect us - all dreadfully if we don't get to grips with this. i and he defended proposing to raise some taxes in his party's manifesto. we're talking about £5 extra a week for someone earning £55,000. - now, what would that get you? at the moment, people can't access an nhs dentist, - and if you can afford to do so, you might be forking out- for a private dentist. well, how much does that cost you over a year? - how much does it cost you over a year to pay extortionate - train ticket prices because we're not - investing in our railways? or to have to heat your home - and see your bills going up and up every month, because we've got the leakiest homes in europe . and we haven't insulated them? so we're setting out a different vision, sonia, for where yes, . we ask those earning a little bit more to pay a little bit more, . including the multi—millionaires and billionaires, but it's- about a different type of society. for all parties, the journey to polling day is nearly over. leila nathoo, bbc news. the first of the main party leaders to be out campaigning on saturday was labour's sir keir starmer. he was at an event in aldershot, in south—east england, meeting military veterans to mark armed forces day. while he was there, he was asked about the rise of what some would consider to be extreme views in political campaigning. well, i am concerned about populism and nationalism and i think in a time where in our country and across the world there are increasing challenges of every variety, the like of which we haven't seen until recent years, it is very important that we have a progressive answer to those challenges. we are a progressive party, we hope that we can win the election and form a progressive government, a government that always says country first, party second, but also rises to the challenges both in this country and across europe. 0ur correspondent harry farley was at the event with the labour leader. he sent us this summary. keir starmer and his was talking about a government of service for those who serve. and interestingly, i was going through the labour release this morning and i counted 11 times the party used the word serve or service, making a very clear pitch for that military vote. and as much as what the party is saying today, it's where they're saying it. i'm in aldershot, aldershot football club, another lower league football club that the labour party and the labour leader in particular has made a bit of a habit of visiting over the last few weeks of this campaign. the conservatives have won this seat every time, every election for the last 100 years. but now labour think they have got a real chance of winning this seat. they took control of the council in may and they think that this will go... this seat will go right down to the wire. the message from sir keir starmer, which we've been hearing over the last week or so, is if you want change, you have to go and vote for it. and i think that tells you something about the mood in the labour party campaign. it tells you that they are nervous and there's a hint of concern that all the talk of the polls, which we've been talking about over the last few weeks, that show that big gap for leader, they are worried that people will take that to mean it's a foregone conclusion, that the result is already known. and they want to make sure that over these next few days, it's not so much about winning the air war, getting your message across, changing minds. it is about persuading and reminding your supporters to go to the polls and vote. and that will be the focus that i think we can very much expect from the labour party throughout this weekend and into next week. this is a list of the candidates standing in the aldershot constituency. you can read more about the seat on our special election section on our website or via the bbc app. iran's interior ministry has confirmed that a run—off presidential election will be held on friday, after none of the candidates in the snap poll secured a majority. the reformist masoud pezeshkian, a heart surgeon, won the largest number of votes. one of his hardline rivals, saeed jalili, came second, after taking an early lead. the election was called after the death of ultra—conservative president ebrahim raisi in a helicopter crash last month. the four candidates were all vetted by an influential committee of clerics before they could stand. turnout was about a0%, according to an interior ministry count, the lowest on record since the 1979 revolution, raising questions about the legitimacy of iran's system of government. siavash ardalan from the bbc persian service told me more about the election. this is the lowest turnout we've seen since the 1979 revolution, 43%. i mean, that's pretty low, not even counting those spoiled ballots which might take the real turnout down to the 30s. this is just unprecedented, especially given the fact that the supreme leader had come out a few days before the election saying that, "we want people to turn out because if they turn out, "then that will prove that the people are still loyal "to the system and the system is legitimate, whereas a low turnout "is bad news for us." so, they have a run—off vote. do you think now that pezeshkian is leading in this first round, do you think people will turn out in the second, in the run—off vote? it really depends, it really depends. so, the society is very polarised now. on one hand we have these people turned away from the elections altogether, you know, giving a very powerful message to the system, "we don't want you, we don't want the clerical "establishment any more, we want more like a secular, "liberal—minded democracy," and then you have those conservative votes, those regime loyalists who have also become radicalised in their own way, choosing a very hardline candidate as opposed to a centre—right candidate, mohammad baqer qalibaf, who used to be the capital's mayor, current speaker of parliament, he sort of supports relations with the west and removing sanctions but at the same time he also takes a very hardline stance on other issues as well. so whether the 13% of people who voted for him, whether they will choose to vote for a far—right candidate or they will choose a moderate pro—reform candidate, and also those election boycotters, whether they will see if there is any difference between these two candidates, because any talk of differences between candidates in a clerical system, for them, is seditious. well, let's just talk about that, because ultimately it's the supreme leader who has the say on everything, isn't it? explain how much influence the president can have. the president in iran's political system is an administrator. all final matters is decided by the supreme leader on foreign policy and many other issues, the general direction of the country, but it does matter who the president is. you have the former president, hassan rouhani, who made a deal with the west, we had the nuclear deal which the americans decided to withdraw from, otherwise maybe iran would have, you know, become more integrated and their national system would have all sanctions removed, and you also had a very hardline president who brought about three un security council resolutions upon itself. so on terms of day—to—day life of iranians, economically, their lifestyle, it does make a difference who the president is. but itjust turns that out a lot of people don't think the reformers have achieved enough, that they have stood up to the hardliners as much as the people expected them to. is it possible to say anything about the female vote? we don't have a breakdown now of how many people from different segments of society voted for who and what percentage were females, what percentage were the minorities, religious minorities, ethnic minorities, people around the border, in the centre, we don't have that breakdown yet. once we do, we will have a better picture, but obviously disillusion and dissatisfaction runs very high among the female population as well, because you know the women, life, freedom protests two years ago against mandatory hijabs was led by females in iran. dozens of firefighters, police and mountain rangers have joined what authorities had hoped would be a "massive search" on tenerife for missing british teenagerjay slater. they had also called for experienced volunteers to come and help, but by 10am, fewer than a dozen members of the public had arrived at the meeting point. the 19—year—old was last seen on the 17th ofjune in a national park on a remote part of the spanish island. police confirmed that today's search would go over much of the same ground as previous ones, but that it would be more intensive and detailed, making use of the extra personnel. let's speak to our correspondent, nick garnett, who's in tenerife. just talk us through what is going on right now. just talk us through what is going on right "ow-— on right now. 0k, it is the same search areas _ on right now. 0k, it is the same search areas that _ on right now. 0k, it is the same search areas that have - on right now. 0k, it is the same search areas that have been - on right now. 0k, it is the same - search areas that have been searched before but they are working further down the valleys and ravines, in areas they have not been able to get to fully before in large numbers. there are about 30 people in total, put into little groups of five or six, and they are going around the search area, so at the moment they searched this valley here extensively over the last ten days, but now because they have more people working today, they are able to go further down into the ravine and are working in an area that is right at the end of the focal lens at the moment. it is a very long way away and incredibly hard work to do it. the question is how or whyjay would have gone that far, but there is that theory that if somebody is not all there is nothing in the place you have searched, you have to move on a little further and try and search there and that is what they are doing. they hope they will find something, some clue as to say what happened to jay, where he went to, why and what has happened to him since. 50 why and what has happened to him since, . . ., why and what has happened to him since. . . ., , ., since. so excruciating, they wait for the family, _ since. so excruciating, they wait for the family, isn't _ since. so excruciating, they wait for the family, isn't it? - for the family, isn't it? absolutely. they flew out almost as soon as they heard he was missing and they have been here ever since, trying to help but not knowing really what to do. they can only give assistance to each other and be in touch with the authorities. the authorities haven't said very much in terms of opening to the newspapers all the broadcast media. however, today there was a short news conference in which they confirmed two men who jay visited on the night he disappeared who were british are not suspected of any wrongdoing and are not part of this investigation. they firmly believe that one way or anotherjay went down into these ravines and they don't know if he left, they are looking to make sure and they are going through every single section of the ravines to make sure there is nothing that that they have missed so far. . «a nothing that that they have missed so far. . , nothing that that they have missed so far. ., , . ., so far. ok, thanks very much for that undate- _ some flights to and from the republic of ireland are being disrupted on saturday, because of strike action by aer lingus pilots. the strike is part of an ongoing dispute over pay. it began at 5am and will last for eight hours. the airline says there are "a number of options" for passengers affected. a court has acquitted all 28 people charged with money laundering in connection with the panama papers scandal. the verdict concludes a trial in panama that began in april. among those exonerated werejurgen mossack and the now deceased ramon fonseca, founders of the defunct law firm mossack fonseca, who were at the centre of the scandal. the panama papers were a trove of 11 million documents leaked to journalists in 2016, revealing the offshore financial secrets of world leaders and other public figures. a temporary us pier, designed to deliver aid to gaza, has once again been removed because of high seas. these are newly—released images of the pier in operation this month, showing aid being off—loaded from a ship. it's the third time since it became operational in mid—may that weather conditions have forced the pier to be detached from the gaza coast. distributing the aid to gaza's population has also been problematic, because of israeli military operations nearby. as a result, aid is piling up at a depot onshore. a pentagon spokesperson has acknowledged that the marshalling area is almost full. if there's not enough room on the marshalling yard, then it doesn't make sense to put our men and women out there when there's nothing to move. there is still room. i don't want to give the impression that it is at capacity. it is certainly full. but we do need to see that marshalling yard open up to allow for aid groups to continue that distribution so that we can get more aid in as we get it from cyprus. wildfires continue to burn in several parts of the us, including this blaze at boulder view in arizona. it only broke out on thursday, but has been burning out of control, and has already consumed nearly 13 square kilometres of land — that's more than 3,000 acres. the knockout stages of the euros begin this afternoon. the first game sees champions italy up against one of this summer's dark horses, switzerland. tonight, the hosts germany play denmark. let's go live to dortmund and speak to our sports correspondentjohn watson. it is the exciting stage, isn't it? it is the exciting stage, isn't it? i suppose i talk with trepidation because i know there are penalties coming back to talk us through what we are expecting. first, italy, switzerland, italy reigning champions but not perhaps looking like it particularly, is that fair enough? i like it particularly, is that fair enou~h? ~ ., , ., ., enough? i think that is fair to say. italy came — enough? i think that is fair to say. italy came close _ enough? i think that is fair to say. italy came close to _ enough? i think that is fair to say. italy came close to going - enough? i think that is fair to say. italy came close to going out - enough? i think that is fair to say. italy came close to going out at i enough? i think that is fair to say. | italy came close to going out at the group stage, it was only a late goal against croatia which really saved their fortunes against croatia which really saved theirfortunes in against croatia which really saved their fortunes in this tournament for the holders, but they obviously have great pedigree in this tournamen
