the headlines: thousands of protesters have gathered in washington, dc, to protest forjustice and racial equality. the protest was called on the anniversary of the civil rights march on washington 1963 when martin luther king delivered his historic ‘i have a dream' speech. british scientists have been given nearly $9 million to try to find out how long immunity from coronavirus lasts. they believe that understanding how our immune system responds to the coronavirus could be one of the key factors in getting life back to normal. and one of the most powerful storms ever to hit the us, hurricane laura, has killed at least six people in louisiana. the state's governor said the storm had caused tremendous damage, but it was not as bad as originally feared. in texas, the governor said the state had dodged a bullet. organisers of illegal raves

and music events can be fined up to £10,000, under new laws in england and wales. it means that anyone responsible for gatherings of more than 30 could be fined. in london, 11,500 officers will be on duty over the bank holiday weekend, as police expect a rise in the number of illegal events. danny savage reports. a recent saturday night in manchester. in normal times, this house party with a marquee in the garden might not be a problem. but these aren't normal times. police have now banned the tenant from having anybody but themselves at home. this illegal behaviour has been happening across the area and the authorities are fed up. last weekend we had mutual aid provided by four other police forces and that will happen again this weekend was that we have 100 extra officers coming in from adjacent police forces and of course there is a

financial cost to that because we had to pay for those additional officers. and this is how the police respond. these masks on, shepherding people out into the night. dispersal is the priority, and these are areas where tighter covid restrictions are already in place. anotherfactor is that this weekend should have seen some of the biggest music festivals in the uk. this is where the leeds festival should be taking place right here, right now. that it's been cancelled and there is concern that people will go looking for unofficial, illegal, alternatives. landowners are so concerned they're paying for extra security this weekend to deter rave organisers. here is a flyer we think is linked to one weekend. the locations revealed at the last minute, word weekly spread and the event sprang up. the head of public health in lancashire is concerned about an illegal rave

there last weekend. we are right in the middle of the pandemic, and we are seeing cases rising in some of our towns. so if you are trying to organise a rave at this point in time, i think it's irresponsible and unacceptable, especially to target young people. raves have been taking place since lockdown was eased. this was somerset last month. in scotland now, people have —— police have the power to bracket gatherings of more than 15 people. this was london in july. the worriers these are high—risk super spreader events which could cause a spike in infections. danny savage, bbc news. now on bbc news: covid—19 is posing an unprecedented us election year challenge to the candidates running for president, transforming it into a virtual one. four more years! the 2020 race for the right like no other. --

white house is like no other. history has delivered us one of the most difficult moments we have ever faced was the printer virus has upended american life. before the play came in from china, we were going in a direction that we had never seen. direction that we had never seen. transformed the political conventions, launching a presidential campaign which is anything but normal. as you have seen by now, this isn't a normal convention. president trump is fighting for real action against his challenger joe biden as the nation reels from the coronavirus outbreak which has left millions unemployed, and killed more than 180,000. his only pre—existing condition was trusting donald trump stop as a national reckoning over racial injustice. i urge people to come together in a civil manner. previous conventions brought great drama and launched career the rhetoric this time depicted a country in crisis. we can and will ove 1120 m e crisis. we can and will overcome this season of darkness in america. our country can go in a horrible,

horrible direction. 0r country can go in a horrible, horrible direction. or in an even greater direction. america's voters face a stark choice: and a highly charged election. the first virtual political convention is a very strange affair, no crowds, no applause, very few media tans, no spin doctors telling you how the speech is playing here in wilmington. but in many ways, the virtual gathering is a party manager's dream. everyone has to keep the time. it is very easy to control dissent and to make the message discipline. the democrats arguing over and over again, america is facing three crises: the coronavirus, economic rollout and racial injustice. and there arguing president trump has shown to be unfit to lead. i caught up with delaware senator chris goons, long—time friend and ally ofjoe biden,

as he prepared to make his address to the convention. this is an unprecedented moment in so is an unprecedented moment in so many ways. can you generate the same excitement with a virtual convention? well, it's not quite the same thing. i am a delicate of this convention, i have been a delegate to conventions going back 30 yea rs. conventions going back 30 years. —— a delegate. and i'm really missing the balloon drop and the parties and the cheering crowd. but if it saves a few american lives, i am happy that we are doing it virtually. the joe biden personally decided we're not going to have a convention when it is the pinnacle of his political career, shows that he is committed to listening to public health experts and to protecting the health of the american people. democrats tried to make a virtue of their own convention, using the delegate rollcall to shock the diversity of the party and of america. joe biden will bring this nation together. good

evening. they must act is whether hurst, and although the keynote speaker on opening night was pre—recorded, the appealfrom the night was pre—recorded, the appeal from the former first lady who says she hates politics was none of her impact was that there may be as clear and honest as i possibly can. donald trump is the wrong president for our country. he has had more than enough time to prove he can do the job but he is clearly in over his head. he cannot meet this moment. he simply cannot be who we need him to be for us. it is what it is. if you think things cannot possibly get worse, trust me, they can and they will if we don't make a change in this election. if we have any hope of ending this chaos, we have got to vote forjoe biden like out got to vote forjoe biden like our lives depend on it. it was a message echoed by bernie

sanders, blamed by some democrats for failing to rally his supporters behind hillary clinton in 2016. there was no mistaking his urgency this time. my friends, i say to you, to everyone who supported other candidates in the primary, and to those who may have voted for donald trump in the last election. the future of our democracy is at stake. the future of our economy is at sta ke. future of our economy is at stake. the future of our planet is at stake. in most come together. to defeat donald trump and elect joe together. to defeat donald trump and electjoe biden and kamala harris as our next president and vice president. my president and vice president. my friends, the price of failure isjust my friends, the price of failure is just too great to imagine. covid-19 hit us much harder than it had to. one of the select few who have served in the oval office, former president bill clinton underlined the democrats' message that president trump

does not deserve a second term. donald trump says we are leading the world. well, we are the only major industrial economy to have its unemployment rate tripled. you have to decide whether to renew his contract or hire someone else. if you want a president who defines the job as ours a day watching tv and zapping people in social media, he's your man. in thisjob interview, the difference is stark. you know what donald trump will do with four more yea rs, trump will do with four more years, lame, bully and a little. and you know whatjoe biden will do, build back better. candidate's wife, joe biden spoke from the candidate she once taught in ——jill, telling howjoe biden lost his first wife and son. the burdens we carry a heavy, and we need someone we carry a heavy, and we need someone with strong shoulders.

i know that if we entrust this nation tojoe, he will do for yourfamily nation tojoe, he will do for your family what he did nation tojoe, he will do for yourfamily what he did or ours. bring us together and make us whole. carry us forward in ourtime of make us whole. carry us forward in our time of need. keep the promise of america for all of us. promise of america for all of us. great job! great job. republicans for biden appealed to gop voters disillusioned with president trump. with joe biden in the white house you will never doubt that he will stand with our friends and stand with our friends and stand up to adverse areas. senator mccain's widow liberated her husband was making during friendship with mr bailey despite their political differences. they would just sit and joke. it was like a comedy show sometimes to watch the two of them. the coronavirus pandemic, which has killed more than 180,000 americans and infected more

than 5.8 million was a constant theme. christina giza, whose father was a time supporter, died after contracting covid—19, she gave a raw and powerful speech. he had faith in donald trump was the eve voted for him, listen to him, believed him and his mouthpieces when they said coronavirus was under control and going to disappear. so in late may, after the stay—at—home order was lifted in arizona, my dad went to a karaoke bar with his friends. a few weeks later he was put on a ventilator and after five agonising days, he died alone in the icu with a nurse holding his hand. my dad was a healthy 65—year—old. it is only pre—existing condition was trusting donald trump —— is only pre—existing condition was trusting donald trump, and with that paid for it with his life. democratic party is still traumatised by hillary

clinton's surprise loss to donald trump in 2016, as she won nearly 3 million more votes than him lost the three key states of michigan, pennsylvania and wisconsin by fewer than 80,000 votes. so it's no surprise this we call of the keynote speakers have been urging the party faithful to vote as though their lives depend on it. and hillary clinton has turned her disappointment into a golf action. don't forget, joe and kamala can win by 3 million votes a nd kamala can win by 3 million votes and still lose. take it from me. so we need numbers overwhelming, so trump can't sneak or steal his way to victory. speaking from the museum of the american revolution in philadelphia, birthplace of us democracy. former president barack obama cast aside his natural caution and protocol to directly attack sitting resident. donald trump has grown into the job, because he can't. —— sitting president. and the consequences of that

failure are severe. 170,000 americans dead. millions of jobs, gone. while those at the top taken more than ever. our worst impulses unleased, our proud reputation around the world badly diminished. this administration has shown it will tear our democracy down if thatis will tear our democracy down if that is what it takes for them to win. so we have to get busy, building it up by pouring all our efforts into the 76 days. kamala harris is my aunt. my stepmother. my big sister! barack obama's presidency was historic, and come in a harris is the first woman of colour to bea is the first woman of colour to be a vice presidential candidate. her hope was an increasingly diverse american electorate goods eds story in her acceptance speech. —— could

see her story. i keep thinking about that woman, five feet tall, who gave birth to me at kaiser hospital in oakland, california. on that day, she probably could have never imagined that i would be standing before you now and speaking these words. i accept your nomination for vice president of the united states of america. we have a chance to change the course of history. we are all in this fight. you, me, and joe. together they are. —— together. what an awesome responsibility. the 77—year—old joe biden who tried to run for president twice before is hoping that this is his moment, as so many americans grieve so many different losses, this was his message. i have some idea how it feels to lose someone you love. i know that deep like

hold that opens up in the middle of your chest and you feel like you are being sucked into it. i know how mean and cruel and unfair life can be sometimes. the current president has cloaked american darkness from too long —— for much too long. too much anger, fear, division. here and now, i'll give you my word. if you entrust me with the presidency, i will draw on the best of us, not the worst. i will be an ally of the light, not the darkness. so it's with great and humility, except this nomination for president of the united states of america. joe biden is presenting himself as a unifying figure. a protector and comforter who will draw on his 50 years in public life to solve the nation's many woes. he has the backing of his

pa rty‘s different he has the backing of his party's different wings for now as they are desperate to oust donald trump. portraying the current election is nothing but a battle for the soul of america, joe biden is trying to win over the voters who are wa ry win over the voters who are wary of the frenetic trump presidency. branding is all—important to donald trump. the real estate mogul who became a reality tv star and used that as a springboard to the presidency. donald trump hotel here in washington as a regular haunt for those wishing to get in the president's good books and stay there. and just as his turbulent first term was marked by the near daily tv appearances, so marked by the near daily tv appearances, so the republican national convention is a chance for the president to dominate the airwaves in his quest for a second term. law and order was a rallying cry at the republican convention. the death of george floyd and may lead to a wave of mostly peaceful protests across america, but some of the

clashes turned violent. in wisconsin this week, jacob blake was shot by police and amid the demonstrations and counter protests, two people we re counter protests, two people were killed. ron christie, who worked in the white house president george w bush says president george w bush says president trump will try to appeal to voters who are worried by the unrest. certainly the president has really looked at law and order. we look back to 1968 when richard nixon won with a silent majority of appealing to people for law and order. i think the president is looking at a trifecta of things. he is looking to rebound with the economy, looking to contain the pandemic and then of course as isaid pandemic and then of course as i said the law and order, trying to bring more social cohesion to the demonstrations we have seen. republicans also talked up how their convention would simultaneously feature a

hopeful uplifting message, but on the opening morning, president trump accused democrats of encouraging voter fraud because they want people to be able to vote by mail and the election. what they are doing is using covid—19 to steal an election. they are using covid—19 to defraud the american people, all of our people, of a fair and free election. from the very beginning, democrats, the media and the world health organization got coronavirus wrong. the first night featured a congratulatory video praising the handling of the coronavirus outbreak. president donald trump... the top back republican lawmaker was the keynote speaker, as republicans try to show white voters put off by mr trump's polarising rhetoric on race, the president has african—american support. there are millions of families just like mine all across this

nation, full of potential, seeking to live the american dream. and i'm here tonight to tell you that supporting the republican ticket gives you the best chance of making that dream a reality. much of the convention was devoted to ominous warnings about what a biden administration would do to america. take this from mark and patricia mccluskey who were filmed brandishing guns to defend their home as racial justice protesters marched by. no matter where you live, your family will not be safe in the radical democrats' america. and the culture wars were front and centre as kimberly guilfoyle, girlfriend of the president's old est girlfriend of the president's oldest son, stated that a biden presidency would threaten americans way of life. they wa nt americans way of life. they want to destroy this country and everything that we have fought for and hold dear. they wa nt fought for and hold dear. they want to steal your liberty, your freedom, they want to control what you see and think

and believe that so they can control how you live. republican strategists hope that will motivate the president's base of white supporters to turn out and even paul and some people who didn't vote for him last time. trump for four more years! it's how donald trump jr framed the choice facing voters. people of faith are under attack. you are not allowed to go to church, but mass chaos in the streets gets a pass. it's almost like the selection is shaping up to be church, work, and school versus rioting, looting and vandalism. is the week progressed, republicans try to soften trump's hard edged image, having family members and ordinary americans pay tribute to him. my name is jason joyce tribute to him. my name is jasonjoyce and tribute to him. my name is jason joyce and i'm tribute to him. my name is jasonjoyce and i'm an eighth generation lobster fishermen from main. as long as trump as president, fishing families like mine will have a voice.

co ntroversially, like mine will have a voice. controversially, the white house itself was the backdrop for night two. of latent use of government property for a political campaign. there was even a live naturalisation ceremony is the president, who wa nts to ceremony is the president, who wants to build a war with mexico, welcomed new americans, trying to draw a distinction between illegal immigrants and legal ones. you are now citizens of the united states. first lady melania trump made one of her rare forays into the spotlight the trump campaign believes she can reach out to the female voters disenchanted with the president. in contrast to her husband, she expressed sympathy for those who have lost loved ones to coronavirus. i know many people are anxious and some feel helpless. i want you to know, you are not alone. my you to know, you are not alone. my husband's administration will not stop fighting until there is an effective treatment or vaccine available to everyone. donald will not rest

until he has done all he can to ta ke until he has done all he can to take care of everyone impacted by this terrible pandemic. melania trump made this appeal amid the social unrest.|j melania trump made this appeal amid the social unrest. i urge people to come together in a civil manner so that we can work and live up to our standard american ideals. i also ask people to stop the violence and looting being done in the name ofjustice, and never make assumptions based on the colour of a person's skin. republicans are trying to reframe the election around civic unrest, not the cause of it, as the tensions in wisconsin on the wake of the latest shooting worsened, the vice president amplified the message. the virus must stop. weather in minneapolis,

portland, or kenosha. too many heroes have died defending our freedom to see americans strike each other down. we will have law and order on the streets of this country. the south lawn of the white house was the backdrop for the finale of the republican convention. the crowds flooding the administration's own coronavirus guidelines as the president's daughter tried to soften her father's rough edges. whether you agree with him or not, you always know where he stands. i recognise that my dad's communication style is not to everyone's taste and i know that his tweets can feel a bit unfiltered, but the results? the results speak for themselves. president trump use themselves. president trump use the building known as the people house as a prop for his campaign witha people house as a prop for his campaign with a dig at his opponent's. the fact is, i'm

here. what's the name of that building? applause but they will say it differently stopping the fact is, we are here, and they are not. the president defended his handling of the pandemic. in recent months, our nation and the entire planet has been struck bya entire planet has been struck by a new and powerful invisible enemy. like those brave americans before us, we are meeting this challenge. we are delivering life—saving therapies and will produce a vaccine before the end of the year or maybe even sooner. we will defeat the virus and the pandemic and emerge stronger

than ever before. the crowded south lawn was the closest mr trump has got to one of his trademark rallies in months. he used the platform to hammer home the republican attack. make no mistake, if you give power to joe make no mistake, if you give power tojoe biden, make no mistake, if you give power to joe biden, the make no mistake, if you give power tojoe biden, the radical left will defund police departments all across america. they will pass federal legislation to reduce law—enforcement nationwide. they make every city look like democrat run portland, oregon. no—one will be safe and biden's america. donald trump's once hostile takeover of the party is complete. it's been remade and his image and now he is asking americans rehire him. the first votes will be cast by mail in september. the people are about to have their say. the convention season is over, the general election is less

than 70 days. what sort of a fight do you predict? a very, very protracted one and it is almost can be like knife fighting in the trenches. the biden people are going to vote for biden, the coalition they have amassed, people of colour, ethnicity, sexual orientation, they already know they are voting for biden. the hard—core republicans, the trump base, they know they are voting for trump so the question is, who can appeal to the middle? the independence? there are more registered independents here in the united states than say they are republicans or democrats, how do you get to them and get them in yourcamp? how do you get to them and get them in your camp? america is more deeply divided and parted in the never stopping the battle now is for those swing voters. who is to decide if donald trump has earned a second term or ofjoe biden's unifying message is more appealing? after these unconventional conventions, the stage is set for a most consequential election.

hello there. you could see the rain coming on friday, but it was very difficult to get out of the way. this weekend, though, the weather is set to change. for a start, it's going to be a much drier weekend. however, it's not going to be very warm at all. some particularly cold nights, and we're going to start with some strong winds as well. a northerly wind as our area of low pressure takes most of the rain away towards the south—east and gets pushed away slowly by that high pressure coming in from the west. by the time we get to the morning, there still could be a few showers down the eastern side of england, and there's the threat of cloud coming back in off the north sea to bring some rain in during the afternoon. elsewhere, some spells of sunshine. there will be a few showers notably across northern parts of scotland. there will be a northerly wind as well. it's always going to be stronger where we're more likely to have that rain.

could be gusting 50 mph or so. it will make it feel cold, of course. temperatures typically 13 to 17 degrees, a touch warmer than that, maybe, towards the south of wales and the southwest of england. many places will turn dry during the evening. that wetter weather gets pushed into the east midlands towards the south—east of england and east anglia. that'll keep the temperatures up here, but elsewhere with clear skies, lighter winds, we could see temperatures even as low as two or three degrees in some rural areas. so a chilly start to sunday. by this stage, the winds won't be as strong. there'll be some cloud across east anglia and the south—east. any early showers should move away, keep the odd shower coming into the northwest of scotland, even one or two for northern ireland. otherwise, some sunshine at times, more cloud around during the afternoon. those temperatures not changing much, but it won't feel as cold as it's not going to be as windy. that's because that area of high pressure is pushing across the country. eventually, it'll be followed by this weather front to bring some rain into northern ireland. that's a very slow process. for the late summer bank holiday last year, it was the hottest ever.

temperatures reached 33 degrees in the sunshine. this time around, it could be the coldest bank holiday monday ever, with 18 the expected high in london. again, the winds will be light. they're starting to turn to more of a southerly direction. sunny start, cold start, but more cloud filling in through the day. probably dryjust about everywhere. some rain into northern ireland later on in the day. but those temperatures again struggling, typically only 16 or 17.

hello and welcome to bbc news if you're watching in the uk or around the world. we start in the united states, where thousands of people have taken part in a huge civil rights rally in washington to demand racial justice and an end to police brutality. it's being held in the same place and exactly 57 years after the reverend martin luther king junior made his famous ‘i have a dream' speech. it was planned as a response

to the death of george floyd
