speech of her life. the body of the british tech entrepreneur, mike lynch, has been recovered, after his yacht sank off the coast of sicily. the search continues for his teenage daughter, hannah. russians marked a patriotic holiday — flag day — to much pomp and ceremony, despite ukraine continuing to launch attacks on the country's territory. a breakthrough in alzheimer's treatment — but it won't automatically be available in the uk —— the regulator says the benefits are too small to justify the cost. hello, it's 7am here in singapore and 6pm in chicago where kamala harris is getting ready for one of the biggest

moments of her political career. in the next few hours she will take centre stage and give the keynote address it's a big moment this weeks democratic party convention has all been building to this. this is the scene live — where the us vice president will formally accept the democratic nomination for president, hoping to become the first female president in the country's nearly 250—year—history. but she won't be alone on stage, there will also be speeches from michigan governor gretchen whitmer and north carolina governor roy cooper, who both represent swing states. it's the fourth and final day of the convention in chicago. delegates have been addressed by prominent members of the party's past, like former president barack obama — and its future like vice presidential nominee tim walz. eric swalwell is a california congressman and friend of harris — he said the coming hours would be a chance for her to introduce herself to the american people and gave us some hints of what to expect from the speech. i've known kamala for 20 years. we both got our start in the same prosecutor's office. she's tough, she's real,

she's ready, but also, what we're all starting to see is she knows how to have fun. she's a serious person, but she doesn't take herself too serious. and she knows what matters. and i think you're going to see in the speech tonight, you know, really focusing on working people and making sure that if you work hard, you do better for yourself and dream biggerfor your kids. so before vice president harris�*s introduces herself to america — lets look at who she is and her rise to the highest levels of american politics. 59—year—old harris is one of two children. her mother, shyamala gopalan, was born in india and received a doctorate in endocrinology. herfather, was born injamaica and became an economics professor at stanford university. in 2003 she became the district attorney of san francisco. but her career in politics took off in 2017, when she was elected to the us senate representing california. in 2020 ms harris unsuccessfully ran for president, eventually becoming joe biden�*s running mate. as vice president she launched a nationwide �*fight for our freedoms tour�* — highlighting the harm caused by abortion bans.

she also has cast the most tie—breaking records by a us vice president in the history of the senate — helping pass the inflation reduction act and the american rescue plan. ms harris was tasked by president biden with tackling migration at the us southern border. she led diplomatic efforts to address the root causes of migration from three central american countries. she secured the democratic presidential nomination shortly afterjoe biden ended his bid injuly and endorsed her. meanwhile, michael tyler — communications director for the harris—walz campaign — stessed the need to look beyond this evenings events to the campaign ahead. take a listen. to the campaign ahead. we're to the campaign ahead. excited about the energy, enthusiasm we're excited about the energy, enthusiasm of the course of the first month of this campaign. 0urfocus is when first month of this campaign. our focus is when we leave chicago and headed to the general election here for the final few general election here for the finalfew months, again making sure we're converting all of this energy, all this enthusiasm into action on the

ground. enthusiasm into action on the ground. as we mentioned ms harris was tasked by with tackling migration at the us southern border. republicans have been critical of her work on this issue. to prove that point donald trump has been visiting swing state arizona, near to where stretches of the border wall were built. trump says some parts of the wall were not put up after he left office, which he claims led to a wave of illegal immigration under the biden and harris administration. listen to this. we had a borders are, who was, a borders, she loved the title but she didn't want to do work because she's lazy and probably more importantly than being lazy, she wants to have an open border and you say, "who would want to have an open border where terminals can pour into our country? " and all you have to do is walk up there if you have the courage to do it and go to that open section, stand there for a little while, you'll be running back your very quickly. i'm joined now by linda robinson senior fellow for women and foreign policy, council on foreign relations.

thank you so much forjoining me. wejust heard thank you so much forjoining me. we just heard from thank you so much forjoining me. wejust heard from donald trump attacking harris over her work on migration into the united states without what do you make of the way that the trump and his campaign have been attacking harris?- trump and his campaign have been attacking harris? well, i think he started _ been attacking harris? well, i think he started off— been attacking harris? well, i think he started off with - been attacking harris? well, i think he started off with a - been attacking harris? well, i think he started off with a lot| think he started off with a lot of sexist and racist comments and the slurred that she was at d el and the slurred that she was at d ei candidate for that diversity equity and inclusion when she's a very successful biracial daughter of immigrants, a real american success story. i think on the policy side the immigration system has been broken for that as many point out it's really congress that needs to fix it. more portly, i think people are not aware of how broad her foreign—policy experience has been this last three and half years. also on the senate intelligence committee when she was in the senate, she had been to age orfour times, she met

with dolinsky six times for the she has really —— zelensky. she's led the national space council, she's been the foremost architect of safe and responsible policies on artificial intelligence. so i just mention a few of these things so people understand that she is ready to handle that she is ready to handle that tough foreign policy portfolio and serve as commander—in—chief for the which is one of the things, polls show there are persistent doubts about women's ability to doubts about women's ability to do national security and crisis management. luckily, there are early polls showing that people do have confidence in her as a crisis manager. isaac is partly because she's a very skilled speaker, prosecutor, attorney general, she does have to marshal facts general, she does have to marshalfacts and general, she does have to marshal facts and evidence and make arguments. frankly, looking forward to the debates i think she's going to wipe the floor with him. it i think she's going to wipe the floor with him.— floor with him. it will be interesting _ floor with him. it will be interesting to _ floor with him. it will be interesting to see - floor with him. it will be interesting to see how. floor with him. it will be l interesting to see how the floor with him. it will be - interesting to see how the two styles will contrast against

each other. the harris campaign has been quick to draw the contrast between the prosecutor and the convicted felon on that front. i want to get your thoughts on something else with it the first female president, thinking when hillary clinton was running back in 2016, harris is not taken the same approach on the cover has she? no, she definitely is not running as a woman president. she will be a president who happens to be a woman. also we do need to know, we've come a long way from 2016 when hillary clinton was the first candidate, they were six in 2020 and the democratic party, one was kamala harris. and now with nikki haley as the last challenger standing against donald trump and the republican contest. she was quite sharp and effective on the debate floor as well. i think it's important to note about her pictures to help the working and middle class and to bring the country to gather —— pitches for the pain to be an

inclusive leader. using all the republicans appearing as part of the speakers these last few days. i think also she's reframed the reproductive rights debate skilfully about freedom. that means personal freedoms for people to live their personal lives as they wish. which is kind of a core value that will appeal to the independents that are the very key vote she needs to get. together with the law and order background and her toughness. i think she's pretty well—positioned to be able to win. i don't want to minimise the challenges for the us as many country still has a lot of characteristics put the but the fact that also, jd i has 3 characteristics put the but the fact that also, jd i has a lot of lingering gender bias. 0ur many country still has a lot of lingering gender bias. 0ur political system is very tough political system is very tough to win in. we're the only to win in. we're the only presidential election with an presidential election with an indirect vote through the indirect vote through the electoral college that favours electoral college that favours a small, rural red states she a small, rural red states she has her work cut out for her. has her work cut out for her. i'm quite a bit more optimistic i'm quite a bit more optimistic given her personal given her personal characteristics put the but the characteristics put the but the

fact that also, jd vance fact that also, jd vance is a huge liability. he's basically come out and declared a war on women. and making comments like childless cat ladies that shouldn't have an equal vote in this country. well, 46% of americans are single. i think he's really going to turn out to be a real albatross for donald trump's campaign. thank ou for donald trump's campaign. thank you for your— donald trump's campaign. thank you for your insight. _ donald trump's campaign. thank you for your insight. linda - you for your insight. linda robertson. the yacht company that built the vessel which sank

0ur correspondent mark lowen reports from sicily. it was to celebrate his acquittal on fraud charges, his rehabilitation in public opinion. mike lynch bringing together family and colleagues on his luxury yacht. he never made it off alive. today, a source close to the family said he died when the bayesian sank on monday, and that the final body, still missing, is believed to be his 18—year—old daughter, hannah. friends paid tribute to a giant of the tech industry. i knew him at the beginning of the internet. mike was a standout character and intellectually understood the implications of the internet when, frankly, most people over here were scrabbling around. you don't get to the scale of achievement that he's done without a very hard headed, tough determination, but obviously an intellect that is really extraordinary. the family ofjonathan bloomer, the chairman of morgan stanley, and his wifejudy, have now released a statement. describing them as "incredible

people," and an "inspiration to many," after confirming the couple were among the other six people now known to have died. with the last body to recover, the divers went down for a fourth day this morning, scouring the wreckage on the seabed. a painstaking search with a painfulaim. the bayesian is still largely intact, 50m underwater. the bodies found so far are believed to have been in the cabins sleeping when the storm hit. mr lynch is likely to have been in the master suite. his wife survived. the guests were next door — and then the ten crew. all of them were rescued, apart from the chef, ricardo thomas. the company that built the bayesian showing off its portfolio of other luxury yachts online, insists it was utterly safe. and despite the violent storms that night caught on cctv drenching the coast where the bayesian sat, the company's head says for it to have gone down so quickly, human error must be to blame.

tranlation: it had i absolutely no problem. it was a model for many other ships because it was so stable. water must have flooded in, maybe through a side door left open. without that, even in such a storm it would have been unsinkable. the weather alerts clearly show that the storm would arrive at 4:00am. the captain should have closed every hatch, raised anchor, sailed into the wind and lowered the keel. then everyone could have gone back to sleep and the crews would have happily continued. and so the end may be in sight for the divers' work, perhaps bringing loved ones closer to that term they may never reach — closure. canada's labour minister says he has ordered a binding arbitration process, to end a strike which has brought much of the country's rail network to a standstill.

two companies had locked out more than nine thousand workers on thursday after talks with the teamster union broke down. the trains carry billions of dollars of goods and raw material from canada to the us each month. labour minister steve mackinnon said he was confident services would be restored, but would not commit to a timetable. fundamentally we're asking the board to direct a resumption of activities and a return to work at the real ways. we're asking them to begin the process of binding arbitration and extend collective agreements that are currently in place. the indian prime minister, narendra modi, is due to visit kyiv on friday — a month after he visited russia. india imports russian crude oil, despite calls from western countries for sanctions against the trade, and mr modi will be the first international leader to visit ukraine since it launched its cross—border incursion into russia's kursk region. the fighting continues in ukraine's eastern donbas region, the ukrainian military says the situation around pokrovsk remains tense —

as russian forces continue to try to push forward. more civilian evacuations from the city have been taking place. and in russia — a ferry has sunk near the black sea port of kavkaz, after reports it was hit by a ukrainian missile. it's reported to have been carrying a cargo of fuel. russians marked a patriotic holiday, flag day, on thursday to much pomp and ceremony, despite ukraine continuing to launch attacks on russia territory — including the ongoing incursion into russia's kursk region. there are signs of growing alarm about young russian conscripts allegedly being sent to that region despite promises they wouldn't be. 0ur russia editor steve rosenberg reports from moscow. in moscow, they celebrated russian flag day. but you probably guessed that. a day for pride, for patriotism, for believing

in russia's strength, even now when ukrainian troops are seizing russian territory. this man isn't following news of the incursion on tv. most russians, he tells me, don't want to know. they just get on with their lives. but this lady said she is terrified by what is happening. "russia will win," she says "and nothing will be left of ukraine." for more than two weeks now the russian military has been struggling to regain control in kursk region. this is embarrassing for the kremlin. but president putin used flag day to praise russian soldiers, past and present, for defending the motherland. president putin has a difficult balancing act here. 0n the one hand, ukrainian soldiers still fighting inside russia. that is a huge challenge to his authority. he will be desperate

to restore control. 0n the other hand, he doesn't want the russian public to panic about this and so the authorities here create the image almost as business as normal, everything under control. but russians don't seem to feel that. there is unease, apprehension. especially now that young conscripts are reportedly being sent to kursk region. grigori runs an ngo outside russia. it helps russian men escape conscription. translation: we've been getting more calls from young _ men or their relatives because they are being deployed to kursk region. there's been a big reaction to this in russia. contract soldiers who have decided to fight are one thing. conscripts are completely different, people understand they don't go voluntarily. this russian commander dismissed parents�* concern. "if you think your conscript sons shouldn't have to defend the country," he said,

"why does our country need you or your children?" the kremlin says that with the tricolor, russia has become a great power. but it is war in ukraine is bringing greater certainty. steve rosenberg, bbc news, moscow. around the world and across the uk. this is bbc news.

india has denied being the cause of severe floods that have hit bangladesh. delhi's eastern neighbour has seen a worsening situation in six districts in recent days. torrential rains are affecting almost two million people. some organisations have blamed india, suggesting the opening of a dam upstream on the gumti river is to blame. but a statement from india's foreign ministry said that was "factually not correct".

ajudge in romania has ruled that the social media influencer and self—described misogynist, andrew tate, must be kept under house arrest, while prosecutors investigate new allegations against him and his brother, tristan. romania's serious crime agency has alleged that they were part of a criminal group which groomed women, forced them to make explicit video content and kept the proceeds. one of the brothers who is not named is accused of having sex with a fifteen year old girl. they've strongly denied the allegations. lecanemab is a breakthrough drug that can slow down alzheimer's disease and it's been approved for use by the uk medicines regulator. it helps to clear the build—up of a toxic protein in the brain, and slows cognitive decline. but the drug won't be available on the nhs in england because it's said to be too expensive. here's our medical editor fergus walsh. that's fine. all right. yeah. mavis is a rarity, one ofjust a few alzheimer's patients in the uk who are receiving

lecanemab. she's been having an infusion every fortnight for several years. this was november 2022. mavis was part of a trial which showed the drug delayed progression of early alzheimer's by around four to six months. do you remember we used to watch the ducks in there? her husband is grateful for the extra time. it's enabled mavis to keep her personality. i mean, she's still our mavis. she always was bright and cheery and she still is. we've had some wonderful years since you came on this drug, haven't we? yeah. and some great times. yeah. and i'm grateful for it, too. my, goodness, you know, it's making a difference to your life, isn't it? now i heard... yes? ..that you had a big coffee morning this morning? - 0h, did i? do you remember that? no, i don't. lecanemab is not a wonder drug. mavis' short term memory

remains badly affected. it works by clearing a rogue protein which builds up in the brains of alzheimer's patients. i've calculated lecanemab is likely to cost around £20,000 a year privately, but administering the drug and brain scans will probably double that which the health assessment body, nice says does not represent value for money. you hold that for me, please? right. and i'll use this on your left, 0k? there are dozens of similar drugs going through clinical trials. alzheimer's charities want the nhs to get ready for this new era of treatment. this is a defining moment for alzheimer's disease and gives us real hope for the future. but we have some big challenges ahead because the key to getting access to this treatment, or any potential future treatment, will be getting an early and accurate diagnosis. and we're nowhere near that at the moment.

lecanemab can cause brain swelling and bleeding, so patients need careful monitoring. despite the risks and its modest benefits, many alzheimer's researchers regard lecanemab as a turning point because it shows this dreaded disease has its weaknesses and better drugs will follow. fergus walsh, bbc news. let's take a look at some other stories in the headlines. bangladesh's interim government says it's revoked the diplomatic passport of the ousted leader, sheikh hasina. the interior ministry said the decision also applied to former ministers of her government, and to mps no longer in post. the longtime bangladeshi prime minister resigned earlier this month and fled to india after student—led protests forced her from power. the indonesian parliament has dropped controversial plans to change the election laws, as protests take place in cities across the country. police in the capitaljakarta clashed with demonstrators, angered by what they saw as an attempt to strengthen president

joko widodo's influence. thailand has announced its first confirmed case of a new, potentially deadlier strain of mpox — the first in asia, and second outside of africa. according to thailand's department of disease control, the infected 66—year—old european man arrived in bangkok from an unnamed african country on 1a august. let's get more now from the democratic national convention in chicago. influencers on social media are playing a key role in the election campaign. the democrats are embracing those with loyal online followings to spread their message — as ione wells reports. these conventions always get loads of media attention, but this year something is different. y'all what's up. everybody? this is day one of the dnc. you see how i do my makeup for work. i there is a special box here just for influencers and content creators. more than 200 of them have been given press passes for the first time. the idea is they can share what's going on here with millions of young people on tiktok, on instagram, especially people who might not

be getting their news from newspapers or other broadcast media. today, i really want to talk to you guys about why i am so excited to make kamala harris our next president. this really isjust giving my audience. that's used to me talking about the news of the day, a really behind the scenes look at democracy in action. my followers, who are a lot of gen 2, are really galvanised and ready to vote. and so i'm helping usher that information to the next generation. i've done outfit of the days. this is day three - outfit, and it's really nice to bring people - in who normally wouldn't engage in politics. some people don't even know what the dnc is i and they're like, oh, that's a great outfit. j why are you here? they've got access to i a special lounge here. they've got help from the party connecting them to key political figures. it's a very tactical strategy from the democratic party because, for example, they may not have to be as impartial as some traditional media outlets might be. they may not also be as likely to ask difficult questions of the presidential nominee if they run openly pro kamala harris account. so that's why it's been

controversial among some in the media. most people get their information on social media, so why not support that? this was a very smart decision. i would have to say from the dnc to engage people where they are. we're on the internet, we're on social media. these kind of influencers are going to be absolutely key in rallying support and information for young people. this might seem like a tall tale — but a zoo has named their two new giraffes — after asking people for suggestions. the two half—siblings were both born this summer in berlin. lots of animal enthusiasts suggested names for the adorable duo — but after careful consideration — they eventually went for berti and emily. but don't worry if you missed out on the chance to make a suggestion, another pregnant giraffe there is expected to give birth in september. so get those names in now! that's all for now — stay with bbc news. hello there. storm lillian will dominate the first half of friday, but it's moving at quite a pace

and so by lunchtime the worst of the weather will have cleared away. however, before then, a spell of heavy rain, but more importantly, some gales, unseasonably strong winds for this time of year and still many people on holiday. the strongest of the winds likely to be to the scottish borders down into north wales and the north midlands, a zone of winds gusting widely 50,60 miles an hour, maybe even stronger in one or two places up to 75 miles an hour. that front will ease its way steadily eastwards, so already we can see the first signs of an improving picture into the northwest of scotland. this is 6:00 friday morning. a spell of very heavy rain, maybe even some thunder clearing the scottish borders first thing and the gusts of wind widely 50, close to 60 miles an hour at time. a rash of sharp showers across northern england. a trail of cloud and nuisance rain once again through the midlands and southeast england that will ease away. the low pressure moves over to scandinavia and then

a quieter afternoon, not quite as windy. still blustery winds, driving in some scattered showers to the far north and west 1a to 18 degrees. the high in scotland and northern ireland 23 degrees. the high, perhaps in southeast england, but as we move out of friday into the early hours of saturday morning, there could be a pulse of very wet weather moving its way into south east and eastern england. now, we haven't seen that much in the way of rain this august, so that will bring a spell of much needed rain for the gardens out there, but it will linger for some time on saturday, only slowly easing away into the afternoon, strong as the winds further north and west. here we'll see a frequent rash of showers on and off throughout the day. top temperatures generally a little bit below par for this time of year. now from sunday and into bank holiday monday, the azores high will tend to build back in across central and southern england. one or two weather fronts toppling across that high.

so once again, we're back to showers or longer spells of rain into the far north and west. hopefully a little drier and eventually a little bit warmer further south.

we'll focus on a speech by us federal reserve bossjerome

powell as the final night of the democratic national convention gets underway. plus — what do people really think about online dating? a survey of thousands of americans has some clues. hello and welcome to business today. i'm steve lai. let's begin in the united states, where the democratic national convention is in its final day in chicago. from recent speeches, we now have clearer ideas on the potential economic policies of the two candidates trump and harris. but across the country, from the campaign trail to wall street, there is focus on federal reserve chairman jerome powell's address at the mountain resort of jackson hole. the bbc�*s michelle fleury has more. inafew in a few hoursjerome powell of the chair of the us federal reserve america's central bank will deliver his most important speech of the year. when he spoke two years ago at this gathering, which has become known as the divorce for central bankers, the
