the first came in the triathlon mixed relay. alex yee and georgia taylor—brown added to their individual silvers. they were joined byjonny brownlee and jessica learmonth. then, in the pool, great britain claimed another gold in the mixed axioom medley. so where does all this leave the medal table? well, great britain remain sixth, with eight gold medals and 27 in total. up at the top is china with 20 golds and 44 overall. meanwhile, the american gymnast simone biles has pulled out of two more olympic events as she deals with mental health issues. on the track, the leading nigerian sprinter blessing okagbare has failed a drugs test and is out of the games. she won her heat in the 100m on friday and had been due to run in the semifinals later. let's take you now live to tokyo and speak to the bbc�*s sarah mulkerins, who is following all the action.

a great day for the mixed events. we have the mixed triathlon relay, two men and two women in the team. we know that team gb had a very strong triathlon history and pedigree, the two individual silver medals, as you say. they were highly fancied coming into it but they still have to pull off that victory. when alex yee was on the final leg to take it over taken for a period on the bike, but he held strong i was evil —— able to open up estates on the run and print them all the way to the finish line to wind that gold medal. a lovely moment forjonny brownlee, who won bronze back in london in 2012, silver in rio in 2016, and finally got an olympic gold medal. a few

short hours later in the pool, what an amazing olympics team gb are having and swimming. adam peaty started it all off and they haven't been able to stop winning metal stents. they had a fantastic run with a world record in the mixed medley, where you caterfor different strokes, backstroke, breaststroke, freestyle, butterfly. two men and two women again. really nice to see the teams being able to do that. a lot of tactical matchups, who you put on each leg, and it was really interesting on the final leg with anna hopkin on freestyle, we knew that caeleb dressel was on that for the usa and he has been setting world records at this meet. she was able to hold him off to wind the gold medal. you can see with the chairs and celebrations after what short amount to the four of them to be able to weather together. what mixed events are bringing to the

olympic games, as well, is shown. let's switch elsewhere. she's a four—time olympic champion, but this may be the games simone biles is remembered for most? absolutely. over the last week she has opened up a big conversation in sport around how athletes cope with mental health, the pressures they are under. you country in olympic games, you're one shot in four year to compete at the very top and there is an awful lot of pressure that goes along with that. when she pulled out of the team event and was so honest afterwards about it, she started a conversation. we've been getting updates every day since and how she is going. she pulled out of the team event a couple of days later and didn't take part in the all—around event. we have been waiting for an update on the individualfinals, there waiting for an update on the individual finals, there are four she could take part in. she has

confirmed she will not take part in the vaults and also in the bars, they were due to take place on sunday. there are two more that will take place on monday and tuesday and we are yet to hear on that. team usa say they are continuing to monitor that. there has already been controversy surrounding drugs on the track? yes, the nigerian sprinter blessing okagbare has been sent from the games after testing positive in and out of competition test that took place on the 19th ofjuly. she tastes —— tested positive for human growth hormone. she was in action last night in the heats for the 100 metres for women. she qualified through to the semifinals and she was due to take part in that in the next hour or so, but after testing positive the athletics integrity unit informed her of the positive test result and have removed her from the games. the games are over

for her and she will now go through the anti—doping process. she had been quite critical a couple of days ago when ten athletes from nigeria had been not allowed to take part in the games because they haven't completed enough of the pre—competition tests. she was quite vocal about her federation making sure that they hadn't put enough processes in place to ensure that all the athletes could get here with fulfilling all of those tests. so a couple of bad days for nigeria in the athletics. we have a busy night on the track to come. who is looking good ahead of the women's 100m final later? the �*s 100 metres has been built to be one of the events of the games. there is so much talent in it. we had to heat yesterday, the track was really fast. they are also wearing

these super spikes which we may be talking about in recent days. shelly—ann fraser—pryce is 3a years old, she has set a personal best this year. she is running super fast. she looked really comfortable in the heats. she is a two—time alaba champion, she could be the first to win three medals —— three gold medals. dina asher—smith is the home hope for team gb. she looked very comfortable in her heat. the defending champion is from jamaica, elaine thompson. i don't think anybody is really able to call how this might go. we will have the three semifinals and the next hour or so, and then they will have the final a couple of hours later. it will be the top two and two semifinals at the two fastest losers. it is very hard to call that

yes, pam. losers. it is very hard to call that yes. pam-— losers. it is very hard to call that es, pam. ., ~ ., yes, pam. thank you, sarah, we will catch u- yes, pam. thank you, sarah, we will catch up with — yes, pam. thank you, sarah, we will catch up with you — yes, pam. thank you, sarah, we will catch up with you later. _ thank you, sarah, we will catch up with you later. let's get some reaction to that gold medal in the triathlon relay. i'm joined now by andy salmon, ceo of british triathlon. thanks forjoining us on bbc news. you must be overjoyed. goad thanks forjoining us on bbc news. you must be overjoyed. you must be over'oyed. good morning. not a lot of you must be overjoyed. good morning. not a lot of sleep _ you must be overjoyed. good morning. not a lot of sleep overnight! _ you must be overjoyed. good morning. not a lot of sleep overnight! we - not a lot of sleep overnight! we woke up this morning feeling thrilled. a fantastic night last night and we are so delighted for the team. flan night and we are so delighted for the team. ., , ., , . night and we are so delighted for the team. ., i. , ., ., , the team. can you explain how this really works? _ the team. can you explain how this really works? it _ the team. can you explain how this really works? it is _ the team. can you explain how this really works? it is a _ the team. can you explain how this really works? it is a brand-new - really works? it is a brand-new event, really works? it is a brand-new event. never — really works? it is a brand-new event, never been _ really works? it is a brand-new event, never been seen - really works? it is a brand-new event, never been seen at - really works? it is a brand-new event, never been seen at the | event, never been seen at the olympics before. the initial response is that it has been a huge success. we have two men, two women. a woman goes first, does the swim, bike, and a run and then tags to the next man, who does another triathlon, and so on and so on. it

georgia a lead, she increased the lead towards the end of the run, she handed over to alex. what about his composure for a 23—year—old, to have vincent louise passed you on the first lap, but to have the composure to know that he could pull away on the run, and that is exactly what he did. all four of the transitions were exceptionally good. you put all of those things together, and a fantastic preparation these guys have stopped in britain, because of the national lottery, we are able to invest in support these athletes and perhaps ways that athletes in other countries are not supported. we are very grateful for that. i countries are not supported. we are very grateful for that.— very grateful for that. i know you don't want _ very grateful for that. i know you don't want to _ very grateful for that. i know you don't want to single _ very grateful for that. i know you don't want to single anyone - very grateful for that. i know you don't want to single anyone out, | very grateful for that. i know you . don't want to single anyone out, but let's talk aboutjonny brownlee, means that triumphant games farewell for him. his first gold in his third olympics. he said earlier this year he is new challenge. can you sum up

a spike in cases in recent days has prompted an extension of the capital's state of emergency. it has also been expanded to cover other parts of the country. tokyo olympics organisers have reported 21 new games—related covid—19 cases. no athletes are affected by the latest cases, but this takes the total games—linked number of infections sincejuly1 to 241. health officials in england are urging anyone who has not had their coronavirus jab yet to get vaccinated this weekend. all adults have been able to book a first dose since mid—june, but latest figures show that nearly a third of young adults still haven't had one. walk—in centres opening over the coming days include one at burnley football club and a circus in halifax. we've seen a great response to the vaccine programme so far, with nearly nine out of ten people having had theirfirstjob and over seven out of ten now fully immunised, but we're going to pull out all the stops this weekend.

we know that getting vaccine sites popped up at those places where people are going to be is really important, so whether you are with the jugglers in the circus in halifax, whether you are with the football fans in burnley or with the runners and riders at the racecourse in goodwood, if you haven't had your jab, this is the weekend to get it. israel has accused iran of being behind an attack on an oil tanker in which two crew members were killed, including a british national. the mv mercer street was off the coast of oman in the arabian sea when the incident occurred on thursday. israeli sources say the tanker was attacked by a drone. the briton, and a romanian national who was also killed, have not yet been named. the usjustice department says tax returns belonging to the former president donald trump must be handed over to congress. the decision reverses a previous ruling. officials now say lawmakers have legitimate reasons for asking to see the documents.

our north america correspondent david willis reports. donald trump has fought hard to prevent the release of his tax returns. this isjust a continuation of the most hideous witch—hunt in the history of our country. this latest ruling could mark the beginning of the end of his ferocious effort to keep those documents out of the public eye. then treasury secretary steven mnuchin's refusal to comply with a subpoena back in 2019 prompted a two—year battle for documents including asset, income and tax payment data on the part of the democrat—led house ways and means committee, which is investigating potential conflicts of interest on the part of the former president and the possibility of foreign interference. now, in a 39—page ruling, the usjustice department has reversed a ruling made when trump still in office and has ordered the treasury to release six years'

worth trump tax returns — a move hailed by the house speaker, nancy pelosi, who called access to the documents: every president since richard nixon has disclosed details of their tax returns, the one exception being donald trump. he claimed before he was elected that his records were under ordered by the authorities, a process that was apparently audit by the authorities, a process that was apparently still under way by the time he left office. republicans say the entire issue is politically motivated. they have denounced thejustice department decision and donald trump is widely expected to challenge it in court, meaning that if those highly anticipated documents are to be made public it could still be many, many months away.

david willis, bbc news, los angeles. afghan military officials say they have managed to push back taliban militants from the southern city of lashkar gah in helmand province after they advanced close to the city centre on friday. it is the second provincial capital the armed group has entered in recent days. it comes after afghan security forces, aided by american air strikes, recaptured a district around the airport in the western city of herat. with us—led foreign forces nearing a complete withdrawal of troops, the taliban have made swift territorial gains over the last two months. the england cricketer ben stokes has been praised after it was announced he is taking an indefinite break from the sport with immediate effect. he has withdrawn from england's squad for the five—test series against india to prioritise his mental wellbeing and rest a finger injury. in a tweet, the england and wales cricket board said he had shown tremendous courage to open up about his feelings.

the news about ben stokes follows confirmation that simone biles has withdrawn from a further two events at the olympics, having previously said she needed to focus on her mental health. we can discuss the impact of mental health on elite athletes further. i'm joined now by professor steve peters, sports psychiatrist and author of �*the chimp paradox'. he is best known for his work with british cycling. thank you forjoining us on bbc news. huge respect for simone biles, realising she needs to focus on our own mental health, and ben stokes, too. , ., , , own mental health, and ben stokes, too. , , too. yes, absolutely. if you compare it to a physical— too. yes, absolutely. if you compare it to a physical illness, _ too. yes, absolutely. if you compare it to a physical illness, they - too. yes, absolutely. if you compare it to a physical illness, they would i it to a physical illness, they would make a decision not to do it. if you look at the mental apparatus that we have, if that is not functioning properly then you are likely to underperform and likely do yourself

permanent home. that is a terrible situation to find families and in the 21st—century. we are calling for the 21st—century. we are calling for the government to work with us, as they have worked with us throughout they have worked with us throughout the pandemic, to allow us to build 100,000 homes that actually are truly for rent at affordable prices. the right to buy system, well it has worked for many, it has worked for all and a0 years on from the start of that we now have a massive shortfall of affordable council homes and that is a real issue. given the context of the pandemic, how feasible is it to build 100,000 new homes, and the finances that would require?— new homes, and the finances that would require? well, if we take what government — would require? well, if we take what government keeps _ would require? well, if we take what government keeps talking _ would require? well, if we take what government keeps talking about - would require? well, if we take whatl government keeps talking about when it comes to finances, it says we are

in the same place we were in after the war. after the war they had to builders —— biggest house—building programme, linked with the nhs being formed and their welfare benefit system working for the whole country, so actually i don't think it is aboutjust the pandemic, it is that about the long a0—year lack of replenishing the stock that local government has lost. remember, we couldn't put any money back into the housing stock. we have asked the government to retain any that you get sold, and at the moment they do. we are asking the government to make sure that the benefit system is adequate. it is ridiculous that in 2019 twice as much money was paid out in housing benefit plan was given to local government to build more homes. given to local government to build more homes-_ more homes. councils in england sent more homes. councils in england spent more _

more homes. councils in england spent more than _ more homes. councils in england spent more than 140 _ more homes. councils in england spent more than 140 million - more homes. councils in england spent more than 140 million and| spent more than 1a0 million and placing homeless households and bed—and—breakfast in 2019—20. is that about using that financing more wisely, as well? you that about using that financing more wisely. as well?— wisely, as well? you can only place --eole in wisely, as well? you can only place people in the _ wisely, as well? you can only place people in the stock— wisely, as well? you can only place people in the stock that _ wisely, as well? you can only place people in the stock that is - wisely, as well? you can only place people in the stock that is there. i people in the stock that is there. it is about replenishing what we have lost. if i take the amount of stock even in my own area, we have lost two thirds of the council housing that we had back in the early 1980s. that means i can't deliver the homes that people need to rent. if you take that across the whole country, that is why we have 1.5 million families, the size of birmingham give ortake, 1.5 million families, the size of birmingham give or take, in temporary accommodation. we are forced to go to the market. the market can charge —— charge four or five times the rent that the council would charge. that is not sustainable. it does not make business sense to keep paying the landlord on what we need to do is

build the homes.— build the homes. thank you for “oininu build the homes. thank you for joining us- _ russia has reported almost 800 deaths from coronavirus for a third consecutive day. 792 people died in the past 2a hours. the country is battling a surge in infections, blamed on the infectious delta variant. australia's third largest city, brisbane, is to go into lockdown again in another attempt to contain the spread of the delta variant of coronavirus. the deputy premier of queensland said millions of residents in brisbane, and several other areas, would be ordered to stay at home for three days. a survey by roadside assistance company rac has found seven in ten british motorists believe the speed limit should be lower in wet weather. currently the speed limit is 70mph on motorways at all times, but with nearly 250 people killed on the country's roads during bad weather, many feel there should be greater efforts to force motorists to slow down. rod dennis is from the rac.

the uk telecommunications industry hopes a satellite that has gone into orbit will help maintain its global leadership in the sector. a quarter of the world's big telecoms spacecraft are manufactured in britain and the new quantum platform is billed as the market's next—generation product. quantum was launched on an ariane rocket from french guiana last night. here's our science correspondentjonathan amos. another rocket climbs skyward to bolster a sector that europe, and the uk in particular, has come to dominate — the business of telecommunications satellites. there are hundreds of these spacecraft overhead, bouncing tv, phone calls, broadband and other data services around the planet. but the new satellite going into orbit, called quantum, represents a big step

forward in technology. while traditional telecom spacecraft are configured before launch to do very specific tasks, quantum has been built for flexibility. it is the sector's first fully reprogrammable spacecraft. it is able to rapidly change the coverage, bandwidth, power and frequency of its signals. one of its uses will be for disaster response, providing emergency communications to the teams that are sent to help people in places hit by catastrophic floods or earthquakes. quantum's manufacturers in the uk, that is airbus and surrey satellite technology ltd, will incorporate the prototype's technology into their future spacecraft, hoping to maintain their world leading status in what has become a highly competitive field. let's get more on the olympics from

tokyo. you have had a busy morning, mike. yes, an excellent morning 1a gp. it has been a golden saturday at the tokyo olympics. teamwork has been key in the new olympic events, and triathlon and into the pool. the triathlon will be golden for great britain. it's the mixed medley relay, great britain win the gold by miles. for all the individual brilliance, in the tokyo today it was teamwork that triumphed. super saturday had barely begun, but team gb was already looking at four new olympic champions in this, the inaugural triathlon really. triathlon relay. jessica learmonth led the way for britain. then the turn ofjonny brownlee. individual bronze in london, silver in rio, this his final olympic race, a last chance to complete the set.

georgia taylor—brown had given britain a 21 seconds advantage and, although alex yee was dramatically caught for a moment, when he came to the finish, he and gb were in a class of their own. he will win the gold. four new british olympic champions before breakfast. forjonny brownlee, gold at last. the olympics? i've completed it. i've been waiting for that one. yeah, it feels absolutely amazing. third olympics and to finally walk away with olympic gold, and we did everything we possibly could. whilst over in the pool, team gb have surpassed expectations. now a moment for the team's finest to come together. the mixed medley relay, another new olympic event. in the company of the finest swimmers on earth, britain have already proved they can excel. here they were doing it again. kathleen dawson gave way to the peerless adam peaty. he did what he always seems to do. before james guy powered britain into the narrowest of leads. and here was anna hopkin

in the final leg. great britain are going to win their fourth gold in the swimming pool. one word that has changed the whole team is belief. we've got champions who believe we can win, champions who believe and get world records and if you've got one belief, you build everything around that. two team relays, two olympic team titles, another golden day for team gb. emma wilson has taken windsurfing bronze on her olympic debut. she was already guaranteed a medal going into the final after winning four of her 12 races and she crossed the finish line in second place. but with cumulative scores counting, that gave her bronze behind china's lu yunxiu and the rio champion, charline picon of france. lauren price made sure of at least a bronze medal, after a dominant display in her middleweight quarterfinal. she won 5—0 against panama's athena bylon, to set up a meeting with her great rival nouchka fontijn of the netherlands on friday.

price is the number one seed, having won gold at the 2018
