2024 has vowed to make these olympic games the greenest games in olympic history, and bark says that it is important that athletes use their voice for change. it's extremely important because the athletes are the best ambassadors for all of these initiatives. they find the best response and they are the ones who can really convince millions of people around the world. i can give us many interviews as i want to the bbc, it doesn't have the impact when an olympic champion from today is sending this message, and we are very happy that many athletes are very active in this respect.

there will be several firsts at these olympics, but for andy murray, it will be his last. the three—time grand slam champion confirming that his career will officially come to an end after the olympics. the 37—year—old is planning to compete in the singles and doubles for team gb in paris, in what will be his fifth games. posting on x, murray said that "competing for team gb has been by far the most memorable weeks of my career and i'm extremely proud to get to do it one more time." well, the paralympics starts on the 28th august and great britain have named 11 athletes in their para—triathlon team. they include 2021 tokyo gold medallist lauren steadman who says she hasn't done anywhere near the level of training she'd have liked after contracting covid in march. the normal benchmarks i have, the normal sessions that i do to know where i'm at, i hadn't even raced until last week and that was only eight weeks before the paralympic

games, so i haven't raced the girls, i don't know where i'm at, i don't know where they're at. we have another six weeks, we've got a bit more work to do in those six weeks, but i think ijust have to have confidence and experience and that my body will come together when it is ready to come together. the premier league, professional footballer�*s association and a host of other european domestic leagues and unions have launched legal action against fifa over what they allege is abuse of a dominant position. they've accused football's world governing body of taking "unilateral decisions" on the international match calendar which they believe is "beyond saturation". the leagues and unions say fifa's conduct has "harmed the economic interests of national leagues and the welfare of players" and argue fifa's role as a regulator and competition organiser is a conflict of interest. manchester city manager pep guardiola has said influential midfielder kevin de bruyne will stay at the club this season. de bruyne had been heavily linked with a summer move to saudi arabia and the belgian, who has a year left on his contract, said last month that he would

have to consider a move because of the "incredible money on offer", but guardiola, speaking before city's first pre—season friendly against celtic in the usa, simply said, "kevin isn't leaving." and scotland striker che adams has completed a move to italian side torino on a free transfer. the 28—year—old left newly—promoted southampton at the end of last season after his contract expired. that's all from me for now. breaking news from the us. a whole variety of us media is reporting that the head of the secret service kimberly cheadle has just resigned. we saw her being questioned yesterday. this is the session, and

there was fury after the events of july the 13th, the attempted assassination attempt on donald trump and she faced a series of really hostile questions. i've watched these events and sessions in washington and congress and i've not seen a session quite like this, these are the pictures of her arriving yesterday and lawmaker after lawmaker demanding her resignation, asking her questions about the timeline, the detail and often in terms of the answers that they were getting yesterday there was generality, a lack of specifics, she was asked about the timeline and the specifics about how the 20 digital shooter came to be on that rooftop —— 28—year—old shooter. there was fury from lawmakers in the house in terms of the answers they actually heard from her. she

conceded that in terms of that operation, it was the most significant operational failure at the secret service in decades but that didn't stop her from resisting those calls in person for her to resign, but that news just emerging that the us secret service director has resigned. we wait to see the details of any letters and any correspondence and reaction there has been but inevitable in the sense of what happened onjuly has been but inevitable in the sense of what happened on july the 13th, the absolute failure is of securing that event and even the follow—up investigation, there were so many gaps in terms of the answers from the director yesterday and at one stage one of the lawmakers swearing at her and was asked to watch the language, but such was the level of frustration. the session went on for hours in terms of the grilling of

kimberly cheatle and in terms of quite what had happened, all the us agency is confirming the same story, reuters had originally reported it, the associated press, the afp, all reporting that the director of the secret service kimberly cheatle has now resigned. let's bring in our correspondent in washington. she is just getting set up and ready to talk to me after this news breaking. the director resigning less than 2a hours from the session. nomia iqbal hasjust got into hours from the session. nomia iqbal has just got into position. hours from the session. nomia iqbal hasjust got into position. ijust said, inevitable and there was no other eventuality. it said, inevitable and there was no other eventuality.— other eventuality. it was pretty remarkable _ other eventuality. it was pretty remarkable watching _ other eventuality. it was pretty remarkable watching the - other eventuality. it was pretty i remarkable watching the hearing yesterday because it was so

combative. kimberly cheatle was accused by the committee of stonewalling. remember, the calls for her to go over bipartisan. we always make this point that whenever you see any sort of bipartisanship on the hill, its was quite a rare moment, —— it is always quite a rare moment, —— it is always quite a rare moment, but she said that when she was called on to resign, she was the best person for thejob, was called on to resign, she was the best person for the job, that this investigation was still getting at what happened at donald trump's rally, and she would not stand down that was happening, but i was saying yesterday when we were covering it on air that her position was becoming increasingly untenable. for the last nine days, before she appeared at the hearing, there were constant calls for her to step down. at the republican national convention, which we attended last week, she was there and she was confronted very angrily by many republicans who were demanding to

know what happened, why did the secret service not deliver, why did they fail to protect the former president donald trump, and she kept saying that she would not be resigning and that she was coming to this hearing to explain herself, but it was always going to be a very hostile hearing, which it was. there were always calls for her to resign which weren't going to go away. this is what our partner station cps is saying, that she does plan to step down from her position as director of the us secret service —— our partners cbs. i5 of the us secret service -- our partners cbs-— of the us secret service -- our partners cbs. is it a resignation or has she effectively _ partners cbs. is it a resignation or has she effectively been _ partners cbs. is it a resignation or has she effectively been fired? - partners cbs. is it a resignation or l has she effectively been fired? good ruestion. has she effectively been fired? good question- at — has she effectively been fired? good question. at the _ has she effectively been fired? good question. at the moment, _ has she effectively been fired? (13mm question. at the moment, we understand that she plans to resign. there were calls from some members of the congressional committee for her to be fired by the president but

from what we understand, she has resigned. we will get more details as the story keeps developing but there was no doubt that the secret service was under this huge scrutiny, these questions mounting on how this attempted assassination could have happened. there was one crucial question, why was the gunman able to get onto the roof? why where there are not agents they are ready to protect it? she gave a bizarre answer, she said the secret service had an issue with sterile roofs, rooftops, and that was quite confusing and she apologised for previously saying they had a problem with flat roofs. it was quite confusing and that answer prompted a very angry response by the committee. also, the other point in the hearing, she had said that the

fbi had told the secret service that the shooter had flown a drone over the shooter had flown a drone over the rally before it happened and they were aware of that. there was another question, if you knew there was a threat to donald trump, why was a threat to donald trump, why was he allowed on stage? she could not answer all of the questions, she kept making the point that the investigation was still under way, so all of that led to this sort of inevitable moment, where we understand she has resigned. you are exactly right — understand she has resigned. you are exactly right that _ understand she has resigned. you are exactly right that some _ understand she has resigned. you are exactly right that some of _ understand she has resigned. you are exactly right that some of the - exactly right that some of the answers she gave angered lawmakers. the gaps in knowledge, some of the basic questions she was being asked days after this assassination attempt, she wasn't able to give information which frustrated and angered them even more with one lawmaker even swearing at one point

" the bleep word and accused kimberly cheatle of not being honest. the secret service was responsible for managing the overall security protocol for the rally and when she arrived at the hearing, when she arrived at the hearing, when she arrived at the hearing, when she gave the statement right out of the gate, she said that it was a significant operational failure. she made the point that the secret service exists to ultimately protect leaders of the united states, former leaders, and that they had failed, but as we are talking, she kept not answering the questions stop that's how the lawmakers felt, crucial questions, and it was very combative and got very heated. you mentioned nancy

mace, a republican, who swore at her, and there were other members from the democratic party like alexandria ocasio—cortez, a progressive democrat who was very critical of kimberly cheatle too but the criticism was across the board. kimberly cheatle was a standing firm, she said that she was not resigning and she was the best person for thejob. she resigning and she was the best person for the job. she said even resigning and she was the best person for thejob. she said even if this had happened to presidentjoe biden, she would still feel the same way, she was the best person to direct the agency but it appears that pressure has become too much and i think that's not surprising. just a final thought for now, she did acknowledge in that questioning that there had been other lapses previously. what has been said, do we know how her successor is —— do we know how her successor is —— do we know how her successor is —— do we know who her successor is or the temporary successor? such a crucial

job as we run into the campaign. we don't job as we run into the campaign. - don't know who is likely to replace her yet. we also know that this investigation into what happened is still ongoing so presumably whoever takes over from her will have to investigate that as well. as soon as we find out details, we will let you know, but we don't know who will replace her and what will happen if she has resigned or if she has been fired. ., ., fired. nomia iqbal live in washington, _ fired. nomia iqbal live in washington, thank - fired. nomia iqbal live in washington, thank you l fired. nomia iqbal live in i washington, thank you for fired. nomia iqbal live in - washington, thank you for that snapshot analysis. it is worth repeating that breaking news, all the us agencies are reporting that the us agencies are reporting that the us agencies are reporting that the us secret service director kimberly cheatle has resigned. we were watching that session only yesterday with lawmakers, both democratic and republican, absolutely grilling the director about the events ofjuly the 13th, the attempted assassination of donald trump. more reaction to that

news injust a moment. around the world and across the uk, this is bbc news.

more now on our top story, and kamala harris is hitting the campaign trail, having secured enough delegate pledges to be viewed as the democratic presidential contender. in less than four hours' time, she'll address a campaign rally in milwaukee, wisconsin — a critical swing state — where republicans and democrats will be battling it out for votes. these six states, georgia, michigan, pennsylvania, wisconsin, nevada and arizona, will likely decide who will take the white house in november. so just what do voters there think of president biden's decison to stand down, and what do they make of amala harris as a possible future leader of the country? our correspondent emma vardy has gone to arizona to find out. well, this state is really on a knife edge. it was won by donald trump in 2016

and taken byjoe biden at the last election, so it's being targeted heavily by both sides in the race to the white house. and arizona is on the border with mexico, and illegal immigration over that border has been one of the most contentious issues in this whole election. so what the voters are discussing here over their coffee and pancakes really matters. after months of hearing candidates singing the same old tunes, suddenly the records changing. a lot of people thought he'd pull out sooner than he did. i think it's best for america that he did pull out. it seems like trump's substantially ahead, especially in battleground states. could a different democratic candidate change things now? anything's possible. but in a deeply divided america, many people's views are already firmly fixed. i still think trump's going to win. i truly think that trump is a better choice, just with the economy and how things are run. what do people make of kamala harris

when it comes to the border? well, she hasn't done anything. and criminals are coming across the border and we need to close it. while there's relief among many democrat voters over biden stepping down, there isn't agreement about kamala harris automatically replacing him. my personal opinion, what has she done? what experience has she had, politically? should there be more of a contest for who should take on trump? yes, i think so, yes. for the democratic party. but it has invigorated a campaign in which a rematch betweenjoe biden and donald trump had been widely unpopular. both sides, in my opinion, i thought were just, like, "i don't really care for." i think it would be nice to have a woman in office, and especially since she's a woman of colour. the choice being served up for americans is now looking very different. but as to whether kamala harris could do any better against donald trump thanjoe biden would have, polls haven't

suggested there's much in it. but with millions now expected to pour into campaign funds, and voters are going to be seeing a lot more of her, that could change. though, for now, at least, many trump supporters don't see her as a threat. who do you think is going to win? trump. why's that? just because he's better at uniting everyone. trump was really attacking biden's age. could a new candidate make life any more difficult? after the last four weeks, no. i don't think there's any stopping him. you know, taking a bullet in the side of the head, everything else, and getting up and going to play golf the next morning. i mean, what else do you ask for? if events weren't incredible enough, nowjoe biden dropping out is another historic twist for this race in which there is still time for more surprises to come. emma vardy, bbc news, arizona. live pictures from outside of washington at the airbase, we see the helicopters because i think in

the helicopters because i think in the next few moments we are likely to see kamala harris. i was looking at the pictures on the tarmac in emma vardy�*s report on the plane is already on the tarmac, ready to take kamala harris to milwaukee in wisconsin. one of the critical swing states that will be absolutely decisive come november, and it has been a whirlwind 48 hours for the vice president given the events of sunday, givenjoe biden making the decision to stand down. the helicopters just arriving before she then goes on to milwaukee and we will cover that campaign event live here on the programme in the next few hours. researchers have found that chimpanzees in the wild take it in turns to communicate, much like humans do. the study, carried out by a team from the university

of st andrews in scotland, looked at the chimps' hand gestures and concluded that they often had rapid back—and—forth exchanges. let's speak to mael leroux, who is a lecturer in the department of animal and human behaviour at the university of rennes. welcome to the programme. very interesting, what these researchers have found. does that come as any surprise to you, that has looked at these creatures for so long at such close quarters? i these creatures for so long at such close quarters?— close quarters? i wouldn't say a surrise. close quarters? i wouldn't say a surprise- we — close quarters? i wouldn't say a surprise. we knew _ close quarters? i wouldn't say a surprise. we knew already - close quarters? i wouldn't say a surprise. we knew already that | surprise. we knew already that chimpanzees engaged in vocal turn taking, exchanging vocalisation calls, but these studies show that they can do more and also engage in gestural exchanges, and i think they are surprising us with the timing that they are showing, the timing with which they exchange gestures, and it is on average 200 ms, a time

gap between a gesture and its response, that's very close to what we humans are doing and that's quite exciting news. 50 it we humans are doing and that's quite exciting new-— exciting news. so it is back and forth 'ust exciting news. so it is back and forth just like _ exciting news. so it is back and forth just like we _ exciting news. so it is back and forth just like we have - forth just like we have conversations. what proportion of the facial expressions and hand gestures, and what proportion is vocal? i gestures, and what proportion is vocal? ., �* ., , , vocal? i don't have exact numbers but they use _ vocal? i don't have exact numbers but they use the _ vocal? i don't have exact numbers but they use the three _ vocal? i don't have exact numbers but they use the three modalities| but they use the three modalities altogether as well sometimes. it depends a bit on the context so when they are in visual contact with one another, they prefer visual munication —— vocal communication, and when they are close to each other they will engage in gestural communication.— other they will engage in gestural communication. does it tell us more about how human _ communication. does it tell us more about how human communication i about how human communication evolved? ., . , ., , .

quite as much sunshine. but ahead of that we have this nose of high—pressure extending from the azores, meaning most places will be fine and dry. earlier on today we did have a lot of cloud across south—eastern parts of england, giving some showers as well, but those have gone and as it brightens up here, it is getting warmer. we could reach 22 or 23 through the midlands, and a pleasant 22 in the central belt of scotland. could be one or two showers around, though, even by late afternoon, particularly over the pennines. those will tend to fade away during the evening, and overnight i suspect it will be dry, cloud coming and going, probably more cloud coming into western areas later on in the night. and these are the temperatures first thing on wednesday morning. so we're starting at 11 or 12. and there will be some sunshine at times on wednesday. it could be quite hazy, mind you. as we bubble up the cloud, there's the risk of one or two showers for eastern parts of england. out to the west, though, that cloud will thicken to bring a little light rain or drizzle to northern ireland and perhaps the western side of scotland, wales and the south—west.

so these areas will be a little cooler than today but towards the east and south—east in particular, those temperatures are likely to reach 25, maybe even 26, depending on the amount of sunshine. then as we head into thursday, it gets a little bit messy. we've got this tangle of weather fronts coming our way. nothing particularly well organised. the showery bursts of rain now and again, and a lot of cloud around. maybe later in the day it's western and southern areas that will turn a little wetter. but as you head into the eastern side of england and eastern scotland, it may be drier here and those temperatures will be into the low 20s on thursday. things simplify themselves by the time we get into friday, because that weather front will be moving away. it's going to be clearing away eventually from south—eastern parts of england but rain is not too far away from here for much of the day. otherwise, there will be some decent spells of sunshine but where we have stronger winds in the north—west, this is where we will see a few showers coming

into northern ireland, northern and western scotland. temperatures back to 18 in the central belt, and 22 or 23 in the south—east.
