hello, i'm christian fraser. you're watching the context on bbc news. former home secretary priti patel has been eliminated from the conservative party leadership contest, while robertjenrick comes top of the ballot. we will get it to some of that shortly. let's pause, though, and go check on the sport with olly foster. many thanks indeed, christian. jack draper is on court at the us open. the british number one is in his first grand slam quarterfinal, and he made a flying start against the australian tenth seed alex de minaur. he squandered a number of set points, but still took the first 6—3. one worry is that he had to call the physio early in the second set for what looked to be a groin problem. there was a break—up in the

second, and di minaur has broken back and leads 5—4. so, di minaur looks like he's going to level the di minaur looks like he's going to level the coral di minaur looks like he's going to level the coral about di minaur looks like he's going to level the coral about —— quarterfinal. karolina muchova has made it through to the semi—finals in the women's draw. the czech took the first set 6—1 against the brazilian beatriz haddad maia, but had to deal with illness throughout the second set, having to take a number of bathroom breaks. she said she didn't want to go into too many details. let's put it lightly. —— lightly. she still took the second 6—4 to reach the last four in new york for the second year running. nations league matches are fast approaching for the home nations. england have given their first news conference since the players gathered at st george's park ahead of the matches against republic of ireland in dublin on saturday then finland at wembley next tuesday night. they'll be lee carsley�*s first games in charge since he was given the interim head coach role as the fa continue their search for a permanent replacement for gareth southgate. angel gomes is one of those

in line for a debut after playing for carsley in the under—21s. he's a very fair coach, he's very honest, he's direct in his approach. and he's very close to the squad, and i think it helps as a player when a coach takes interest in a player — notjust takes interest in a player — not just on the takes interest in a player — notjust on the pitch, but off the dash off the england have made one change for the final test against sri lanka that starts on friday at the oval. leicestershire pace bowlerjosh hull comes in for matthew potts. at 20 years old, when he makes his debut, hull will become the third youngest seamer to play for england after sam curran and ben hollioake. he's 67" and took five wickets against sri lanka last month playing for england lions. both sam and ben made their debut at 19. after this test series, england will play australia

in eight white—ball matches. scotland have started their t20 series against them, with a heavy defeat. they set australia a target of 155 to win in edinburgh, and travis head set off on a one—man mission to reach that with a blistering display of batting. he reached 50 offjust 17 balls, the joint fastest by an australian in t20s. he was eventually out for 80, hitting five sixes and i2 boundaries. marcus stoinis cleared the boundary for the winning runs in the tenth over, the tourists cruising to a seven—wicket victory. the sides will meet at the grange again on friday and saturday. australia's kaden groves won stage 17 of the vuelta y espana from arnuero to santander. in a dash to the line, groves just about headed off the challenges of pavel bittner and vito braet. with just four stages to go, another aussie ben o'connor remains the overall leader, but is just five seconds ahead of three—time

winner primoz roglic. and for all the history made by patrick mahomes, travis kelce and the rest of the kansas city chiefs. they're still starting the new nfl season chasing something that's never, ever, ever been done before. no franchise has won three super bowls in a row, but few are betting against the chiefs, who as defending champions play the first game of the season at home against the baltimore ravens. it's exciting, it's the first game _ it's exciting, it's the first game this season, everyone wants— game this season, everyone wants to _ game this season, everyone wants to come out and show how explosive — wants to come out and show how explosive they are and how much better_ explosive they are and how much better they got from last year. it's better they got from last year. it'sjust— better they got from last year. it'sjust a — better they got from last year. it'sjust a great better they got from last year. it's just a great opportunity to be — it's just a great opportunity to be going up against such a great — to be going up against such a great team. everybody over there — great team. everybody over there in _ great team. everybody over there in baltimore isjust tore-tier, _ there in baltimore isjust top—tier, and they've got some of the — top—tier, and they've got some of the best players in the league _ of the best players in the league. i think everybody is fired — league. i think everybody is fired up _ league. i think everybody is fired up to get out in front of the season and get it started. thet's— the season and get it started. that's coming up on friday.

quick update — jack draper has set up, but it's 5—5 against alex di minaur. another update later in the evening. nfl is back, we love it. thank you for that. a couple of developing stories we are following this hour in the us. the department ofjustice has just announced sanctions against some of the executives at the russian state—funded news outlet rt, who are accused of trying to influence the presidential election in november. the justice department is also targeting another kremlin—backed company that is coordinating some of this work, linked to 32 internet domains that are under the direction of the russian government. these websites were designed to appear to american readers as if they were major us news sites like the washington post or fox news, but in fact, they were fake sites. they were filled with russian government propaganda that had been created by the kremlin to reduce international support for ukraine,

bolster pro—russian policies and interests, and influence voters in the united states and in other countries. internal documents of the kremlin described the content as "bogus stories disguised as newsworthy events. " this malign influence campaign has been referred to as doppelganger. the russian public relations companies drove viewers to these websites by deploying influencers and paid social media advertisements. they also created fake social media profiles posing as us citizens who post comments on social media platforms with links to the sites. according to sda's records, it actively sought to, quote, according to sda's records, it actively sought to "eliminate the possibility of detection of the russian footprint". serious threats to the upcoming

elections. we're also tracking a shooting in the us. four people killed and nine others injured at a high school in georgia, just 50 miles north—east of atlanta. police say a suspect is in custody. helicopter video from wsb—tv appeared to show students being evacuated to a football stadium. in the past hour, the local sheriff has given this update. president biden says, we cannot continue to accept this as normal, and the vice president kamala harris has been speaking about shooting at her campaign event. . , . about shooting at her campaign event. ., , ., ., event. our hearts are with all the students _ event. our hearts are with all the students of _ event. our hearts are with all the students of the _ event. our hearts are with all the students of the teachers | the students of the teachers and their families of course, and their families of course, and we are grateful to the first responders and law enforcement. this was just a senseless tragedy on top of so many senseless tragedies. it's just outrageous that every day in our country in the united states of america, that parents have to send their children to school worried about whether or

not their child will come home alive. it's senseless. we've got to stop it. we have to end this epidemic of gun violence in our country once and for all. it doesn't have to be this way. it doesn't have to be this way! kamala harris speaking in the last hour. you can follow all the live detail on that shooting. we are expecting an update from the police and will not bring you that life when the police appear. —— and we'll bring you that live. we're going to move on to the contest and we have the first results. and the faller at the first is the former home secretary dame priti patel. many had thought it would be the former work and pensions secretary mel stride.

but he is through, albeit in fifth place. dame priti arguably one of the more recognisable faces in the mix, but only ia mps lent her their support. it was the former immigration minister robertjenrick who topped the poll with 28, followed by kemi badenoch on 22. james cleverly came in third, fourth was the centrist tom tugendhat. they five remaining will go through to a second vote next week. the number will be whittle down to four who will then the number will be whittled down to four who will then make their case to members at the upcoming party conference. for more analysis on this, let's speak to the financial times' whitehall editor, lucy fisher. good to see you. are you surprised? i thought mel stride was going to be the first, not priti patel. i was going to be the first, not priti patel.— priti patel. i was a bit surprised, _ priti patel. i was a bit surprised, to - priti patel. i was a bit surprised, to be - priti patel. i was a bitj surprised, to be quite priti patel. i was a bit - surprised, to be quite frank, although i thought it was between those two. i think people felt that priti patel would be a backwards looking choice. she's held a slew of front bench appointments, but

not for a while. she hasn't served most recently in rishi sunak�*s administration. she clearly couldn't command enough support today. it's interesting how much expectation management plays a role in the momentum that we see the candidates have. as you say, mel stride came in fifth, but because he had been expected to not even get through today or even to fall before the ballot was held this afternoon, there is a sense now as he calls it mel—mentum. i sense now as he calls it mel-mentum.- sense now as he calls it mel-mentum. ., , ., ., ., mel-mentum. i was aware he had been launched _ mel-mentum. i was aware he had been launched it! _ mel-mentum. i was aware he had been launched it! he _ mel-mentum. i was aware he had been launched it! he said - mel-mentum. i was aware he had been launched it! he said he - been launched it! he said he was concentrating _ been launched it! he said he was concentrating on - been launched it! he said he - was concentrating on annoyance mps. —— i wasn't aware. he hadn't told a big event with supporters, with merchandise, with a set b �*s speech. in that sense, i think you did come

behind in this —— set piece. [30 behind in this -- set piece. do ou behind in this -- set piece. do you think _ behind in this —— set piece. do you think we can draw any conclusions of how they finished at the top of the pile? obviously, robertjenrick first, but the bookmakers would say kemi badenoch is the more popular of the two. i say kemi badenoch is the more popular of the two.— popular of the two. i think jenrick came _ popular of the two. i think jenrick came ctrl - popular of the two. i think jenrick came ctrl he - popular of the two. i think jenrick came ctrl he on . popular of the two. i think. jenrick came ctrl he on top. popular of the two. i think - jenrick came ctrl he on top. as jenrick came ctrl he on top. as you say, kemi badenoch is the bookmakers's favourite. how priti patel supporters might split feels like a view of them could go to robertjenrick as well. he could keep up that sense of momentum. he's probably less known among the members. he hasn't served in the cabinet, but he's probably best known for his role as immigration in a stir. he hasn't held one of the senior or great officers of state at the top of government. keeping up the top of government. keeping up this momentum, topping the leaderboard today, i think seen as a big success by his campaign. as a big success by his

campaign-— as a big success by his cam aiun. ~ , . , campaign. will nitely that they lu , campaign. will nitely that they lucy. thank— campaign. will nitely that they lucy. thank you _ campaign. will nitely that they lucy, thank you very _ campaign. will nitely that they lucy, thank you very much. i campaign. will nitely that they lucy, thank you very much. -- lucy, thank you very much. —— we'll leave that there. around the world and across the uk — this is bbc news.

nvidia, the company that manufactures high—tech semiconductors for the ai industry, is now the third most valuable company in the world. but in trading yesterday, the value of the company fell io%, around $279 billion, which was the largest one—day drop in history for a us company. nvidia has been the cornerstone of the tech rally on wall street. last week, the company reported a i22% rise in second—quarter revenues, but investors were spooked by signs of a slowdown in growth — in particular around its next—generation of ai chips. on top of that the us justice department has opened an investigation, concerned

the company has made it harder for clients to switch to other semiconductor suppliers. with us to discuss is vicky price, the chief economic adviser at the centre for economics and business research. what is it that spooks the markets about the supply side of the business?— of the business? there's so much demand _ of the business? there's so much demand for _ of the business? there's so much demand for what - of the business? there's so l much demand for what nvidia of the business? there's so - much demand for what nvidia is in fact producing, particularly its new product, blackwell, aimed at advanced ai. there's going to be huge demand and they have actually been able to meet on that demand. for the future, they have to invest on awful lot in order to be able to do that. the thing they're worried about is the size of investment to keep up with the growth in innovation technology and the demand that's happening particularly since chat gbd has come into existence. ——

chatgpt. and the type of the ai we're going to see in the future, i think that is in itself creating a huge amount of excitement and optimism, but also stress behind how you can keep up. also stress behind how you can kee u. ~ . , , also stress behind how you can kee--u. ., ,, also stress behind how you can kee--u. ., ,_, keep up. which brings us to the d0] investigation. _ keep up. which brings us to the d0] investigation. they - keep up. which brings us to the d0] investigation. they think. doj investigation. they think there's been foul play.- there's been foul play. yes, there's been foul play. yes, they think _ there's been foul play. yes, they think it's _ there's been foul play. yes, they think it's about - there's been foul play. yes, | they think it's about whether they think it's about whether the company is making it harder for customers to move to other suppliers. we don't really know the exact extent of the types of concerns which the us department of adjustment has, but i think the market is for thatis but i think the market is for that is well. i think there is a big issue about whether the whole ai, the room we have seen may be have been exaggerated.

especially as the us economy is slowing down, it is showing signs of slowing down. modern—day to look. a big take has been taken on nvidia. —— two lip. it's been quite the ride and they've made a lot of profit as they've made a lot of profit as they've gone. but how concerned do you think fund managers will be about what happened yesterday and what it means for the rest of the market?- the rest of the market? what we've seen — the rest of the market? what we've seen is _ the rest of the market? what we've seen is that _ the rest of the market? what we've seen is that the - the rest of the market? what we've seen is that the whole | the rest of the market? what i we've seen is that the whole of the tech market — not everyone, of course. not necessarily nvidia, which saw a bit of an improvement. stock market overrule has been reflected, and as such a big company, its

so important for its size. there is a little bit of concern about where we are moving in the future. what will this do to profits because if you keep on investing, despite huge revenues, are you actually going to sustain what you seen before? vicky, always good to get your thoughts. sticking with al, we are going talk surveillance. if you were watching last night, one of our guests suggested the solution to this recent rise in snatch theft, might be improved use of facial and behavioural recognition. and i scoffed at that idea, given the stretch on police resources. but clearly i am ill—informed, because the economist reports today that here in the uk, there are 6 million cctv cameras — that's one camera for every 11 people for every 11 people in the country —

and that makes us the third most surveilled country in the world, behind only america and china. increasingly, police are using artificial intelligence to identify suspects, crimes, missing people. technology that was at its most efficient during the summer riots. those involved were found within days, arrested and charged. and the prime minister has pledged to increase the use of that technology and adopt ever more sophisticated ai systems that can improve the facial recognition we already have in place, which begs the question — how free are we? karen yeung is a fellow in law, ethics and informatics at the university of birmingham's law school and joins me now. i should know this, because we talk about al every week, but just how good is the facial recognition we're talking about? i recognition we're talking about? , , , , ., about? i guess it depends on how ou about? i guess it depends on how you define _ about? i guess it depends on how you define good, - about? i guess it depends on how you define good, but. about? i guess it depends on how you define good, but in l how you define good, but in terms of its capacity to accurately and automatically match the image of the person who's walking in front of the

camera, the facial image of a person whose face is scored on a watchlist or a database is much more powerful than it was five or six years ago thanks to advancesin five or six years ago thanks to advances in machines. in terms of speed, accuracy and level of automation, it's certainly far more advanced and that's why we see such desire amongst law enforcement to embrace it. north london use around 133 facial scans every minute. it does add urgency to the question of regulation. there is no clear determination on when it can be deployed and how it can be deployed. it seems to be left every police force, is that right? is be left every police force, is that right?— be left every police force, is that right? is not quite right, but there _ that right? is not quite right, but there is _ that right? is not quite right, but there is a _ that right? is not quite right, but there is a patchwork - that right? is not quite right, but there is a patchwork of i but there is a patchwork of overlapping laws that do reply to the use of this technology. but there's nothing specific to the use of facial recognition

technology by anyone, including the law enforcement authorities here in britain. that means there's an awful lot of discretion that is in practice left to the police to decide how they wish to deploy these technologies. it’s how they wish to deploy these technologies.— technologies. it's fascinating in the context _ technologies. it's fascinating in the context and _ technologies. it's fascinating in the context and what - technologies. it's fascinating l in the context and what we've been talking about in terms of grenfell. we seem to have a very lax attitude despite what politicians might tell us. if you look at what the eu does with its nexus ai act, they only allow recognition proved ijy only allow recognition proved by a judge —— new ai. protective policing is banned, so why do we have a light touch here? i so why do we have a light touch here? ~' ., . here? i think our civil liberties _ here? i think our civil liberties are - here? i think our civil liberties are not - here? i think our civil liberties are not as i here? i think our civil- liberties are not as strong as it claims to be in terms of in practice, but we can do anything we wish lawfully. but as this technology has become more advanced, the law

enforcement authorities have found it very, very hard to resist the temptation to use this more powerful technology to acknowledge people of interest. whether or not that translates remains to be seen in the veda is not very promising. in the veda is not very promising-— in the veda is not very promising. in the veda is not very ”romisin. ., ., ,, i. promising. karen, thank you very much- _ promising. karen, thank you very much- -- _ promising. karen, thank you very much. -- of— promising. karen, thank you very much. -- of the - promising. karen, thank you very much. -- of the data. l there are many other uses for al many of which we discuss on this programme, which gives me an opportunity to remind you that our weekly segment ai decoded is returning tomorrow 2030 bst. tomorrow, we will look at how ai is being used to better predict the weather and how it might help us prepare for extreme climatic events... ..which brings me neatly to this story — the forest ..which brings me neatly to this story — the forest fires in the amazon. we know from satellite monitoring that numbers of fires burning in rain forests injuly were at a 20—year high, and in august, they were at a 1a—year high. ai technology had identified almost 40,000 fire hotspots in the amazon in august — that's more than double were burning last august.

and from these pictures taken from space, you will see the huge spread of the smoke across brazil from these fires. this is sao paulo, brazil's largest city, almost covered in smog and smoke from the fires. i'm joined now by the scientist and meteorologist carlos nobre, co—chair of the science panel for the amazon. one of the problems i think has been a lack of rainfall. why is there so little rainfall this year? there so little rainfall this ear? , , , ., ., year? yes, because we have had the record-breaking _ year? yes, because we have had the record-breaking drought - year? yes, because we have had the record-breaking drought in l the record—breaking drought in the record—breaking drought in the amazon. that was related to a strong el nino in the central eastern equatorial pacific. there is the third—largest, strongest el nino on record.

also the record—breaking temperatures in the north atlantic ocean. those two factors induced this record breaking drought, starting the second half of 2023, moving all the way through now, 2024, so more than one year of the most severe drought in the amazon. also with heat waves and of course all the forest becomes much more flammable. however, more than 95% of fires were supposed to be arson. criminals going there and setting fire. that's an important qualifier. i know the forest is producing — or it did produce its own microclimate. is not being affected by the amount of forest we're losing —— is that? absolutely because the forests are worth tens of millions of

years of recycled water so efficiently. 30—40% of rainfall in the amazon depends on this recycling. now, with let's say the southern amazon, more than 25-30% of the the southern amazon, more than 25—30% of the forest has disappeared, replaced by a degraded plasters. these do not recycle very well, so we are changing the climate. the dry seasonis changing the climate. the dry season is four to five weeks lengthier. the forest is very close to keeping point —— tipping point. close to keeping point -- tipping point-— close to keeping point -- tipping point. president lula said he was _ tipping point. president lula said he was going _ tipping point. president lula said he was going to - tipping point. president lula said he was going to crack. tipping point. president lula| said he was going to crack on this. why is it he —— yc failing? this. why is it he -- yc failing?— this. why is it he -- yc failinu? ., �*, ., , failing? that's an interesting . uestion failing? that's an interesting question because _ failing? that's an interesting question because if - failing? that's an interesting question because if you - failing? that's an interesting question because if you look| failing? that's an interesting i question because if you look at dayforce station, president lula, president petro, we had a

reduction — 50% of deforestation rates in 2023 an additional 40% reduction in the first half of 2024. this is the largest deforestation reduction in brazilian amazon history. however, deforestation is reducing. however, organised crime is attacking the forest ijy crime is attacking the forest by fires because they know they are easily seen when they are trying to do deforestation. however, they go there, set fire and run away.— however, they go there, set fire and run away. carlos, inc. you very _ fire and run away. carlos, inc. you very much _ fire and run away. carlos, inc. you very much indeed - fire and run away. carlos, inc. you very much indeed for- fire and run away. carlos, inc. i you very much indeed for giving us some of your thoughts in the fires burning in the amazon rain �*s words. some live pictures in atlanta. that is the picture right now. we'll bring you that press conference as soon as it happens. stay

with us. hello there. look out for contrasting weather conditions across the country over the next few days. after having the wettest summer on record in scotland, the sunshine will come as a welcome surprise and it will turn increasingly humid. more cloud across eastern scotland and north—east england, but again, still quite warm. and then further south, we'll see a spell of heavy rain as an area of low pressure develops, and that front is going to lingerfor a few days at least. so, heavy rain across southern england and parts of south wales. you can see the first signs of that first thing on thursday morning. it's going to continue to drift its way steadily westwards and intensify. quite a lot of cloud spilling in off the north sea, but with lighter winds further north and west, here, we should get a little more sunshine. and in that shelter, temperatures will start to respond, so we could see highs perhaps on thursday afternoon of 22 degrees. now, let's take a look at what happens

through thursday evening, because that rain will intensify further. a spell of heavy rain moving its way across south—west england. that eases away, and then another pulse of wet weather is going to feed in towards the early hours of friday morning. don't forget — the brighter colours, the intensity of the rainfall. some areas could see as much as 80 to 100mm of rain before this low pressure pulls away. so another wet start across the south—west, with further areas of showery rain pushing into south—east england as well. an easterly wind will hopefully give a little more sunshine across eastern england, and more humidity and warmth to go with it, so temperatures potentially peaking at 25 degrees. we might see 25 in western scotland as well. into saturday, that area of low pressure potentiallyjust drifts that little bit further south, but still the risk of further heavy rain, sunny spells elsewhere, and again those temperatures into the mid 20s. but by the time we get into sunday, it looks likely that the low pressure will then start to drift its way

that little bit further north and east. so the midlands, parts of lincolnshire and perhaps east anglia could see more in the way of heavier rain. and cloudier conditions potentially further north as well, as the wind direction is now starting to change, so not quite as warm, not quite as humid. take care.

hello, i'm christian fraser. you're watching the context on bbc news. the simple truth is that the deaths that occurred were all avoidable, and those who lived in the tower were badly failed over a number of years. it should never have happened. the country failed to discharge its most fundamental duty — to protect you and your loved ones. human life was never| a priority, and we lost friends, neighbours, - and loved ones in the most horrific way — through greed, corruption, incompetence, i and negligence. the metropolitan police here in london say they will go through the report line by line, and look at the evidence they have already gathered. joining me tonight are susan bohne face, columnist at

the mirror, and former republican presidential candidatejoe republican presidential candidate joe walsh.
