# hold me closer, tiny dancer. and did she do it again? what the critics said about britney spears' comeback single with eltonjohn. hello and welcome to bbc news. very good to have you with us. we begin with the united states. donald trump has reacted angrily to the publication by the us government of a heavily redacted affidavit that led to the unprecedented search of his florida home. the sworn statement says there was "probable cause to believe" that there are "additional documents" with classified information still at mar—a—lago, and: the affidavit�*s conclusion makes the case that there is probable cause:

..would be found on the premises. donald trump has denied any wrongdoing. with more details, here's gareth barlow. this is the remarkable document used to justify one of the most historic fbi raids in us history. amid the blacked—out text, agents argued they had probable cause to believe, in their words, that evidence, contraband, fruits of crimes or other items illegally possessed would be discovered at the former president's mar—a—lago estate. the criminal investigation and eighth of august search began after the national archives, which maintains white house records, identified classified files among 15 boxes recovered from mar—a—lago in january this year. an fbi review recovered 184 classified documents, including 25 marked as top secret. it is unprecedented. since the presidential records act of 1978,

and which i helped draft, that this is the first time a president ever carted off to his home documents that were prepared in the course of his presidency. those documents belong to the united states, not any individual. the former president, along with his legal team, argues he has the right to declassify the documents, and he has already done so. legal experts question those claims — as did, on friday, president biden. "well, ijust want you to know i've declassified everything "in the world! "i'm president. "i can do it all." come on! declassified everything. i'm not going to comment. i don't know the detail. i don't even want to know. let the justice department take care of it. of the 32 pages that triggered the search of mr trump's beachfront property, 21 were blacked out and several contained no visible words at all, the fbi arguing that revealing the identities of witnesses could potentially lead them to being subjected to harm, including retaliation, intimidation and even threats to physical safety.

the justice department was also concerned that if they laid out the whole scope of their investigation and how they knew what they knew, that could possibly give a roadmap to president trump and his legal team for possibly defending against charges that could be forthcoming. what the document doesn't address is what agents discovered in the 11 boxes they retrieved from mar—a—lago earlier this month. investigations expected to continue now behind closed doors as it reviews the documents and potentially calls more witnesses. we may hear nothing more until we learn if criminal charges will be laid. gareth barlow, bbc news. let's get more on the legal background to this. earlier, i spoke to lisa kern griffin, professor of constitutional law and evidence at duke law school. she told me more about the affidavit, in particular that phrase that kept popping up — "probable cause". probable cause is the legal standard that is required

in order to get a search warrant, so the magistrate judge here determined when a search warrant was conducted that the government had probable cause to search for evidence of the three crimes that are outlined in the search warrant. and the affidavit that was released in part today contains the background facts that establish that probable cause. that affidavit that you mentioned, heavily redacted, as we have seen. what is likely to be behind those big black blocks? well, the government actually identified five categories of information that it was concealing with the redactions, and it is important to bear in mind that there are a number of people besides the government who know what is behind those blocks. one of them is, of course, thejudge who has reviewed the original affidavit, reviewed it in order to approve the search warrant, and then reviewed it in order to determine whether these redactions were proper. and, of course, trump himself knows much of the information

that is redacted in the affidavit. the reason for the redactions and the reason that they are so extensive is, one, because the government is trying to protect civilian witnesses who have provided information about the documents, about the activities at mar—a—lago and presumably about trump's knowledge of what was in those documents and where they were. the government is also trying to protect law enforcement officers who have, of course, unfortunately in the wake of execution of the search warrant, been threatened by some of trump's supporters, and the government put in its filing about why it did the redactions, that that was one significant concern. the government is trying to protect the course of the investigation. they have made clear that this is an ongoing investigation, that there may be multiple targets of this investigation and that they do not want to reveal a roadmap for where the investigation is going. there is also grand jury information which is secret by law, and they have expressed some concerns about the privacy of some of the individuals

described in the affidavit. in addition to his claims of this being a political witch—hunt, mr trump has said "this is legally pointless "because i am protected by executive privilege". where does he stand on that? not on very firm ground. executive privilege belongs to the current president of the united states, who is not trump. as a former president, he has the same privileges that other citizens would have, and executive privilege is not one of them. sometimes, there's a little slippage here and he seems to be talking about, or his supporters seem to be talking about, attorney—client privilege — which, of course, may apply to a small number of these documents — but the justice department has made it clear that it has a filter team that is reviewing the documents for that purpose. and in terms of the potential penalties for the investigation here, what does mr trump face because, of course, he has not been charged yet? he has not been charged with anything and there is no reason to think that that is forthcoming in the short—term, so it is difficult to speculate about what any ultimate

charges would be and, of course, about what any penalties would be. the search warrant affidavit names three offences. the obstruction ofjustice — that is also in the redacted affidavit materials. there is mention of mishandling of government documents, which is a federal offence. and then, of course, there is the much—talked—about espionage act, which really just refers to national defence material and not necessarily to spying, per se. those are the three named offences that supported the government's right to obtain and then execute the search warrant, but there could be many other offences as well, including, potentially, violations of the presidential records act, which are mentioned in the redacted affidavit. professor lisa kern griffin. a national emergency�*s been declared in pakistan after almost 1,000 people died following severe monsoon flooding that began injune. more than 33 million people have been affected by the country's heaviest rainfall in decades.

hundreds of thousands of homes have been destroyed and thousands of people have taken refuge in relief camps. the worst—affected areas are in the provinces of balochistan and sindh in the south, from where our correspondent pumza fihlani sent this report. moving to higher ground. families wade through the water with the only belongings they could salvage. in southern pakistan, many streets have been turned into rivers. families have set up tents on the few roads that are still visible. it's been more than ten days of heavy rains and yet, the streets of sukkur are still flooded. this is one of the main roads linking this community to the outside world. now, something has also happened here — many of the people of this community say they've lost their homes to the floods. what they could do was they moved to slightly higher ground and they've managed

to set up temporary shelter. now, they say to me they're worried about more rains coming and they don't know how long they will be able to stay here. just behind this new tented community is where their homes used to be. from up above, devastation as far as the eye can see. balochistan and sindh provinces have suffered the worst destruction — homes, roads and infrastructure reduced to rubble. around sindh, the provincial government has been distributing aid, but the need outweighs its resources and are appealing for help. this man's family has lived here for more than 50 years and his home was destroyed within minutes, he tells me. translation: we have lost everything. - all our belongings are gone. the only thing we managed to save is our lives. the water's might has taken notjust homes, businesses too. into this video, a new hotel, one of the largest in the area, was washed away within minutes.

the owner told us he watched helplessly as it came down. it's becoming clear to the people trapped in these remote communities that the worse is far from over and yet, all many can do is sit and hope — hope that the coming storm will be a little more forgiving. it's a vulnerability many had never imagined. pumza fihlani, bbc news, sukkur. let's get some of the day's other news. in his nightly address, the president of ukraine, volodymyrzelensky, has said that the situation at the zaporizhzhia nuclear power plant — which is occupied by russia — remains dangerous. the plant was temporarily disconnected from the power grid on thursday for the first time. mr zelensky once again demanded that the un nuclear watchdog visit the plant as soon as possible. a senior mexican official says

an army colonel ordered the killing of six of the 43 student teachers who disappeared in 2014 in guerrero state. the head of the truth commission said the six students had been kept alive in a warehouse for at least four days before a local army commander ordered them to be killed. last week, the truth commission published a report calling the disappearances of the student teachers a state crime. the suspended thai leader prayut chan—ocha has said he will continue in his role as defence minister. his comments on twitter are his first direct address to the public since a court ordered him to cease his duties as prime minister while it reviews his term limit. thailand's constitution stipulates a term limit of eight years for the prime minister. the main opposition party says he took power in a coup in 2014 and so, his time is up. the american pharmaceutical company moderna is suing rival firms pfizer and biontech for patent infringement in the development of the first covid vaccine approved in the united states.

the company says pfizer copied mrna technology developed by moderna years before the pandemic. stock markets in the us have ended the week sharply down following tough comments by the head of the country's central bank, the federal reserve. its chairmanjerome powell said the bank must continue to raise interest rates to stop inflation from becoming a permanent aspect of the us economy. his words sent us stocks into a tailspin with markets tumbling 3%. our business correspondent michelle fleury explains. jerome powell, in his widely anticipated speech, effectively said that the federal reserve, america's powerful central bank, was not done, that it would would continue to raise rates, that they would remain elevated for a long time. now, for investors, this was the worse possible news. they had hoped he might sort of dial things back and say things were looking a bit brighter but, in fact, it was the opposite and as a result of that,

you saw the us markets falling sharply, all down around 3%, the dowjones industrial average tumbling 1000 points in one day. part of the fear that they have is notjust higher rates but this idea that if the fed gets it wrong, you could potentially tip the us economy into recession if growth stalls. it is no surprise that mr powell referenced paul volcker, a fed chairman during the �*80s, who, as a result of high inflation, was forced to raise interest rates to 20% and tipped the us economy into recession. i think that's the point powell is trying to make to ordinary americans — that there is going to be pain along the way, but it is worth it to avoid that. you are watching bbc news. our main headline: the usjustice department has released a heavily redacted version of the document it used to obtain a search warrant for donald trump's florida home. experts investigating the deaths of thousands of fish

in a river between poland and germany say the cause remains a mystery. scientists are trying to identify what they say was probably a pollutant added to the water, triggering what they describe as a catastrophic chemical chain. meanwhile, people living upstream have told the bbc they first reported fish dying as early as march. jenny hill sent this report from szczecin in poland. a river that should team with life, instead gives up its dead. fish are dying in the 0der in the thousands. in a single day, they told us here, they pulled 16 times of corpses from the water. after eight days of this, he just feels numb. and it is not over yet.

wejoined numb. and it is not over yet. we joined these scientists as they test the water to try to establish what happened. they suspect an as yet unidentified substance polluted the river and that caused a type of algae to flourish. its toxins then killed the fish. you can really sense the frustration, the concern here, and that is because they still don't know what has caused this. and while they cannot identify it, they can tell along the offence will last, and worse than that, they can't say that it won't happen again. it may be that the hot summer, low water levels played a part. even now, a wave of poison is still spreading down river. translation: the scale of its ecological disaster is president in poland. it is of its ecological disaster is president in poland.- president in poland. it is a catastrophe. _ president in poland. it is a catastrophe. we _ president in poland. it is a catastrophe. we have - president in poland. it is a. catastrophe. we have never found so many dead creatures,

is to blame, he says, but we will probably never find out who. there is despair here at the damage done, but determination as well to better protect these waterways and the precious life they contain. jenny hill, bbc news. an it company in california says it's developed software that can alter the accents of people working in call centres. sanas says it wants to reduce racist abuse faced by staff in places such as india and the philippines. but critics say the technology is trying to make people sound "white". you're about to hear two voices — the first, a natural one, and the second after it has been through the voice—altering software. have a listen. south asian accent: hi, this is alex _ from the customer service aid. how are you today? great to hear. american accent: hi, this is alex _ from the customer service aid. how are you today? great to hear. what do you make of that? earlier, i spoke with winifred poster, a sociologist

from the university of washington in st louis, who has done extensive research on call centre workers. this is what she had to make of it. i think there are many, many problems with this kind of technology that range from lesser to greater harm. one of the problems is that it doesn't solve the main problems of customer service, which is that when a customer calls a company, they have a problem. so, regardless of what accent is being communicated to them, they may still be angry that their computer doesn't work, or that they were unable to get a refund for a purchase, etc. another problem is that it's unfair to the worker, especially in the global south, when they have to engage in these kinds of deceptive practices as a regular part of the job. it follows a range of practices

that i have documented in my research called — about national identity management, in which workers, as a routine for their interactions, have to change their name, they have to speak in a different type of accent, they have to adopt different conversational styles, and sometimes explicitly lie about where they are. this creates a range of different emotional, psychic, mental, practical problems for workers and they often don't end up staying in thejob for very long, maybe a matter of months, in part because of these kinds of practices. the company, if i canjust come in there, the company says four of its founders are immigrants, 90% of its workforce are immigrants — it says this just is about really blurring the lines and making things easier, really, when people have these interactions with call centres.

isn't itjust as simple as that? it is true that many workers will — may say that this kind of levelling of accent may make theirjob easier in the short term. but as i said, it creates other problems, which is that for instance, it increases the deception that a customer has to experience when they are calling a company, and i am sure that many of us have had the experience of doing various technologically mediated interactions where we don't know whether the person on the other end of the line is actually a human or not. and i don't think that customers like to be deceived. in my experience, when i was doing research inside call centres, customers

actually often really enjoy the opportunity to be able to ask where the worker is, and then learn about them and their culture. it is a moment, it's an opportunity for cross—cultural learning. it is interesting you mention that, because we had that example before, and i am sure the company wants to constantly improve, but it did sound a little robotic. and i think most people would rather talk to a person than a robotic voice — isn't thisjust going to make things worse? it seems like it is, in my mind, to me. and also, it has the added problem of reinforcing stereotypes and biases around access and language. and it privileges whiteness in society in general, it feeds into that rather than helping to break that down and, you know, create a more empathetic, knowledgeable world.

the remains of what could be the largest dinosaur ever discovered in europe are being excavated in a back garden in portugal. the fossilised skeleton of a sauropod was discovered in the central city of pombal in 2017 when a man began building work on his house. sauropods were the biggest of all dinosaurs and the largest land animals to have ever lived. palaeontologists say the huge reptile was about 12m tall — that's about about 39 feet — and 25m or 82—feet long. music now, and britney spears has released herfirst single since being freed from her conservatorship, the legal arrangement which saw her father control most aspects of her life for more than a decade. the song is a duet with eltonjohn based in part on his 1972 hit tiny dancer. our music correspondent mark savage has been taking a listen. # hold me closer... the unmistakable sound of britney spears. # oh, hold me closer, tiny dancer...

this is the first time fans have heard new music from the singer since 2016... chanting free britney now! ..and it's the first since she was freed from a 13—year legal arrangement that stopped her making basic decisions about her personal life. what am i gonna do now that the conservatorship's over with? speaking on instagram last year, britney said that returning to music might not be her first priority. i'm just grateful, honestly, for each day and being able to have the keys to my car and being able to be independent and feel like a woman. and owning an atm card, seeing cash for the first time, being able to buy candles. it's the little things for us women, but it makes a huge difference. it was music legend eltonjohn who eventually tempted the star back into the studio. # and i think it's gonna be a long, long time... he was planning a follow—up to cold heart — a duet with dua lipa that became a global number one

last year — and it was his husband, david furnish, who suggested getting britney on the track. they met in los angeles this summer to record it, and elton previewed the song to diners at a french restaurant earlier this week. # hold me closer, tiny dancer... released at midnight, the song's already had a warm welcome. "i hope she gets all the support in the world "after the hell she's been through," said one fan online. critics weren't so kind, with the telegraph calling hold me closer "one of the most pointless records in pop history", although the guardian said the song was "filled with power and poignancy. " writing on twitter, britney said she was "overwhelmed" to be singing with one of her heroes. # hold me closer, tiny dancer...# her fans hope that this will be the first of many new songs. mark savage, bbc news.

sounds like she has come back even stronger. you can reach me on twitter — i'm @richpreston. thank you for watching. see you next time. hello. we ended the week with some fairly quiet weather, and that's how it's going to continue into the weekend. and, of course, for many of us, it is the august bank holiday weekend. here's the summary — plenty of sunny spells on offer, a few showers too. but it will become breezy, particularly by monday, and really quite cool on the north sea coasts. but at the moment, the weather is quiet. weather systems out at bay in the atlantic. there's a chance that this weather front will brush the north—west of the uk through the course of saturday. but this is what it looks like early hours of saturday — clear spells in many areas bar the odd local shower. temperatures, 15 in london, around 8 degrees in the lowlands of scotland. so here's that weather front, which will brush parts of northern ireland and the western isles of scotland, just spits and

spots of rain here and there. but i think through the afternoon, sunny spells will give way to showers in a few areas, perhaps the pennines, central england, in the south too. and saturday also sees the notting hill carnival or the return of the notting hill carnival since before covid. so, here, sunny spells in london and a small chance of a shower. onto the forecast for sunday, and again, anotherfine day, and i think fine weather for most of northern ireland and the western isles of scotland as well. best temperatures, i think, in south—western parts of the uk, 25 for cardiff, closer to the low 20s there on the north sea coast. now on monday, we are going to see this high pressure strengthening across the uk, and also around it, we'll develop quite a strong breeze blowing off the north sea, which will drag in some low cloud. so from the aberdeenshire coastline, the north—east, all the way to east anglia, possibly the kent coast, it may actually turn quite cloudy. in this situation,

coastal areas really will be quite chilly. the best of the weather will be out towards the west, and again, the highest temperatures here, perhaps around the mid 20s for cardiff. but if you are in scarborough, for example, it could only be 16 degrees with a keen breeze off the north sea. how about the week ahead? with high pressure in charge, the weather, again, is not looking bad at all. very little rain in the forecast with steady temperatures in the mid 20s in the south, the high teens in the north. have a great weekend.

this is bbc news. the headlines: the usjustice department has released the legal evidence used to justify the unprecedented search of donald trump's florida home. large parts of the affidavit were blacked out to protect witnesses and the integrity of the ongoing investigation. mr trump has called the operation a witch—hunt. the authorities in pakistan have issued emergency warnings of severe flooding in the north—west of the country as the heaviest monsoon rains in decades continue. near the city of quetta, homes, railway tracks and road bridges have been washed away. stock markets in the us ended the week sharply down following tough comments by the head of the central bank. the federal reserve chairman warned that controlling inflation was the key to combating the fastest rise in prices in nearly four decades, but said it would be painful.
