for the company. twitter says mr zatko's allegations are inaccurate and inconsistent. it says he was sacked in january for ineffective leadership and poor performance. our north america tech reporter, james clayton, has this assessment. twitter�*s ceo had a nickname for him, "mudge". this is a really senior person, and he is alleging all sorts of things going on at twitter. the key one for me is bots. he is saying that twitter deliberately undercounts how many bots it has. now, elon musk is trying to buy the company, or at least he was. he then pulled out, saying that twitter had done just that, undercounted the bots. now you have someone inside, the former head of security, saying exactly that. there is a court case in october, where twitter are going to try and force elon musk to try and buy the company. this is brilliant news for elon musk. he has literallyjust tweeted an emoji of a cartoon person

whistling. a clear this is devastating for twitter. they want to force elon musk to buy the company. these revelations will make that much, much more difficult. twitter has denied the allegations, and has accused mr zatko, known as "mudge", of opportunism. vivian schiller is twitter�*s former global chair of news. she gave me her reaction. first of all, i am kind of surprised they're going after mudge, who was widely considered, for many decades, one of the best and most ethical and most centred security experts in the world. his credentials are unimpeachable, both personally and professionally, so i am not sure that's the best way for them to go about it.

i don't know what would be in it for him to make these allegations, if they were not true. you mention the number of false accounts, or bots. that's really only one of the allegations. frankly, i'm not even sure it's the most disturbing, but certainly it is relevant, in light of the legal procedures that are going on between twitter and elon musk. his complaint about trying to get out of the deal is he feels that he has been misled by twitter management about the number of bots on the platform, and certainly today's revelations has given that a lot of ammunition. yeah, on that, vivian, where do you see that going from here, in terms of how this case, or these allegations, might play into elon musk�*s current case with twitter? elon musk was handed a huge gift today. his lawyers have said they have already subpoenaed mudge for this kind of information, but if what he is saying — and again, there is no motivation for him to make this

up, and considering his credibility, it would be surprising — he has alleged the way twitter management has been describing the number of bots on the platform has been misleading. i want to be careful. it is not untruthful, it is just the way they've positioned the accounts they are looking at, that less than 5% of the accounts are bots, is frankly, if you read the entire document, quite misleading, and really plays into elon musk's hands. so it'll be quite an interesting set of hearings in september. vormer global chair of news for twitter. vormer global chair

of news for twitter. let's turn to ukraine now, and a un security council is holding a meeting about the zaporizhzhia nuclear power plant, which has been under russian control since march. moscow called for the meeting, amid reports of continuing shelling around europe's largest nuclear station. the us and uk said russia could easily resolve the situation by ending its war in ukraine. wednesday is ukraine's independence day. it also marks the six—month anniversary of when russian troops crossed their border to start a war that had been predicted for a number of months. speaking on the eve of the anniversary, our kyiv correspondent, james waterhouse, reflects on the mood of the ukrainian people. well, inside ukraine and inside kyiv, it's very much a constant. it's actually reminding me of the build—up to the invasion, where you had warnings from the west, from the us state department, around concerns of a russian escalation. but of course, six months on, things couldn't be more different. this is a country still under a full—scale invasion, but authorities are wary.

they are banning public gatherings. this time last year, there was a huge military procession, in a show of strength. this time around, the main street through kyiv has destroyed or captured russian tanks on display. they've really been quite popular with people, as they walk through, take a bit of interest, pose for pictures. and it's another marker, as ukraine marks 31 years of independence tomorrow. it's also a reminder ofjust how under threat their sovereignty is. so we may well see some high—profile visits tomorrow. we're told friends of ukraine have been invited. how wise that is, given the heightened security risk, isn't clear. the us embassy has urged citizens to leave. that's quite an escalation, in terms of a precaution, to the irritance of president zelensky. so it will be low—key tomorrow. the city does feel quieter, and it's not just about tomorrow. i think it's the next three days that there are concerns around russia increasing its long—range missile strikes,

he certainly notjust in kyiv, but across the whole of ukraine. that was james watt hours reporting on that story for us. to malaysia now, where najib razak, the former malaysian prime minister convicted of money laundering, linked to the i—mdb embezzlement scandal, has lost a final bid to overturn his 12—year prison sentence and has been sent to jail. the massive embezzlement of billions of dollars from the imdb state fund was one of the world's biggest financial scandals, and reverberated from malaysia and singapore to wall street and beyond. our south east asia correspondentjonathan head has more. chanting. he was once the most powerful man in the country — untouchable, even. but najib razak arrived for the final stage of his appeal, knowing that the odds were now against him. every attempt to overturn or even delay the 12—year prison sentence he'd been

given, thwarted by a judiciary, which stood firm behind the original verdict. translation: iwill not get a judgment based i on the principles of fair trial. i did not get it. the son of a former prime minister, he was groomed for power, and held office for nine years in a country where the ruling party had never lost an election. stories of spectacular greed and corruption brought thousands out onto the streets in protest. chanting. but investigations into huge losses from the state—run investment fund, known as imdb, went nowhere. the department ofjustice has filed a civil complaint, seeking to forfeit and recover more than $1 billion in assets associated with an international conspiracy to launderfunds stolen from imdb.

even when the united states launched its own investigation, mr najib looked secure, in a country where power has rarely been accountable. but at the last election, four years ago, an opposition coalition, led by malaysia's most renowned political figure, mahathir mohamad, once mr najib�*s ally, rode the public yearning for change to an unexpected and historic victory. mr najib, seemingly in shock as he accepted the verdict of the people, was untouchable no longer. his home was raided. more than 200 top—priced designer handbags, still in their boxes, were among the many luxury items seized. it is the biggest seizure in malaysian history, and multiple criminal charges soon followed. for those who have dreamed of a cleaner politics

in malaysia, this is surely a moment to savour. but najib razak remains wealthy, influential and popular in some parts of malaysian society. it's probably too soon yet to write off his political career. jonathan head, bbc news, bangkok. it's a big day for the us primaries in florida, a new york state and oklahoma — where voters get to decide who will represent their party in the upcoming mid—term elections in november. it is the last big election day before those midterm polls, which will determine who controls congress until the next presidential elections in 202a. our north america correspondent antony zurcher is in florida, he told me what we should be looking out for. well, i am well, iam here well, i am here at ron desantis's campaign desa ntis's campaign headquarters. he desantis's campaign headquarters. he will be speaking here later this evening here at miami. marco rubio, the republican senator

who is running for re—election it was also speaking here, both will be running without opposition. they will be the republican nominees but marco rubio ran for president in 2016. ron desantis is rumoured to be eyeing a presidential bid in 2024, so both of these have had or have presidential ambitions and their success in the elections against november in the democrats to determine what their ambitions are, going forward. this could be the launching pad for a ron desantis presidential campaign. so is this the sort of race to watch then, in terms of the entire campaign, as we head to the mid—terms later this year? well, you know, ithink watching what is going on with the democrats as you mentioned, and charlie crist and nicky freed running for that nomination. crist is a moderate who has a long record in office, endorsed by the

establishment. nicky freed won state—wide election here at the past two time she has run, so she has the potential for running, but she has more potential. then another clash about whether to go with a moderate or the person who is more than left. which one has a better chance of getting elected and once being elected in acting democratic policies and reforms? there are also races. in new york, one that pits two democratic congressmen and women, the city of new york will also be interesting to watch. there is also a special election for a congressional seatin election for a congressional seat in new york thatjoe biden carried by about two percentage points. if the proper components win, it could be hit they will do well. —— if the republicans win. it might not be as pronounced as people thought, that democrats, because joe thought, that democrats, becausejoe biden�*s legislative

successes, because of the importance of the abortion issue, because of a reduced inflation in the past few weeks may be making things a little better for democrats. that is definitely another one to keep an eye on. just in the last few minutes, i want to tell you about news that has been coming in, it has been projected that the democratic us representative charlie crist has won the party's nomination to run in florida, pitting him against republican incumbent, ron desantis. more on that story as and when we can. stay with us. you're watching newsday on the bbc. still to come on the programme — the asian—american, hollywood star, ming na—wen, tells us about the enduring appeal of her role in the disney movie, mulan. he's the first african—american to win the presidential nomination of a major party,

and he accepts exactly 45 years to the day that martin luther king declared, "i have a dream." as darkness falls tonight, an unfamiliar light will appear in the south—eastern sky. an orange glowing disc that's brighter than anything, save the moon — our neighbouring planet, mars. horn toots. there is no doubt that this election is an important i milestone in the birth- of east timor as the world's newest nation. it will take months, and billions of dollars, to repair what katrina achieved injust hours. three weeks is the longest the great clock has been off duty in 117 years, so it was with great satisfaction that clockmaker john vernon swung the pendulum to set the clock going again. big ben bongs

this is newsday on the bbc. i'm karishma vaswani in singapore. our headlines: twitter�*s former security chief says users' personal data has been put at risk, along with us national security. the company has denied the allegations. the us orders its citizens to leave ukraine as kyiv prepares for heightened attacks from russia on independence day. less than a week ago, finland's prime minister sanna marin sparked criticism with a video of her partying which led to her taking a drugs test. now, the 36—year—old has apologised for a controversial photo taken at her residence. the picture circulated by finnish media shows two women kissing, lifting their tops to bare their torsos, and covering their breasts with a sign that says �*finland.’ i asked our news reporter gareth barlow why there so much attention

has been paid to this. it's an interesting question because if you go onto social media or the internet you will find thousands, millions of pictures like this — people having fun, but like you say, this picture was taken back in july in her official residence in helsinki, and thus, critics say is this appropriate behaviour to take place in a government building, government funded building? the internet you will find thousands, millions of pictures like this — people having fun, but like you say, this picture was taken backin you say, this picture was taken back injuly in her official residence in helsinki, and thus, critics say is this appropriate behaviour to take place in a government building, government funded building? for her part, sanna marin has said is not appropriate and she has apologised as you say. but i think might be happening is she is trying to take control of the narrative because she has made no secret that she likes a party and having a drink with friends. there are elections coming up in 2023 in finland andi coming up in 2023 in finland and i think there might be narrative control here. at the end of the day, this might not be something people are used to sing in a conservative society such as finland but sanna marin

is just a person such as finland but sanna marin isjust a person having such as finland but sanna marin is just a person having fun with your friends. she is just a person having fun with yourfriends. she has not done anything wrong as she proved yesterday when a drugs test was released because of the political pressure when she proved herjudgement was not impaired. it is a bit of damage control now. that is maybe why she has apologised this time and she has not in the past. yeah, and that criticism as you referenced, gareth, coming from the opposition parties of course but at the same time there has also been huge support of her, hasn't there, from women in finland and elsewhere?— from women in finland and elsewhere? ~ , elsewhere? absolutely. if you look on social— elsewhere? absolutely. if you look on social media - elsewhere? absolutely. if you look on social media there - elsewhere? absolutely. if you| look on social media there are montage after montage of women doing the same thing — having a drink, having a party and at the end of the day nothing wrong. what we're seeing here is an interesting point in a society that is more and more people who have grown up with the internet move into positions of power and responsibility. we are going to see more footage. at the end of the day, if you are 18 or 88, you enjoy having a lovely might not have the footage on a smart

phone, it might not have the selfie or the slightly embarrassing shot but more people are going to and we will see more of it. i think into, three, four, 510 four, 510 years time, will there be such a fracas? i very much doubt it. gareth barlow speaking to us a little bit earlier. onto the next story now. nasa has released never—seen—before pictures of the solar system's largest planet, jupiter, which were taken last month by the new super space telescope, james webb. the images show auroras, giant storms, moons and rings in detail that astronomers have described as �*incredible.’ and they certainly are. here is our science correspondent helen briggs. jupiter in a whole new light. the famous great red spot, a storm larger than earth, visible as a radiant white dot. glowing light shows — or auroras — dancing at the poles. faint rings, and two of the planet's many moons, standing out against a backdrop of glittering galaxies.

scientists say the stunning new images, artificially coloured to make the features stand out, are better than they could ever have hoped for. these images are so much more than just pretty pictures. yes, they are pretty, aesthetic, glorious. but they're crisp, they're detailed, they're showing parts ofjupiter, of its cloud cover, that we haven't really appreciated before. this isjupiter, as seen through the hubble space telescope. hubble's more powerful successor, the james webb, was launched in december. and since the summer, it's been sending back extraordinary images of the universe. over the years to come, the telescope will be peering ever further back in time, transforming our knowledge, both of distant worlds and of planets in our

own back yard. helen briggs, bbc news. who doesn't want to look at the universe like that? i certainly do. earlier i spoke to planetary astronomer imke de pater, who is one of the leaders of the project, and i began by asking her whether she expected the images to be so good. no. idid no. i did not expect to be this good. it is really amazing. in particular, seeing all this detail onjupiter itself, and detail on jupiter itself, and next detail onjupiter itself, and next to it, it's a million times fainter ring, and little moonlights that you can see at the tip of the ring. it is quite remarkable, and on top of that, you see these really faint galaxies in the background. i mean, we would have never, ever dreamt of seeing that. have never, ever dreamt of seeing that-— seeing that. yeah, we're looking _ seeing that. yeah, we're looking at _ seeing that. yeah, we're looking at some - seeing that. yeah, we're looking at some of - seeing that. yeah, we're looking at some of yourl seeing that. yeah, we're - looking at some of your images now, i believe, and even in my

colleague, helen briggs report, as you point out, images of galaxies that we have complete never thought we were able to see in our lifetimes, all of this of course thanks to the james webb space telescope. where do you see it being put to use next, and what other work do you think it could be applied to?— applied to? well, it can be a- lied applied to? well, it can be applied to _ applied to? well, it can be applied to many _ applied to? well, it can be applied to many of - applied to? well, it can be applied to many of the - applied to? well, it can be l applied to many of the solar system objects and, of course, to the universe, but we are quite interested in the planets, in our solar system, satellites and a small objects, and the data that we now have in hand ofjupiter will tell us a lots aboutjupiter itself, about the atmospheric dynamics, interplay between chemistry and bombardment by charged particles from outside of the atmosphere, from its magnetic fields. we really will learn a lot aboutjupiter that we lot about jupiter that we always lot aboutjupiter that we always have been puzzled about,

what it would be like, what the physics really in the atmosphere is telling us. and, finally, ming—na wen will be known to a lot of people as the voice of disney's mulan, but she's also starred in the medical drama er and is now playing fennec shand in star wars: the book of boba fett. wen sat down for an exclusive interview with bbc 100 women, talking about why she thinks mulan is a feminist, her experiences growing up as asian american, and typecasting in hollywood. it's always going to be a struggle in this business, no matter who you are, but being asian, being a woman, you know, it's a double negative sometimes. the wonderful thing about being in disney animation is that when it hits all the right notes, it becomes classic,

it becomes universal. i never really believed that mulan could have been that, only because it was so specifically a chinese folklore, and the fact that her legacy, her character, has survived the decades is astounding. i definitely see mulan as a feminist, but in the best way. mulan has all the attributes, not only to inspire women and also to inspire men, to inspire the boys, to appreciate and respect a female like her. i wake up every day and i'm still astounded that i am i was alone, in a very white neighbourhood, as an asian girl. you cannot imagine what that is like for that little girl, who came from china and who grew up in a white neighbourhood and having to struggle, to suddenly

realise that her dreams came true. stereotypes, they are created to sort of pigeon—hole a group of people. and in hollywood, many times, casting directors, producers, they use that stereotype because they are comfortable or it is what they know. when i came out into the real world, one of the challenges i had was always going after roles that were not specifically written for asians, and there were not that many back in those days, trust me. diversity is almost becoming the norm. we had crazy rich asians, we had thejoy luck club, we've got awkwafina. what is great is that, now, when these people are in a room, on a set, they are not looked at as tokens. it is really becoming more a norm, and that is what i love about it.

that was ming—na wen. that is it from us. thanks so much for watching. hello, there. there was a lot of late august sunshine to be found on tuesday. it was a beautiful day across much of scotland, as you can see from highland, but here, temperatures sat in the high teens, low 20s. now, further south and east of that, again, lots of sunshine, but it was hot and it was humid with it. in fact, suffolk saw the highest temperature on tuesday afternoon of 29 celsius. as we move into wednesday, this weather front will produce some rain, but it's also the dividing line between fresher air to the north and west and somewhat humid conditions continuing across much of central and eastern england. so, yes, we will see some rain, some of it heavy at times across west wales and then gradually pushing into north west england. a few isolated showers

further north and west, but here it will be predominantly dry, breezy as we go through the day, but those temperatures once again sitting in the high teens, maybe low 20s. to the south and east of that weather front, our temperatures again on the high side, 25—30 degrees, and it will be very humid with it as well. now, as we move through wednesday evening, into the early hours of thursday morning, our weather front doesn't move very far very fast, and when it does so, it will weaken off considerably. so a band of cloud and a few patchy showers moving across the pennines, but to the south and east of that, there's a risk of some thundery downpours developing in the south—east. and with the temperatures staying on the high side, 17 or 18 degrees, some of those showers really could turn quite heavy and thundery. so during the early hours of thursday morning, we could see across essex, kent, suffolk and maybe north norfolk some sharp showers drifting their way steadily eastwards. they will be fairly isolated and only on those eastern fringes, but any rain in these areas is certainly going to come as welcome news. cloudy skies following

on behind, brighter skies behind, with a scattering of showers in the far north—west. noticeably fresher for all — 15—24 degrees the high as we move out of thursday. now, friday, into the start of the weekend, sees a weather front push into the far north—west and the wind direction changing. so it looks likely that the far north could stay cloudy with outbreaks of rain at times, potentially. elsewhere — and, yes, it's a bank holiday for northern ireland, england and wales — dry, settled but fresher.

this is bbc news. we will have the headlines and hours straight after this programme. this week, more clean, green fun in the sun, with battery robots, solar cars and electric boats.

in an unassuming garage in the netherlands, there's
