we start with more on our breaking news, after the death of five people on board the submersible, which went missing in the atlantic on sunday. the bbc has seen email messages showing that warnings over the safety of oceangate's titan sub were repeatedly dismissed by the ceo of the company. the messages were exchanged with a leading deep sea exploration specialist. the worries were over the craft�*s unusual design, its non—spherical shape, the reliability of the material — it was made of carbon fibre — and the fact it had also not been through any external independent certification or classing process. now the bbc has been exclusively given an email exchange between stockton rush the ceo of oceangate, who died in the incident, and a leading deep water exploration specialist rob maccallum. in an email sent in 2018, rob maccallum warned stockton rush...

he went on... a few days later, oceangate's stockton rush replied... he told rob mccullum... the next day, rob mccallum replied in the starkest terms...

oceangate's lawyers then contacted rob maccullum and threatened legal action. today, we've contacted them again and they say they have no additional information. rob mccallum maintains that no one should have gone in this submersible. our science correspondent jonathan amos has been tracking this story since the sub was first reported missing. this is a stark exchange your? it's a this is a stark exchange your? it�*s a fascinating exchange, actually. it is polite —ish, but it's also very testy indeed. we should perhaps explain who rob mccullum is, he's got a storied career in deep submersibles. he led the five deeps expedition — so this was the american adventure of the first person ever to reach the deepest points and all the world's oceans. so he certainly knows what he's

talking about. and his criticism of stockton rush here, the ceo of oceangate, centres around the approach of stockton rush�*s company, the materials they are using in the titan sub, but also around this lack of a certification process, the idea that you bring a third party in and they run the rule over your technology, then ultimately give you a piece of paper saying, "this ship is worthy, you can go use it," it won't guarantee that it'll not implode, as we saw on sunday, but that it meets the basic standards required. and as you say, the exchange ends up with the oceangate lawyers getting in touch with rob mccullum and saying, we don't want to have a legal issue with you over this exchange. and remember, it's all about safety at the end of the day, it's about this unusual shape,

the materials, the carbon fibre used in it which is very unusual in this sort of activity, and again, that certification process, and this sub did not go through it. and on the vessel on sunday was hamish harding, the british billionaire and adventure — he was great friends with victor for scoville, they went down to the bottom of the ocean and went into space together, as well. massive friends, and i asked victor this afternoon, did you have concerns about titan, given that you are an expert also on submersibles? it and i said, "did you speak to yourfriend, hamish harding, and say don't go in?" and victor said that he pleaded with his friend, pleaded with his friend not to get into the titan sub. . ~ with his friend not to get into the titan sub. ., ~ , ., , with his friend not to get into the titan sub. . ~' , ., , . titan sub. thank you very much for that, thank—

titan sub. thank you very much for that, thank you. _ more now on one of our main stories this hour — the guilty verdict brought against louis de zoysa, who shot dead metropolitan police sergeant matt ratana inside a police custody suite. he was able to use the revolver, despite having been handcuffed and body—searched, after bullets were discovered on his person. the independent office for police conduct has called for hand—held metal detectors to be introduced widely in policing across england and wales. our home affairs correspondent daniel sandford has been speaking to met police deputy assistant commissioner stuart cundy — here's what he had to say. sadly, i never worked personally with matt, and i remember getting the call on the day that he'd been fatally shot, and struggling to comprehend what what had occurred and what had happened. but very quickly, having spoken to sue, matt's partner, his son luke, his colleagues at croydon, and indeed across the met, quickly realised that matt was a larger—than—life

character with a huge stretch, notjust here within the metropolitan police, or indeed across the uk, but also to police and across the world. he'd served here within the met police, he'd also served with the police in new zealand, and he'd worked across london in both local policing and specialist roles. and i think it's a testament to matt that all those that have spoken about him, their personal memories, their personal recollections, there's still some that reallyjump out to me that aren't widely known. and it was shortly after the terrible events in september 2020 that the detainees that he had previously cared for, some of those came back to the custody centre, to pass on their own respects. and i think that's the mark of the man who cared deeply for others has left a lasting legacy across policing. but of course, that isn't just known for his role as a police officer, you know, as a partner to sue, he has a son, luke, but he was huge,

huge into his sport — known by many for his rugby coaching, which i think really epitomised his leadership and his coaching skills. but he was also an all—round sportsman, he really was. he won the national policing tennis doubles in some years gone by, and so his impact on his colleagues, his family, those who knew him and those that didn't know him so well, ijust think is absolutely immense and a testament to him. and how much of a disaster, then, was it that he was shot by a suspect in his own custody suite? i, like most people, have always asked the question, how could it possibly have occurred, that a man who was on the streets of london with a gun, has been able to shoot a police officer, in essence, within the confines of a police station,

in one of our custody custody suites? the devastating impact that's had on max's partner, sue, and his family and his colleagues is is absolutely immense. and, perhaps uniquely and certainly for me, in all of my time in policing and all the investigations i've undertaken or been responsible for, very quickly, i and my colleagues in the investigation knew exactly what occurred because we had all of the events, both on body—worn video, on cctv from the van, and indeed cctv from the custody suite. so we were able to quickly identify the full events, this chain of events that led to such a terrible and a tragic outcome. so picking up on that, how was it then that louis de zoysa managed to get a gun into that

custody suite undetected? so i've been able to watch and rewatch all of that video and audio footage, that had all of the events from when louis de zoysa was first seen on the streets of south london, all the way through to the fatal shooting of matt. i've had the opportunity to speak to the officers — and that's notjust the arresting officers, but all those involved to try to save matt's life, and indeed did save the life of louis de zoysa. now the arresting officers, when they stopped de zoysa, he told them he had cannabis on them, so they handcuffed him literally straightaway — for their protection, and because he said he had drugs on them. the whole sequence of events on the street lasted for over 15 minutes, this was not a cursory search. the officers, whilst louis de zoysa was handcuffed, searched him, his two arresting officers. they found on him ammunition,

which they described at the time to be bullets. now, this is in the early hours of the morning, this is a dark street in south london — and when officers search somebody on the street, it is one of our most intrusive powers, we recognise that, but conducting a full search needed to establish if somebody does have something secreted on them, we're not able to do that in the street. so we do need to take people, and louis de zoysa had been arrested, so he was taken to a police station, and he was taken to the police station. and for those that have watched some of the footage that's been shared, that was shown in court, matt ratana, who was the custody sergeant, authorised de zoysa's detention for the purpose of search. this wasn't de zoysa being placed in a police cell for the purpose of investigation. the arresting officers believed — well, should we say that their concerns were heightened ?

and if you do watch the video, you'll see in the custody suite, they're holding the hand—held metal detectors. matt authorises de zoysa's detention to be searched. and it's at that moment that de zoysa somehow produces a firearm from behind his back and fatally shoots matt. what we heard at trial, when de zoysa gave evidence, is that that revolver — and it was a legally—purchased revolver at the time — had been in a holster, which he indicated it was under his left armpit. so in essence, a firearm concealed in the holster that was concealed under his arm. it wasn't found by the officers on the street, but i know, having spoken to them, having watched the footage, the evidence, having read the evidential statements, that their concerns were undoubtedly heightened when he was taken to the police station to be further searched. daniel sanford asking the questions there. junior doctors in england are to go on strike for five consecutive days next month.

the action, which will run from thursday, 13july, to tuesday the 18th, is an escalation of their long—running dispute over pay. with more here's our health correspondent smitha mundasad. so it's confirmed, a five—day walk out? at so it's confirmed, a five-day walk out? �* . , so it's confirmed, a five-day walk out? �* . ~ so it's confirmed, a five-day walk out? �* ., ~ ., ., , out? a five day walk out, the dates are 13 july through _ out? a five day walk out, the dates are 13 july through to _ out? a five day walk out, the dates are 13 july through to 18 _ out? a five day walk out, the dates are 13 july through to 18 july, - are 13 july through to 18 july, starting are 13july through to 18july, starting at 7am and finishing at seven a:m., andjunior starting at 7am and finishing at seven a:m., and junior doctors will walk out of the emergency and routine care for those five days. this is now the fourth set of strike dates that have come this year from junior doctors— there was a three day strike in march, a four—day in april, and a three day strike that just ended a week ago, and the british medical association is saying they are calling a strike because since that strike just a week ago, they haven't heard from the government in terms of reopening talks and negotiations in this to

butte —— dispute over pay. they state this 35% pay rise is, in their view, a compensation for pay raises. the government says it is deeply disappointed there'll be another strike and that this will be deeply disruptive patients. they say from their perspective, that the british medical association has turned its back on negotiations because the government has said that if strikes are paused, they can continue their talks. they say they've already made an opening offer of 5% pay rise they've made to other unions, and they're willing to consider nonpaid things like working conditions. the british medical association says that working conditions are deteriorating, that lots of doctors are suffering from burn—out too, and this offer is not a credible officer. so it's hard to see where things will move from here — and it's worth noting this is not the only doctor strike we see you next

month. consultants and senior doctors are being valid right now on strikes that could happen on 20 july, sojust strikes that could happen on 20 july, so just days after the junior doctor strike ends. the royal couege doctor strike ends. the royal college of nursing is consulting its members over future strikes, as well, so this pay dispute is far from over stop thank you very much for that. an update on the war in ukraine reported the black sea fleet had installed enhancements to their base that likely included an increased number of trained marine mammals. so to try and work out what's going on here, we can speak to an author and expert in unconventional naval warfare. thank you forjoining us on the programme. so what is going on here, why is the russian navy training dolphins? the

here, why is the russian navy training dolphins? here, why is the russian navy trainin: dolhins? , , ., ., , training dolphins? the russian navy has a long-standing _ training dolphins? the russian navy has a long-standing programme - training dolphins? the russian navy has a long-standing programme to l has a long—standing programme to train dolphins, and also beluga wales and seals. in the context of this, they are doing it to try to defend against underwater threats, particularly divers, so ukrainian special forces and that sort of thing, they are anti—diver assets. i've never heard a dolphin described as an anti—diver asset — in what way is it, how does it do this? we as an anti-diver asset - in what way is it, how does it do this?— is it, how does it do this? we don't have that good _ is it, how does it do this? we don't have that good a _ is it, how does it do this? we don't have that good a view _ is it, how does it do this? we don't have that good a view as _ is it, how does it do this? we don't have that good a view as to - is it, how does it do this? we don't have that good a view as to the - have that good a view as to the nuances of the russian programme, but we would expect, based on what has been done in other countries, that the dolphins would be trained to approach anti—diver, anyone swimming that they find and either attach something to that person so that someone else can deal with them, or potentially even deliver some sort of fatal attack. the dolphins will be good about that,

but the problem is they cannot detect whether the person they are approaching his friend orfoe, so it's more likely they'll mark the person, ratherthan it's more likely they'll mark the person, rather than attack them directly. but it's very effective. that was going to be my question, it doesn't sound like a very effective way of doing anything. can dolphins and other mammals really be trained well enough?— well enough? absolutely, and if you think about it, _ well enough? absolutely, and if you think about it, they _ well enough? absolutely, and if you think about it, they are _ well enough? absolutely, and if you think about it, they are better - think about it, they are better swimmers than any human, it doesn't matter how good a special forces guy you are and how good you are at swimming, you'll lose against any of these mammals. but dolphins can see you long before you see them, obviously they have sonar, they operate at night and can be trained to come up from behind a swimmer, there's not much a human can do at all. �* . �* , , ., , there's not much a human can do at all. �* . �*, ,., , ., all. and what's the history of this? does every — all. and what's the history of this? does every military _ all. and what's the history of this? does every military around - all. and what's the history of this? does every military around the - all. and what's the history of this? l does every military around the world have this, how long has it been going on priscilla it's a very rare

capability but it's not unique to russia. it started with the swedes training seals a long time ago, but that was short—lived. the real programme to note is the us navy's programme, they trained dolphins as well and also sea lions, and the ussr during the cold war started training ussr during the cold war started trainin: ., , , , ., ussr during the cold war started trainina ., , , , ., . ., , ussr during the cold war started trainina ., , , , ., . ., training dolphins, beluga wales and seals, and that's _ training dolphins, beluga wales and seals, and that's what _ training dolphins, beluga wales and seals, and that's what we _ training dolphins, beluga wales and seals, and that's what we have - training dolphins, beluga wales and seals, and that's what we have the l seals, and that's what we have the continuance of that today. i can safely say _ continuance of that today. i can safely say i _ continuance of that today. i can safely say i think _ continuance of that today. i can safely say i think we've - continuance of that today. i can safely say i think we've all - continuance of that today. i can safely say i think we've all learned something. thank you very much for coming on the programme, extraordinary to find out, thank you. extraordinary to find out, thank ou. . ~' extraordinary to find out, thank ou. . ~ , ., russian officials say that ukraine has attacked a bridge linking southern ukraine to the crimean peninsula with long—range british missiles. our bbc verify team has seen a video which shows the moment a missile struck a road bridge. richard irvine—brown from bbc verify is in the newsroom with more. let's have a look at the location

shown in the video, and why it's so important. what we have here is the crimean peninsula — controlled by russia — and the rest of ukraine. the road bridge offers one of the few land crossings between the russian front lines to the north and the annexed peninsula. let's have a look at the footage of the missile strike together. now, keep your eyes on the top left of the screen for two reasons — one is the entrance of the missile which struck the bridge, and the other is a quick flash of a timestamp on the cctv. now we can be confident we are talking about the right bridge, because we've verified five other videos recently which show the same supports, the fences, the poles at one end from both ukrainian and russian social media channels. and we know from eyewitnesses reported across various media, the strike happened at dawn. we know that dawn was 4.a6am yesterday, so a timestamp of 5.07am fits in perfectly. this is a still image shared by the local russian—installed governor of the region.

he claims ukraine are responsible for the strike, and they were supplied with uk storm shadow cruise missiles. now this is what one of those looks like — it's about five metres long with narrow wings. we know the uk did supply ukraine with storm shadow missiles in may, and we know that since then, two strikes — one in berdyansk and one in herson oblast — have far exceeded their previous range, which would be consistent with storm shadow missiles. and if we pause the footage here, this is the clearest shot we have of the missile. compared to the size of the bridge, it certainly looks five metres long, and the fine trajectory at which it hits the bridge would be consistent with a storm shadow missile. however, russian media, who have also claimed it's a storm shadow missile, have shared images of debris — but we're dubious about it and are still checking it out. security staff on the doors of uk nightclubs, bars, and music venues say they're facing increasing levels of abuse. the organisation representing them says people who attack staff should face the same legal penalties

as those who target emergency workers. the bbc has heard from more than 1,000 staff about abuse, including physical assaults, racial taunts, and sexual harassment. ashleyjohn—baptiste has been finding out more. for door supervisors, dealing with a rowdy customer or two as part of the job. but what happens when people take things too far? gary has been a door supervisor for nearly four decades. a punch by a customer on shift left him hospitalised. he was diagnosed with post—concussion syndrome — a mild traumatic brain injury, with symptoms including anxiety and memory loss. it's left him unable to work. what has the emotional and mental impact of this been? you look at yourself — "how did this happen to me? "why is it happening to me?"

but... again, i told you, my brain fades out here and there there. so can you just ask me the question again? erm... i can see that you're a bit emotional. yeah, yeah. it is emotional. you don't... you don't expect to be assaulted at work. i'm frightened that i might get punched again and, you know, i don't want... i don't want to die. i don't want to die at work. and gary's not alone. 20—year—old olivia has worked at some of nottingham's busiest venues for almost a year, and has faced sexual harassment from the onset. a lot of groping, people trying to put their hand down my trousers. they say things like, "i will find you," and they say, "i will kill you." like, there's been times where they've told me that they will rape me. that's not unusual for that to happen. if it's been you, the target

of the abuse, you've got it going through your head of, "are they going to come back for me?" do you know who you're bleep dealing with, you bleep? - door supervisors are employed by private agencies, but licensed and regulated by the security industry authority. but in a sector with no official trade union and little job security, industry bodies are calling for increased support and legislation to protect these workers. i see us as the fourth emergency service. we are there before the ambulance service. the police service. we are the first persons on scene. we sign up for helping you when you're sick, when somebody's attacked you and you need help. i don't go out of my way to kick you out of a club if you're having a good time. it's only if it's necessary. and i don't want it to be necessary. so be good people when you go to my club, 0k?

some heavier bursts of rain, but already it's starting to fragment as it pushes its way steadily eastwards. but we've got rain into parts of north—west england and wales. the best of the sunshine further south and east, so not a bad morning so far across surrey, as you can see. it looks likely that with the cloud and the rain, it'll be just that little bit fresher for many of us. top temperatures generally around 16—22 celsius, but in the sunshine, still pretty warm with it, 26—27 celsius. that's just nudging into 80 fahrenheit. now, as we go through this evening, still going to see some showery outbreaks of rain for a time drifting its way eastwards. this south—westerly flow feeding in a lot of cloud. it'll be misty and murky, but it's also going to drag with it more humid air, so it will be a mild night, an uncomfortable night for getting a good night's sleep, 15 or 16 degrees. so a warm start to saturday morning leading into a pretty warm and increasingly humid day as well. it will be cloudy, misty and damp at times along west—facing coasts. a few more organised showers into the north—west of scotland, but there'll also be some sunny

spells for many and it will feel pretty warm generally across the country. we're looking at 17—25 celsius in scotland and northern ireland. highest values — 29, possibly 30 not out of the question somewhere across southern and eastern england. now the high pressure just drifts off into the near continent, but we still keep this southerly flow, but a frontal system pushing in from the west, so on sunday, a real contrast to the story, best of the sunshine, and still pretty hot with it, south and east. but as this front moves in into that very warm and humid air, it's going to trigger some sharp, intense thundery downpours. noticeably fresher behind it, but hot and humid ahead of it with highs of 30 celsius. now, as that rain clears away through sunday evening into monday, that fresher air will start to take over. and areas of low pressure look likely to start to move in from the north and west, so a change into next week. yes, it will be a little bit fresher in comparison to of late

and there'll be showers or longer spells of rain at times. welcome news for the gardens.
