concerns about the safety of the titan sub. a man is found guilty of murdering a custody sergeant after opening fire in a london police station in 2020. new measures to help uk mortgage holders struggling with rising interest rates are agreed by the big banks. hello, i'm lewis vaughanjones. welcome to verified live. we start with breaking news this hour. it is just coming to us in the last half an hour or so. just coming to us in the last half an hour orso. it just coming to us in the last half an hour or so. it is around the death of those five people on board the submersible which of course 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. let's get more on this. the worries

were over the craft�*s unusual design. it's non—spherical state, effectively, the reliability of the material it was made of, carbon fibre, and the fact that it also not answer any external, independent testing process. the bbc has been given a e—mail exchange between stockton rush, the ceo of oceangate who died in the incident, and a leading deepwater explosion specialist. the e—mails sent in 2018. rob mccallum warns stockton rush... he went on...

a few days later, oceangate�*s stockton rush replied... he told rob mccallum... guillermo, the former co—founder of oceangate. .. the next day, rob mccallum replied, in starkest terms, i think you are potentially placing yourself and your clients in a dangerous dynamic. right, let's get more on this right now. our science correspondent jonathan amos is standing by. this is quite a stark exchange of e—mails? it this is quite a stark exchange of e-mails? , ,., , , , e-mails? it is polite but it is very testy. one _ e-mails? it is polite but it is very testy. one has — e-mails? it is polite but it is very testy, one has to _ e-mails? it is polite but it is very testy, one has to say, _

e-mails? it is polite but it is very testy, one has to say, lewis, - e-mails? it is polite but it is very testy, one has to say, lewis, if. e-mails? it is polite but it is very l testy, one has to say, lewis, if you redo the whole exchange. should just describe who rob mccallum is. he is one of the world's leading subversive experts. the first time humans had been to all five of the deepest points in the world's oceans, he knows precisely what he is talking about. and he is essentially critical of stockton rush�*s approach to safety and the way that he has designed that sob, which we now know it imploded very close to the titanic on sunday, and those concerns, as you were saying, centring on the shape, the unusual carbon fibre construction and also the certification process, the idea that a third party comes in and runs the rule over your... gives you a piece of paper and says, it is as good as it can be. stockton rush�*s point is, that is not a

guarantee of safety. far more important is the way you operate. you need a culture of safety and i have got that. and this exchange essentially ends up so rob mccallum says, with the lawyers from oceangate getting in touch with him to threaten to sue him.— to threaten to sue him. jonathan, art of to threaten to sue him. jonathan, part of the _ to threaten to sue him. jonathan, part of the exchange _ to threaten to sue him. jonathan, part of the exchange there - to threaten to sue him. jonathan, part of the exchange there that i to threaten to sue him. jonathan, | part of the exchange there that we saw was the focus on the lack of external safety checks. talk us through the process, it was supposed to be happening. through the process, it was supposed to be happening-— to be happening. there is not a requirement— to be happening. there is not a requirement that you _ to be happening. there is not a requirement that you do - to be happening. there is not a requirement that you do it. - to be happening. there is not a| requirement that you do it. and to be happening. there is not a - requirement that you do it. and the point is that rob mccallum went through that process with the limiting factor. this was the sub that he basically led, it was taken down to the deepest points in the world's oceans by an american adventurer, but rob mccallum was in charge. they took that sub through a certification process, very

innovative sub indeed, probably more innovative sub indeed, probably more innovative actually then the titan submarine, and he believes who rob mccallum, that every sub that is operating in this domain should be going to that process. aeroplanes go through it, ships go through it, and a lot of high—technology go through that process, where an external agent comes in and says, these are the minim standards — are you meeting them in this design? i the minim standards - are you meeting them in this design? i don't want ou meeting them in this design? i don't want you to — meeting them in this design? i don't want you to speculate _ meeting them in this design? i don't want you to speculate clearly - meeting them in this design? i don't want you to speculate clearly here, i want you to speculate clearly here, but what do you think happens now? how does this shape this i ,any , any change in industry? we are seeinu a , any change in industry? we are seeing a lot— , any change in industry? we are seeing a lot of— , any change in industry? we are seeing a lot of people _ , any change in industry? we are i seeing a lot of people come forward from the industry saying they have also had safety concerns. there is debris on the ocean floor, they will try to pull those up in the next two days to give them to an investigation, and the investigators

hopefully will it be able to say precisely why this subfield, what it was about it that led to its destruction, and then of course everybody can have their say about these other issues —— precisely why this subfield. because they will have the facts in front of them. jonathan, thank you for that. we will head to boston now. the search effort was going on there, but the investigations go on. carl, what hope is there the information gathered now will be enough to find out exactly what went wrong? it is not clear yet _ out exactly what went wrong? it is not clear yet that _ out exactly what went wrong? it 3 not clear yet that we will out exactly what went wrong? it 1 not clear yet that we will ever come to a concrete or definitive conclusion about exactly what went wrong, but we do know that this investigation and what they will be looking at will centre on a few different things. in terms of

determining that crucial why, they can look at the debris itself. as we said earlier, there are five key part of this vessel they have found, they want to look at them closely. the carbon fibre for instance, you can see if there is any crack or fatigues that material. it is material that is known to be, when put under pressure, cancer to lose some of its strength. they will look at that. you might look at the end caps they found as well. there also some question or on the way that those titanium and caps were attached. maybe something between those might have led a leak in. these are the question they will start to answer. the second thing they look at is the debris field themselves. there are two debris fields they detected with these underwater drones, and they can look at the breadth of those. if they are very wide, that could indicate the titan vessel might have imploded much further up in its dive and then those pieces trickle down to the

bottom. if the debris field is a bit smaller, that could indicate the titan had completed its dive and it might have been much closer to the bottom of the ocean before it imploded, so these are some of things we expect the investigation to look at in the coming days, especially using those underwater, remotely operated vehicles. qm. remotely operated vehicles. 0k, carl, thanks _ remotely operated vehicles. 0k, carl, thanks very _ remotely operated vehicles. 0k, carl, thanks very much for that for the moment. just want to reiterate what we are talking about right at the top of the show, these e—mails and exactly what they show. so the bbc has been exclusively given an e—mail exchange between stockton rush, the ceo of oceangate who died in the incident, and a leading deepwater exploration specialist rob mccallum. in an e—mail sent in 2018, rob mccallum warned stockton rush... he went on...

a few days later, oceangate's stockton rush replied... the he told —— he told rob mccallum... the next day, rob mccallum replied, in the starkest terms... oceangate's lawyers then contacted rob mccallum and threatened legal action, and today we have contacted

them again and they say that they have no additional information. rob mccallum maintains no one should have gone in this submersible. so, that's the exchange that we have been given and seen exclusively here at the bbc. we will be getting plainmoor reaction to that a little later —— plenty more reaction to that. now, though, in the uk, a man has been found guilty of murdering a metropolitan police sergeant in a holding cell in croydon in south london. louis de zoysa's trial heard he used a revolver and handmade ammunition to kill matt ratana in september 2020. following the verdict, the police watchdog the independent office for police conduct called for hand—held metal detectors to be introduced widely in policing across england and wales. the case was heard at northampton crown court. our correspondent frances read is there for us now. yes, it was back in september 2020

that police stopped louis de zoysa on a routine stop and he admitted having cannabis, but then they also found ammunition as well, and so they arrested him. he happens to have autistic spectrum disorder as well and they took him in a van to the police station for what they failed to realise is that he had a revolver hitting in a holster under his left arm. they had searched him but they had not found the revolver, and the prosecution said that during the time he was in the van, he was able to move the revolver from the holster into his hands while in handcuffs. perley yet hypermobility and was able to do that. and inside the holding cell at croydon police station, he was then able to discharge four of these shots. let's look at the background now with daniel sanford. you're walking down the road with a duffle bag, all right, i which i believe may have stuff equipped to do a burglary. - what started as a routine stop

in the early hours of a friday morning ended with the killing of a police officer. quite quickly, louis de zoysa admitted he had drugs on him. ..non—medical cannabis. but pc rich davey then found seven rounds of ammunition. beep. i'm placing you under arrest for possession of bullets. i but despite a lengthy search, the officers somehow missed the antique revolver secreted in a holster under his left arm. in the van, de zoysa moved the gun from the holster into his hands, still cuffed behind his back. at the custody suite, sergeant matt ratana, who was in charge, ordered a search with a metal detector. we're going to take the cuffs off. stand up. but at that point, louis de zoysa produced the gun from behind his back and shot sergeant ratana in the heart. welcome to east grinstead rugby football club. i'm matt ratana, head coach.

matt ratana was originally from new zealand. a keen rugby player and coach, he was the son of a maori father and a scottish mother. his brother, james young, says that when he'd finished school, matt went to america on a tennis scholarship. we thought he was going to be a tennis champ and win us opens, but, no, he didn't. he went and became a cop. he went to england in '91. matt ratana served almost 30 years in the metropolitan police and was three months from retirement. he's never coming back. why? tell me why. his brother, who has a criminal record in new zealand and has spent time in police stations and prisons, can't believe the metropolitan police allowed a gun into a custody suite. what they've told us is they've changed the procedures and all these sorts of things, they've got metal detectors where you walk in through now.

i'm like, "well, they've got those in the police stations here. "they've had them for years." the two officers who searched louis de zoysa have been defended by theirforce. the officers, once they searched him on the street, louis de zoysa always remained in handcuffs. when the ammunition was found on him on the street, the handcuffs were moved from a front position to a back position. they've been praised for how they tackled the gunman during the shooting. he shot himself in the neck in the struggle and barely survived. the two arresting officers, i think without any thought, instinctivelyjumped on de zoysa to try and wrestle the firearm away and get it off him. de zoysa is permanently brain damaged. he can barely talk. in court, he used a whiteboard to communicate. he has autistic spectrum disorder but had a successful school career and learned to shoot with the army cadets. on the farm where he lived alone, he used his engineering skills

to make the nonstandard bullets for the 19th century revolver he'd bought online. he also purchased a holster to conceal the gun. it's not clear why he was near his parents with a firearm that night, but he had a bad relationship with his father, who has convictions for domestic violence. his lawyers argued that the shooting was the result of an autistic meltdown, but the jury decided it was murder. daniel sandford, bbc news, northampton. sergeant matt rata na sergeant matt ratana was described today as a gentle giant, kind, heroic, as we saw there, he had served with the met police for 30 years. you just a couple of months off retirement. and today, we heard from his partnerfor the first off retirement. and today, we heard from his partner for the first time. today, matt's murderer has been found guilty to taking his life in a cruel and cowardly manner, the effects of which have left me, his family, colleagues and friends without the love and camaraderie

he had with so many. i would like to thank everyone who has supported me, from my family and friends, the investigation team, the crown prosecution service, and the prosecution council and, as a whole, the metropolitan police. but today is about justice for matt. his life was taken too soon in the line of duty, doing a job that he loved. a cruel end to a lifetime of service and dedication protecting others. whilst the court case has concluded, the constant feeling of grief and loss continues. my love for matt, my gentle giant, will never end. he will never be forgotten. i again request that my right to privacy be respected. thank you.

there will be some major changes made as a result of this case, but perhaps the most significant is the idea of these hand—held medal detectors that are now being used across london in first responders vehicles. some 4300 of them are now used by the met police, but now today recommendation that they should be rolled out nationally. in addition to extra training for officers as well, but that's probably most likely will come out of this case, these medal detectors that police officers can use when they are out and about on patrol as well —— medal connectors. qm. -- 0k, —— ok, frances, thank you for that. around the world and across the uk, this is bbc news. lets take a look at some other stories making headlines across the uk. security workers at heathrow airport have accepted an improved pay offer, ending a long running dispute. members of the unite union had been planning a strike that would have disrupted some summer holidays. junior doctors are to strike in

england. the british medical association will be the longest walk out in the history of the health service. the electoral commission says data from last month's local elections in england shows that around ia,000 people did not vote because they were unable to provide an accepted form of photo identification. it was the first time voters in great britain have had to show id. warmer weather in may has helped push up retail sales the office for national statistics says they rose by 0.3%. online sales of summer clothing and garden furniture went up as the weather improved. garden centres and diy stores also saw growth. fuel sales also rose compared to april, but people bought less you're live with bbc news. banks and building societies will offer more flexibility struggling mortgage holders as rates soared. vendors have agreed to a 12 month

delay before taking repossession proceedings against barbers unable to pay. the move comes after bank buses met transla jeremy to pay. the move comes after bank buses met translajeremy hunt in downing street. —— met chancellor jeremy hunt. what will you do to help people with their mortgages?! summoned to downing street, mortgage lenders meeting the chancellor this morning to discuss how they can support homeowners after a 13th interest rate rise in a row. in castleford, west yorkshire, the impact of the decisions made in london is already being felt. i have actuallyjust bought a house last month, so, yeah, it affected us quite a lot. i've had a house before at a lower rate, so it has doubled per month, so it is a lot of money. it's the unknown of what will happen, if it will go up or down, and if we've made the right decision to fix for five years or should we have fixed for three and hope it would go lower? the bank of england increased rates by more than expected to 5%.

it is supposed to try to calm price rises on everything else. inflation, the rate of the soaring cost of living, is way above the bank's 2% target. but it will bring a huge shock for the hundreds of thousands of households due to remortgage in the next few months. and it is notjust a problem for homeowners. landlords say many will have to sell up or put up costs for renters. landlords like steve, who has decided to give up his two properties. the reality is landlords are making less money than ever today with the interest rates going up so high, and i would like to say to those tenants that we're actually poorer than we were a few years ago. the labour party and financial campaigners have been calling for more options for those struggling, things like interest—only payments. a response from the chancellor today after his meeting with the banks.

if you are anxious about the impact on yourfamily finances and you change your mortgage to interest only or extend the term of your mortgage and you want to go back to your original mortgage deal within six months, you can do so, no questions asked, no impact on your credit score. i think that will give people a lot of comfort. a relief for homeowners? the opposition leader remains sceptical. i think what people want is action, not words. what we suggested is a requirement on lenders to take these measures, because there will be many, many mortgage holders, many, many families across the country now even more worried about paying their mortgage. from bank bosses, some relief for those in the biggest financial distress. but with more interest rate rises expected, the road ahead will still be very difficult for many. what help is there? peter ruddick, bbc news.

let's talk now to angus hanton. he is the co—founder of the intergenerational foundation think—tank. thank you very much for coming on the programme. thank you very much for coming on the programme-— thank you very much for coming on the programme. thanks, hello. we are auoin to the programme. thanks, hello. we are going to talk — the programme. thanks, hello. we are going to talk quickly _ the programme. thanks, hello. we are going to talk quickly about _ going to talk quickly about intergenerational injustice. just quickly tell us what that means. we area we are a think tank researching fairness between generations, basically the younger generation have had a very poor deal in terms of housing, pension, incomes, the environ mental situation but also tax and this is central to the problem of payments for mortgages. let's get into that, then. now we know we talking about. fairness between the generations. this increase in interest rates, increasing therefore in mortgage cost. how does that play in? that affects the _ cost. how does that play in? that affects the younger _ cost. how does that play in? t�*isgt affects the younger generation far more than the older generation. i am a baby boomer, my early 60s, and my

generation have mostly paid off their mortgages, which were anyway quite small because they bought cheaply, and the younger generations are paying these far higher house prices and they are much more likely to be in the first—time buyer category and they typically will have bought, if they are buying in london, they will depend between 300,000- london, they will depend between 300,000— hundred thousand, if they bought outside london, they will have paid 250,000 average. typically 80% of that will be borrowing —— 300,000-400,000 as 80% of that will be borrowing —— 300,000—a00,000 as one of your interviewees said, repayment with these interest rates will have doubled. 50 these interest rates will have doubled. ., ., these interest rates will have doubled. ., , these interest rates will have doubled. ., ., doubled. so how do you try and address this, _ doubled. so how do you try and address this, then, _ doubled. so how do you try and address this, then, from - doubled. so how do you try and address this, then, from a - address this, then, from a generational fairness address this, then, from a generationalfairness point address this, then, from a generational fairness point of view? i think we've got a real dysfunctional housing market, it is notjust dysfunctional housing market, it is not just that we are not dysfunctional housing market, it is notjust that we are not building enough, we're not using what we got adequately. we are under occupying, or my generation is, a lot of second

homes, couples wrapping run in family homes. we are under using it, which is pushing up prices and keeping up prices so that is one thing, but the other big thing is we are taxing young people so heavily. as an organisation, we are not in favour of more or less tax revenue in total, but we are concerned about how it falls, and it falls very heavily on young people, with income tax, national insurance, in effect a gradual tax with student loans, and so young graduates are paying over 1;0% so young graduates are paying over 40% income tax where's the order generation, may be people in my position are typically paying less than that, partly because savings are taxed so lightly. you than that, partly because savings are taxed so lightly.— than that, partly because savings are taxed so lightly. you would be callin: for are taxed so lightly. you would be calling for a _ are taxed so lightly. you would be calling for a change _ are taxed so lightly. you would be calling for a change in _ are taxed so lightly. you would be calling for a change in the - are taxed so lightly. you would be calling for a change in the tax - calling for a change in the tax burden. how likely do think it is that will happen? you like it is quite possible for some i think the ground is shifting that way, and a lot of people like me here keir starmer singly no —— saying, no one wants to see the value of properties

fall, and yes they do. people my age have children who want to get on the preppy letter or get a bigger house or a fly, and for the sake of their children they want to see lower housing values, that is when the problems, that the political parties have seen advantage in keeping up house values and house prices, but i think the book of british people now want to see lower housing prices, and that that can be achieved. it is partly a matter of tax, it is partly building. matter of tax, it is partly building-— matter of tax, it is partly buildinu. �* , ., ., ., building. angus hanton from the intergeneration _ building. angus hanton from the intergeneration foundation - building. angus hanton from the intergeneration foundation think tank, thank you. i am intergeneration foundation think tank, thank you. iam lewis intergeneration foundation think tank, thank you. i am lewis vaughan jones. this is bbc news. good afternoon. plenty going on for the weather

over the next few days. in fact, we've got a change in the story as we speak. we've got rain around it this morning, not for all of us. this was glasgow earlier on. 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 to 22 celsius, but in the sunshine, still pretty warm with it, 26 to 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 to 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.

this is bbc news, the headlines... emails seen by the bbc show the ceo of oceangate, the owners of the titan submersible, repeatedly dismissed concerns about the safety of the sub. after a man is found guilty of shooting a custody sergeant inside a london police station, hand—held metal detectors could be introduced by police forces in england and wales. junior doctors in england are to go on strike for five consecutive days injuly, in their longest walk—out to date.

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.
