said the british government stands in full support of the czech republic, and called the actions of russian intelligence services �*reckless and dangerous�*. gareth barlow reports. the czech republic, 2014. an explosion at an arms depot leaves two people dead, damages nearby homes and sends smoke rising from the ruins. following years of investigations, the czech authorities allege these two men were behind the blast. alexander mishkin and anatoliy chepiga, also known as alexander petrov and ruslan boshirov, the two russian intelligence officers the uk says in 2018 carried out the poisoning of a former russian agent on british soil. announcing the news on saturday, the czech foreign minister said 18 russian diplomats would now have to leave the country. translation: as foreign minister of the czech republic, i made the decision to expel all personnel at the russian embassy in prague, identified by our secret services as officers of russia�*s secret services.

within 48 hours, 18 staff of the russian embassy must leave the czech republic. the czech prime minister said the two suspects were members of the gru, russia�*s military intelligence service. a senior russian parliamentarian called the claim absurd. it all follows tit—for—tat expulsions of diplomats by the us and russia at the end of last week and western concern over the build—up of russian troops along the ukrainian border. the latest development a serious escalation in a region that is already on a political knife edge. gareth barlow, bbc news. with me now is our security correspondent, gordon corera. quite an extraordinary story. i was all this come out now? this happen seven years ago but it is really the aftermath of the salisbury poisoning

in 2018 which is led to this investigative trail which is, the role of these two individuals in both the events. essentially, investigators in the czech republic began to look at this instant fashion the last couple of years, this explosion, which had been thought probably an accident at the time and killed two people and they discovered an e—mail requesting access to the site with the details of two people who wanted access to the side and when they looked at the pictures of the two people they realise that it was these two had been linked by the uk to the salisbury poisoning is a piece of evidence suggested these people came in under false identities and went, it appears, first to prague and then stayed near the side of the explosion. and then suddenly left the country. so that evidence has come together in hindsight after the salisbury attack and suddenly that

incredibly significant and allow them to say we think this was russian military intelligence behind the blowing up of our arms depot. what were they trying to do? what was their mission? it what were they trying to do? what was their mission?— what were they trying to do? what was their mission? it appears to be a link to our— was their mission? it appears to be a link to our bulgarian _ was their mission? it appears to be a link to our bulgarian dealer- was their mission? it appears to be a link to our bulgarian dealer who l a link to our bulgarian dealer who is using that depot was then targeted by the same units the members of this part of russian military intelligence and six months later he was, it appears, poisoned, another assassination plot although he survived. and it looks like he was storing weapons in this depot in october 2014 so it looks like part of a campaign against him by russian military intelligence and these same operatives then go author and carry out the salisbury attack a few years later. and always been slowly unravelled now.— unravelled now. these two characters. _ unravelled now. these two characters, we _ unravelled now. these two characters, we know - unravelled now. these two characters, we know theirl unravelled now. these two - characters, we know their faces characters, we know theirfaces because after the salisbury attack they said they were only in salisbury to go to the cathedrals

and to admire its famous spire. that is riuht. and to admire its famous spire. that is right- these _ and to admire its famous spire. trisgt is right. these these and to admire its famous spire. twat is right. these these names to come to salisbury and the same identities to salisbury and the same identities to initially go to prague in october 2014 but then real names were identified. after those names came out they were put on russian tv and said they were sports nutritionists who went to see the cathedral spire in salisbury and russia has dismissed all of these allegations at their binders. this dismissed all of these allegations at their binders.— at their binders. this unit of russian intelligence, - at their binders. this unit of russian intelligence, it- at their binders. this unit of russian intelligence, it has| at their binders. this unit of i russian intelligence, it has got at their binders. this unit of - russian intelligence, it has got a chequered past, really. and quite a few, well, episodes like salisbury, really that seems to show incompetence. ht really that seems to show incompetence.— really that seems to show incometence. , ., , j incompetence. it shows they're dangerous. _ incompetence. it shows they're dangerous. i— incompetence. it shows they're dangerous, i think, _ incompetence. it shows they're dangerous, ithink, incapable. incompetence. it shows they're| dangerous, ithink, incapable of dangerous, i think, incapable of killing. we can see now that they killed two people in the czech republic with this explosion. and as a woman was killed in the aftermath of the salisbury attack so there is

political struggle with the west. in the past, the gru has not suffered political damage from apparent embarrassments. they set the moment that russia feels that it can and must operate these kind of covert sabotage operations which are nudging closer to the boundaries of what we would consider to be an act of war because it can get away with it, basically. until quite recently, the czechs have been quite reticent but they have now pivoted. a senior conservative mp has warned the uk prime minister borisjohnson he�*ll lose the support of the so—called �*red wall�* voters in former labour, unless he resolves the row about lobbying. several inquiries have begun into the former uk prime minister david cameron�*s communications with cabinet ministers while he was working for the collapsed finance firm, greensill capital.

i asked our political correspondent nick eardley what�*s been happening on the story today. we have heard about david cameron lobbying ministers in behalf of this company about potential conflicts of interest in the civil service and in the cabinet as well but in a lot of these, it seems like the bills haven�*t been broken so we are increasingly heaving calls for the rules to be tightened. let�*s listen to labour�*s shadow cabinet office minister, rachel reeves. what we have seen this week is that tory sleaze is back and it is bigger than ever and we need real change to the _ stored trust in our democracy and in the very essence of public service which matters to so many of us and matters to people in our country. what we want to see, to have a proper enquiry,

not shared by one of borisjohnson's friends, a very close friend of the conservative party the man doing the review. but a proper independent enquiry which has teeth and has a chance to make recommendations on how to clean this up because this isn't just about this company. it is the tip of the iceberg. there are £2 billion of contracts that have gone to friends of the conservative party and there is growing feeling that there is one rule for those at the top and another for everybody else that we need to route out of our politics. played by very keen to point this at the conservative party. it is interesting she was asked by the former welsh is vice minister who was told the body overseas these things that he should not take a job with a steel company after he left his job as first minister.

he did take it. she was suggesting that the two things are different but clearly, you know, the spotlight is on this in a way that it has not been for some time. the argument from the government is that they are going to look into this. at my last count there are seven enquiries that are now ongoing. some by mps and one is you just had their from a senior lawyer who is looking into this for the government. the environment secretary, george eustis, was on the marr show this morning and his argument is that david cameron has not done anything wrong, he has not broken any rules but the government needed to look into everything. we have got these various reviews ongoing including the government one. 0ngoing review, come on? once it is concluded, once all those parliamentary enquiry is looking at this have concluded i'm sure some of them will make policy recommendations and of course government will look at that. i am not saying things could not tweaked or improved but i am

saying it was changed about ten years ago and _ fundamentally the question should be less about who is going to who, the _ question is much more how did ministers act those conversations are done that, as far as i can see, the answer is that they did not do _ any special favours. you will notice in that answer their that he hinted thatjust may be the government would look at strengthening the rules at some point. what are the political ramifications of all of this? we�*ve got a senior conservative mp talking about, you know, warning borisjohnson that he could lose support the country because of this. that is right, sir bernard jenkin who has been a tory mp since 1992, saying some of those people who voted conservative for the first time ever at brexit will look at this and it may erode their trust in the political system. i think there is a nervousness around

westminster that this is really starting to cut through. it has been going on for weeks and as we said earlier the spotlight is on this issue. it has not been for some time. there is a nervousness that is starting to impact trust in politicians and they think the more this continues the more that nervousness will grow. as you say, it is a row that is continuing. we�*ve got the seven enquiries currently under way. you have the private one which will be the government�*s lawyer looking into it and we won�*t see much until the conclusion. the three different groups of mps are now looking at this as well and that means we face the prospect of david cameron and a bunch of cabinet ministers giving evidence in public. the period of official national mourning has now come to an end. the funeral service was watched by 13.62 million

tv viewers in the uk. our royal correspondent nicholas witchell reports. drawn up in the spring sunshine on the castle�*s quadrangle were the military detachments. they stood with heads bowed and rifles reversed. the scale was smaller than would have been the case without the pandemic — though that�*s hardly something that would�*ve troubled the duke. he, after all, had choreographed much of what was to follow. the land rover hearse, which the duke had helped to design, moved to its position by the state entrance.

the duke�*s coffin was borne on the shoulders of a bearer party from the grenadier guards. the coffin was covered with the duke�*s personal standard and surmounted with his sword and naval cap, and a wreath from the queen. with great care, it was placed on the hearse. behind the hearse were members of the royalfamily, who were walking to the chapel, headed by the prince of wales. a royal salute sounded and the first sight of the queen, accompanied by a lady in waiting, in the state bentley, taking position as the order was given for the procession to step off. he issues command. bell tolls.

band plays. bell tolls. close by was one of the horse—drawn carriages the duke had taken such pleasure in driving. on the seat, his cap and gloves. among the members of the family walking behind the coffin were princes william and harry — the focus of so much attention — walking with their cousin peter phillips between them. bell tolls. the procession wound its way past the castle�*s round tower. by the side entrance to st george�*s chapel, other members of the royal family stood with their heads bowed. the queen made her way into the chapel, pausing to look

back as the hearse moved on down the hill. on the wreath of white roses and lilies on the coffin was a card, on which were the handwritten words "in loving memory". before they entered the chapel, the bearer party paused as a field gun signalled the start of a one—minute silence. the service began with a tribute to the duke from the dean of windsor. we have been inspired by his unwavering loyalty to our queen, by his service to the nation and the commonwealth, by his courage, fortitude and faith. the small congregation sat in its family groups. the queen sat alone. so did prince harry. after the prayers and the commendation, a distinctive touch typical of the duke — royal marine buglers

sounded the royal navy�*s call to action stations. and finally, at the end of her husband�*s funeral, the choir sang the national anthem. seldom can its words have had greater poignancy. # god save the queen #. the family mourners departed, a widowed queen to her castle, and two brothers, william and harry, walked away together, alongside the duchess of cambridge. the duke of edinburgh is gone, but the brothers know that he would have wanted the family to move on and for differences to be healed. nicholas witchell, bbc news.

china and the us say they are committed to working together and with other countries on tackling climate change. it comes after several meetings between the us climate envoy john kerry and his chinese counterpart in shanghai last week. our energy and environment analyst roger harraben reports. china is currently the world�*s number one polluter with its massive carbon emissions from coal. but the us is most to blame historically for the emissions that are heating the atmosphere. the superpowers must work together on the climate. since the controversy over china�*s treatments over its uighur minority, us—china relations have been icy. but america�*s climate envoy john kerry has been in china, urging superpower cooperation to reduce emissions. the round table a symbol of working together. the us will announce its planned emissions reductions at a joe biden climate summit next week.

he admitted... it�*s not easy for any country. we all face this challenge. but europe has set a goal of 55% reduction. the uk has set a goal of 68% reduction. so we are evaluating right now what we ourselves can do. china�*s already the world�*s top new factor of wind turbines and solar panels. thejoint statement said finance must shift towards renewables, away from coal. environmentalists say the statement is positive, but warned that tackling climate change will need all nations to strive much harder. roger harrabin, bbc news. supporters of the jailed russian opposition activist, alexei navalny, have said he could die within days. doctors say blood tests indicate he�*s at risk of both kidney and heart failure. mr navalny is on hunger strike, because he�*s not being allowed access to his own medical team.

survived as long as it did. so this thing is incredibly fragile and flexible as it moved around the oceans. it lasted for years like that as it moved around but eventually broke into four, five pieces and then those broke up again. but the end point for some of these fragments was quite interesting because just very suddenly overnight, theyjust fragmented into millions of little tiny pieces and you can see that on the satellite data. and that process, i think, is something that needs studying a little bit more because it might tell us a little bit about how ice shelves will break up in the future. a—68 being the size of a small country made it the focus does the whole journey and the break—up and demise of an iceberg of this scale, does it give you any insight into how climate change is going to affect the ice sheets at large in antarctica?

one event on its own can't tell us that much but what we're looking at is the regularity of these events. are they becoming more frequent? and an iceberg calving is a big factor in ice loss from antarctica. so, if these iceberg calving events are becoming more frequent, then it is a really important factor that we need to be looking at and researching. while a—68 will be remembered as a social media star that was visible from space, scientists will now be turning their attention to the newest chasm on the edge of the vast ice sheet and the next giant berg to set off on its own epicjourney. victoria gill, bbc news. now for the tale of a dog, who refused to let a disability hinder his exercise regime. a car accident when he was just a year old left dexter with two injured front legs. but he�*s learned to adapt and thrive, as russell trott reports. putting his best feet forward, dexter the dog has

amazed medical experts. his owner kentee was faced with having to put him to sleep when he was just a—year—old, after he had injured his front legs in a car accident. but although he was feeling a little "ruff", she recognised something in dexter — that he was a fighter, and so she put him through surgery and therapy sessions, and effectively taught him to run on his hind legs. we didn�*t think he�*d make it. his front legs got caught underneath the wheel. i couldn�*t put another dog down without giving him a chance. he�*s become something of a celebrity in his hometown of ouray, colorado, and he�*s put a smile on the faces of his family and the locals. kentee describes dexter as goofy, sweet and smart, and she credits the dog�*s upbeat demeanour of helping them all paw through the pandemic, especially after she lost herjob. dexter, for his part, seems to be taking it all in his stride.

15, possibly 16 degrees. not quite as warm where we keep the cloud, a bit more of a breeze into the far north and west. some poor visibility to high ground as well. it looks likely as we go through the week ahead we continue with that warmer start. it will be noticeably cooler from mid week onwards and that could bring a return to some overnight frost. hello this is bbc news with ben brown. the headlines — the two russian men suspected of carrying out the salisbury nerve agent attack three years ago are being sought by police in the czech republic. a senior conservative mp warns borisjohnson he�*ll lose the support of the so—called red wall voters in former labour seats, unless he resolves the row about lobbying. a day of refelection for members of the royal family, after the queen and the nation bid farewell to the duke of edinburgh china and the us commit to working together and with other countries on tackling climate change.
