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. earlier i spoke to mark galeotti, author and russia crime analyst. he is a professor at ucl�*s school of slavonic & east european studies. i asked him what he thought the russians were up to in the czech republic?

it seems that the munitions which exploded in 2014 were about to be bought by a bulgarian arms dealer and then transformed to ukraine. this was the point that russia had just annexed the crimean peninsula so it looks like this was an attempt to deprive the ukrainians of munitions. the arms dealer also got caught with another chalk, which suggests a pattern. it also suggests a certain pattern of blunders. the speculation at the moment is that the gru officers had booby—trapped the munitions and they wanted it to go off until later, perhaps in ukraine. so it�*s an unfortunate mix of malice, covert operations and incompetence. these two characters, we know their faces from the aftermath of the salisbury attack.

they said they were in salisbury to look at the cathedral and its spire. what would you say then about what it says about the gru and russian intelligence generally? talk about a level of incompetence? the kremlin has basically been operating in a wartime footing since 2014. they�*re much less bothered about being named and shamed, called out and activities being identified because they feel they are in this existential 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. the russians are almost proud of these covert operations that they seem to be running in quite a few countries around the world ? they are basically operating at the same kind of tempo and aggression as at the peak of the cold war in the west, at least. there is not pride if things go wrong, but if you look at the gru itself, its culture is to be an action centred organisation. they control the russian special forces. i remember once talking

to a former gru officer. there is a sense of themselves as a match oh risk wartime operation. so for at least britain has been encouraging them to go out and break stuff. interesting to talk to you. thank you so much. 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 into the former uk prime minister david cameron�*s communications with cabinet ministers while he was working for the collapsed finance firm, greensill capital. 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 to labour's shadow cabinet office minister, rachel reeves. what we have seen this _ minister, rachel reeves. what we have seen this week _ minister, rachel reeves. what we have seen this week is _ minister, rachel reeves. what we have seen this week is that - minister, rachel reeves. what we have seen this week is that tory . have seen this week is that tory sleaze _ have seen this week is that tory sleaze is— have seen this week is that tory sleaze is back and it is bigger than ever and _ sleaze is back and it is bigger than ever and we need real change to the stored _ ever and we need real change to the stored trust — ever and we need real change to the stored trust in our democracy and in the very— stored trust in our democracy and in the very essence of public service which _ the very essence of public service which matters to so many of us and matters _ which matters to so many of us and matters to — which matters to so many of us and matters to people in our country. what _ matters to people in our country. what we — matters to people in our country. what we want to see, to have a proper— what we want to see, to have a proper enquiry, not shared by one of boris _ proper enquiry, not shared by one of borisjohnson's proper enquiry, not shared by one of boris johnson's friends, a very close — boris johnson's friends, a very close friend of the conservative party— close friend of the conservative party the — close friend of the conservative party the man doing the review. but a proper— party the man doing the review. but a proper independent enquiry which has teeth— a proper independent enquiry which has teeth and has a chance to make recommendations on how to clean this up recommendations on how to clean this up because _ recommendations on how to clean this up because this isn'tjust about

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. ongoing review, come on? {lime one. ongoing review, come on? once it is concluded. _ one. ongoing review, come on? once it is concluded, once _ one. ongoing review, come on? once it is concluded, once all _ one. ongoing review, come on? once it is concluded, once all those parliamentary enquiry is looking at this have _ parliamentary enquiry is looking at this have concluded i'm sure some of them _ this have concluded i'm sure some of them will— 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 — government will look at that. i am not saying things could not tweaked or improved but i am saying it was changed _ 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— less about who is going to who, the question is— less about who is going to who, the question is much more how did ministers — question is much more how did ministers act those conversations are done — ministers act those conversations are done that, as far as i can see, the answer— are done that, as far as i can see, the answer is _ are done that, as far as i can see, the answer is that they did not do any special— the answer is that they did not do any special favours. you the answer is that they did not do any special favours.— the answer is that they did not do any special favours. you will notice in that answer— any special favours. you will notice in that answer their _ any special favours. you will notice in that answer their that _ any special favours. you will notice

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. well, i�*ve been speaking to the royal commentator victoria murphy about the relationship between the brothers. there was a lot of discussion when it was revealed that they would not be walking shoulder to shoulder in the ceremony, but because peter phillips was not in line with them,

it actually looked like they could have been side by side. at the end of the service, they provided us with a visual that does counteract the suggestions they are not speaking and an idea that this rift has become so deep that they cannot walk side by side. we know there is a lot for them to work through, but it seems that perhaps those conversations have started. and the duke has been such a stabilising influence on the monarchy for such a long period of time. inevitably some of the papers talking about the future of the monarchy? yeah, exactly. you�*ve seen the queen in recent years, she is handed over some of her responsibilities to prince charles and other family members who step in for her. i think it�*s possible we will see a continuation of that as she turns 95 soon. the platinum jubilee is in the planning for next year. when day—to—day engagements resume, we will see her take up her duties. even in the mourning period,

she has done an audience and the idea that she is carrying on with her duties, that still does prevail. 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 the number of covid—19 deaths around the world has risen to more than three million. the latest figures show that most fatalities have been in the united states, followed by brazil, mexico and india. more than 370,000 people have now died from coronavirus in brazil. yet president bolsonaro refuses to lock down despite a sharp rise in infections. mark lowen has this report from sao paolo. every day, the faces

of despair multiply. the food lines in sao paulo�*s largest favela go on and on. with most here working in the grey economy, covid has destroyed jobs. queues have more than tripled in recent months, as the pandemic takes lives and livelihoods of brazil�*s poorest. i am very worried that if coronavirus gets worse, people in the favela will turn to crime or start looting supermarkets, says this man. when a father is starving and trying to feed his children, desperation hits. for this woman and her family, this is now their only meal of the day. she lost herjob in a manicure studio with the pandemic and they are unable to pay the rent. translation: i�*ve lost hope. we will have to live on the street or under a bridge soon.

sometimes i think i should give my children away to social services. with the pandemic, six out of ten brazilian households now lack sufficient access to food. government hand—outs last year helped, but they�*ve been reduced as money runs scarce. covid has gone from health crisis to an acute social one, too, as brazil�*s profound inequality deepens. no such concerns for the wealthiest food producers and backers of the president. it�*s corn harvest time on this man�*s 1,300 hectares. the agricultural richness of this country makes hunger hard to fathom. president bolsonaro, he says, is cutting through a corrupt establishment.

but with the president�*s anti—lockdown stance, slow vaccine purchase and more than 365,000 dead here, his critics call his handling genocidal. the president bolsonaro is not focused on killing anyone. - he wants to preserve - the liberties of the people. he wants people to get out, to get to work. - the cost of that is the second worst death toll in the world and a hospital collapse. no, it's not true because 365,000, we don't know if they only died by corona. with a public health disaster, economic woes and a divisive leader, brazil is facing a perfect storm. it urgently needs a way out from the darkness of the pandemic. but there is still no sign of it or of the hope this devastated nation craves. mark lowen, bbc news, sao paulo. doctors for the imprisoned russian opposition activist, alexei navalny, say blood tests have indicated he�*s at risk of kidney failure and could die within days.

mr navalny has been on hunger strike for 18 days, because he�*s not being allowed access to his doctors. prison officials say he�*s refused the treatment he�*s been offered. the united nations nuclear agency has confirmed that iran has started enriching uranium to higher levels than previously achieved — complicating ongoing international talks over a deal with tehran. the international atomic energy agency said the natanz plant had produced uranium of 60 % purity, bringing it closer to the level required for nuclear weapons. what was once the world�*s largest iceberg has finally broken apart. a—68, as it was known, covered an area of nearly 2,300 square miles when it broke away from antarctica in 2017. but satellite images show the "mega—berg" has now virtually gone, broken into countless small fragments that the us national ice center says are no longer worth tracking.

here�*s our science correspondent, victoria gill. a 1—billion tonne block of ice. when iceberg a—68 broke away from antarctica back in 2017, it measured more than 2,300 square miles — a quarter the size of wales. it was only by imaging it from space that scientists could actually follow the massive iceberg�*s journey as it inched its way north. at one point, it was on a direct collision course with the antarctic island of south georgia, potentially threatening to cut off vast populations of penguins and seals. but it was off that coast in the open ocean swell that the world�*s largest iceberg broke apart and now that it�*s officially been declared deceased, the scientists who�*ve been following itsjourney so they are surprised it 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 of global media attention. but the breaking away, or calving, of these giant icebergs is a natural part of the ebb and flow of the dynamic ice shelf. 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. one of the largest exhibitions of original art works to open in the uk as lockdown restrictions are eased is from a british woman known as �*the felt lady�*. lucy sparrow�*s fabric fantasies have gathered fans worldwide and her latest exhibition is a felt pharmacy. alex stanger has been to visit the national felt service this is a chemist like no other. all 15,000 items stocked on these

shelves are made of felt, created to raise a smile rather than curing illness. since herfirst uk exhibition in 2014, lucy sparrrow�*s felt—made shops have popped up in the states and china. all the items on the shelves here are for sale, but it will probably cost you a little bit more than your usual trip to the chemist as they are all art collecta bles. they were made at lucy�*s new headquarters in suffolk. welcome to felt hq. lucy and her team have been working from this old ambulance station for the last year on this exhibition, which will be her first in the uk in five years. actually, i�*m nervous about doing a show back in the uk because us brits are so reserved. you do a show in america and i�*m not evenjoking, people start screaming, crying, laughing. the original opening of the show had to be postponed because of lockdown restrictions which,

according to lucy, has made the exhibition all the more relevant. all my work is focused around presenting the everyday in a way that makes us notice it more. when the pandemic was starting, it was sort of chemists and food shops that were the only places you could go. they became so central to everything that we were going through. yes, i�*d like to think this is the way i reacted to the pandemic by making and immortalising the chemist out of felt. even if there is a rush on paracetamol, don�*t worry, felt favourites will be restocked until the exhibition closes on may 8th. now it�*s time for a look at the weather with louise lear. hello, there. it has been a quiet weekend so far and we are going to continue along that vein. once again, there was a beautiful start for many. a light frost but some blue sky and sunshine. there is a little bit of patchy

rain though around and that has been affecting western scotland, northern ireland, just pushing into the isle of man as well. with a little bit more in the way of cloud developing as we go through the afternoon, perhaps along west facing coasts. the best of the sunshine certainly is going to be across much of england and wales. and with light winds coming from a southerly direction, it will feel a little bit warmer than it did yesterday. we could see highs as we go through the afternoon, peaking at 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.
