they now know why swimming can significantly improve your mood. the russian president, vladimir putin, has made his first known visit to mariupol — the ukrainian city which was captured by invading russian forces last year. russian state media says he travelled there by helicopter, and visited local residents. it's mr putin's first trip to the ukrainian territory which has been occupied by russia since the invasion was launched just over a year ago. we've received these pictures, which we understand to be mr putin in mariupol on saturday evening.

he's shown driving around in a car, and also visiting what appears to be a child ren�*s playground. and other footage shows him visiting a theatre, and talking to a group of people on a street. you can see behind him a toy which looks to be in the face of being installed. —— process. the visit came at the end of a week when the russian president was charged by the international criminal court with forcible abductions of ukrainian children. the trip to mariupol — which was unannounced, and not made public until after he had left, camer after mr putin visited crimea — the region which russia first invaded and then annexed nine years ago. i've been speaking to our diplomatic correspondentjames landale, who's in kyiv, about mr putin's tour... the timing is important. this comes just a couple of days after president putin was accused by the international criminal court of being a war criminal

for the alleged deportation of thousands of children from occupied ukraine to russia. throughout this conflict, whenever there is some kind of setback or something that has been done to russia, vladimir putin tends to respond — sometimes militarily, sometimes diplomatically, sometimes with some kind of public images, and i think that's what we're seeing here. we're seeing public images that he wishes to show after the international court made the accusation against him on friday. so, yesterday he was in crimea, today, he was overnight in mariupol, essentially producing pictures that — all these pictures are from russian state television — but images that show, you know, today, a town that is apparently being reconstructed after the devastation last year at the hands of russian artillery and russian air strikes. he's shown talking to residents who seemingly seemed to be happy with the new buildings that have been made, that are shown in the pictures, as you said, the playground there, too.

so i think this is a sense of mr putin saying, you know, the international community can say and do what it wants, but in russian—occupied crimea, it's business as usual and life is getting back to normal. that, at least, is the the imagery that he wishes to portray. so it's a bit of business as usual, a bit of defiance. but we should note these pictures are taken amidst hugely tight security. they take place, most of them in darkness. he's been driven around and there are residents seemingly standing in a group on the side of the street in the middle of that darkness. so, you know, as ever, these are carefully controlled images that we're getting. presumably, as you say, if you do it at night, that reduces the risk of a kind of unexpected encounter with a civilian who just happens to be out doing their shopping,

something like that, because it does look very quiet. what about this, this announcement on friday, the icc, presumably, again, as you say, this is partly the defiance to say, i don't care what this court we don't recognise anyway says — i'm able to move freely in ukraine. i wonder, though, if even the existence of that warrant might complicate any prospects of any future negotiated settlement because, and you'll correct me if i'm wrong about this, the icc is independent of government, so presumably, even if there were a deal that ended the war, the icc warrant would remain live. yeah, i mean, the icc warrant remains live until such time that either vladimir putin is arrested and subsequently potentially faces trial or when vladimir putin dies. you know, there's no time limit to it. so one would assume that that warrant constrains president putin's travel to the 123 member states, countries around the world that sign up to the authority and jurisdiction of the international criminal court, because if he steps foot in any of their territory, those member state governments are obliged to try and arrest him

and then make sure that he is sent to the hague for trial. that, at the moment, seems unlikely until such time, potentially — you know who knows what's going to happen in the future. it would require quite a lot of political change, i imagine, in moscow for that to happen. so in the meantime, i think mr putin is showing that in some areas, ie crimea and in mariupol, he can still travel as freely as he wishes and he can visit and show off those parts of mariupol that he wants to show are being reconstructed. because this is... when i say when i say defiance, this matters, because this city for ukraine is a symbol of its resistance from last year, and that may be one of the reasons why he's visited it. james landale in the

ukrainian capital kyiv. a little update coming out of the reuters news agency quoting south african president cyril ramaphosa because president putin is obviously travelling around a bit because he is due to arrive shortly in russia and in fact not shortly, in august in fact. he is attending the summit and questions are being asked about it in the light of the accc serving its warrant on him and putin attending the brics summit. south africa is a signatory of the international criminal court treaty and therefore is obliged to honour any warrant issued an president ramaphosa said on sunday we are as the government cognizant of our legal obligation and between now and the summit we will engage with various relevant stakeholders. make of that what you win but still, clearly a potential question. you may remember a couple of years back, slightly longer now, the president

of sedan omar basheer visited south africa when jacob of sedan omar basheer visited south africa whenjacob zuma was president and there was a lot of controversy over that visit —— president of sudan. there was some criticism of him for not arresting basheer who was subject to an icc warrant. worth pointing out that now president this year is no longer in power and as if my memory serves me correct actually in custody awaiting a trial for breaches of international law because of the war there. but we will bring you any more developments on presidents putin and indeed where is president putin now on the course of the next hour bbc news. now to the financial crisis affecting one of... some financial news — and talks are taking place in switzerland about a possible takeover of the troubled bank credit suisse. the financial times is reporting that the country's biggest bank, ubs, has offered to buy credit suisse for up to $1 billion. credit suisse had been caught up in the market uncertainty triggered by the collapse, nine days ago, of america's

silicon valley bank. it had been offered an emergency credit facility of more than 50 billion dollars by switzerland's central bank — but that had not prevented a sharp fall in its share price. our business correspondent marc ashdownjoins me. the usual caveats here. this is a fast—moving situation and either put coming out of switzerland. reporting we haven't been able to confirm it ourselves just yet but they are saying that the ubs group has offered to buy credit suisse for up to $1 billion in the interesting thing there is about an hour ago that the stock price has dropped from 80 billion credit suisse seven years ago at its peak to about 6 billion on friday and this 1 billion as the sort of book that we are talking about it is still a fraction of where shares closed on friday. that is bargain basement in banking terms. that is the source of the environment weaving at the moment. the other interesting thing here is the swiss government as we concerned over seeing the talks between regulators and ubs and credit suisse and it does appear that potentially they could step in here to bypass they could step in here to bypass the countries laws whereby under

normal circumstances if an offer came, even a distressed bank would have to be put to shareholders and have to be put to shareholders and have a vote on it and that is in the constitution. presumably notjust constitution. presumably not just credit constitution. presumably notjust credit suisse shareholders that ubs shareholders. do we want shares at risk by taking on this problem by? absolutely and as we were hearing earlier two main banks here that some will be queasy or covered with prospects of creating a super uber bank with liabilities. some of the stumbling blocks here we were discussing were potential liabilities because credit suisse has had this for many years. rich history, abound in the past four years beset by problems of reporting its issues with the financial reporting last week which triggered the whole domino effect so there will be potentially some nasties lurking about they have to deal with so they were seeking some kind of backstop from the government and they would stump up some of this money potentially but clearly $1

billion is pretty cheap and we understand it could be pushed for and it is not a deal is yet and it could be pushed for us early this evening and again nodding to importance and pace of this because of the impact it is having on the wider banking world and by the financial world.— wider banking world and by the financial world. really interesting and there are _ financial world. really interesting and there are a _ financial world. really interesting and there are a couple _ financial world. really interesting and there are a couple of - financial world. really interesting and there are a couple of things l financial world. really interesting and there are a couple of things i | and there are a couple of things i would be interested in yourjudgment on. one of this question is systemic... . we have had two banks in trouble in the united states just over a week ago and no suggestion credit suisse is connected to that and there is no obvious connection but nonetheless it has raised concerns about the health of the banking sector and the other aspect comes up with credit suisse again and one that you will know if this debate about retail banking in other words our money and money for businesses that lend and borrow and all the rest of it and borrow and invest money off our savings.

investment is the big bit stuff and big worldwide stuff in ucc credit suisse and hong kong and all the best of it. what is your perception of those? are these life concernsmuch everyone saying a week ago this is nothing like a banking crisis and this is very specific because you can say well, they were different but they're both in trouble so what is going on? to take those one pointed _ trouble so what is going on? to take those one pointed to _ trouble so what is going on? to take those one pointed to time, - trouble so what is going on? to take those one pointed to time, 2008 - trouble so what is going on? to take| those one pointed to time, 2008 was a very different than now and i think there was a feeling that every bank was advised it had been badly packaged up which every bank was exposed to... packaged up which every bank was exposed t0- - -_ exposed to... they were all in the field, yes- — exposed to... they were all in the field, yes. once _ exposed to... they were all in the field, yes. once one _ exposed to... they were all in the field, yes. once one went - exposed to... they were all in the field, yes. once one went there . exposed to... they were all in the l field, yes. once one went there was a hue field, yes. once one went there was a huge collapse _ field, yes. once one went there was a huge collapse of _ field, yes. once one went there was a huge collapse of the _ field, yes. once one went there was a huge collapse of the house - field, yes. once one went there was a huge collapse of the house of - a huge collapse of the house of cards if you like. post—2008 stronger regulations were brought in to ensure stronger balance sheets could ride out difficult weather. frankly... at the moment so they're being stretched to the limit, aren't they? incidentallyjoe biden was

talking last year about donald trump and rolling back on that silicon valley bank and first republic signature. i think if we look at credit suisse and svb very different problems they have the promise when it comes to stock shares and markets is all about... sometimes common sense goes out of the window and it is all about fear and greed and at the moment we are in a fearful know the moment we are in a fearful know the situation where as we saw stocks across the world sliding last week anything will be looking at here is how do we move forward a deal to keep credit suisse going, firstly. it is frankly one of the banks too big to fail but then how do you save a bank like that? understand some of these stocks of incentive and restructuring, 95 domestic branches in switzerland which do your standard ranking but then it is this investment side of things as well, a very rich customers that bank with them, so they will be looking at how they could break that up and of course that then impacts jobs. 50,000 workers around the world,

boris will appear before a committee of mps on wednesday — in a televised session — investigating his actions. the story is dominating the british political tv talk shows on sunday morning. our political correspondent tony bonsignore has been picking out the key details for us... rishi sunak would rather not, this week, that we were talking about parties held or not held during covid lockdowns, but that's what we are going to be talking about — this mammoth session we're expecting on wednesday afternoon. key moment, i think, for borisjohnson's future in westminster. oliver dowden again, cabinet minister, was asked about this. he was very close to borisjohnson, one of his chief lieutenants. he was asked about what to expect. this is what he had to say. i've known borisjohnson reasonably well over the years. i'm quite sure that he will put forward a robust defence of his conduct.

it will then be for the committee to make that determination and, if necessary, the house of commons to make that determination. i think that's the proper process to go through. borisjohnson's team's been out in the papers today. i've got, you know...they're talking about the dossier they're going to produce, which they say is going to clear the prime minister — might not be that simple, though, and i suspect the seven mps on the committee, privileges committee, might have other ideas. the former us president, donald trump, says he expects to be arrested on tuesday — and has called on his supporters to protest. in a post on his own social media platform, he claimed to have seen leaks from the manhattan district attorney's office — which is yet to comment. mr trump is accused of paying hush money to an alleged mistress. here's our north america correspondent david willis. four months after he announced a third run for president, donald trump could make history for a rather different reason. responding to speculation

in the american media, he took to his own platform, truth social, to level a capslock chorus of accusation against the manhattan district attorney, whose office, mr trump believes, has been leaking news of his imminent arrest. central to a long—running investigation undertaken by the da's office is the porn star known as stormy daniels. prosecutors have been looking into whether mr trump made illegal payments in order to buy her silence before the 2017 presidential election, following a brief affair. that, he denies, but it is the final five words of that social media posting that have proved particularly disconcerting to some. "protest," he writes. "take our nation back." a message chillingly similar to one he delivered shortly before the uprising at the us capitol building on six january, 2021, which saw a violent mob of trump supporters lay siege

to the seat of government. senior republicans have rallied to mr trump's defence. on twitter, the house speaker kevin mccarthy said arresting the former president would amount to what he called an outrageous abuse of power. but his democratic opponent nancy pelosi branded mr trump's social media message reckless, saying its aim was to keep himself in the news and ferment unrest amongst his supporters. mr trump's legal team say they have received no indication of their client's impending arrest, but he is facing legal battles on a number of other fronts as well. america 45th president could become the first one ever to be charged with a crime. an earthquake has struck off the coast of ecuador, killing at least 1a people. the tremor, which damaged buildings in several cities, was also felt in northern peru, where one young girl died

in the border province of tumbes when her home collapsed. the bbc world service's americas editor, leonardo rocha, reports. half of ecuador�*s provinces felt the effects of the quake, which had a magnitude of 6.8 according to the us geological survey. in the southern province of el oro was the worst affected. the emergency services said people there were still trapped inside collapsed houses. videos posted online show residents removing rubble in the search for survivors. president guillermo lasso made an appeal for calm after visiting a hospital in the southern city of machala. translation: according - to the oceanographic institute, there is no reason to worry about a tsunami. the tremor had an aftershock at 12:22 local time on a scale of 4.8 and a third tremor at 12:55 on a scale of 3.7. there are some injured people who are being treated in hospitals and there are houses destroyed both

in the province of el oro and in the province of azuay, so we have taken the decision to activate all the ministries. ecuador has a history of devastating earthquakes, including a major one in five years ago in which nearly 700 people were killed. serbia's president, has declined to sign an eu proposal to normalise relations with kosovo. aleksandar vucic said his decision was based on kosovo not being an internationally and legally recognized state. earlier the european union's top diplomatjosep borell announced an agreement between the two nations towards normalising relations. despite this belgrade has refused to recognise kosovo's independence, since it was declared 15 years ago. at only 23 years old, guillaume diop has already achieved a dream and made history against the odds. as the first black person to be promoted to the coveted

status of "etoile" dancer at the paris opera, he's now commonly regarded as one of the most exciting ballet talents of his generation. the bbc�*s daniel dadzie reports. every twirl, prance and leap is an answered prayer for the new star of the paris opera. translation: i'm still. a little bit on cloud nine. i haven't really realised that it really happened. ifeel like it was a dream but i am still very emotional and very, very happy. 23—year—old guillaume diop made the history books when he was recently named etoile dancer for the ballet. it is an honour reserved for dancers who show their excellence. only a handful have been appointed in the past 50 years.

——it�*s an honour reserved for dancers who show rare excellence. translation: there is also the weight of the institution | which is a very beautiful institution, three centuries old, so it is a form of responsibility but it is a beautiful responsibility. it's a responsibility which had never been carried by a black person until now. but guillaume's career has always challenged the status quo. translation: l was told, - "look, there are no black people at the opera." i was told that i had a big butt, flat feet, all the stereotypes about black people. guillaume is now counted among the greatest and he did it without having to go through the premier category for several years, as has always been the case. he believes it's a victory for his senegalese father who harboured doubt at a point. i think that's what's really moving for me, to see how far my father has come in relation to all these issues

and to see that today he supports me fully. he comes to all my shows. the star is hopeful that this feat will reassure parents of children like himself who want to follow this career path — perhaps they also can become stars in their own right. daniel dadzie, bbc news. now, for something a little less arduous... the popularity of wild swimming has really taken off in recent years — with both the physical and mental benefits being widely publicised. researchers in the uk say they now know why the pastime can significantly improve your mood — after studying brain function, following cold water immersion. edward sault has been to meet one group of swimmers on the isle of wight. it's 3 celsius air temperature, 7 celsius in the water, and it's time for me to get in the sea with these swimmers

from swim the wight. i have a chronic kidney and bladder issue, and back pain also — i take a lot of painkillers — and this really helps. i get a real calmness when i come here, and it's where my head, actually, it's probably the only place it really switches off. i feel really amazing - and really awake and alert. ijust love it. clears the brain of any sort of thoughts you don't need. just, like, had a mental, physical reset. swimming is something i've done all of my life, i absolutely love it. and when i get out of the water — especially this time of year — i really feel buzzing. and now researchers from bournemouth university, the university of portsmouth and university hospitals dorset say there is scientific proof. so we had participants come down to the lab who are completely naive to cold water swimming, so they weren't exactly pro athletes —

they were your average people. we got them in the scanner next to us here, then they hopped out of the scanner, very quickly got into a cold water bath that we had prepared, they were in there for about five minutes and then we got them back out, towel—dried, then back into the scanner again. it potentially opens new avenues for us, for potential treatments for some of the mental health disorders that are plaguing us at the moment. back in the water, and the chilly temperatures are not putting anybody off. i think it's a little bit like having a computer — switch it off and on again. nothing matters when you're in the water. it gives you some sort of buzz, and the colder the water, the bigger the buzz. these swimmers will be back here tomorrow for another dose of vitamin �*sea'. edward sault, bbc news, on the isle of wight.

more on that story and the rest of today's news on our website, available any time, anyplace, anywhere. hello there. for many of us, it has been a fine start to mothering sunday, some blue skies and sunshine. this was the scene earlier on in hampshire, but a scene replicated across many parts of the uk in the sunshine, we will start to see the cloud thickening a little bit, though, towards western areas of the uk and you can see that on the satellite image from this morning. this is a weather front and a weather system bringing some outbreaks of rain as well, but ahead of that many of us, dry with sunny spells. we'll keep the sunny spells for many, one or two showers perhaps possible in central and south—eastern areas as we go into the afternoon. the rain, though, moving its way into northern ireland

by the afternoon, pushing into western areas of scotland, maximum temperatures down a little bit on yesterday, but 11—14 or 15 degrees, but that will still feel quite pleasant in those sunny spells. but the rain will continue to spread north and eastward through this evening. it could be quite heavy for a time, actually, across north wales, north—western parts of england. cloud for many of us tonight and it means it is going to be relatively mild going into monday morning. temperatures to start off in the morning 7—11 there in belfast, but a wet start to the day in northern ireland. that rain will spread north and eastward, pushing into scotland into the afternoon, rain across northern parts of england will gradually ease, further showery rain spreading into the south—west. for most, though, it is going to be dry. again, some sunny spells, and temperatures up a little bit and it could reach 16 celsius across eastern areas of england. into tuesday, we are between weather systems, one will move into the north—east fairly early on in the morning and another weather system pushing in from the west as we go into wednesday. so, yes, some rain around northern and eastern areas on tuesday morning. it will clear away, though,

sunny spells then developing, but also some heavy showers and we could even see the odd rumble of thunder into the afternoon in central and eastern areas. temperatures up a little bit, though, maybe 15, 16 celsius for many. by the end of the week, we are continuing to see low pressure situated to the west, a further weather system spreading in from the atlantic, giving further showers or longer spells of rain. you may notice maybe a little bit of snow around the north—east of scotland by the end of the week, some slightly colder air will slowly move its way in here, but really for most of us it is looking dry, sorry, showery for the end of the week with temperatures about 11—15 or 16 celsius with some sunny spells. that is all from me, bye—bye.
