the government of switzerland says that the country's biggest bank, ubs, has taken over its troubled rival, credit suisse, in an emergency measure designed to protect the swiss economy. 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 by switzerland's central bank, but that had not prevented a sharp fall in its share price. here's the swiss president, alain berset, speaking at a press conference a short time ago. on conference a short time a-o. on conference a short time am. friday, on conference a short time a-o. friday, the liquidity s it on friday, the liquidity showed that it was_ on friday, the liquidity showed that it was no— on friday, the liquidity showed that it was no longer possible to restore the necessary confidence, and the swift _ the necessary confidence, and the swift and — the necessary confidence, and the swift and stabilising solution was absolutely necessary. this solution is the _ absolutely necessary. this solution is the takeover of credit suisse by

credit suisse. you heard the swiss president calling it the best solution. frankly, the only solution. frankly, the only solution. but credit suisse's shares were in freefall. there's been a lack of confidence in the bank for quite some time. now ubs will take over credit suisse with, i have to say, a certain amount of reluctance. behind that is $100 billion liquidity from the swiss national bank to make sure that all the problem that ubs swallows as it swallows credit suisse don't make ubs, which will now be the last big bank standing in switzerland, which it won't have too many problems itself by going ahead with this takeover. now, we are the swiss president when he said it was very important for the economy and his citizens. just about every swiss

company has an account, has its investment in either one of these banks in addition to credit suisse being a globally important bank. any further turmoil would've caused more knock—on effects for the global financial sector, and of course, that was a huge worry. everyone around the world has been watching these discussions today.— around the world has been watching these discussions today. imogen, can ou talk to these discussions today. imogen, can you talk to us — these discussions today. imogen, can you talk to us a _ these discussions today. imogen, can you talk to us a little _ these discussions today. imogen, can you talk to us a little bit _ these discussions today. imogen, can you talk to us a little bit about - you talk to us a little bit about the relative size of these two banks? how easy will it be for ubs to take over credit suisse? i banks? how easy will it be for ubs to take over credit suisse?- to take over credit suisse? i have to take over credit suisse? i have to sa , to take over credit suisse? i have to say. it's _ to take over credit suisse? i have to say. it's early _ to take over credit suisse? i have to say, it's early days, _ to take over credit suisse? i have to say, it's early days, but - to take over credit suisse? i have to say, it's early days, but i - to take over credit suisse? i have to say, it's early days, but i don't| to say, it's early days, but i don't think it's going to be easy. ubs is the bigger of the two, but both of them are already huge. if you look in switzerland, both of them have at least one branch. in every town.

we're looking certainly at probably thousands ofjob losses because what is the point of having two branches of the same bank in a small town or village? that's clearly not going to happen. but i think if you look globally, there's going to be a lot of scrutiny now. these are both globally important banks. now it will bejust ubs. globally important banks. now it will be just ubs. what is going to happen with the investment sector? what is going to happen with the wealth management sector? further down the line, given that this meltdown seems to take the regulators by surprise, what does it mean for switzerland's reputation for being a safe place to invest money? this is a pastorfee, frankly, for the swiss financial sector. . ~' , ., , . frankly, for the swiss financial sector. ., ,, , . ., sector. thank you very much for takin: us sector. thank you very much for taking us through _ sector. thank you very much for taking us through that. - sector. thank you very much for

"we need to start getting to know each other better," mr putin said.

"we pray for you," one woman said. "finally, you are here. we have waited for you so long." mr putin was invited inside to see one of their homes, seemingly a new apartment — the aim, it would appear, to show a city being rebuilt after last year's devastation. for this is what mariupol looked like last year after three months of russian bombardment, during which ukrainian fighters held out here at the azovstal steel plant — their long defence a symbol of ukrainian resilience. it was here, too, where russian forces bombed a maternity hospital — an early alleged war crime — along with a theatre where hundreds of civilians were sheltering and died. here in kyiv, the mayor of mariupol told me how he felt seeing mr putin in his city.

translation: like all ukrainians, like all mariupol residents, - i feel that today, a war criminal whose name is vladimir putin visited the scene of a crime he committed for several months — destroying the city of mariupol. the only city russian aviation is carpet bombing is mariupol. this is what parts of mariupol actually look like — contemporary images from local residents showing still—ruined tower blocks. long lines of people queuing for food. all in stark contrast to the reconstruction that mr putin did get to see, including a theatre that had been rebuilt. under bright streetlights, he was also shown a playground, only days after he was accused by international prosecutors of illegally deporting thousands of children from occupied parts of ukraine to russia.

james landale, bbc news, kyiv. on friday, the international criminal court issued an arrest warrant for vladimir putin. joining me is the prosecutor general of ukraine, andriy kostin. thank you for coming into the studio. before we get to the case at the international criminal court, can you first told us your reaction? i think it's the same reaction and it's widely discussed in ukraine that the perpetrator returned to the crime scene to real life —— relive the crimes he has committed. we always remember the maternity theatre and the theatre and thousand

killed by russian militaries on the ground and by bombing, which was months every day. i think it's just the case of putin who returned to the case of putin who returned to the crime scene. the international criminal court _ the crime scene. the international criminal court has _ the crime scene. the international criminal court has mentioned - the crime scene. the international criminal court has mentioned that| criminal court has mentioned that there could be more cases attached to mr putin's arrest warrant on top of the case of the deported ukrainian children who had been deported to russia. what evidence can't ukraine provide for that and will those cases perhaps focus on what has taken place in mariupol? mariupol is one of the cases under discussion. not only now, but from the very first days. we have actually a substantial number of cases where he discussed the

operation. what is important for this arrest warrant is icc completely respect the work of ukrainian law enforcement agencies and prosecutors and courts, who can prosecute most of the crimes internally. having indicted and issued arrest warrant against putin, the icc showed it plays a complementary role because of putin and the other two people have personal immunity in ukraine. this is also symbolic. we have prioritised some cases in order to reach our goals in more speedy manner. ~ . , ., reach our goals in more speedy manner. . . ,., manner. which cases are your riori manner. which cases are your priority at _ manner. which cases are your priority at the _ manner. which cases are your priority at the moment? - manner. which cases are your priority at the moment? the i manner. which cases are your. priority at the moment? the case where putin _ priority at the moment? the case where putin was _ priority at the moment? the case where putin was invited _ priority at the moment? the case where putin was invited was - priority at the moment? the case where putin was invited was our. where putin was invited was our

priority. at the moment, we have others. i can't disclose this information, but this is really only the first step. 0thers information, but this is really only the first step. others will follow not only with relation to putin, but also to other perpetrators. ukraine still has no access to the crime scene and we need wide support and wide cooperation from different governments, law enforcement agencies and intelligence agencies in order to build these cases. irate in order to build these cases. we should say that you and your colleagues are working in a time of conflict. how does that change the nature of your work and what challenges does that place on you? the challenge i already mentioned is the most important one since we have no access to the territory.

therefore, we are looking for modern it solution and very wide range of intelligence, especially open source information, satellite imagery, etc. in order to collect evidence is for the crimes which are committed every day — for instance, destroying of critical civil infrastructure by missiles and drones. we can of course fix the incident. we can make a lot of forensic researches, but is important to us to find exactly who gave the order and who committed these specific missile attacks. for this, once again, we need not only intelligence information, but wide international cooperation and tomorrow, we will have a chance once again to discuss this.— again to discuss this. russia has said it doesn't _ again to discuss this. russia has said it doesn't recognise - again to discuss this. russia has said it doesn't recognise the - again to discuss this. russia has i said it doesn't recognise the arrest warrant in place against vladimir

putin. how confident are you that he one day will appear in court? you know, one day will appear in court? you know. it's — one day will appear in court? wm, know, it's important for us as lawyers to prepare everything necessary in case he will appear, he will be convicted and will spend the last of his life in jail. we all understand that the number of crimes committed by putin's regime is enormous. 0urwork committed by putin's regime is enormous. our work is to prepare all legal grounds for him to be — and not only for him, but for his surrounding — to be held accountable and after a fair trial, to be convicted and spend life in jail. just briefly, how many hours does it take to prepare just one case of a

to the growing threat the planet faces. and as our climate editor, justin rowlatt, has been discovering, there's already clear evidence of dramatic change in the surrounding alpine environment. dave searle is claiming an ice face high in the alps. it's, like, super exciting, and there's so much happening and going on. his safety depends on the strength of the ice. you're listening for a good thunk, and making sure that the ice axe isn't wobbly. but the ice in the highest mountains of europe and the world is changing. for me, it's been quite shocking how fast it's been developing. the winters are just much more mild. we're getting rain higher up the mountain. the greenhouse gases emitted since the industrial revolution have already raised global temperatures by a little over1 degrees, but the effects are even

greater in the alps. the temperature up here is rising by about twice the global average. it has already increased by 2 celsius, and it is having a devastating effect on the snow and ice up here. at an observatory 3.5 km up this swiss mountain, they've been monitoring the change in alpine climates for decades. 30 years ago, it never rained, but now there is, and summer, very often, there is rain, even up here at 3500 metres. wow. yep. last year, the ice melt heat a new record. the glaciers of the alps lost 6% of their total volume. the very best forecast - for the future of our alpine glaciers is that we can save about one third i of the ice falling. this is the best case. in the worst case, we'rel going to lose everything.

look how the glacier below the weather station is expected to retreat over the next few decades and that worst—case scenario. so, what does dr huss think the message from the un scientists should be? action is now urgently needed. for the glaciers, we see - the effects of climate change. this is illustrating how| urgent it is to act now. this landscape appears eternal — literally frozen in time. but without dramatic reductions in greenhouse gas emissions, the ice up here at the top of europe will be lost forever. justin rowlatt, bbc news, in the swiss alps. a charity that specialises in helping british muslims with financial problems, says it's been overwhelmed by people needing assistance. the national zakat foundation has received up to two thousand applications a month for crisis grants — double the figure it was getting last year. michael buchanan reports.

for a few hours a day, two—year—old ali has his house and his mother to himself, before his four siblings return from school. berlin is separated from the children's father. the family live off £236 a week. it's not enough, and she's built up large debts trying to raise five children alone. they don't understand. they will ask me everything, "can you buy this, can you buy that?" they have to ask me for something, they want it. sometimes i say, "ah, tomorrow, we will do tomorrow," and they forget sometimes. muslim communities in britain are disproportionally poorer than the rest of the country. poverty levels are particularly high among people of bangladeshi, pakistani and black african heritage. this charity distributes zakat — money donated by muslims to help fellow muslims in need. demand for its hardship fund is greater than ever —

some months, they're seeing over 2,000 applications. zakat, especially, has always been seen in the muslim psyche in britain, certainly, as for people who are homeless, foodless, in some far—off land. and just to overcome that, some people say, "ok, the community is here for you, zakat is yours, as well," that's difficult for us. we're seeing a record number of people accessing support. i at the east london mosque, what started as a response to the pandemic has become an ongoing lifeline. a lot of our families, - they live in very overcrowded housing situations. it is a community that has always | been an poverty, that has reallyl struggled with employment. and it doesn't really help, the fact that things - are really expensive. for this woman, her rent�*s the big problem — it's increased by £200 to 1500 per month.

translation: i have two children who i need - to feed, but i can't work. it's so cold and chilly out there and i have no alternative but to come here. there's a huge stigma in muslim communities around asking for help from charities. but when bills are rising this rapidly, faith and family can only go so far. michael buchanan, bbc news. the former uk prime minister boris johnson is to publish evidence in his defence — before he faces questions from mps over whether he misled parliament about parties held in downing street during the covid lockdown. his own government brought in the laws, banning many gatherings at the time — but mrjohnson was fined for attending drinks parties. misleading parliament is seen by other mps in the uk as a serious breach of the parliamentary rules. borisjohnson will appear before a committee of mps on wednesday — in a televised session investigating his actions. 0ur political correspondent,

ione wellsjoins me now. ione wells, joins me now. tell us more about what we're going to be learning in wednesday's session. it's expected that tomorrow, boris johnson will submit to this committee of mps. his offence that has been put together and those advising him as well —— defence. these might include messages from some of his officials advising him of time which you might argue shows that he was advised that no rules were broken. therefore, he has always maintained throughout the process that he didn't willfully mislead other mps in parliament. it's expected that if he doesn't submit this defence, they will publish that, so we will be able to see what his case is. it's wednesday that there will be the real day of

action on this matter because that's when he faces a televised hearing. he will be grilled by mps on this panels, working out whether he misled parliament. ithink panels, working out whether he misled parliament. i think that will get a lot of attention both from his supporters and his critics.— supporters and his critics. we've been talking _ supporters and his critics. we've been talking about _ supporters and his critics. we've been talking about partygate - supporters and his critics. we've been talking about partygate forj been talking about partygate for quite some time. viewers might be forgiven for thinking why this is still an issue. what really is going to be looked at that hasn't been discussed before and how could it go for borisjohnson? it’s discussed before and how could it go for boris johnson?— for boris johnson? it's a good ruestion for boris johnson? it's a good question and _ for boris johnson? it's a good question and the _ for boris johnson? it's a good question and the committee i j for boris johnson? it's a good - question and the committee i have been clear they are not reopening investigation into partygate itself. the former top civil servant into these parties that took place during covid restrictions. it is a still big issue because the key question remains whether or not borisjohnson

misled fellow mps. if he is found to have misled parliament, he could face some kind of punishment that mps would then get to vote on. this could include at the most extreme a suspension from parliament. if that was ten days or more, he could even face what's known as a recall petition, meaning he could face a by—election in his seat. this is all hypothetical, but that is a concern from him and his political career, but also the conservative party that he is part of because they probably do not want to be facing any prospect of a by—election. just do not want to be facing any prospect of a by-election. just very briefl , prospect of a by-election. just very briefly. what _ prospect of a by-election. just very briefly, what sense _ prospect of a by-election. just very briefly, what sense do _ prospect of a by-election. just very briefly, what sense do you - prospect of a by-election. just very briefly, what sense do you have - briefly, what sense do you have about boris johnson's briefly, what sense do you have about borisjohnson's popularity within his own party? because he still have a lot of support?- still have a lot of support? well, he is still a _ still have a lot of support? well, he is still a very _ still have a lot of support? well, he is still a very divisive - still have a lot of support? well, he is still a very divisive figure . he is still a very divisive figure within the party, and there are very vocal defenders, people like former kim cabinet ministers like jacob

rees—mogg and nadine dorries. i think there are some vocal supporters among some mps, but also some within the party. there are also some very fierce credit in the conservative party that feel like some of the scandals he got involved in and other issues when he was prime minister have meant that the party's been tainted as a result. i think he is still very much dividing the conservative party. some of those factions make about —— may come out on wednesday. you those factions make about -- may come out on wednesday. you have a bus week come out on wednesday. you have a busy week ahead, _ come out on wednesday. you have a busy week ahead, lone. _ come out on wednesday. you have a busy week ahead, lone. thank - come out on wednesday. you have a busy week ahead, lone. thank you. | the leader of the liberal democrats, sir ed davey, says his party would seek a closer economic relationship with europe if it was in government, in order to �*fix britain's trade'. speaking at the party's spring conference, he also pledged to fix the nhs, reform social care, and tackle

the cost of living crisis. yes, we need immediate solutions to the cost—of—living crisis engulfing so many families and pensioners, like using a proper windfall tax to cut energy bills. but we need far more than that, too. the historicjohn lewis chain of department stores is looking into selling a minority stake of the business for the first time. the high street retailer, which first opened in 1864, is currently jointly owned by its staff. but the bbc understands the company's chair, sharon white, is looking into changing the business model in order to attract new investment. it's believed the plan is in its very early stages and no agreement has been made. john lewis says staff will be the first to hear about any changes. now on bbc news, the weather with chris fawkes. hello again. this month has already been quite a wet month. there are quite a few areas across the uk that have already seen more than the march average rainfall, even though we're nowhere near the month's end.

the wettest place, shoeburyness, where we've had nearly 1.5 times as much rainfall as we'd see in an average march, and there's loads more rain to come as well. over the next five days, the wettest weather, the largest rainfall totals, would be across western and particularly north western areas of the country. i suspect by the end of the month, there'll be some areas that have seen more than twice the average march rainfall. now, today's not been a bad day. we have seen some sunshine, although the cloud thickened up with these weather fronts approaching from the west, bringing some rain to end the day. and, indeed, that rain's still going to be with us overnight tonight, so a wet night for northern ireland, northern england and scotland. further southwards, might see a bit of drizzle falling from the cloud that works across the rest of england and wales. it's a mild night — temperatures 6—7 for most, cold air just about still hanging on in shetland, where it should be another bright start to the day here, but otherwise, a lot of cloud around. some heavy rain moving from northern ireland across scotland during the day and another batch of rain for wales and western areas of england through the afternoon. you might find a few brighter spells across eastern england and generally not much in the way of rain expected

in eastern england. temperatures could reach about 16. now, we've got more heavy rain for scotland on tuesday. elsewhere, it's a day of sunshine and heavy showers, those showers with thunder mixed in with them. the next band of rain quickly moves into northern ireland late in the day, so we've got more rain on the way. that rain through tuesday night pushes its way northwards and eastwards across scotland, where it's going to be quite slow—moving. and then a windy day on the cards for wednesday — a day of sunshine, blustery showers, hail and thunder mixed in with these, and some of the showers across western areas could merge together to give some longer spells of rain. all the while, it'll be windy with gusts perhaps 40, 50, even 60 mph across northwestern areas. it stays windy through thursday and again, it's another very unsettled day. showers will be widespread — again, some of them with hail and thunder, but there will be a bit of sunshine between those heavy downpours. temperatures for the most part still into double figures, but it's starting to get a little bit cooler in scotland — might see a bit of snow returning to some of the highest scottish hills.

then, through friday, and the weekend it stays unsettled with more rain on the way. those rainfall totals continue to mount up.
