the us and un renewed warnings about a ground assault in gaza. vandalism arrests in russia as voters spoil their ballots on day two of the country's presidential elections. vladimir putin is almost certain to win a further six years — his only serious rivals are dead, in prison or in exile. leading doctors warn against unnecessary use of blood sugar monitors for people who don't have diabetes. let's return to our top story — and vaughan gething has been announced as the winner of the welsh labour leadership election. the outgoing first minister, mark drakeford, will step down from the post next week. vaughan gething,

wales�* economy minister and a former solicitor, was born in zambia and will become wales�* and europe's first black leader. in his acceptance speech after being voted as the new welsh labour leader, he highlighted the historic nature of his win. thank you to the staff, the team, the procedures committee. mark was the right leader at the right time in the epidemic. —— in the pandemic. but too little said

about the heart that went into it. the deep and unwavering devotion fairness, two wheels as a community. as a fabric and families. at the hardest of times he made as feel safer, he made us feel proud. and he always made everyone aware that we each have a part to play in our national story. there is no greater legacy than that. thank you, mark, for everything that you have done for everything that you have done for our party, and more importantly, for our party, and more importantly, for our party, and more importantly, for our country. and, jeremy, we have been cabinet colleagues, political allies, and once the dust settles again, i hope, firm friends. i know thatjeremy�*s

candidacy has given new confidence to welsh boys and girls who might otherwise have thought very differently about public life here in wales. people won't accept me, or it isjust not in wales. people won't accept me, or it is just not for me. those kind of thoughts are ones that you have helped to banish from homes across wales. jeremy, the story that you have told, the example you have already set, and the idea is that you promoted in this campaign, have already helped to change wheels for the better. i look forward to working with you and stop thank you to you and to your campaign team for the contest. i also need to recognise my own

excellent campaign team that came together quickly and at short notice. they leftjobs, cancelled notice. they left jobs, cancelled holidays, notice. they leftjobs, cancelled holidays, some even came out of retirement. all of them dedicated so much, from which i am so grateful. my much, from which i am so grateful. my campaign co—chairs, thank you for your support, my campaign co—chairs, thank you for yoursupport, guidance, my campaign co—chairs, thank you for your support, guidance, advice and leadership of our team. last, but by no means least, thanks to welsh labour and trade union members who have taken part in this contest. as a welsh labour activist for nearly three decades i am proud to have received support from members of our party and movement across wales. and as a former trade union steward and employment lawyer and welsh tuc

president, receiving support from six of our biggest trade unions was an honour. today, we turn a page in the book of our nation's history. a history that we write together. notjust because i have the honour of becoming the first black leader in any european country, but because a generational dial has jumped, too. devolution is not something i have had to get used to, or to apologise for. devolution, welsh solutions to welsh problems and opportunities, is in my blood. it is what i have always known through my adult political life. that's the same for a growing number of our citizens. i want us to use this moment as a starting point for a more confident march into the future. a march into the future on behalf of a generation that too often is being asked to pick up the pieces and the bill for those who came before them.

in wales it often takes the worst times to get the best out of us. in adversity, you can't match us. we will be there. fighting tooth and nail for the impossible to happen, for the underdog, for the oppressed. when your back is against the wall, you want welsh people by your side. we will be there. no coincidence nhs has its roots in wales. no coincidence the solidarity shown in the miners�* strike. no concerns that welsh people are working around the world to build peace and heal division. in times of strife, unites, we organise, we succeed. when we see adversity, we act. but what about when it comes to ambition, to raising our sites? not

just knuckling down, but rising up. we can do more. wales has every right to be confident. of course we are still here. we have always been here, we always will be here. the question today is, what is next? can we answer the call of a generation in waiting to deliver the wales that they want? a wales that they want to be proud of, a wales we can all be proud of. i believe we can. i have set up building blocks of how we will get there. for a healthy nation, for a place called home, for a green prosperity, for ambitious futures and for a stronger wales. and i note that we can win the next

general election. we can win so that young people no longerfeel weighed down by a uk government that has no interest in the future. we can win so that neighbours are not pitted against each other, exhausted by culture wars. we can win so that wales can take its place at the frontier of a green jobs wales can take its place at the frontier of a greenjobs revolution, that fuels new ambition and expands horizons. we can�*t win if we stand together. linking arms to defeat the narrow forces of the vision. that seek to make a one nation turned cold. that only happens if we sweep the tories out of office and sent keir starmer into number ten. we can win and we must win. none of us should underestimate the hard work ahead, and is a work that we must do, and we cannot do it alone. it took a team of 3 million to get through the pandemic. it will take a

team of 3 million to recoverfrom it. it will take a team of 3 million to win a brighter future for wales. i offer a hand of friendship and a listening ear to anyone in senned, anyone in wales, who shares my ambition for our country and wants to get serious about the challenges that we face. i know that delivering on what people need requires listening, not lecturing. restoring trust, recovering dignity, and the rate we speak to one another may seem an impossible task in the face of a rising tide of nasty populism thatis of a rising tide of nasty populism that is hungry for a disunited wales. but welsh labour is in the business of making the impossible possible. across the world art movement has never backed down from a challenge. our movements, from the birth of trade unions, through 100 years of labour in wales, hasjean

—— has dares not only to dream but delivered, a safety net for those who are on of time through no fault of their own, nhs, who are on of time through no fault of theirown, nhs, minimum who are on of time through no fault of their own, nhs, minimum wage, rights at work, so much more. none of it imaginable before our movements called for it, organise for it, and delivered it. we did those things together. i know that we can�*t meet the challenges of today. and we can win that better, fairer future that we all deserve. we know what will be tough, but we know that we can only get there together. friends, let us get there together. friends, let us get to work. thank you all very much. that was vaughan gething there, set to become welsh first minister.

some pushback from plaid cymru. more on that on bbc news website. sainsbury�*s says it will not be able to fulfil the "vast majority" of online deliveries today. customers have been contacting the supermarket on social media to report issues with their online orders. sainsbury�*s says it was caused by an overnight software update. tesco says it is also working to fix a technical hiccup that meant it had to cancel some online orders also due for delivery today.

with more on this, sean dilleyjoins us. i have been following it on social media. it will be a busyjourney to the shops. why�*s that? in the of sainsbury�*s, there was some kind of overnight update to the software. there was an error or a glitch. that meant the vast majority of orders that were scheduled for today are not being fulfilled. an additional difficulty that sainsbury were having, because one imagines that as a logistical nightmare, they have been unable to directly contact those affected customers. what they have said is that they have had contactless card payment issues and some of the app store. they said they are chip and pin and cash is working in stores. bbc has visited some stores in london. 0ne

working in stores. bbc has visited some stores in london. one of those, the chip and pin was not working, it that was coincidence, but there are reports of fat around the country. for scenes with customers, the chances are if you had a delivery schedule for today, you will not get it, but what you will get, along with an apology from the chief executive is a voucher. i have always said if you can get your groceries, treat yourself to a takeaway. 0therfoods your groceries, treat yourself to a takeaway. other foods are available. any sense of fairness might be resolved for customers? sainsbury�*s are seeing their online ordering system is up and running now and there is no issue with ordering for tomorrow and the next day. it very much looks like it is people who had slots booked for today. but as i am sure we are about today. but as i am sure we are about to get onto, it is not only seems customers who have had tales of woe

when it comes to those of supermarket delivery is not showing up supermarket delivery is not showing up today, but far fewer with a supermarket you are about to mention. that brings us onto tesco. it is not just tell us more. people start hearing yesterday about fast food chain mcdonald�*s having cyber issues. they heed about sainsbury�*s. and now with tesco, anybodyjoins sainsbury�*s. and now with tesco, anybody joins the sainsbury�*s. and now with tesco, anybodyjoins the dots. the problem is it can make no sense. in this case that bizarre analogy that came from nowhere has some relevance. the bbc understands that the issues that tesco has been experiencing, that means they have been delivering to the majority of their customers, but some have not had their deliveries, they are unconnected, the bbc understands, to that sainsbury�*s issues. i am sure there will be it people scratching their heads at tesco and sainsbury�*s today thinking, what on earth has gone

wrong with the system? maybe they have got those answers, may they are still looking for them. while some tesco customers may not receive some of their deliveries later today, the issues that were causing the tesco issues have now been resolved. it is one of those things, it is easy to pass this off as you can just nip out to the supermarket, or get a takeaway. but there are some people who are relying on those deliveries, people who have may be there at sunday roast for those who are traditional enough, not arriving tomorrow. 0n the bbc website, check this out, there is a disabled customer who says that for them, the idea of going into a shop and shopping in the traditional way is a bit of a nightmare, and there are a lot of families with children who will have those issues. we will keep you up—to—date. we will bring you

up—to—date as this proceeds. but it does look like armageddon is not here, your shopping will start to arrive with sainsbury�*s and beyond from tomorrow. and as far as tesco is concerned, issue resolved, normal business from tomorrow, hopefully. thank you. one of the busiest motorways in the uk, the m25, has been closed for the first time in its history. among those affected by the disruption are people going to gatwick and heathrow airports, as well as the channel ports. marc ashdown reports. up up to 6000 vehicles an hour usually pass through here. for the first time, ourscheduled pass through here. for the first time, our scheduled closure of an entire section. it has the potential to be absolutely chaotic, good looks. if you can _ absolutely chaotic, good looks. if you can avoid travelling, please do so. this morning the so. this mornin- the advice to avoid the

this morning the advice to avoid the area seem to have got through. this is normally what it is like on a monday on tuesday, rush hour. saturdays it is normally quieter. you can see the increase in traffic, but it is not as bad as we expected it to be. this five mile stretch between junction ten and junction 11 is closed to all traffic until six o�*clock on monday. there is a designated diversion which anyone who actually has to travel is strongly advised to stick to. the m25 is one of the busiest and most crucial motorways, linking london �*s the reports and channel ports on the coast. as of 200,000 journeys are made on this section every day. john is are now being diverted on to much smaller roads. this weekend comes after a year of roadworks which have already hit trade and businesses. there is no way i will be able to get in and out, it will be

dreadlocked, the diversion is coming past our front door. it is not going to be feasible for me. the £300 million project aims to improve one of the most notorious sections for congestion and accidents. it will not be finished until the middle of next year. for more full weekend closures are planned between now and september. leading doctors are warning that blood sugar monitors being promoted across social media are unnecessary for people who don�*t have diabetes, and in the most extreme cases could put some at risk of eating disorders. the devices are part of a trend for personalised nutrition, spearheaded by companies like zoe. our health and disinformation reporter rachel schraer has been getting the details. blood glucose monitors like these have been used by people with diabetes for years. now, zoe is trying to bring them to people without the condition, and you will find their trademark yellow logo everywhere — on social media, on bus stops, even branded yoghurt drinks

in your local supermarket. the health technology company is just one of several selling the promise of personalised diet advice, tailored to your individual body. zoe says this can help you lose weight and get healthier, but dieticians and doctors have told the bbc they are concerned these types of programmes have elements that are not based on strong evidence. they could even be harmfulfor some people. so, how does market leader zoe�*s programme work? customers are given a gadget called a continuous glucose monitor to track what their blood sugar is doing. they�*re asked to wear it for two weeks and log everything they�*re eating. people doing the zoe programme are also asked to eat a special cookie, high in fat and sugar, and then do a blood test to see how much of the fat and sugar ends up in their blood. and they send a stool sample to zoe to test the bacteria in their gut. blood sugar monitoring isn�*t the only thing zoe focuses on, but it�*s probably the thing

that is gained the most attention. they are recommended for many people with diabetes, but what about for people without the condition? i�*ve spoken to dr partha kar, the nhs�*s national diabetes adviser. there is huge evidence that use of continuous glucose monitors in people do have have diabetes — type one diabetes, type two diabetes. the evidence base beyond that for people without diabetes is extremely sketchy, if not poor. you really run into the risk of creating a degree of eating disorder, so to speak — which we do see in some people — so i think it is important to bear that in mind, and that is a worry. eating disorders are complex mental health conditions and there is no evidence there is a widespread reaction to the programme. zoe says that coaches are trained to support people through issues like food anxiety and they take their customers�* well—being seriously. they say that coaches can refer people onto other services if they feel it�*s necessary. they also told us that...

i�*ve spoken to zoe�*s chief scientist, sarah berry. we're building a good picture. yes, we don't have all of the evidence, but i think it would actually be irresponsible to wait 40 years until we see these hard clinical evidences, especially given the food landscape we now live in, where there is an excess of the types of food that we know cause these big increases in circulating blood glucose and these big dips. diet specialists have told the bbc that the zoe programme contains plenty of sensible advice, like eating more whole foods and plants, but it�*s hard to separate out the effective meal plans, online support and coaching from their bolder claims that zoe tests can predict your health and personalise your diets. these are less evidence—based, researchers say, and make it harder to know which bits of the programme should be recommended to the general population. more than 75 billion blocks

of lego are sold every year but notjust for kids it seems. artist nathan sawaya has decided to use them to create large pieces of art and they�*re now on display at an immersive exhibition in east london. nathan has been telling us what inspired him. i use lego bricks for two reasons. one, i think aesthetically there�*s something there. i like the distinct lines, the sharp corners on all those rectangular pieces. when you see my work up close, you�*re going to see all these right angles, these blocks and squares and rectangles, but then you back away from it and all those sharp corners, they blend into curves. and i think that�*s the magic of using lego bricks. i�*m nathan sawaya, and i�*m an artist who uses lego bricks. there are no limits to what can be built with this toy. so it�*s great as a toy that�*s also

great as an art medium. for that very same reason, i can use it to create whatever i can imagine. i think lego is one of those unique products that really spans the test of time. and i feel it�*s a great way to talk to, say, younger kids. how do you talk to a five—year—old about the venus de milo? well, maybe if it�*s made out of a medium they�*re familiar with, like lego bricks, it kind of opens the door to that conversation. a life—sized human form is going to take me up to two to three weeks to complete, and i�*m using anywhere from 15,000 to 25,000 lego bricks. so in this exhibition, there�*s over 100 works of art, and it really covers the breadth of my career. you�*ll see some works that are very simplistic from early on, and as you travel through the exhibition, you�*ll see more works that are more complex as i grew as an artist. and there�*s even a dinosaur skeleton that�*s over 20 feet long, so there�*s a lot to see. there�*s probably something for the whole family. as an artist, i think my role

is to inspire others. and so when folks walk through the exhibition, they�*re inspired to explore their own creativity. so we have a place at the end of the exhibition where kids can dive into some lego bricks and create their own creations. the exhibition will be here for a few months at the boiler house. very excited to see what the people of london think of it. sir lenny henry has fronted comic relief for the final time, nearly four decades after he co—founded the charity. last night�*s show raised more than £40 million towards tackling poverty in the uk and around the world. £1 , 602,539,154. sir lenny henry revealing the total amount raised by comic relief over the past 39 years that

he�*s been at the helm — and that�*s before including what was raised last night. i�*m actually speechless. thank you all so much. long may it continue. and i thank you with every ventricle of my heart. never give up caring. emcee: sir lenny henry! the night began with tributes to the comedy legend. tonight being the last time lenny will host the show, ladies and gentlemen. all: aw. it�*s been an amazing tour of duty. i've got to say, you are 100% totally and utterly — am i right here when i say — he's irreplaceable. cheering and applause. # i can't get enough of your love i can't get enough of your love # the public also had their say as they voted this their favourite lenny moment. # i�*m just len. # chatting on the phone with james corden.

# what will take for me to leave these shows? # retire the nose, face destiny? sorry about that and, just to be clear, i had that planned way before gosling did it at the oscars. laughter. well, i�*m backstage at comic relief — you can hear the show behind me. there�*s a lot of excitement but this year, a sense of sadness as well that it is sir lenny henry�*s very last time hosting the show. and through it all, the central message wasn�*t lost — raising funds to support thousands of small charities in the uk and around the world. sir lenny will continue his work behind the camera as life president of comic relief. all chant: lenny! now it�*s time for a look at the weather with darren bett. hello there. last night was a cold one. we had a frost in places. but following on from that chilly start — at least, for a while — we did see some sunshine.

but the weather is changing quite quickly because the cloud is coming in, and this area of low pressure is to the west of us, out in the atlantic. but well ahead of it, this cloud is coming in from the west, and these weather fronts are bringing some rain and drizzle. so the weather is going downhill through the rest of the day. temperatures towards the end of the afternoon maybe making double figures. it�*s a bit cooler than it was yesterday across south—eastern areas, but there won�*t be much rain here. we do have rain across other areas pushing eastwards during this evening. the heaviest of the rain will be across scotland, before it clears away, and then we�*ll see some rain developing across more of england and wales by the early hours of the morning, into the end of the night. and there could be a fair bit of rain around as well, particularly over the hills. that�*ll keep the temperatures up. a bit chillier where we have some breaks in the cloud for scotland and northern ireland. and we should see more breaks in the cloud developing on sunday, once the morning rain clears away. sunny spells and just a few showers here and there. we do have this wet weather to move across england and wales. it does move eastwards fairly quickly out into the north sea, and then the cloud breaks up, sunny spells develop.

there will be a few showers around, mainly for the northern half of the uk. one or two heavy ones perhaps in northern england. but we�*re drawing in milder air, actually, tomorrow. temperatures across the board will be higher than today, reaching 15, or even 16, quite widely across england. and then, we�*ve got a couple of weakening weather fronts moving in overnight on sunday night. not much rain on those at all. we�*re left with this band of cloud and a few spots of rain first thing in the morning. that moves through and then there�*ll be some sunshine coming out, and many places will have a dry day. but the next weather system is arriving in the west, picking the winds up, particularly through the irish sea, and bringing some rain in here and across northern ireland. but we�*ve still got temperatures of reaching 15 or 16 degrees. and it�*s going to stay mild into tuesday as well. that area of low pressure is going to drive northwards, taking the wetter weather more across scotland overnight and then out of the way, so things will become drier and brighter through the day on tuesday, with some sunshine.

but we�*ve still got this cloud hanging back here in southern england, and it could turn wetter in the afternoon in the south—west. but it�*s still mild — temperatures, 15 or 16. live from london, this is bbc news. vaughan gething is elected as welsh labour leader and first minister of wales, making him the first black leader of any european country.
