Oleksii reznikov has been through more than 550 days of full scale war. I believe the Ministry Needs New approaches and other formats of interaction with both the military and society as a whole. Yuriy sak is a an adviser to ukraines Defence Minister he gave us his assessment of the change of the Defence Minister. We as a nation, we are now driven by one single objective and goal, which is to defeat the enemy on the battlefield and to win this war, and restore stability and security in europe and the world. The captain of our team is our commander in chief, president zelensky. So he makes decisions about how, in his view, is best to achieve the goals that we have ahead of us at this specific stage. So, the move that is announced now reflects the president s vision. You mentioned that reznikov was the Minister Of Defence was over 550 days. And as somebody who works with him closely, i can tell you that every single one of these 550 days, he woke up and went to bed with one single thought on his mind, how to get the Ukrainian Army more weapons, how to make sure the ukrainian defenders have the tools that they need to protect our shared values, to protect our cities, to protect our skies, to protect our people. We welcome now that the decision will be approved by parliament. I am sure the new Defence Minister mr umerov will continue on the path of the transformation of the Ukrainian Ministry of defence, the Ukrainian Armed forces. But mr Oleksii Reznikov as Minister Of Defence, his legacy is he has convinced ministers of defence around the world that the impossible is possible. It only takes a little bit longer. It all began with the United States telling Oleksii Reznikov in autumn 2021 that it is impossible for ukraine to even get stingers and javelins. And look, now we are getting f 16s. Now this is something that was not possible without his efforts, defication and personal sacrifice. Meanwhile ukraines generals are reporting significant progress in the Counter Offensive against russias invasion. They say their troops have breached the first line of russian defences in the south, near zaporizhzhia. The generals said extensive minefields had blocked troops for several weeks leaving them vulnerable to russian shelling. But they say that painstaking Mine Clearance has now allowed the forces to advance. Kyiv says its forces are making gains in the south of the country and has in recent weeks expanded its units towards the strategic town of tokmak a Logistical Centre for russian forces. Earlier i spoke to Peter Dickinson from the Eurasia Center at the atlantic council. I began by asking him about the changes being brought in by Presdient Zelensky at a time of scandal and corruption accusations in the Ukrainian Ministry of defence. It is probably the largest change in government since the full scale invasion began just over 18 months ago. The charges, or rather the allegations against the outgoing Minister Of Defence, Oleksii Reznikov, are, in fairness, not major in scale, if we take into consideration the volumes of military aid that ukraine is receiving. They generally relate to Domestic Procurement issues, they revolve around winter coats, eggs, food, things like this. But ukraine is really trying to demonstrate that it has a zero tolerance attitude to any form of corruption. And, of course, any suggestions of corruption within the security sector, within the military and Defence Sector of the country is particularly toxic at a time when it ukraine is trying to convince the world and International Partners that they can trust ukraine, ukraine is a reliable partner and the aid they provide will go to the places it needs to get to. And of course, we have a new Defence Minister coming in, mr rustem umerov, as mr zelensky is saying he wants a fresh start at the top of the mod. What do we know about him . His history, and what he sees for the future of ukraine . Well, mr umerov has a background not at ministerial level, but in government. He currently leads the state Property Fund and is overseeing the privatisation programmes. There is a strong Anti Corruption aspect in that role. He has previously been involved in negotiations for prisoner exchanges, and also on the grain deal that was brokered last summer with russia, the United Nations and turkey. So he has been involved at high levels of government for some time. His brief will very much be to continue cooperation with ukraines International Partners, while being seen to actively combat any form of corruption, or any grey areas within the ministry of defence, within the procurement systems, to make sure that they have the transparency they need. Its also worth noting that the candidate, mr umerov, is a member of ukraines muslim minority. So his appointment undermines the diversity of the ukrainian government. We now have a jewish president and a muslim Minister Of Defence in waiting. So this underlines the absurdity of russias attempts to try to portray ukraine as some kind of an ethnic fascist nazi state. And at the weekeend we have been hearing from ukrainian generals, saying they have broken through russian defences. Do you think the new head of the mod is going to have an impact on the front line . I dont think there will be any immediate impact. I think the troops at the moment have what they need, the generals have their plans in place, they will proceed. It may actually provide a morale boost for soldiers on the front lines, that are suffering significant losses and of course making enormous sacrifices. Reports of corruption within the ministry, within the Defence Sector, behind the front, back home, as it were, back home in kyiv and elsewhere, it is very damaging and very sapping for morale. So i would imagine that news of this change would be welcomed by the troops who will see it as a step in the right direction. But i dont anticipate any major changes immediately. Kenya is hosting the inaugural Africa Climate summit to discuss how the continent can take climate action. At least 23 African Heads Of State and government willjoin thousands of delegates to discuss a problem that is affecting the whole continent. Ethiopia, kenya and somalia recently endured its worst drought in decades with five consecutive failed rainy seasons. One of the deadliest storms to hit africa in the last two decades, cyclone freddy, ripped through malawi, mozambique and madagascar in late february killing over 1,000. West and Central Africa experienced one of the worst Flooding Disasters ever in 2022. More than 1,500 people were killed and 3. 2 million displaced. 0ur africa correspondent anne soy is following developments from nairobi and i asked her to talk me through what the organisers of the summit hoped to achieve. At the end of this three day summit, the kenyan president hopes that the delegates will have agreed on the solutions that they will be taking to the table during cop28, the un climate summit, upcoming in november in dubai. And so, as you say, he is trying to strike a positive tone to this and saying that they are not here to list grievances. They are not here to just talk about being a victim. This is a region that contributes least to climate change, but suffers the worst impact of it. And so they say everyone knows that. Now, can they discuss solutions . And he saying that africa has much of the unused arable land. If it was turned into agricultural productive land, this is a continent that could feed itself and feed the rest of the world. He is looking at the minerals that are on the continent, coltan and lithium that are used to manufacture batteries for electric vehicles. That can leapfrog that revolution towards green energy. This is a country that is already a leader in that. 93 of energy in kenya is from renewable sources. However, it has also faced controversies because it wanted to start exploiting coal, because its talking about wanting to get industrialised, and that is why we have activists here as well to just make sure that the political leaders who are showing some political will do not also backslide, so to speak. So, there is a lot of discussion that is going on here. The kenyan president wanted to be about solutions, rather than complaints. Lets talk about those solutions. The continent, we were just saying, has been hit by some of the worst Weather Systems across the globe. Its such a vulnerable part of the world. What can be done to help nations there . Well, the leaders here have been talking about using the resources that they already have. But they are also talking critically about financing, because that has been the biggest challenge. A lot of the finances that were promised during previous summits have not come through. And so they are discussing how else can Africa Finance the fight against this climate crisis. Theres a number of ideas on the table, including debt for nature swaps, which is controversial. We are looking forward to very vibrant discussions and see whether they will find consensus. Its not an easy thing for sa countries to agree on one way forward, but that is the hope at the end of the summit. A Weight Loss Injection will be prescribed to patients in the uk for the first time from today. Wegovy, also known as semaglutide, will be made available to patients through the nhs as part of a controlled and limited launch. 0ur Medical Editor fergus walsh reports. Could this weekly self administered medicine really tackle the uks expanding waistline . Research has shown wegovy can help clinically obese patients lose more than 10 of their body weight. The active ingredient called Semaglutide Suppresses appetite by mimicking a hormone released after eating, making you feel full. Supplies are likely to be limited at first. But nhs england says Tens Of Thousands of patients could eventually be offered wegovy for a maximum of two years. Although when people come off it, they usually put weight back on. Over 12 million adults in england are obese with a Body Mass Index of at least 30, and obesity is estimated to cost the nhs around £6. 5 billion a year. So the hope will be it could reduce pressure on hospitals. Last month, the makers of wegovy, danish firm novo nordisk, said its latest study showed the drug cut the risk of a stroke or heart attack in overweight people with Heart Disease by a fifth. Fergus walsh, bbc news. Around the world and across the uk. This is bbc news. Lets look at some other stories making news. A Bullying Complaint against former cabinet minister Gavin Williamson has been upheld by an expert panel in parliament. Mr williamson who quit the government after the allegations emerged has been told to apologise to the commons. The complaint was made by former government chief whip wendy morton and was related to the allocation of seating at the queens funeral. The parents of a teenager who died after failures in treating her sepsis are calling for patients to be given the right to an urgent Second Opinion if they feel their concerns are not being taken seriously. Martha mills, who would have been 16 today, died two years ago. An inquest said she could have survived had her care been better. Tescos Chief Executive says staff will be offered body cameras because of a rise in violent attacks. Physical assaults have increased by a third since last year and earlier this year British Retail Consortium found abuse against retail staff had almost doubled compared to pre covid levels. Similar action has already been taken by sainsbury� s, waitrose and co op. Youre live with bbc news. The opposition of the labour party has been making changes to his top team. Let us cross live to westminster and our political correspondent. An expected reshuffle, talk us through what is happening. Good morning. It is literally under way. A couple of updates, jim mcmahon who had been the shadow Environment Secretary is gone, he has been sacked from the shadow cabinet, he has officially stood down in a letter. It was widely expected he would be out of a job. In terms of appointments, that is starting now. The one that has been confirmed as Angela Rayner, the deputy leader of the labour party, has a new brief, she will be in charge of levelling up for the labour party. It is a domestic brief, something to get her teeth into. She has a new title, shadow deputy Prime Minister which seems to be keir starmer saying we are on the same page, she will be an important part of the top team. You might remember a couple of years ago when keir starmer tried to reshuffle Angela Rayner into a junior position, it backfired, caused problems for the office and in the end she got a promotion. Today she has a promotion again to do that Levelling Upjob With has a promotion again to do that Levelling Up Job with that deputy Prime Minister role. The question is over the course of the rest of the day how widespread is keir starmer going to be in changing his top team and what does he do with lisa nandy, and what does he do with lisa nandy, a popularfigure, who had been in that levelling upjob, no sign of what is happening to her. Let us read between the lines, what does this signify for labour going forward, and their approach . A really good question. We will have a better answer by the end of the day. What keir starmer is trying to do today is get his top Team Election ready, to say this is the people i will take to the electorate probably next year in a general election, the Labour Conference is in a few weeks which will give a chance to introduce people new to theirjobs. Fundamentally the their jobs. Fundamentally the question theirjobs. Fundamentally the question people are asking is, is keir starmer ready to take power . The polls suggest labour are miles ahead, the conservatives have problems, yes, they will try to claw back the ground, but keir starmer has to persuade the public and the electorate he is ready to take over as Prime Minister and what he is doing today is saying, i have had time to get to know my party and people and these are the calculations i am making about who should be in those top jobs. Calculations i am making about who should be in those topjobs. 0ne should be in those topjobs. One thing you always look for when people change jobs is does it suggest maybe there might be a change of direction in the labour party. Another question that might be answered over the course of the day. Let us look to number 10, a busy first day back, a big focus on this crumbling concrete affecting over 100 schools. This is a situation which will engulf the week for the government. A proper crisis for schools, loads closed already, the possibility more of this concrete could be found in more schools and that could lead to more schools and that could lead to more closures. The question the government is facing today is should it have known moore and dunmore earlier. The reason they are being asked that question is because there are concerns this concrete which have been raised for years and we heard this morning from a former senior official in the Department For Education the government was told three years ago it needed a lot more money to deal with school repairs. What happened . The budget was actually cut. Who was chancellor at the time, rishi sunak. He is inevitably facing questions today about whether part of this could have been avoided had that extra funding being increased rather than reduced. We heard from the Prime Minister within the last half hour, this is his response.

So questions about who gets otherjobs, throughout the day. Thank you. Let is head to the United States. 0rganisers of The Burning Man Festival in the Us State Of Nevada have postponed the events finale , the burning of a large wooden effigy, until monday. Its because of the treacherous weather conditions. Heavy rain has turned nevadas Black Rock Desert into a quagmire. Some of the Tens Of Thousands of people there have managed to leave, despite orders to stay put. 0ur North America correspondent david willis reports from the festival site. I want to know, Have You Ever Seen The Rain . Theyve seen it here. Whats thought to be the longest, heaviest rainfall since this festival was launched 37 years ago. The day before people were due to start heading home, the Dusty Desert Sand was transformed into a quagmire, prompting organisers to close the gates. A driving ban remains in force here but the organisers say its too wet and muddy for people to leave and theyre warning that heavy vehicles could end up getting bogged down in the mud. But for those who are desperate to get out of here, well, theyre not stopping them. And this morning saw a steady stream of vehicles headed for the exit. The advice to those stranded in the Ankle Deep Mud is conserve food, fuel and water supplies, because its unclear how long youll be here. For me and my husband, this is an escape from the hard things. And this is kind of hard. So im sad. When are we going to get out of here . Oh, thats a really good question. Everyone keeps saying your guess is as good as mine. What do you make of all this . I mean, im having a great time. Is it going to spoil the fun . No, clearly not. This week long festival transforms a remote area of northwestern nevada into a sprawling desert city. But even before the event got under way, organisers were dealing with flooding caused by the remnants of hurricane hilary. Burning man culminates with a large wooden effigy being set alight. That has been delayed, and its timing now depends entirely on the weather. David willis, bbc news, in black rock city, nevada. Before we go, let us head to ukraine and remind you of our top story. The Defence Minister there has been dismissed from his post. Volodymyr zelensky has announced that alexey reznikov, who led the military before the invasion, has stepped down. Stay with us here on bbc news. Hello again. For most of us today it will be dry, sunny and warm.

Beyond that into thursday, friday, and the weekend, remaining settled, and the weekend, remaining settled, a lot of dry and sunny weather, but breaking down at the weekend from the atlantic. This is your questions answered and today were talking about the crisis in schools due to crumbling concrete. The new term is getting under way in england, with more than 100 schools fully or partially closed, because of Safety Concerns about crumbling concrete. It is known as raac. In scotland, 35 schools are affected and surveys are under way in wales and Northern Ireland. Ministers have said the government will spend what it takes to make classrooms safe. We are going to give you a definition of raac in a second but let me introduce you to our panel. Joining me as nick eardley, Doctor John Roberts former president of the institute of Structural Engineers and fellow at the Royal Academy of engineers. Also cavallaro, from loughborough university. We need to be clear from the start on the type of concrete were talking about. Reinforced autoclaved aerated concrete is a lightweight material. Lets get more on this with our guest. Talk us through why this material would be used in schools if it has a life span that ends 30 or 40 years after it split up and what it looks like. ~ � ,. ,
