so far, a full list of the schools affected has not been made public. worth taking a moment to find out a bit more about the concrete at the centre of all this. raac, to give its full name, is reinforced autoclaved aerated concrete. it's a lightweight concrete that was used in roofs, floors, and walls between the 19505 and 1990s. it's a cheaper alternative to standard concrete because it's aerated, or "bubbly". however, it's less durable with a limited life span of around 30 years, and its structural behaviour differs "significa ntly" from traditional reinforced concrete. the health and safety authority says raac is now beyond its life span and may "collapse with little or no notice". let's get more now from our correspondent helena wilkinson, who's at a school in south london. just take us through what had teachers or having to suddenly deal with now. it teachers or having to suddenly deal with now. . , ., ., , with now. it was around this time yesterday. _ with now. it was around this time yesterday, wasn't _ with now. it was around this time yesterday, wasn't to, _ with now. it was around this time yesterday, wasn't to, matthew, l with now. it was around this time - yesterday, wasn't to, matthew, when the government announced this policy change that schools that did have raac, this particular type of concrete in their buildings, that they would have to not allow anybody inside that area of the building. so with days to go until the start of the academic year and start of the term, which for many schools in england is next week, head teachers and teachers are scrambling to put plans into place. as you say, the government still hasn't published a list of which schools are affected. we know that there are more than 100 schools affected by this, but they haven't published that list and the reason the government gave earlier is because they say they want parents to find out from head teachers, and at some stage after that they should publish a list. but where we are is in a school in brixton, in south london, a primary school, and a couple weeks ago parents here were told that in the junior section of the site behind us at the school, raac has been discovered, and therefore they'll have to relocate around 200 pupils from the junior site to a completely different school, about a mile and a half away from we are, and they'll have to carry out their lessons at the start of the term at this different school. for how long, they don't know that yet, but dell obviously be bringing in surveyors at the school to try to rectify the problem with this concrete —— they'll obviously be bringing. it's a similar situation for all those schools affected right across england, and for many parents over the last 2a hours, there's been clear concern because that list of schools has not yet been published by the government, many have been left wondering, is it my child's school that'll be affected? most of them should've found out by now from head teachers. them should've found out by now from head teachers-— head teachers. here we are talking on frida , head teachers. here we are talking on friday. most— head teachers. here we are talking on friday, most of— head teachers. here we are talking on friday, most of those _ head teachers. here we are talking on friday, most of those schools . on friday, most of those schools will reopen on monday. there is still so much we don't know about the story — you're talking about the exact schools on that list, that's one thing we don't know, we don't know how many pupils in the end may have to be taught remotely, and we don't know how long it'll take to actually take this type of concrete out of those buildings and get back to any sort of normality, do we? know, a lot of questions still remain, and you rightly point out that many of the big questions heads are asking and parents are asking. we spoke to a nine—year—old girl who will be at the junior school next week, but she will be one of the pupils who will have to move to a different school. just talking to her, she was actually feeling quite anxious when she found out that her school was one of the ones that'll be affected by this, and she will have to go to a different school next week. she was anxious because she thought they might have to do online learning. so it's notjust head teachers and teachers grappling with this and put plans into place, it's also some pupils as well. but again, it depends on the school, where the concrete is in the school — for some schools it mightjust be an part of the building, a small area, in which case they might not have to shut the school or partially close it. but there'll be other schools, we think around 2a, that may have to fully close from that list of more than 100. as i say, the government has not yet published that full list school lists —— schools yet. but on the bbc news website, we are collecting all the schools we know so far. the reason we know the school is affected is because they put a statement on their website on 18 august, so a couple weeks ago, telling parents that some children, about 200, will have to relocate elsewhere. a lot of planning over this weekend and over the coming days to try to get things into place. so the focus can be on safety as a priority for children, paul also to make sure that they continue with their education —— but also. continue with their education -- but also. ., , continue with their education -- but also. . , . ., ., also. thanks very much, helena, for all that. with more on this, here's our head of statistics robert cuffe. there are a lot of claims and counterclaims about the money being spent to actually fix all this, take me through all that.— me through all that. schools minister nick _ me through all that. schools minister nick gibb _ me through all that. schools minister nick gibb told - me through all that. schools minister nick gibb told ssc| me through all that. schools - minister nick gibb told bbc earlier today that we spend more than £15 billion just today that we spend more than £15 billionjust on repair today that we spend more than £15 billion just on repair and maintenance of school buildings since 2015 — but the union leader around the same time was telling us there were his underinvestment of more than twice that, around £35 billion. they're both asking slightly different questions and their numbers stack up, so it's true to say we've found the macro spent £15 billion, it's an underestimate of how much they've spent, because it doesn't include rebuilding parts of schools. that's probably about the best part of £3 billion a year, so if anything the minister was slightly under reporting. the general secretary of the national education union says they were spending about £2.5 billion less every year than we were around the end of the labour government in 2010, that's when you adjust for rising prices. now that's also true but it's the whole education budget, it's notjust schools, but universities, notjust buildings but it systems, it's a whole capital investment. so that's technically correct but it's not the best number to use to discuss this issue. hind to use to discuss this issue. and when you _ to use to discuss this issue. and when you look— to use to discuss this issue. and when you look at _ to use to discuss this issue. and when you look at the figures, where does that take you in terms of whether it'll be enough to fix this? knowing we are spending less than we did in 2010 doesn't tell you if it's enough, but i think we have a pretty clear answer that question, which is we are not. £4 billion of gear was in the spending review in 2020, and that's lower than what they needed to bring schools up to scratch —— £4 billion a year. but the treasury, as always happens in these spending reviews, didn't report all the money, £3 billion last year. so there's certainly a shortfall there, it's just not quite at the same level as was implied by the national education union.— education union. briefly and finall , education union. briefly and finally. a — education union. briefly and finally, a lot _ education

my colleague has been ringing around different departments to find out what we know. and as of right now, i can tell you that we know about 2k hospitals where we know there's raac, several of those will need to be rebuilt, for buildings owned by the department of wrecking pensions, there's six courts and tribunal buildings, but that's of today. they convened across government groups to start looking at this injuly, and they said that surveys are ongoing so we will find out more and more about this over the coming weeks and months, and that'll be a nasty surprise for the people looking for a cabinet investment.— a cabinet investment. thanks for takin: us a cabinet investment. thanks for taking us through _ a cabinet investment. thanks for taking us through all _ a cabinet investment.

important story later in the programme. hong kong and parts of mainland china are being battered by a super typhoon. authorities in hong kong, have raised the emergency alert level to its maximum. winds as high as 200kph and heavy rains have already hit the area. theses are the latest pictures from hong kong. these are the very latest pictures from our colleagues at bbc chinese. this is hong kong. you can see the powerful winds have knocked over trees outside this residential building. people have been warned to stay indoors. and you can see why — this reporter in guangdong province, from the china meteorological administration, was trying his best to update viewers on the typhoon. and here it is — seen from space — on the left of the screen, with another smaller typhoon to the right. we've been talking to some residents in discovery bay, in hong kong. they told us more about here experience there. the government told us already yesterday that it will be a day off, all the schools, stock exchange, businesses are closed. it's the closest typhoon we have had in the past 20 years, it's meant to be passing us by at midnight at about a0 kilometres from here. i don't know whether you can see it, we have got buckets full of water passing by. we have got literally leaking windows from the terrace, broken trees, etc. chairs flying. chairs flying, a chair literally just flew away two minutes before we came online. so it's been pretty bad. the pictures were from actually the main entrance to our block. we have actually had, just a couple of hours ago, a couple of trees falling down, cutting off the access to our residential area. but we've had a very good response from the emergency and fire department. they came literally within15—20 minutes. they cut through the emergency access for any ambulances orjust in case, touch wood, nothing happens. but we're still three hours away from midnight where the typhoon is meant to be passing us by. i don't think it will be a night where we speak through. it's a sleepless night ahead of us. i've been talking to a photographer and writer martin williams on an island ten kilometres from hong kong, who began by explaining how the storm is affecting where he lives. went outside, and i was hoping to take my computer outside, but the camera doesn't let me show it. there are trees just behind me that have been lashed by the wind. every so often, there are powerful hurricane and plus force gusts that are just whipping through, blasting the trees. so this kind of perpetual noise outside and every so often there's a rush. it's almost like an express train is going past the house. but we're quite sheltered at the moment, so i'm a bit more concerned about what will happen when the wind goes around to the south. i'm going to put on to the screen some pictures that you sent us from a little earlier in the day, because they're wonderful pictures, but it doesn't show really the intensity quite of the super typhoon hitting. how quickly did all of this that is currently on our screen actually change? well, i took a couple of shots last night in in the evening. so it's quite dramatic clouds that looked almost like they spawned a tornado. and then it's been fairly calm since it's been a long time. this is the longest — this is an exceptional storm. it's the longest that we've waited from the gale signal to get gales. that happened this afternoon. and during this afternoon, the gales arrived. by the end of the afternoon, there were gale force winds blowing. then we got the warning. there were hurricane force winds coming. very soon after that, within 2—3 hours, we got the hurricane t—10 signal, it's called in hong kong that says there are hurricane force winds blowing. and i've been looking at some of the figures, as well, showing 160 kilometre — that's average, the ten minute average wind speed in eastern hong kong. so they're starting to move across the south of the territory now. it's difficult to actually understand what wind speeds of that dimension is actually like in practice. but you described even the sound of it from inside of your house now, in terms of the warnings, the preparedness. take me through that. this time, it's been kind of exceptional. we've been hearing quite a bit about it. it's been a weird storm, this one, because it made us sort of loop around near the philippines. no—one knew quite where it would go, in taiwan. then when it started getting close, then we started getting better and better warnings because if we get very hard, if the storm lands and we've also had this in the warnings, if it lands just to the east of us, then it would dissipate and then go over hong kong as just some wind and some rain. a bit dramatic, but not the storm surge that we're starting to hear about now, which is the rising sea level. and that now with the storm place south of hong kong, that's, if you like, the perfect storm for the hong kong situation. it's really close just to the south. the main winds are starting to blow. they're blowing north now. they'll swing around to the east. they'll swing around to the south later and start blowing, blowing the waves and looking — ijust heard you mention about a place in the new territories, and i can see there that it's going almost vertical. i'm glancing at my computer screen there, and as the tide gauges, as the tide really comes in. and many years ago, there was a typhoon that killed about 10,000 people in hong kong, i think a 1937 one. and that was a lot of it because of storm surge. so we make a big fuss about the wind, and there 200kph winds blowing 200kph, 100 plus miles an hour. and that's consistent wind. notjust a gust like you hear of in the uk, but when the typhoon has got the surge coming in and this is almost like a little tsunami, but with powerful wind driven waves, that is that can be the killer. and a lot of people really don't know much about this in hong kong. now, i've read about typhoons since i arrived here a lot of years ago, and this is by far the biggest, the strongest typhoon that i've been in. life to the white house, joe biden... let's but the microphones ups popular at the same time, inflation continues to fall. it’s inflation continues to fall. it's now around — inflation continues to fall. it's now around 396, _ inflation continues to fall. it�*s now around 3%, and one third of what it was one year ago. in fact we learned yesterday that over the past three months, inflation will close to what it was close to what it was before the pandemic. pay for low—wage workers has grown at the fastest pace for low—wage workers in two decades. remember, some experts said to get inflation under control, we needed higher unemployment and lower wages. we needed higher unemployment and lowerwages. i've we needed higher unemployment and lower wages. i've never thought that was the problem, too many people having a job, or that working people were making too much money. now, after months and months of bringing inflation down while at the same time adding jobs and growing wages, it matters. and it's no accident. i came to office determined to rebuild the economy in a different way, from the economy in a different way, from the bottom up, not the top down will stop to move away from trickle—down economics and instead focus on the middle class. because

significant here in a moment or two. around the world and across the uk, this is bbc news. let's look at some other stories making news. one of the uk's biggest mortgage lenders say house prices have seen their biggest annual fall since 2009. the figures from nationwide show prices dropped by 5.3% lower than the year before. it said higher borrowing costs for buyers had led to a slowdown in

her mother have been jailed for life for murdering two men, who were killed in a high—speed car chase. mahek bukhari, who's 2a, was ordered to serve at least 31 years and eight months. her mother, ansreen bukhari, was given a minimum term of 26 years and nine months. saqib hussain and hashim ijazuddin, who were both 21, died when their car was rammed off the a116 dual carriageway last year. they were initially chased by a masked gang, recruited by the mother and daughter. now to washington, in the courts, where we're about to get sentencing of two members of the proud boys — the group that were central ring leaders in the storming of the capitol on january the 6th, 2021 — and the attempt to overturn the results of the presidential election. some of the group's leading figures have received long jail sentences in the last 2a hours. yesterday, the former proud boys leaderjoseph biggs was given 17 years. another, zachary rehl, got 15 years for his involvement. in the next few minutes, we're expecting dominic pezolla — who broke into the capitol building through a window, carrying a riot shield — he'll be sentenced, followed soon after by ethan nordean. nordean, like biggs and rehl, found guilty of "seditious conspiracy", as well as a host of other charges. earlier, i spoke to our washington correspondent wyre davies on what we can expect from the sentencing of these two today. a batch of cases, five in total, which deals, of course, with the aftermath of the 2020 election. the proud boys describe themselves as a "pro—western boys' drinking club", but of course, they were basically donald trump's foot soldiers. they were among the first to be involved in that march on congress onjanuary the 6th, just after the those presidential elections where they and others, which they and others, of course, believed had been stolen. now, they, in their defence, say they were acting on donald trump's implicit instructions in a tv debate in the run—up to the election. mr trump had famously told the proud boys to "stand back and stand by". and on the day, including the morning ofjanuary the 6th, as well, mr trump was seen to use what prosecutors have described as inflammatory language, encouraging people like the proud boys, 0ath keepers and other groups who thought the election had been stolen to march on the capitol. now, we all saw the riotous events on the capitol itself. and over the last few days and indeed into next week, members of the proud boys, leaders of the proud boys movement, have been sentenced or will be sentenced to long term imprisonment. joe biggs, as you say, who was a leader from florida, he was sentenced to 17 years in prison, zachary rehl was sentenced to 15 years. and today, we've got two more members of the proud boys organisation who are facing long sentences — and critically next week, enrique tarrio, who was the proud boys leader. he will also be sentenced and perhaps can expect the longest sentence of all. in terms of those two sentences we're expecting in the next little while, i mean, pezolla, he was the only one of that group who was found not guilty of that charge of seditious conspiracy. but the prosecution is still looking for a sentence of around 20 years, aren't they? yeah, the prosecutors have actually looked for longer sentences given by what was handed down yesterday, 17 years and 15 years. perhaps the two today can receive similar length sentences. prosecutors have said biggs viewed himself and this movement as a second american revolution, where he and the other patriots would retake the government by force. and prosecutors say the harsh sentences are indeed long, but they say they're also an important example, mindful of the fact that, of course, america is facing another presidential election in just over a year's time. we are still waiting for that sentencing. south africa's president, cyril ramaposa, has called for urgent action, to tackle the problems of housing in inner—city areas after 7a people died in a fire injohannesburg. many of the residents were migrants, who were renting rooms from criminal gangs who had taken over the former industrial building. the process of identifying bodies is continuing. 0ur correspondent shingai nyoka sent us this update from johannesburg. a day after the fire broke out, emergency services are still at the scene conducting one final sweep in search of remains. and the families are also still here in search of answers. and some of that trauma is visible on their faces. some of them bear the physical scars of the events of yesterday broken bones, head injuries. over 70 people are now confirmed to have died, and the grim task of identifying them is underway. but many of the relatives here say that their relatives are still missing and they don't know whether they made it out alive. the south african government has pledged to assist the survivors, but it's a very difficult situation for many of them because they are undocumented migrants and so it's unclear whether they will come forward to get that assistance. and so in the second day after the fire, a lot of people here are unsure about what happens next. stay with us here on bbc news. hello. the weather is changing over the next few days. a change to something drier and warmer with some spells of sunshine. in fact, a decent weekend in prospect if you have outdoor plans. today, we have seen some areas of cloud, and indeed some quite sharp showers. this is the satellite picture from earlier on — a strip of cloud across northern ireland, southern scotland, northern england and some shower clouds further south as showers continuing to ease. through the evening, te will continue to see some bits and pieces of clouds and mist and fog patches likely to develop, as well, but also some clear spells. and where we have those clear skies across some parts of highlands, scotland, temperatures could drop down to around 1—2 celsius. it will be milder than that. further south, saturday's weather story is one of high pressure which will be building its way across the uk, chasing this frontal system away eastwards. so some areas of low cloud, a bit of mist and fog around. the chance of 1—2 showers popping up through the day, but they should generally be quite light in nature. most places will stay dry. just a bit more cloud and more of a breeze through the afternoon into the far northwest of scotland. but temperatures up to 21 celsius in aberdeen and in belfast, 2a in london — could just get a little warmer than that across some parts of southeast england. and then into the evening, most places fine and dry with some late sunshine, but more cloud and some rain into the far north of scotland, courtesy of this frontal system which willjust continue to slide its way through during sunday. 0ur area of high pressure centred across the south of the uk. under the centre of the high with light winds, again, some mist and fog patches to start sunday which would tend to lift and clear to reveal some sunny spells. closest to our weather front in the north of scotland, we willjust see more cloud and a bit of rain. but eastern scotland with some shelter from the breeze, 20—23 celsius. come further south, highs of 25, 26, maybe 27 celsius into next week. high pressure tends to retreat eastwards, low pressure trying to squeeze in from the atlantic. and this arrangement of weather systems will bring us a broadly southerly air flow. and that will introduce some warmer air from the near continent. now, there's some uncertainty about just how warm it will get, but we could well be looking at values into the mid—to—high—20s, possibly close to 30 celsius for some of us. it does look like turning a bit more unsettled by the end of next week. a this is bbc news, the headlines there are fears that the number of english schools forced to close buildings because of crumbling concrete — could rise. a tik tok
