good afternoon and welcome to the bbc news at one. raf helicopters are trying to save the dam in derbyshire, amid fears it could burst and engulf much of the town of whaley bridge. the chinooks are dropping bags of sand, gravel and stone to shore up the dam wall. experts say the situation is critical. around 1,500 residents were moved out of their homes yesterday. the prime minister has said his thoughts are with them, and the government's emergency committee cobra will meet this afternoon. from whaley bridge, laura foster reports. the rain has gone but the hard work

goes on. chinook helicopters have been flying in every ten minutes since 5:30am, each armed with tonnes of sand and gravel. they have moved 200 tonnes so far, but engineers say they need to move at least double that to shore up the dam wall. all of the gravel coming local quarries. it's a difficult cry ask —— task. we have to get as low as we can. you can see behind us the guys and gals are taking a bit of time to get in there because we have to make sure it is done not too high to put more stress onto the dam, but we have to get them into centimetre square areas. it is like a lego block we areas. it is like a lego block we are building, put a foundation in there and carry on building on top of each other. the prop —— the problem is this spillway, damaged after a month's worth of rain fell in a week. it has put home injeopardy. worth of rain fell in a week. it has put home in jeopardy. the worth of rain fell in a week. it has put home injeopardy. the plan worth of rain fell in a week. it has put home in jeopardy. the plan for

the fire services to stop what is coming into the reservoir using the chinook and the raf coordinated to dam up those in lights, and of the same time to get as much water out of the reservoir as we can. there is still a risk it could collapse? yes, the structural engineer is very concerned about that. and basically, the information we have had is we have to do something here because it is not going to go away on its own. meetings like this have been happening throughout the night and all through this morning. it is a joined up operation. right now the operation —— the engineers are 21 more water pumped in. the idea is if you can reduce the amount of water in the reservoir, it reduces the pressure on the dam. after the dam spillway partially collapsed yesterday afternoon, people living in whaley bridge were told to evacuate is the time could be flooded. most stayed with friends and family. some were put up in hotels. others used camper vans. my houseis

hotels. others used camper vans. my house is about 30 feet from the river, so it is pretty risky, really. i don't know, if the dam went, i don't know if we would have a house, to be honest. the prime minister is called an emergency cobra meeting this afternoon to discuss the situation. engineers are still assessing what caused the damage to partially collapse but all the people who live here care about is that the warm, sunny weather continues and if, and when, they may be able to go back home. and we can speak to laura now. laura, what is the latest on those effo rts laura, what is the latest on those efforts to save the dam? well, they are working very hard in order to do exactly that. there is still an immediate danger to all the houses that lie in whaley bridge below this dam. but emergency services have teamed up, they are working around the clock. through the night and this morning. the truth is they are bringing in even more tonnes of ballast to give more support to this

dam wall. they are also bringing in even more water pumps to suck or pump the water out of the reservoir. the truth is the engineers are not going to be completely happy this situation is completely safe until the water level on one side is lower than damage to the wall on the other side. now the warm weather is on their side. that explains why the mood has changed a bit from the nerves that were around last night. but still, there is serious concern that this dam may in fact flood the town that it surrounds. laura, thank you. laura faster in whaley bridge. —— laura faster. 0ur science editor, david shukman, is here. david, tell us about the challenges the engineers are facing? you mentioned a race against time. you could also see this as a test of strength between the weight of the water in the reservoir and the strength or condition of the dam holding that water back. the big

unknown here is that when the water ove rflowed unknown here is that when the water overflowed down that slipway, and moved those enormous concrete panels, because the flow of water was so strong, exposing the mud of the embankment underneath, we still don't know what condition that left things in. how weak is the dam? what does that mean for the future? until people now, they have to deploy these emergency strategies, reducing these emergency strategies, reducing the water level, shoring up the dam itself, hoping it will be enough. some people are asking whether our infrastructure generally is fit for purpose in an era of climate change when we are seeing dramatic flooding? that is right. this was built in the 1830s, with mud and clay. a very similar kind of dam nearly broke in yorkshire, near rochester, did i mean rochester? sorry, i've forgotten the name! cracks appeared after a torrential downpour and people were evacuated.

the motorway was threatened. all of that meant there were questions raised. does this ageing victorian infrastructure, is it strong enough to cope with the kind of conditions we are seeing? climate scientists are very clear. they say it is absolutely certain that as air gets warmer, as it is, it can hold more moisture, which means you get heavier downpours. so the kind of conditions that we are seeing that lead to this threat right now in derbyshire, is the kind of thing we can expect to see more of. that means they will have to be a very careful look at whether all of the dams around the country built in victorian times are fit for purpose. david, thank you. david shukman. borisjohnson‘s effective parliamentary majority has been cut to just one, after the liberal democrats won the by—election in brecon and radnorshire. the party overturned a conservative majority of 8,000 to clinch the seat byjust over 11100 votes. labour were beaten into fourth place

by the brexit party. the new mpjane dodds said voters had chosen "hope over fear". tomos morgan reports. ina in a brexit voting area, a remain party coming out on top. in a brexit voting area, a remain party coming out on toplj in a brexit voting area, a remain party coming out on top. i do hereby declare that jane dodds is duly elected member of parliament for the said constituency. the clear message from the constituency‘s new mp to borisjohnson. from the constituency‘s new mp to boris johnson. my very first act as yourmp, when! boris johnson. my very first act as your mp, when i arrived in westminster, will be to find mr borisjohnson, wherever he is hiding, and tell him it loud and clear, stop playing with the future of our communities. it was celebrations all around in brecon this morning. the liberal democrats victory means the party

finally has a seat again in wales and it is a first boost for their new leader. this result sends the message that liberal democrats are winning again. and it comes off the back of her local election success, our best ever european election results, and it is clear that people don't have to settle for either borisjohnson orjeremy corbyn. the liberal democrats are providing a positive alternative and here in brecon and radnorshire people have voted for that in their droves. this by—election was triggered following conservative chris davies conviction in march of submitting false expenses. the result means the tories have a narrow majority of just one in westminster. it is never easy having a tiny working majority but the broader point is it will not distract us from what we have explicitly promised to do. that is deliver brexit so we can seize the opportunities it provides. this constituency lies within the county

of rural powys, where the brexit party came out on top in the european parliamentary elections. it comes as no surprise that the brexit party came third. and brexit was no doubt a hugely contributing factor amongst constituents. we voted to come out and that is the reason we are here. it is driving us up the wall. i have heard too much about brexit, yes. i voted liberal alliance. the narrow victory for the lib dems was helped by the other remain parties, clyde comrie and the greens, choosing not to stand, handing the victory to jane dodds with just over a thousand votes. labour suffered a significant blow, falling to fourth, prompting further questions about its stance on brexit. ambiguity has not helped us in the last few years. we have tried to say to brexit voters, we are in favour of brexit, but we are in favour of

remain. without a doubt this is a blow for the new prime minister. he was in wales only on tuesday and came to the constituency to try and gather support for his man, but that just wasn't enough. his first electoral task failed. boris johnson's task of getting any future brexit vote through parliament has become trigger. —— trickier. 0ur political correspondent, peter saull, is in westminster. is this a by—election result with a wider, potentially wider, political significance? yeah, the lib dem leaderjo swinson said this proved borisjohnson has leaderjo swinson said this proved boris johnson has no leaderjo swinson said this proved borisjohnson has no mandate to deliver. he will not change in strategy. he will go ahead with this do ordie strategy. he will go ahead with this do or die idea of us leaving the european union on october 31. that is clearly a blow to the new prime minister. having said that, many people were predicting that the

conservatives would lose more votes in this by—election to the brexit party. there is a little bit of evidence of a boris bounce. but if he is going to win a majority at a general election, he needs a johnson jump general election, he needs a johnson jump ready to regain seats like this and take seats in other parts of the country. you can understand why he might be tempted to go into a general election at some point soon, where the brexit party show no sign of going away. it would be a risk if he went into an election having not delivered a brexit. the temptation is there because of the parliamentary numbers here. the government's working majority down to one. we saw how difficult it was, time and time again, for theresa may to pass legislation. when mps return here after their summer break, there could be some pretty massive parliamentary battles ahead. not least the prospect of a confidence vote in the new government. peter, thank you.

july may have been the hottest month the world has ever had. provisional figures suggest global temperatures last month were 1.2 degrees above pre—industrial levels. the uk recently experienced its highest ever recorded temperature — 38.7 degrees in cambridge — and this summer has seen weeks of sweltering weather across europe. here's our science correspondent, pallab ghosh. it's not water they're walking through, but a heat haze on the streets in japan. and it has been the same story across many parts of the world. record temperatures in finland. a three—week heatwave in china, too. and now it's official. july is one of the hottest, if not the hottest, on record. and july isn't alone. 2019 has been very warm globally. each month so far is among the four warmest for the month in question. and june has been the highest ever. this particular month has been very warm, but to me

this is not really the main point. the main point is that not only this month has been very warm, but last month was very warm. all months during 2019 were very warm in terms of comparing with other years. and that trend is not likely to stop unless we do something about curbing greenhouse gas emissions. the results are based on billions of measurements from satellites, ships, aircraft and weather stations all across the world. these latest figures are part of long term trend in rising global temperatures. computer models of the impact of climate change predict that more summer temperature records are likely to be broken all across the world more often. and a separate assessment by the world weather attribution group shows the fingerprint of climate change on the current heatwave in western europe. temperatures are up to three degrees hotter than they otherwise would have been, because of greenhouse gases created by human activities.

this record shows that the average temperature around the world in july was about 1.2 degrees above its preindustrial rate. now that's getting very close to the 1.5 degree threshold the country signed up to in the paris agreement, and will put pressure on governments that they really now have to act urgently and set a plan to cut their emissions down to zero by the middle of this century. individual heatwaves can't be pinned to human created global warming. but the increase in extremes of weather that we are beginning to see, is in line with the predictions made by climate change experts, and they say they are likely to get worse and more frequent. pallab ghosh, bbc news. so how much warmer is your city? to find out how where you live might be affected

by climate change, and what can be done about it, go to bbc.co.uk/news. more than 50,000 people are facing disruption to their travel plans, after the collapse of two package holiday firms. super break and super breakm are both in administration. our personal finance correspondent simon gompertz reports. yes, it is the holidays and a terrible time for a holiday provider to go under. super break has 400 people —— has 400 people overseas and many bookings, many in the uk. and many customers have but hotels via laterooms. because the payment go straight to the hotel, they should be ok. the stories have been emerging on social media are people who think their breaks might be ruined, including winter bookings in iceland, for instance. we have

researched the company thoroughly before we paid out the money and there was no hint at that time, just a month ago, that there was any financial difficulties at all. super break was drumming up business close to its end, never too late to visit manchester, it said. and in a statement after its failure, it added that hotel only bookings can be cancelled and people might be asked to pay twice. this is a massive worry for thousands of people who might have booked tickets to shows in london's west end or entries to a theme park, along with the hotel rooms to put the family up for tonight. and the concerns are, well, there hassle factor, trying to sort it all out, whether they will be allowed in and whether they will lose their money. there is some reassurance, their deep, the aquarium in hull, would honour any bookings. legoland said they were

charge 50% of the gate price. travel body abta says people should be able to get their money back later.l rail ticket plus a theatre ticket is a holiday which will be protected by abta. if you have a package holiday plus a light, that will be protected by atol. if you have accommodation only, hotel booking on its own, that will not typically be protected. abta advises those on a break paying for the hotel should get receipts and if it is a package, they will be reimbursed after making a claim. the governor of the bank of england, mark carney, has warned that many businesses could quickly find they are not viable, if the uk leaves the eu without a deal at the end of october. he also told the bbc that food and fuel prices could rise, and incomes could also be hit. it is not your usual hallowe'en

nightmare but the fear is that on 0ctober nightmare but the fear is that on october the 31st, a no—deal brexit could me a slowdown in inputs entering the country and this time, it could also hit firms hard, making many of them unprofitable. mark carney says he is not playing at the scare. with no-deal, the shock to the economy is instantaneous and insta ntly, the economy is instantaneous and instantly, you have these supply, not just instantly, you have these supply, notjust disruptions, so i am not talking about just the notjust disruptions, so i am not talking aboutjust the issues at the ports, which are real, but you actually have businesses that no longer are economic. the well-known risk is that a shift to the world trade organisation regime means higher tariffs added to imported or exported goods. but what mark carney is saying is that it could also be inflationary in other ways. mark carney has highlighted two things that could happen in a no—deal brexit, one is that the pound gets wea ker brexit, one is that the pound gets weaker so your pound buys you fewer dollars or euros to buy imported goods with so those prices go up.

the other thing that could happen is the supply of goods from abroad going through our ports and airports slows down and that could also push up slows down and that could also push up prices. it may take a while to get to boris johnson's up prices. it may take a while to get to borisjohnson's vision of sunlit uplands after a no—deal brexit, mr carney said, because the wea ker brexit, mr carney said, because the weaker pound expected on the market may hit the purses and wallets of consumers at petrol station forecourt and grocery stores, but his data shows most businesses are as prepared as they can be and mr carney‘s view is not the only one. there are many different types of a no—deal and mark carney seems to be talking about the worst possible type, which i don't think will happen because at least some businesses have done some preparations. and it would be really useful if rather than throw a few scary sound bites every now and then, mark carney and his team at then, mark carney and his team at the bank provide a full set of four because of what they actually think would happen. there is no sign yet of the bank of england is ready to do that. no need to really scare people, it is not hallowe'en yet!

our top story this lunchtime: raf helicopter crews in a race against time to save a dam before it bursts and floods the town of whaley bridge. and coming up at the ashes, england's batsmen tried to thrive, or at least survive, on the second day at edgbaston. coming up on bbc news: defending champion georgia hall is challenging for the lead at woburn, amid an english charge on day two of the women's british open. the united states has formally withdrawn from a nuclear weapons treaty with russia, raising fears of a new arms race. the agreement — signed in 1987 by ronald reagan and mikhail gorbachev — banned intermediate—range nuclear missiles.

well, the trump administration has blamed russia for breaching the terms of the treaty, an accusation that moscow denies. 0ur diplomatic correspondent, james landale, reports. it was a crucial moment towards the ending of the cold war — the moment, in 1987, when the leaders of the united states and soviet union signed the intermediate—range nuclear forces treaty. ronald reagan and mikhail gorbachev promised to destroy all their missiles with ranges between 300 miles and 3,400 miles, eliminating at a stroke an entire class of nuclear weapons. the mobile ground launched nuclear weapons were hard to detect and could strike anywhere in europe within minutes, but in recent years, russia has begun testing and deploying a new cruise missile, which the us says breaches the inf treaty. so they've withdrawn from the agreement, much to the concern of the international community.

the world will lose an invaluable brake on nuclear war and this will likely not reduce the threat posed by ballistic missiles. regardless of what transpires, the parties should avoid destabilising developments and urgently seek agreement on a new common path for international arms control. the us had given russia six months to comply with the treaty, but moscow denied its new missile broke the rules and blames the us for ending the agreement. the risk now is that the demise of the treaty sparks a new arms race between russia, china and the us. nato leaders promised to ensure that the alliance's defences remained credible, but said they would not mirror russia and deploy new land—based missiles. we don't want a new arms race. that's the reason why we will respond in a measured and defensive way. and that's also the reason why we

continue to work for arms control, nonproliferation and disarmament. three decades ago, the leaders of the world's super powers acted to reduce the nuclear threat in europe. their treaty is now dead, and yet another part of the international rules—based order has been consigned to history. james landale, bbc news. england's cricketers are making steady progress replying to australia's total of 284, on the second day of the first ashes test. 0ur sports correspondent joe wilson is at edgbaston. yes, and we have to remember that a test match lasts five days, no need to rush. the england team is a mixture of newcomers and experienced a test match players and today, we have seen a morning web play moves intriguingly, not necessarily rapidly. james anderson came to edgbaston today with so much uncertain. no crutches, just morning coffee,

but carrying an injured calf. when will he be fit to play again? for england's opening batsmen, it was clear, make runs today. jason roy and rory burns had a friendly security guard for company at 9am. by 11, they were surrounded by australians. jason roy found a gap between them. fortune favours the brave sometimes. there was nothing lucky about this. a full—blooded four from rory burns. now, that's the way to build your confidence! but the next edge from roy's bat found the fielder. steve smith, in fact. pattinson the bowler, and jason roy's first ashes innings was over. he'd scored ten. rory burns has his own way of watching the ball. sometimes, you've got to avoid it, quick. australia's fast bowlers were coming in hard, searching for any sign of weakness. spin bowling presents different challenges. slowly, england were scoring the runs to get nearer to australia's first—innings total. 284 was on the horizon. dista ntly. now look closely at

something extraordinary. mysterious. joe root was given out here because the umpire thought the ball had brushed his bat. root disagreed. the sound wave displayed the ball had in fact hit the stumps. those green bails have to come off for the batsman to be out. they do move. but from this delivery, they wobbled and fell back in place. that was rather fortunate, australia may have suggested — to england's captain. and to remind you that in a few moments, england will resume in their first moments, england will resume in theirfirst innings 71—1 in bright sunshine, joe root 11 not out and rory burns on 41 and showing an appropriate degree of ashes patients. thank you very much. there's plenty of british interest at the top of the leaderboard

at the british open golf at woburn. defending champion georgia hall and fellow brit bronte law have both produced strong performances. our sports correspondent jo currie reports. in golf, nothing stays still for long. sometimes, it is hard to keep up, buta long. sometimes, it is hard to keep up, but a good place to start is with the reigning champion. georgia hall started the defence of her title with a solid opening round. but this morning, she found top gear and almost got a flemish free round with four birdies to put her at six under. she was not the only englishwoman going well, bronte law finished with a round of 67, leaving her on seven under par. that is the kind of form that wins you majors. and a place in the solheim cup team. luckily for bronte law, she is playing alongside europe's captain catriona matthew, never a better time to impress! well, charley hull was the best of the british yesterday finishing two off the lead and she knows this course better than anyone having been a member

here since she was nine. but if she is to win her first major title, she is to win her first major title, she is going to need another strong start today. but with a home crowd comes home expectations. the pressure she will have to deal with today. one player also making herself look at home is america's lysette salas who took her chances to rise to the top of the leaderboard. with to rise to the top of the leaderboa rd. with overnight to rise to the top of the leaderboard. with overnight leader ashleigh buhai two out in the next hour. bbc news, woburn. police in the us state of washington are used to stopping motorists who drive too fast, but they got the shock of their lives when they saw a plane racing down the road. and when the light aircraft finally came to a halt, of course, the officers had to knock on the window and have a word with the pilot. richard lister reports. is it a bird? no, it's a plane — caught on a police dash cam, buzzing low over the morning commute. i thought, from a far distance,

it was a remote—controlled plane. as it continued going north, it got bigger and bigger and bigger. to the point of, 0k, that's really close to the ground, i think he's trying to land it on state route 7. trooper thompson immediately turned around, braced for what could have been a disaster. i see isee him i see him getting closer to the ground, the wheels get close to the ground. he was able to put on the brakes. it wasn't a conventional landing, but no—one was hurt. the pilot even managed to stop at the red light. it may be the most bizarre traffic stop of trooper thompson's career. the pilot, david acklam, had been flying to work when he reported a fuel problem with his kr2 aircraft. amazingly, the incident barely interrupted the flow of traffic. he didn't even get a ticket. tomorrow, though, he'll be driving! richard lister, bbc news. time for a look at the weather. here's darren bett. a few flood warnings in north west

england and
