more than 50,000 rail workers are walking out today, causing the biggest strike disruption on the railways this year. 0nly around 11% of the usual saturday timetable will be able to run. in some parts of the country, there are no trains at all. members of four unions are taking part in the strike in a long—running dispute over pay, jobs and conditions. 0ur transport correspondent, katy austin reports. another train strike, and it's the biggest yet. karen from staffordshire is running the london marathon tomorrow to fundraise for the hospital where she had breast cancer treatment. news of the strike meant she had to make other plans to get there. so, for me, thisjust blew everything apart. i couldn't even begin to think of how we would get there. so ijust worried. and until we knew what our plan was, ijust panicked, just just worried about it. the red lines on this map are the only parts of the rail network which do have services today. where trains are running, they started a lot later than usual and they'll finish a lot earlier than normal as well.

there are no trains running between london and some other major cities, including edinburgh, newcastle and brighton. why is this all happening? well, the train drivers union aslef is demanding a pay rise amid high inflation, the rmt wants that for its rail worker members too, and it argues job security and working conditions are under threat. both unions insist they didn't target the london marathon. whenever we put strikes on, it's going to inconvenience people. we don't want to do that. we'd much rather have a settlement. we'd much rather get out of this dispute so that our members can provide the service. we have to keep the dispute going. we've been going nearly six months now, and we have to keep the momentum going. we've got full support from the public. we believe. there's many people that, even the people that are inconvenienced, that are supporting us every day, we're on these picket lines. the industry argues the pandemic has left a financial hole and changed the way people travel. we want to give our staff a pay increase, but it

has to be self—funding from within the industry, because we can't afford to keep taking more taxpayers' money. so meaningful reform means that we can generate money, that we can then say to government, "we believe that this is a sensible deal, that we can give our staff a pay increase." rail bosses and unions say they'll keep talking, but more strikes could be coming down the line. that was katie austin reporting. 0ur correspondent sanchia berg joins me now from london euston. the station is closed, people are being turned away. there will be no trains in or out until seven or eight o'clock tomorrow morning. while this has been really well publicised so that participants in the london marathon for example, as you heard in katie's piece can make alternative arrangements, and people will be making alternative arrangements to travel up to the conservative party conference not everyone has got the message. earlier we spoke to several people

describe the strikes as a war of attrition that benefits no one. and they are hoping that actually many workers may be attracted to the offers they have already made, which are 8% over two years, conditional on changes being met. and who also say that a lot of workers are losing a lot of money. they feel it in their pocket, these continuous strike days. thank you very much, sancho berg ativan them's euston station. the cost of gas and electricity for uk households has a two—year cap will prevent prices going up further.

0ne one of liz truss's first acts was to support package. what can we do to save our energy usage? there are lots of tips from things like reducing and changing the way that you cook, using your oven and hob is more expensive than using a microwave or a slow cooker. things like drying your clothes, don't use the tumble dryer, air dry your clothes. during this last week by the bbc has been out and about speaking to people about their concerns, people have been telling us about how they have been turning down the thermostat, justi degrees can have a substantial saving on your energy usage during the winter. and also simple things like teaching your children about energy usage and how important it is to turn the light off, turn the lamp off. explain it to them. it light off, turn the lamp off. explain it to them.- light off, turn the lamp off. explain it to them. it is natural --eole explain it to them. it is natural peeple get _ explain it to them. it is natural people get frustrated. - explain it to them. it is natural people get frustrated. it - explain it to them. it is natural people get frustrated. it is - explain it to them. it is natural. people get frustrated. it is about education. _ people get frustrated. it is about education, and _ people get frustrated. it is about education, and these _ people get frustrated. it is about i education, and these conversations are very important, and if you are going to be able to reduce your

energy consumption, which is a key target of a lot of energy providers. they want to see consumers educate themselves, bring down their usage by 10—15% of themselves and really insulate yourselves against these high energy prices. let's talk about what the government has announced, that we are now effectively into operation today, this doesn't apply to northern ireland. this is england, wales, scotland. every house in britain will get a £400 discount on energy usage. the deductions will begin in october automatically on your bill. around £67 and £66 as we approach march and april. if you have a different type of income, a low—income household, disability and pensioners, there is an also extra cost of living support. the government has come through and provided a huge package of support to insulate

consumers against these huge price rises, which are a consequence of the russian invasion of ukraine and a real tightening and constriction on energy markets. the one thing to be careful about, consumer groups are warning this morning, even i got a text — a scam text — from groups saying "you are eligible for a discount on your energy bill under the energy bill support scheme. you can apply here." groups are saying this is becoming widespread and is a consumer scam. scammers want to get your personal details and try to swindle you. the advice is be very careful if you are receiving these types of texts. the support comes automatically through your energy provider. you don't have to do anything. you should not have to respond. if you are concerned, speak to your energy company, they are aware of it and are there to support. be careful with those scanned texts. protests against the rising cost

of living are taking place in cities across the uk this afternoon. the campaign group enough is enough organised the demonstrations, it was founded by trade unions and community organisations. people lined the streets to support rail workers, and criticise liz truss's mini budget, in cities including london, leeds, norwich and southend. laura dickinson is the yorkshire co—ordinatorfor enough is enough. a lot of workers and a lot of people working in this country have had enough, enough of working full—time and not being able to pay their energy bills and not being able to put food on the table. it is not just going to be these guys, other people in other sectors as well have had enough, and that is why everybody has come out in solidarity today, i think people can relate to it. royal mail workers have begun their second day of a 48—hour strike in a dispute over pay and conditions. the communication workers union says the walk—out by around 115,000 of its members is the biggest strike of the year. a royal mail spokesman described

the action as "reckless", saying it would weaken the company's finances and jeopardise workers' job security. ahead of the party conference in birmingham this weekend... liz truss has admitted that there has been "disruption" in the uk economy following the announcement of significant tax cuts in a mini budget eight days ago. her comments came at the end of a tumultuous week which saw the pound slump to an all—time low against the us dollar, and the bank of england forced to spend billions buying up government debt to prevent a potential collapse of the pensions industry. but the prime minister insisted her government had to act. 0ur political correspondent, jonathan blake, reports. meeting her danish counterpart outside number ten this morning, liz truss attempted to introduce larry the downing street cat. are you bringing back- austerity, prime minister? he didn't hang around, but questions continue about how she'll pay for her economic plans. in kent yesterday, the prime minister wanted to focus on the energy price cap

for households now in place. that hugely expensive move came before the not so mini budget, prompting political criticism and financial turmoil, which the prime minister acknowledged but played down. i recognise there has been disruption, but it was really, really important that we were able to get help to families as soon as possible. that help is coming this weekend, because this is going to be a difficult winter. and i'm determined to do all i can to help families and help the economy at this time. the chancellor's also trying to reassure. writing in the daily telegraph, kwasi kwarteng said the government had a plan to reduce debt, set new tax and spending rules, and publish full forecasts on the impact of all that on the economy. another senior minister, the levelling up secretary, simon clarke, has signalled spending cuts could be coming, saying there's always room to trim the fat. 0pposition parties worry what that could mean. we always support value for money,

but the turbulence in the markets has been caused by the government's own error ofjudgment in announcing a set of unfunded tax cuts that benefited primarily those earning over £150,000 a year. and it would be appalling now if, as a consequence of all that, they turned on pensioners, the disabled and those waiting on nhs waiting lists to pay the price for their own mistake. as the conservatives gather for their annual conference in birmingham this weekend, conditions are difficult for the prime minister, still new in the job and fighting to keep her party on side. jonathan blake, bbc news. and the prime minister will be interviewed live on bbc one tomorrow on sunday morning with laura kuenssberg. because of the london marathon, the programme begins at 8:30am. she will also have on the programme the shadow chancellor, labour's rachel

but with the redevelopment of the former steelworks, it had to come down. explosion 105,000 tonnes of steel brought down by more than 1.5 tonnes of explosives. applause and looking on, stuart and ken, father and son, both former steel workers, both former bos plant managers. it's gave a brilliant living to so many people in the area and beyond. and, you know, there is something sad about, i guess, losing it on that front. i mean, that is sad, but i am also well aware that we need to move on. steel— making is finished. we need to now develop this area. so, all the things that is happening with teesworks, taking this down and moving on is the best possible legacy. but will the hoped—for newjobs come to the site?

this last week has seen markets, companies and investors all spooked. well, i think we are uniquely placed that we have got the largest brownfield site in western europe, we have the uk's largest freeport with all the incentives that brings, we have got the site and support of government, as well, and actually that inoculates us from some of the international headwinds that we are seeing. so, the likes of net zero teesside, bp, who are all committed to the site, are not slowing down, they are still committing money as quickly as they can. it is seven years since the steelworks closed. today's blow down a dramatic reminder that those days have gone for good. ian reeve, bbc news. hundreds of thousands of homes and businesses are without electricity in south carolina in america, after hurricane ian hit the coast yesterday. it's the latest us state to suffer the storm. a huge clean—up operation is under way in florida.

some remarkable pictures came out from that state. at least 20 people died and many counties are without drinking water. we don't know the full picture in cuba where the storm first struck. let's get some of the day's other news. japan has criticised north korea for conducting more missile tests, which took place following a visit to the region by the us vice president, kamala harris. the launches defy a ban imposed on north korea by the un security council. tokyo says the missiles landed outside japan's exclusive economic zone, but there is concern pyongyang may be about to conduct a nuclear test in the coming weeks. ketanji brown jackson has made history by being sworn in as the first black woman to sit on the united states supreme court. as president biden's appointee, she joins two other liberals on the supreme court, which is dominated by six conservatives. she is seen here with the chief justice. the british singer phil collins and two of his bandmates from the rock group genesis have

difference will this protection status make? presumably in this country, hunting was a big problem and we had a fur trade, but putting and we had a fur trade, but putting a b for years it hasn't been an issue. ., a b for years it hasn't been an issue. . ., , , ., a b for years it hasn't been an issue. . . , , ., . ., issue. yeah, it has been a central chance issue. yeah, it has been a central change from _ issue. yeah, it has been a central change from an _ issue. yeah, it has been a central change from an animal— issue. yeah, it has been a central change from an animal that - issue. yeah, it has been a central change from an animal that was l issue. yeah, it has been a central. change from an animal that was not found in the uk to a protected species to a native species. it has always been a native species, but we haven't had that confirmed in centuries. in the last ten years, wildlife trust and others have been gradually bringing back beavers to the uk, so we released, the scottish wildlife trust working with edinburgh zoo released while living free beavers into south—west scotland. there is a trial to see if it is possible and for find that the population in the river otter in devon... they have been working with defra... we have a wild population in kent. interference

course in some cases they can cause issues. for example, if you have an arable crop on a flood plain and a beaver built a dam, that could flood. this can be resolved very easily. in mainland europe, the beaver has come back across the whole of mainland europe and have come back in numbers, every country in mainland europe pop in the uk. we can resolve the issues. what we have been trialling down in devon at the wildlife trust is voluntary beaver management groups which are simply a group of people who know what they are talking about and know how to deal with the issues as they arrive. what we have found on the river 0tter, as they arise, we deal with them quickly and sensibly and everybody is happy. bud them quickly and sensibly and everybody is happy. and particularly the beavers — everybody is happy. and particularly the beavers. thank _ everybody is happy. and particularly the beavers. thank you _ everybody is happy. and particularly the beavers. thank you very - everybody is happy. and particularly the beavers. thank you very much, | the beavers. thank you very much, due to talk to you. rob stoneman from the uk's wildlife trusts. which are operating and supporting this
