competition between companies. the competition and markets authority says it means those customers have paid around £900 million in additional costs. the government is now promising a change in the law to increase competition. our business correspondent emma simpson reports. filling up at the pump. we buy almost half of the appeal of the supermarkets because it is normally the cheapest but according to the regulator it may not be as cheap as it should be. i regulator it may not be as cheap as it should be-_ regulator it may not be as cheap as it should loo-— it should be. i think it is disgusting _ it should be. i think it is disgusting and - it should be. i think it is disgusting and they - it should be. i think it is i disgusting and they should it should be. i think it is - disgusting and they should be supporting us and not trying to make it worse. . , ., _, ., ., it worse. prices have come down a little but compared _ it worse. prices have come down a little but compared to _ it worse. prices have come down a little but compared to what - it worse. prices have come down a little but compared to what is - it worse. prices have come down a little but compared to what is to l it worse. prices have come down a | little but compared to what is to be like i_ little but compared to what is to be like iiusi _ little but compared to what is to be like ijust put in whatever i can. the watchdog found the gap has increased between what retailers pay for petrol and diesel and what they it for. ,, _, , ., it for. seen competition between retailers of _ it for. seen competition between retailers of petrol _ it for. seen competition between retailers of petrol and _ it for. seen competition between retailers of petrol and diesel - it for. seen competition between

in response to these findings? chris mason has more. they say they are shocked by this and concerned and they think that part of the solution is transparency. that is we are on the forecourt and we can see how much the fuel will cost exactly where we are, if we had an app to show us what it would cost down the road that would drive down prices but to do that, and there is a system along these lines already in place in northern ireland, that would require a new law but in the meantime mince say they want a voluntary scheme up and running as soon as next month. whether petrol providers volunteered their prices and they fell into a system and then as consumers we can see them. there has been a debate in parliament about this this afternoon and conservative mps representing rural areas experiencing particular price pressures where people are

very reliant on petrol and diesel. some concern about the amount of tax that the government takes from us filling up plus this and that transparency is all very well but if all it tells us that the fuel cost a fortune wherever we go there and how much use as that. and one final thought, i was struck today at the sense of lots of people blaming everyone else for this. you have the opposition party blaming the government commit government banning the supermarkets and the supermarkets say they are still competitive and they are often the cheapest. it seems that the reality is that when prices are high the stakes are also high for all kinds of folk here. if you look online you can find plenty of ways to save money on fuel — just go to bbc.co.uk. and if you want tips on how to save money on petrol and fuel go to our website. the met office has confirmed that this june was the hottest on record in the uk — with an average temperature

of 15.8 degrees celcius. of 15.8 degrees celsius. the previous record — ia.9 degrees celsius — was reached in both 19110 and 1976. higher than usual temperatures are one of the reasons that so many fish have been dying in britain's rivers and canals as our climate editorjustin rowlatt reports. they were scooping the fish out of this canal in their thousands on the weekend. it had been hit by another in an unprecedented series of fish death incidents, driven in part by the record high temperatures in june. the problem — oxygen levels in the canal have plummeted. it's an oxygen reader that's telling me it's1.7% oxygen when it should be 60% to 100%. it was like a carpet of fish across the canal. it felt like you could walk over them. it was unbelievable. so what's causing this? so here is what happens. as the water warms, it holds less oxygen. now, normally, fish can cope with that.

but if you also get a big storm, it washes in cold water and pollutants. now, that kills algae in the water. bacteria eat that algae. they flourish in their billions and they also take up oxygen. and that is when you can get these catastrophic collapses. thisjune didn'tjust edge ahead of previous temperature records, it smashed past them, according to the met office. so when you look back in the series that goes way back to 1884, the last time you saw anything close to that was way back in 1940 and 1976. what's staggering about this last month is the fact that it's about a full one degree above what we should be getting at that time of year. the met office says man made climate change made these record temperatures twice as likely. what's more, it says by 2050 we can expect every otherjune to be as hot as this one. forfarmers, that means a fundamental rethink of the crops they grow.

we'll be growing a more sort of mediterranean type crop than the traditional crops grown in this country. spring barley and spring wheatjust won't cope with a hot summer. and that could make some staple foods more expensive. the canal and river trust is using pumps to spray water to try and drive up oxygen levels. and they've tested the water for pollution. it is expensive and time consuming work and they have been dealing with an exceptional number of these incidents. it's unprecedented. six incidents last summer, 60 incidentsjust in the month ofjune alone. and so that is, you know, that's massively, significantly more. some fish have survived. they desperately gulp oxygen near the surface. but that brings a deadly new peril. swarms of seagulls are feasting on them.

said three important messages to date from the met office. we did not just break the previous record but we smashed it by huge margin and secondly that was made twice as likely because of man—made climate change. and by 2050 we can expect every other tune to be as hot as this one. those are findings that we should all profoundly worrying. there's fierce fighting in the city ofjenin in the occupied west bank — after israel launched one of its biggest military operations this morning. eight palestinians have been killed since israeli forces went into the refugee camp in the city in the early hours of this morning. israel said it had "dealt a heavy blow to terrorist organisations", but palestinians have accused israel of a war crime. 0ur middle east correpsondent yolande knell is injenin. by dawn, the battles had been

raging for hours injenin. the israeli military used a surprise drone strike overnight to target what it said was the headquarters of local militants. soon, armed palestinians were fighting back inside the city's crowded, decades—old refugee camp. hundreds of israeli soldiers on the ground. the israeli military says they are seizing weapons and explosives and that this is a hornets' nest for terrorism. there was a furious response from palestinian officials. what is going on is an attempt to raise the refugee camp completely and displace the residents, said the palestinian prime minister mohammad shtayyeh. palestinian medics have been struggling to reach the dozens of injured. israel says it is acting on precise intelligence and doesn't seek to harm civilians. but many have been caught in the crossfire.

what is going on in the refugee camp is all. there were strikes from the sky targeting it. every time we drive in with our ambulances we come back with injured people. irate drive in with our ambulances we come back with injured people.— back with in'ured people. we have runshot back with injured people. we have gunshot coming — back with injured people. we have gunshot coming from _ back with injured people. we have gunshot coming from the - back with injured people. we have gunshot coming from the refugee | back with injured people. we have - gunshot coming from the refugee camp just up on the hill. sometimes we also get loud explosions. the military has said that this is a closed sound and as journalists were not allowed to get closer but you can get a sense ofjust how intense the fighting is. in recent months many palestinians who have carried out deadly attacks on israel have come from this area. others have others have hidden here. and even before today, jenin has seen repeated deadly israeli army raids. israel says it doesn't want to expand this military operation to other parts of the west bank. 0ur our goal is to focus only on the

terrace themselves injenin. but already palestinian protests have reached the gaza strip. and the longer this action goes on injenin, the greater the risk of a dangerous, wider escalation. yolande knell, bbc news, jennin. a man who claims he was sexually assualted by the hollywood actor kevin spacey has described him as a "predator" and told a court in london today that he was groped so forcefully on one occasion while driving that he swerved across the road. kevin spacey is facing 12 counts of sexual assault against four men — which he denies. 0ur correspondent helena wilkison reports. kevin spacey, arriving at court for the second day of his trial, charged with 12 sexual offences, all of which he denies. today, thejury would hearfrom one of his four accusers. the actor, known for his 0scar—winning performance in american beauty, was also the artistic director of the old vic theatre in london between 2003 and 2015.

earlier, inside courtroom one, the american actor was back in the glass dock. he listened as the jury was played a recording of the accuser�*s police interview. during the police interview, the man described kevin spacey as a slippery, snaky, difficult person. he claimed the hollywood actor assaulted him up to 12 times. he said kevin spacey would touch him on and off and he described it as almost like grooming. the accuser also claimed that on one occasion, the actor groped him so forcefully while he was driving that he was forced to pull over. kevin spacey�*s accuser also came to court today to give evidence from behind a curtain. jurors were told it was so the witness could concentrate better on his evidence. under cross—examination by defence barrister patrick gibbs kc, the complainant said he felt ashamed about what he alleges kevin spacey did to him.

the accuser told the court, i would make it crystal clear i don't like that, and don't do it again. he accepted he kept the alleged incident secret. mr gibbs kc asked him what emotions he had over time. a mixture — ashamed, embarrassment or shock, the complainant answered. kevin spacey leaves court after a day of hearing evidence from a man he was accusing him of serious sexual offences, allegations the actor denies. the trial is expected to last four weeks. helena wilkinson, bbc news, at southwark crown court. our top story this evening. it has been revealed to drivers who bought their fuel from a supermarket for court last year paid an extra 4p per litre because of lack of competition between companies. and coming up a special report on how ukraine's counteroffensive is being hampered by russian landmines.

and on bbc london, why some landlords are being forced to sell up landlords are being forced to sell up making it harder to find a property to rent in london. and rail passengers fake a waste of disruption due to industrial action by some train drivers. —— face a week of disruption. last year a record 25,000 people came forward last year to raise concerns about failings in the nhs — but some say speaking up has had serious implications for their careers or mental and physical, health. the national guardian for the nhs — whose job it is to protect whistleblowers — says nobody should suffer for doing the right thing. and the man who led the inquiry into hundreds of patient deaths at stafford hospital more than a decade ago says whistleblowers should be better protected. our health correspondent dominic hughes reports. all of a sudden you know who your friends are. tristan, a senior eye surgeon in birmingham, became a whistle—blower when he complained about a lack of nursing staff.

he says he felt forced to use a non—medical colleague to help with an urgent operation. the trust says he jeopardised patient safety. he was sacked and reported to the general medical council. they found no case to answer and an employment tribunal ruled he'd been unfairly dismissed. there must have been a terrible emotional burden. it was pretty bad, and at times i thought, this is the end of it. it's tough. it is tough. yeah. we've spoken to doctors who've said they thought about ending it. i've had those thoughts. a spokesperson for university hospitals birmingham says the trust takes safety concerns raised by staff seriously and had accepted and apologised for errors made in mr reuser�*s case, but said it acted

in the interest of patient welfare. the nhs in england employs what are called freedom to speak up guardians to help whistle—blowers get their voices heard. the system was set up in the wake of the mid staffs scandal nearly 20 years ago that saw hundreds of patients die as a result of poor care. it starts with a failure to look into things seriously when they're first raised. sir robert francis investigated mid staffs and recommended the creation of the guardians, but he's not sure the protections for whistle—blowers are enough. are you confident the system as it stands is enough to prevent another catastrophe like that? am i confident? 100%? no. there is a danger of it happening again when pressures similar to those that existed at the time of mid staffs come about. but i think the way to stop it is to think all the time about the culture and make sure you've got an open culture, a supportive one, and one that by treat the patient first,

by listening to the staff's concerns about them. the mid staffs scandal was exposed in part thanks to a whistle—blower, but speaking up takes real courage. what's been really difficult about making this film is finding whistle—blowers who are willing to talk to us on camera. now, i've spoken to a number of people who work for the nhs and they're all worried about the impact that speaking out might have on their careers, their livelihoods. and they all talk about a climate of fear. paul is one of those who was willing to talk, but he too has paid a heavy price. i've been medicated for anxiety and depression for well over two years now as a result of whistle—blowing. a former police officer, paul worked for the north east ambulance service, liaising with the coroner's 0ffice. he went public when he discovered vital details of deaths were being deleted from official reports. he says raising those concerns led to months of harassment and stress.

i would describe the culture at the north east ambulance service as toxic, where staff are bullied, where mistakes are covered up. it's a cover—up culture. it's not a good place to be. it's certainly not conducive with patient safety and staff safety. north east ambulance service told us the trust was grateful to paul for raising his concerns. while it admits flaws in processes, it denies any deliberate attempt to cover up patient safety issues. nhs england says it wants all employees to feel they work in an organisation where their voices count. but it admits there are still too many staff who don't feel safe enough to speak up. dominic hughes, bbc news. investigation into the fire... an investigation into a fire which killed a mother and two

into a fire which killed a mother and two children in cambridge on friday has concluded that it was probably caused by an e—bike which was being charged in their home. the fire service is now urging people to avoid charging e—bike or e—scooter batteries overnight. 0ur correspondent simon jones is in cambridge. the fire broke out here in the flats behind me in the early hours of friday morning. it claimed three lives. gemma, who was 31, died here at the scene and her two children died later in hospital. lilly, aged eight and all of four. the fire service say throughout the course of the weekend they have carried out a painstaking investigation which is also involved officers from the police but the conclusion is the fire was started accidentally and the likely cause, according to emergency services, was an electronic bike which was being charged. pl. electronic bike which was being charred. �* , ~ ., electronic bike which was being charred. �* , ~' ., ., charged. a e-bike will have a lithium ion _ charged. a e-bike will have a lithium ion battery _ charged. a e-bike will have a lithium ion battery the - charged. a e-bike will have a lithium ion battery the same | charged. a e-bike will have a l lithium ion battery the same as charged. a e-bike will have a - lithium ion battery the same as on an e skater or a mobile phone, most devices have them in a range of different sizes. and if they get too

a flimsy pontoon bridge as we head towards ukraine's southern front. in a landscape blasted by artillery and rocket fire, a different danger now faces ukrainian troops as they fight to recover territory. russian mines. they're everywhere. soldiers stumbling across yet another on the roadside. is it a claymore? and it's still live? this is a claymore mine they've just discovered, still active, so i think we need to probably move away. well back. as we pull back, ukrainian engineers move in cautiously to defuse it. "detonate it," he says, "and you're talking about 30 or a0 casualties." "there are mines everywhere," says dimitro. "they scare me more than anything else. "two of our most experienced men

lost a leg each this week." grim drone footage of a ukrainian unit trapped in a russian minefield. medics already treating several wounded men. then, this soldier steps on another mine but, somehow, clambers to safety. we are having to be very careful where you walk here. a lot of russian mines left behind and in the fields along the front lines, vast acres of russian minefields. and it's because of those mines, ukrainians say, that they are struggling to make the kind of strategic breakthrough they need to in order to change the course of this war. a ukrainian engineer shows some of the russian devices he's disarmed. both sides are accused of using banned antipersonnel mines.

in his bunker, a ukrainian commander tells me the counteroffensive is on course, but going slowly. "that's because unlike the russians, we are trying to keep our casualties to the minimum," he says. but could a ukrainian breakthrough be imminent? intercepted russian radio messages hint at collapsing morale. "50 of our men ran away," this russian soldier is caught saying. for ukrainian forces, every step forward here remains a risk. but they are advancing through the minefields nonetheless, filming themselves as they liberate their country, field by field, trench by trench. andrew harding, bbc news

in eastern ukraine. here, rail commuters face disruption this evening as train drivers refuse to work overtime from today until saturday night, in their latest long running dispute over pay. this morning aslef announced another overtime ban for its members from the 17th to the 22nd july. most train companies rely on drivers working on " rest days' to run their full timetables. this action will affect 15 operators based in england. a cabinet office inquiry has found the official who led the investigation into lockdown parties at downing street broke the civil service code as a result of "undeclared contact" with the labour party. sue gray was cleared to work for labour by parliament's advisory appointments body last week. labour said the cabinet office's findings were a "political stunt" by the conservatives. day one of wimbledon and the defending men's champion novak djokovic is bidding for his eighth singles title. big crowds and already some rain. our sports correspondent andy swiss

is there and sent this report. will the stewards please open the gates. for tennis fans, the long wait was over. well, almost. wimbledon is where the world's greatest players are watched by the world's greatest queuers. but with security heightened because of concerns over protesters, simply getting in was a test of stamina. after six, seven hours of thousands of people standing in the same field, it's got a bit hectic. the toilets especially. they are not flushing any more. whatever process they've had for their security checks hasn't been effective because you shouldn't have these type of ques. i got in after nine hours. i got in after nine hours! and it wasn'tjust the fans getting delayed. novak djokovic is chasing a record equalling eighth men's singles title here, but against argentina's pedro cachin, he soon found his touch.

and that is the end of the first set. but barely had he won that first set... ladies and gentlemen, play suspended. 0n came the covers but for all their efforts the court was left slippery and drying it out proved a problem. djokovic even tried using a towel before an army of what looked like giant hairdryers arrived. ebike batteries at home but the near hour break in play challenged everyone's patience, so when play finally resumed, no surprise djokovic seemed in a hurry. his 29th win in a row at wimbledon. you suspect there may be a few more to come. in the women's singles meanwhile, top seed iga swiatek was taken safely through beating china's zhu lin in straight sets, and in the last hour, a first british victory at the championships asjodie burrage beat katie mcnally. and if you wondered what it means to win at wimbledon, well, there's your answer.

yes, and there has since been a second british winner here with liam broady also safely through. but we have real drama on centre court. venus williams, now 43 years old. she has had a nasty looking fall in the heart match but is battling on against svitolina. the heart match but is battling on against svitolina. if you have clear skies tonight — if you have clear skies tonight — look up — because you'll have a good look up — because you'll have a good chance of spotting the biggest chance of spotting the biggest and brightest moon and brightest moon of the year so far. of the year so far. this was the �*full buck�* this was the �*full buck�* supermoon rising last night. supermoon rising last night. it will be at the closest point it will be at the closest point in its orbit around earth, in its orbit around earth, making it appear larger and brighter making it appear larger and brighter in the sky. in the sky. and the man who can tell us if we and the man who can tell us if we are going to see it as stav danaos. are going to see it as stav danaos. not a bad start to the night but not a bad start to the night but then things turn cloudy. we had some then things turn cloudy.
