A toxic smog will hit parts of Britain tomorrow as councils continue to deal with roads melting and rail lines buckling amid soaring temperatures, with workers facing a commute in the hottest June day since 1976.

Tarmac has been turning into a liquid mess in Surrey, Cambridge, Manchester and Lancashire today with highs of 91.5F (33C) but tomorrow will be even hotter, as temperatures soars to 93.2F (34C).

And now parts of the country will face increased air pollution as the Department of Environment, Food and Rural Affairs (Defra) predicts rates of seven to eight out of their scale of 10 in some areas on Wednesday.

The soaring temperatures have sparked battles between bosses and employees, with one man who turned up to work in shorts, but then changed into a dress when he was ordered home.

Parents have vowed to keep their children at home as school heads have refused to relax strict uniform rules despite the punishing heat.

The hot weather has promoted some strange behaviour too, with a Range Rover driver, who perhaps hoped to mimic a TV advert, found his £70,000 luxury 4x4 stuck in mudflats amid the rising tide.

Daredevils in Dorset took basejumping to the extreme after leaping 150ft off the iconic Broadchurch cliff in West Bay, and landing just yards from families on the beach.

iPhone melts after it's left in direct sunlight for an hour The soaring temperatures were hot enough to wreck the insides of the smartphone beyond repair (pictured) A warning was issued yesterday after an iPhone melted in the scorching heat. The soaring temperatures were hot enough to wreck the insides of the smartphone beyond repair after it was left exposed in direct sunlight for an hour. The unnamed owner reportedly left the 6S model unprotected when she stopped for food at a cafe in Cornwall. When she found it had stopped working she took it to a local repairman who said it was a write off. Dave Gilmore, of Wadebridge, Cornwall, who has been repairing phones and computers for a decade, said it was the most damaged he had seen. He said: 'It was a girl who had been out walking, had stopped for lunch, and the phone was on the top of her bag. 'It's the worst damage of this sort I've seen, it has melted the screen connectors and has even melted the camera as well. To be honest, I think the phone is a complete write off.' Other users have been advised to keep phones out of direct sunlight. One said she got a warning message on her iPhone saying she could not use her device until it cooled down. She said: 'If you're out and about, keep your phone in your pocket or in a bag - or you may be in for a very expensive lesson.' Advertisement

Toxic smog to spread in Britain Tomorrow, parts of the UK will face high levels of pollution. According to Defra, most of England, away from the northeast, and also Wales are expected to have Moderate levels of air pollution during Wednesday. Again there is a small risk that some extremely localised areas of High pollution will occur. Areas of Moderate air pollution are also possible across parts of Northern Ireland and Scotland, where otherwise the pollution levels should be Low. While the general population will be fine in moderate levels, those with lung or heart problems should consider reducing their levels of strenuous outdoor activity. In high levels, those with lung and health problems should reduce outdoor activities. Anyone who experiences symptoms like a sore throat should also reduce outdoor activities. Advertisement

Emergency roadworks are being carried out across the country as Cambridgeshire council even brought out the gritters to help.

Agnes Owen, who works at a service station, said that it 'sounded like cars were driving on water'.

She said: 'The tyres were literally ripping the tarmac off the road. It's quite dangerous!'

Evan Laughlin, from Cambridgeshire County Council, says that 'normally the roads can stand the temperatures'.

But he added: 'They're surface dressed roads and what's happening is the binder that's underneath the stone that you see is bleeding through - the heat is bringing it to the surface

'We're using the gritters to apply granite dust which settles it down and stops the bitumen material applying itself to the wheels of vehicles.

'It's very expensive to use other processes to resurface roads. It's a very good product that we use.

'The road surface temperatures are at 40C (104F) and above at midday. Normally the roads stand the summer temperatures we get, but just this week it's very hot.'

Hundreds of supermarket customers are missing out on their shopping as Tesco's system went 'into meltdown'. Those avoiding roads are likely to be sweating on trains using newspapers as makeshift fans.

To add insult to injury for hundreds of families, supermarket chain Tesco has cancelled orders after an error, leaving them without ice cold drinks and ice cream, with store freezers bare as Britain desperately tries to cool down.

The five-day heatwave, which is likely to hit its peak tomorrow with temperatures of 93F (34C) expected, will bring rain at the weekend, but festival goers need not fear, as Glastonbury will probably escape the worst.

In Cambridgeshire today, motorists were spotted driving cautiously along a road in Doddington where the Tarmac has melted.

Teenager drowned in reservoir as he cooled off in sunny weather Tributes have been paid to a teenager who drowned in a reservoir as he tried to cool off with friends on the hottest day of the year. The youngster, who has been named on social media as Paul Lawson, went missing around 6pm on Monday at the Greenbooth Reservoir, a moorland beauty spot outside Rochdale, Greater Manchester. He had reportedly got into difficulties while swimming with friends as temperatures soared above 91F. The teenager had been underwater for five minutes when police were called at 5.55pm. The heatwave claimed another victim after an elderly woman was pulled from the sea. The woman, thought to be in her eighties, was pulled from the sea at East Witterings at 2.40pm on Monday.

Repairs are now being carried out on the road as England looks set to see the hottest June for decades. Drivers were also warned to take care on the B1165 near Newton in Cambridgeshire, where the tarmac has melted.

In Tarleton, Lancashire, one driver found out the hard way that the roads were melting, as he found himself scraping a sticky mess off his shoes.

The man, who didn't want to be named, took the snaps in Tarleton, Lancs., and was frustrated to discover tar all over his wheels and his own shoes - which he then transferred to the inside of his car.

He said: 'It was unbelievable. It went everywhere - even on the pedals inside your car. I dread to think what the road would be like in the winter if it stayed like this.'

The streets are so warm that a passerby was able write the word 'hot' in the floor on Castlefield, Manchester.

A commuter in Croydon decided to skip the tram after she spotted what she believed to be tarmac melting, and heard the trams making a 'grinding' noise as they went over them.

Photographer Sarah Preece was walking to a local market when she saw the black seal around the tracks had started to melt - near where seven people died in the horror Croydon Tram Crash.

Sarah noticed the fault around 3pm on Monday - the hottest day of the year - near Lebanon Road tram stop in Croydon, south London.

She said: 'I noticed that each time a tram went over the tracks that the damage worsened, and the trains made a loud grinding noise as it went over.

'I walked down to East Croydon, and again the tracks were damaged. I contacted TfL and asked 'Is this even safe?'

But the 'melting' track is just the flexible sealant, which gives no structural support, and provides a movement joint between the rail and the tarmac.

Rory O'Neill, TfL's Director for London Trams, said: 'The flexible sealant near the track has been softened by the current hot weather and although it is having no impact on the safe running of the tram network, we appreciate it may look concerning to customers.

'Our engineers are on site and, as is standard procedure, they are applying sand to mitigate the effect of the heat.'

Yesterday there were transport problems caused by the weather being too hot for trains to run normally, while today, London commuters sweated it out in the heat of the underground.

In the south-east almost 50 trains were cancelled and dozens delayed because of the risk of tracks buckling in direct sunshine.

Glorious sunshine to end in storms (but don't worry if you're going to Glastonbury) Temperatures are expected to peak at 34 on Wednesday, the hottest June day since 1976 and then drop off with the arrival of thunderstorms. Forecasters are predicting torrential downpours through to early Thursday morning with 40mm (1.6 inches) of rain expected to fall in an hour in some places. The storms will bring the longest heatwave since 1995 to an end and mark the end of what is likely to be one of the hottest months since records began in 1847. Met Office spokesman Oli Claydon added: 'Glastonbury will get away with it as the south west is likely to remain dry.' Advertisement

Greater Anglia said slow speeds meant some services were cancelled between London and destinations including Norwich, Ipswich and Southend.

Great Western Railway also had delays due to speed restrictions on routes between London and the west country.

Network Rail said: 'Rails in direct sunshine can be 20C hotter than air temperature. Rails expand as they get hotter and can start to buckle. 'Speed restrictions are imposed as slower trains exert lower forces on the track, reducing the chance of buckling.'

The problems prompted criticism on social media.

Traveller Andrew Barnard tweeted: 'Wrong type of heat Greater Anglia? It's 2017, not 1917.' And retired policeman Paul Cater tweeted: 'It's officially too hot for trains to run.'

Some roads in Lancashire were also said to be visibly melting in the sun, with warnings issued about avoiding certain roads.

There was also reports a road surface melting near Guildford, where spilt oil had 'melted into the tarmac due to the heat', according to Surrey Police.

But the hot weather has also led to tragedy, with two people dying as a result of the extreme heat.

One teenager, named on social media as Paul Lawson, drowned in Greenbooth reservoir on Monday evening, after diving into the water to cool down in the hot weather.

He got into difficulty when he was with friends at the beauty spot outside Rochdale, Greater Manchester and had been under the water for five minutes when police were called at 5.55pm.

A woman in her 80s also died after being pulled from the sea at East Wittering beach in West Sussex on Monday afternoon, Sussex Police said.

'Idiot' teenagers cool off by tombstoning in Devon Thrill-seeking teens have been branded idiots after they cooled off by dangerously tombstoning from a pole into the sea. Local councillor Stuart Hughes took pictures of reckless teenagers taking turns to jump off a pole just yards away from sheet piling concrete on Monday night in Sidmouth, Devon. They leapt around five metres to the sea and Mr Hughes said they were lucky not to have been seriously injured. He said: 'These youngsters appear to be blind when it comes to dangers that this type of activity poses. Teenagers were filmed flinging themselves off a pole in the sea in Devon, sparking warnings over safety, as they could not have known what was in the waters below them 'They are unaware of all the nasties that lay on the bottom of the sea bed around this post which is there to warn sailing boats of the outfall wall. They have no sense of danger below the waterline and taking tombstoning to next level at Sidmouth. 'As you can see, there are some real nasties with sheet piling around concrete in fill. Fall off the top and hit this you would do some real damage to yourself. I just couldn't believe what I was seeing.' Tombstoning sees people jump from high structures - such as bridges or cliffs - into the sea. In the past six years there have been 16 deaths and 50 serious injuries related to the craze. HM Coastguard said: 'We always urge people to have fun but stay safe when out enjoying our beautiful beaches and coastlines. 'Jumping from piers, cliffs, rocks or other structures into the sea can be very dangerous. 'The depth of the water can dramatically change with the tide, and what was a deep pool at lunchtime might be a shallow puddle by teatime. 'You don't know what hazards may be lurking under the surface until you are hurt or worse.' Advertisement

The extreme heat - which is currently warmer than the 89F (31C) temperatures seen in the Maldives, Crete and Sicily - has prompted the Met Office to issue the second highest heatwave alert for all of Britain, while NHS bosses have urged residents to shelter from the sunshine.

The level three amber heatwave warning is one behind a national emergency and has been issued from 9am Monday to 9am Thursday.

The warning is issued when 'there is a 90 per cent probability of heatwave conditions' according to the Met Office website.

The heat did not subside overnight either, as people struggling to sleep flocked to Twitter to share their tips and frustrations, with the hashtag #toohottosleep.

Some discarded nightwear completely to strip off and sleep in their birthday suits, others turned a bag of frozen peas into a makeshift icy pillow and al fresco sleeping - basically giving up and bedding down in the garden, also proved a popular choice.

Some nervous sleepers admitted they didn't like nodding off without a sheet or duvet on top of them, so were forced to spend the night thrashing about in the balmy conditions - but at least safe in the knowledge that no monsters would get them.

Others admitted the unusually clement weather had taken them by surprise - and wished for the showers and grey skies they were more used to.

Some may have found themselves jealous of their pets who could leap into the fridge for some respite from the soaring temperatures

Twitter users joked about planning rain dances to help quell the heat, while others said they couldn't sleep without their duvets or the monsters would get them

The heat means social and healthcare workers should ensure high-risk groups including the elderly, children and those with medical conditions, are kept cool and hydrated.

It has led unions to call for more relaxed dress codes for workers, urging bosses to let people come in to their workplaces in shorts and flip flops instead of suits, and even consider sending them home if it gets above 86F (30C) - or 80F (26.6C) for those doing strenuous work.

Man sent home from work for turning up in shorts comes back (...wearing a bright pink dress!) While on his way to work Joey Barge, 20, from Buckinghamshire, tweeted: 'If women can wear skirts/dresses at work can I wear smart shorts like so?' Just minutes later he was sent home by bosses who thought his attire wasn't appropriate for the office despite the sweltering heat. But rather than changing into a stuffy suit, the call centre worker decided to don a bright pink dress as a 'protest' against the rules.

The TUC has also called for employers to implement cooling measures when a workplace temperature reaches 24C.

The organisation said that companies should supply workers with cool drinks and allow them to take regular breaks.

TUC general secretary Frances O'Grady said: 'While many of us will welcome the sunshine and warm temperatures this week, working in sweltering conditions can be unbearable and dangerous.

'Employers can give their staff a break by relaxing dress code rules temporarily and ensuring staff doing outside work are protected.

'Obviously shorts and flip flops won't be the right attire for all workers, but no-one should be made to suffer unnecessarily in the heat for the sake of appearances.'

One worker gave it a go in Buckinghamshire, changing into a summer dress when he was sent home for wearing a pair of smart shorts.

While on his way to work Joey Barge, 20, from Buckinghamshire, tweeted: 'If women can wear skirts/dresses at work can I wear smart shorts like so?'

Now that's an off-roader! Coastguard to the rescue after hapless Range Rover driver is gets his £70,000 luxury 4x4 stuck in mudflats This is the moment a hapless motorist tested the off-road capabilities of his brand new £70,000 Range Rover - and got stuck on mudflats. The young man was apparently copying TV adverts of the 2017 Range Rover Sport when he drove it onto the sand at Weston-super-Mare, Somerset. But he got bogged down in the treacherous mud 400 metres from the shore and was forced to call for help at 6pm on Monday evening. The young man ignored warnings signs and ventured out onto the sand at Weston-super-Mare in a 2017 Range Rover Sport but got stuck The RNLI was called in to rescue, and managed with just minutes to spare before the tide engulfed the luxury motor. The coastguard warned not to put their vehicles at risk A hovercraft from Burnham Area Rescue Boat was dispatched to the stranded 2.5 tonne vehicle with two Coastguard 'mud technicians' on board. They battled in vain to dig out the tyres with spades and eventually an RNLI tracked launching vehicle was used to pull the 4x4 free. The rescue was completed with just minutes to spare before the incoming tide engulfed the luxury motor. A Coastguard spokesman said: 'The driver of the Range Rover was a young man who had attempted to test out the vehicle, having watched TV adverts of it being driven off-road - but without realising how dangerous the mudflats can be. 'Our advice to motorists using local beaches is never to put their vehicles at risk by driving beyond the hard sand at the top of the beach.' It is believed the occupants of the Range Rover abandoned it before the hovercraft reached them and the vehicle did not suffer any serious damage. Advertisement

Predicting that he'd be sent home again, Joey posted a fashionable selfie to Twitter which racked up dozens of likes and retweets.

Instead his act of defiance sparked a change in the rules - with bosses sending out an email allowing 'gentlemen in the office' to wear three-quarter length shorts in 'black, navy or beige only'.

The EU yesterday revealed that officials in Brussels could go home early if they get too hot despite tough Brexit negotiations kicking off.

Eurocrats have been told they can leave if office temperatures hit 86F.

In a notice circulated to staff and posted online today, the EU's HR departments also advises staff to turn the lights off to keep cool.

Even too hot for foxes! Cunning animal takes a break from the heat Martin Besserman snapped a fox relaxing when he went to use his sunbed only to find he had been beaten to it. The 50-year-old comedy promoter, who lives in north London, said: 'I went out into my garden on Sunday morning at about 10:30 because it was really hot and I just wanted to relax, but the fox got there before me. 'They're regularly near the house, I opened the window a little bit to get the photo and the fox acknowledged it but wasn't frightened. 'These foxes are less afraid of people than usual, it's curious really, they seem to be quite confident. 'I saw another one on Monday morning about 6am, there was one sleeping on the wall, and on Saturday morning there was a whole family of them there climbing on the sunbed. 'I have seen more foxes than usual near my house, but there's been a bit of anxiety because next door have a cat. 'There's a dilemma about allowing them to stay there in case they got in a fight with it, I saw one of them trying to get the cat's food a couple of weeks ago.' Advertisement

And they suggest employees should ditch their suits and ties and opt for loose-fitting clothes to cope with the heatwave.

The circular points out that staff should open windows, drink lots of water and 'not to drink alcohol' during the hot weather.

They also suggest Eurocrats should not indulge in a lavish lunches and instead opt to 'eat light meals' while the mercury is soaring.

Yesterday became the hottest day of the year so far as the temperature reached 91F (32.4C) at RAF Northolt, west London.

The temperatures beat the previous record for this year, the 89.8 F (32.1 C) reached on Sunday.

But forecasters say it could be even hotter tomorrow, with highs of more than 96.2F (35.7C) anticipated. The highest June temperature since Met Office records began was recorded in Southampton on June 28, 1976 when it was 96F (35.6C).

The NHS has also issued advice and guidelines on the www.nhs.uk website to help people deal with the blazing sunshine.

NHS advice includes urging people to: 'Spend time in the shade when the sun is strongest, between 11am and 3pm.'

It also said: 'Keep rooms cool by using shades, have cool baths or showers and stay hydrated.'

In Birmingham city centre, Semia Elahcene and her daughter Sofia cooled off in a fountain as they desperately tried to cope with the soaring temperatures.

In Hampshire, a tiny harvest mouse was snapped feasting on pollen after nestling itself inside tulip buds. The cute mouse - around the size of a two pence piece - climbed up the stems of the colourful flowers and jumped inside the petals.

It quickly obtained the pollen before moving on to more tulips, while being photographed by accountant Val Saxby as it did so. Ms Saxby, 56, took these photos at Libertyís Owl, Raptor and Reptile Centre near Ringwood, Hants, and said the mouse was 'endearing'.

One mother even kept her children home from school as the annual battle over children wearing blazers raged online on Mumsnet.

Sabrina Fitzsimons, from Bournemouth, refused to send son Jack, 14, and daughter Caitlin, 15, to Winton and Glenmoor schools because of the blazer policy.

'Blazers in this weather?' Mumsnet rages at school uniform policies as one mother keeps her kids HOME Sabrina Fitzsimons, from Bournemouth, refused to send son Jack, 14, and daughter Caitlin, 15, to Winton and Glenmoor schools because of the blazer policy. 'In this heat, children are expected to wear their blazers and I feel this poses a significant risk to their health,' she said. She decided to keep them at home after Caitlin complained of headaches and nausea due to the heat last week. She phoned reception yesterday morning for the policy on blazers and said she was told pupils are expected to wear their jackets at the school. She said: 'Teachers decide if students can take off their blazers in class - but the teachers are in their light clothing dictating to the pupils that if they remove their blazers they face isolation. 'How is this even allowed? Surely it is the school's responsibility to ensure the safety and well being of pupils?' Another Mumsnet user vented her frustration after her younger sister was forced to continue to wear her school blazer in spite of the blistering heat. User Kitbee raged that she was 'f***** off' that the teenager was being forced to dress in a full school blazer with her shirt done up to apparently instill a 'work ethic'. She wrote on the parenting site: 'Blazers on in this a weather. Really? Top buttons too. DSis [darling sister] school is saying it's to enhance work ethic and get you use to the work place by following rules like these.' Advertisement

The high temperatures are forecast to stay for most regions until cooler conditions move in on Friday.

Meanwhile, police across Britain also urged dog owners to leave their pets at home, amid reports of dogs being rescued from hot cars.

In St Ives, Cornwall, a local resident smashed a car window to help a dog who appeared to be dying of overheating. Clive Oxley called police and was warned he could be arrested for criminal damage.

He said: 'We just smashed it and got it out and gave it some water. At least it can breathe now - it was lying on its back with its leg in the air.'

In Hornsea, East Yorkshire, police officers rescued a distressed dog by smashing the window of a car just in time. The owners were reported for animal cruelty.'

Age UK also urged everyone to 'look out for older neighbours, friends and relatives' and issued detailed advice about how the elderly can cope with the hot conditions.

Dr Angie Bone, Head of Public Health England's Extreme Events team, said: 'Spells of hot weather like this are enjoyed by many of us, but they can make a very real impact on some people's health.

'That's why it's so important we all keep an eye on those likely to be most at risk, people with underlying heart and lung conditions, older people and those with younger children.'

MeteoGroup forecaster Callum Stewart said: 'We can expect more warm and humid nights this week as the very warm weather will remain until Friday.'

Soaring temperatures start a cheeky craze as social media strips off

A cheeky craze has taken off with the soaring temperatures - of people baring their bottoms across Britain.

The sizzling sunshine has seen men and women uploading photos of their backsides to an Instagram account called Cheeky Exploits.

It is dedicated to 'making the world happier through butts' and shares photos of people exposing themselves in places around the world.

Some of Britain's best known places feature in the gallery and the heatwave has seen an upsurge in activity. The latest shots includes two blondes frolicking in an unnamed forest with their rear ends on full show.

In another a woman lifts her skirt at a farm while one man showed his bum at London's Regent's Park. Other recent posts include half naked golfers and scuba divers. One of the most daring includes a buttocks-only shot at famous Durdle Door on the Dorset coast.

The woman had pulled down her trousers and underwear from the rear while facing a group of unsuspecting people.

Another shows a completely naked woman from the rear with arms outstretched at Hope Cove in Devon while a fully nude woman is also seen standing among the gorse on the clifftop in nearby Salcombe.

Other more daring shots have also been taken in London's Hyde Park and Kensington Gardens.
