Thousands of drivers are suffering severe delays after a Tesco lorry crashed and burst into flames on one of the UK’s busiest motorways.

National Highways said the clockwise carriageway of the M25 between Junction 5 in Kent and Junction 6 in Surrey is likely to remain closed for the rest of Monday.

This is causing delays of two-and-a-half hours, with congestion stretching for four miles.

The crash happened in Surrey between Clacket Lane service station and Junction 6 at around 10pm on Sunday.

The driver sustained minor injuries, according to Surrey Police.

Five fire engines and two water carriers were sent by Surrey Fire and Rescue Service to extinguish the blaze.

Firefighters remained at the scene until around 8.40am on Monday, at which point the lorry was a blackened shell.

National Highways said removing the lorry would involve specialist equipment, and the road is likely to require resurfacing.

The incident has also closed the M26 westbound between Junction 2A and the M25/A21.

Meanwhile, a closure of the northbound east tunnel of the Dartford Crossing between Kent and Essex was also expected to continue throughout Monday, after a maintenance vehicle broke down and caused a large spillage.

This also resulted in the need for emergency resurfacing works.
