There are severe delays on the M25 this evening.

Two lanes are blocked due to an overturned caravan Northbound between J2 and J1, Sunbury.

There is a several mile traffic build up anticlockwise, stretching from J1 A282 at Swanscombe to J4 at Orpington.

This follows significant delays caused by an overturned lorry near Leatherhead this morning, which closed the motorway for eight hours.

An eight mile traffic build-up was reported, which is still yet to fully clear.

Surrey Police said the lorry driver was taken to hospital by air ambulance, with life-threatening injuries.

The occupants of the other vehicles were uninjured.
