Motorists are facing severe delays on the M25 in Surrey after a multi-vehicle crash forced the closure of three out of four lanes on the clockwise carriageway.

The crash happened at about 06:55 GMT on Wednesday between junction 11 for Chertsey and junction 12 for Thorpe. One person was injured and taken to hospital, Surrey Police said.

National Highways said just after 09:40 all lanes had reopened but there were still delays of about 60 minutes.

Inrix reports congestion is stretching as far back as junction eight for Reigate.

A spokesperson for South East Coast Ambulance Service said they were called to reports of a multiple vehicle crash between junctions 11 and 12.

"Crews including a critical care paramedic attended the scene where a male patient was assessed and treated for a leg injury," they said.

"He was then taken to St George's Hospital in London for further medical treatment."

Traffic is "extremely heavy" through Chertsey, Addlestone and Weybridge, with some drivers diverting via Esher and Thames Ditton, Inrix says.

Queues are also reported on the opposite carriageway as far as junction 13 for Staines after two other accidents, while northbound traffic on the M3 is facing delays.
