Motorists are facing severe delays on the M25 in Surrey after a multi-vehicle crash, according to traffic monitoring service Inrix.

The collision, involving three vans and a lorry, happened at about 06:55 GMT on Wednesday on the clockwise between junction 11 for Chertsey and junction 12 for Thorpe. One person was injured and taken to hospital, Surrey Police said.

National Highways said two lanes are closed with delays in excess of 90 minutes.

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

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 14 for Heathrow after two other accidents, while northbound traffic on the M3 is facing delays of about 25 minutes.

South East Coast Ambulance Service have been approached for comment.
