Witness appeal following serious collision on the M25 near Bletchingley

We are appealing for witnesses following a serious collision on the clockwise carriageway of the M25 between Junctions 6 and 7, near Bletchingley, shortly before 10am today (Wednesday 24 June).

The collision involved a white Mercedes Vito van and a white lorry. The driver of the van, a man in his 30s, sustained serious injuries and was treated at the scene before being taken to hospital by air ambulance.

The M25 clockwise carriageway between Junctions 6 and 7 remains closed while emergency services and National Highways continue their response. One of the vehicles is currently being recovered, and a significant oil spillage from the collision has caused damage to the road surface. National Highways engineers are carrying out assessments before the carriageway can safely reopen.

Both lanes of the exit slip road at Junction 6 are now open, allowing motorists to leave the motorway and rejoin at Junction 6 if required. Traffic is being diverted via the M26 and local road networks. Drivers are advised to continue avoiding the area where possible and to follow National Highways and local travel updates for the latest information.

Our enquiries remain ongoing, and we would like to hear from anyone who witnessed the collision or has dashcam or helmet-cam footage that may have captured all or part of the incident. Anyone with information is asked to contact us, quoting PR/45260075072.

We would like to thank motorists for their patience and understanding while emergency services responded to the incident and road closures remained in place. We are also grateful for the continued support of our partner agencies, including Surrey Fire and Rescue Service, South East Coast Ambulance Service, Air Ambulance Kent Surrey Sussex and National Highways.
