A woman has been left with life-threatening injuries after a crash between a van and a camper van on the M25.

It happened at around 11.20am today on the M25  close to the junction with the M40, between junction 16 and 17 on the clockwise carriageway.

A silver Ford Transit van and a red Citroen Berlingo camper van crashed.

A woman in her forties, who was in the camper van, was taken to hospital with life-threatening injuries.

Her next of kin have been informed.

The driver of the Transit van was not injured.

Investigating officer Sergeant Matthew Cadmore of the Roads Policing Unit based in Taplow, said: “Although the roads were not as busy as normal at this time of the day, we do believe a number of people on either side of the carriageway may have seen this incident.

“We would like to speak to anyone who saw either the Transit van or the camper van before the incident.

“We’d also like to speak to anyone who witnessed the collision and would ask drivers to check their dash-cam footage.

“If you think you can help with this investigation, please contact Thames Valley Police on the non-emergency number 101, or make a report online, quoting the reference 326 (26/3).”
