A serious crash is causing delays on the M25.

All traffic has been stopped anti-clockwise between junctions 10 and 11. Emergency services are working at the scene.

Delays are building quickly on the approach. Drivers are advised to approach with care, allowing extra time for their journeys.

This is unfortunately the second crash of the day. Earlier, a lane near J8 was blocked due to a crash between a car and a HGV.
