Severe delays are expected as police clear an eight-vehicle pile-up at the Dartford crossing.

Rush hour traffic queues are building up due to the rolling road block after the crash on the M25 anticlockwise at J1B for the A282 and Dartford.

Congestion is already building up back to J2 of the M25, the Darenth Interchange.

Police say they are clearing the scene, but drivers should expect severe delays.
