Long queues are forming on the Dartford Crossing approach due to a crash on the M25.

Two lanes are closed anti-clockwise and traffic is stretching all the way back towards Junction three for the Swanley Interchange.

It's due to a crash involving three vehicles which happened just after 11.15am between that junction and junction 2 for the Darenth Interchange, which connects to the A2.

National Highways says two out of four lanes are closed creating delays of up to 20 minutes owing to a road traffic collision.

Emergency services are in attendance while the incident is dealt with.

Police say no life-threatening injuries are believed to have been reported.
