Motorists are facing long delays on the M25 with congestion back to the QE2 Bridge following an earlier crash.

All lanes have since reopened after a full hold lasting more than 30 minutes on the M25 clockwise, but traffic congestion is still heavy.

Drivers are experiencing severe delays on the Dartford Crossing's southbound route between the A282 and M25, with travel speeds reduced to an average of just 15 mph.

Congestion is expected to persist as traffic continues to recover from the earlier incident.

Details of the crash are yet to be revealed, but unconfirmed reports state it involves a motorcyclist.
