Two lorries have reportedly crashed on a major motorway in south Essex with drivers facing long delays as parts of the road have been closed.

Two lanes are closed on the M25 junction 30 clockwise exit after a crash involving two lorries. As a result there is only access to the A13 eastbound.

There is also a partial closure of the junction 30 roundabout.

The crash is blocking the roundabout on the M25 at junction 30, Essex County Council's traffic control reports.

There are long queues on the M25 clockwise from J28 (A12) and on the A13 both ways approaching the M25 at J30.

Drivers are facing a 50-minute delay on approach with four miles of congestion.
