TRAFFIC is moving slowly on parts of the M5 this morning (Sat) following an accident.

Police and ambulance crews are on the scene at the crash near the Portishead junction northbound.

A van was involved in the collision and one lane of the motorway has been closed between junctions 19 and 20.

A vehicle also appears to have left the motorway over the embankment.

The problem is having a knock-on effect for the rest of the area, down to Weston.
