A serious accident has closed the A38 in the Glynn Valley between Dobwalls and the A30.

Police say the road is expected to be closed for some time.

Diversions have been put in place, but holiday traffic was already being reported as heavy across Devon and Cornwall and queues are being reported in the area.

There is no detail of the accident nor of any injuries. Police, ambulance and fire service personnel are all at the scene.
