Police have reopened the M5 after a "horrific" crash on the motorway killed four people over the weekend.

A woman and two children remain in hospital with life-threatening injuriesafter a lorry collided with oncoming traffic between junctions 16 and 14.

The motorway was closed for the whole of Sunday while investigations were carried out, and one northbound lane still remains closed.

Police say the work has been "painstaking".

Emergency service personnel have been working tirelessly at the scene in harrowing conditions and I'd like to praise them for the work they've done and are still doing.

Superintendent Simon Ellis

The lorry driver was taken to hospital to be treated for minor injuries and has been interviewed under caution.
