ALL lanes of the M5 northbound have reopened following a serious crash earlier today.

Police, fire, ambulance crews and an air ambulance were called to a four-vehicle collision between J24 and J25 just after 2.30pm.

Northbound, the motorway is gridlocked, and there's lots of traffic on the southbound side too as the air ambulance had to land there.
