The M25 is closed following a serious crash.

It happened just after 11.15pm last night and the motorway is closed anti-clockwise between J28 for A12 and J27 for M11.

Officers are on scene continuing to carry out investigations.

The road will be closed well into the morning and there are long delays now on the approach to J28.

There is a diversion in place; motorists approaching the closure at junction 28 may exit the M25 and join the A12 into London, then at the junction with A406 the North Circular join the A406 north towards the M11, then join the M11 northbound, to re-join the M25 at junction 27 and follow the diversion signs.

The diversion route is approximately 19 miles long and will add to the overall delays.

Drivers planning to travel through this area are strongly encouraged to seek alternative routes and to allow plenty of extra time for your journey.
