A lane has been closed on the M4 Westbound between junctions five and six as a result of a crash between the two junctions.

Traffic has built up with one lane currently closed because of the earlier crash on the road.

Congestion is also affecting the London-bound carriageway as passers by slow to look at the crash.

There has also been an accident on the M4 Westbound after junction 8/9 A404(M). Two lanes have been closed as a result.

Both incidents have now been cleared.
