An accident on the M40 caused rush-hour traffic chaos this morning.

One lane was closed going southbound between J4 (Handy Cross) and J3 (Loudwater) until around 8.20am, as emergency services worked to clear the scene.

All traffic was also held until around 7.35am.

Drivers were being warned of long delays, of around an hour, on approach.

The crash also caused traffic mayhem around High Wycombe, with drivers reporting travel times of more than an hour travelling across the town, and long queues at Handy Cross roundabout.
