UPDATE: Traffic has now returned to normal. 

The M25 clockwise is blocked following a crash involving a motorbike and car near Iver this morning.

Drivers have been warned to expect delays near junction 16 - M40 - and junction 17 A412 - Maple Cross - as emergency services have blocked the road while they “deal with the incident”.

Traffic is allowed to pass on the hard shoulder.

Motorists are being diverted via the M40 to junction 1 - Denham Roundabout - then north along the A40 to A412, heading north to rejoin the M25 at junction 17.
