Traffic chaos has struck the M25 during the evening rush hour after a huge multi-vehicle crash and delays of more than an hour. Vehicles have been stopped on the UK's busiest motorway in Surrey, anti-clockwise between junction 9 (Leatherhead) and junction 8 (Reigate).

Drivers approaching the accident have been warned to expect delays of up to an hour beyond normal travel times and to allow extra time for their journey. National Highways said in a statement: "There are delays of 90 minutes above normal travel times on the M25 in Surrey anti-clockwise between J10 (for the A3, Guildford) and J8 (Reigate) following a road traffic collision involving 2 vehicles which occurred shortly before 3:30pm."
