A man has been cut free from his car and taken to hospital following a serious crash this afternoon.
Firefighters were called at just after 1pm to a two-car crash on the M25 anticlockwise.
It happened between junctions one and three, the Swanley interchange and the Darenth turn off.
Ambulance crews took the man, believed to be in his 40s, to the Princess Royal Hospital in Farnborough.
