The M4 is closed westbound following a serious collision earlier this afternoon.
Emergency crews were called to the motorway between junctions 16 and 17 at around 4pm, following a one-vehicle crash involving a black BMW.
The driver, who collided with the central reservation, was pulled from the wreckage by a passing army medic and truck driver who gave emergency first aid.
Great Western Air Ambulance attended the scene, airlifting the man to hospital – where he sadly died of his injuries.
