A MAN who died in a single-car crash on the M40 this morning was the 61-year-old driver who had a 'medical emergency' at the wheel, police have confirmed.

The man, who has not yet been named, crashed his silver Vauxhall Vectra into a bridge support at Junction 9 near Bicester just before 8am after suffering what paramedics called a 'medical emergency' at the wheel. 

He was pronounced dead at the scene and police said his next-of-kin have been informed.

Sgt Mark Ponting from roads policing said: "We are appealing for witnesses to this fatal collision, which occurred during extremely wet weather and which sadly resulted in a man losing his life.

"I would like to speak to anyone who saw what happened or who saw the vehicle travelling prior to the collision, who has not already spoken to police."

The northbound M40 carriageway, on which the accident happened, was originally closed between junctions 8a and 9, causing six-mile long queues on the approach.

Traffic has now cleared and all lanes re-opened at around 6pm.

South Central Ambulance Service said it sent a rapid response vehicle, a paramedic team leader, an ambulance and an enhanced care response unit to the scene, but that the driver of the vehicle was not taken to hospital.

The service did not say what type of medical emergency the driver had suffered.
