A woman who was killed in a motorway pile-up, which also left a man and a baby injured, was last night named as 25-year-old Diana Lesley Cross.

The three vehicle crash, which brings the death toll on Oxfordshire's roads to 57 this year, closed the M40 for five hours on Saturday.

The pile-up means the number of road deaths in the county is now 17 higher than last year's total.

Traffic was thrown into chaos after the accident, which happened on the southbound M40 just after 7am, about a mile before junction nine at Bicester.

Police said Ms Cross's white Vauxhall Astra crashed into a green Ford Escort van which had hit the central reservation. A red Rover then ploughed into the Astra.

Ms Cross was pronounced dead at the scene, while a one-year-old baby girl and a man, who were in the same car, were taken to Oxford's John Radcliffe Hospital with minor injuries.

The Oxford coroner has not revealed where Ms Cross was from.

The drivers of the other two vehicles were not believed to be seriously injured.
