Shirley Ison, the area manager of Premier Travel killed when her car hit a tree near Newmarket, had worked for the company for 36 years.

The 52 year-old mother of two from Chatteris was returning from a week’s holiday in Tenerife when her car crashed into the road between Dalham and Gazeley last Thursday.

Police were called at about 6.10pm and Mrs Ison, 52, received treatment from the ambulance service but was pronounced dead at the scene.

Anyone who witnessed the collision, or who has any information that could help police with their investigation, should call PC Karl Hale of the serious collision investigation team on 101, quoting reference 348 of November 27.

Mrs Ison had been travelling back from the airport in her new BMW 1 series car when the collision happened.

Her career had been entirely spent with the independent travel operator, and was a well respected and liked figure in the community. Premier’s managing director Susan Papworth described her as a “much valued member of the Premier family and will be missed by us all”.

She leaves two daughters, Jessamine and Bethany.
