FORMER MODEL CHRISTINE Keeler has passed away aged 75.

She became famous for an affair she had with Tory cabinet minister John Profumo which forced him to resign in 1963.

Keeler’s son Seymour Plait confirmed to The Guardian that his mother died at the Princess Royal university hospital in Farnborough last night.

Stephen Ward, an osteopath, introduced society girl Keeler to Profumo in 1961, sparking an affair between the pair.

However, Keeler was rumoured to be having an affair with a Soviet diplomat at the same time, raising fears of an intelligence leak as it was the height of the cold war.

Profumo initially denied the affair in the House of Commons saying there was no “impropriety” in their relationship.

He later admitted lying to the house and resigned.

A BBC series about the scandal is due to start filming next year.
