Mandy Rice-Davies, a key figure in Britain's biggest Cold War political scandal, the "Profumo Affair," has died. She was 70.

Her PR firm, Hackford Jones, said Friday that Rice-Davies died Thursday evening "after a short battle with cancer."

Rice-Davies was a model and London nightclub dancer when her friend Christine Keeler had an affair with War Secretary John Profumo. The revelation that Keeler had had slept with both Profumo and a Soviet naval attache caused a media sensation and almost toppled the British government in 1963.

At a trial stemming from the scandal Rice-Davies dismissed a denial by aristocratic party host Lord Astor that they'd had an affair with a phrase that became famous: "Well, he would, wouldn't he?"

Rice-Davies later performed in cabarets and married several wealthy men.
