Mandy Rice-Davies, a former model who was at the centre of one of Britain's biggest political sex scandals - the 1960s Profumo Affair - has died aged 70 after a short battle with cancer, her publicist said on Friday. Rice-Davies lived with Christine Keeler, who had simultaneous affairs with Britain's then Minister of War John Profumo and a Soviet naval attach?, a potential Cold War security breach which rocked the then Conservative government of Harold Macmillan. The 1963 scandal, which led to Profumo's resignation and disgrace, attracted widespread public interest as lurid details of the m?nage ? trois emerged.
