Mandy Rice-Davies, one of the women at the centre of the Profumo affair which threatened to bring down Harold Macmillan's government in the 1960s, has died of cancer age 70.

The former model lived with Christine Keeler, whose affair with war minister John Prufomo led to his resignation in 1963. Keeler was also said to be having a relationship with Yevgeny Ivanov, a Soviet naval attaché at the Soviet Embassy in London in the early 60s.

Rice-Davies became notorious for claiming to have had an affair with Lord Astor, a British businessman and Conservative party politician. When told he had denied it, she famously said from the witness stand: "Well he would, wouldn't he?"
