Mr Profumo was forced to resign from the Cabinet in 1963 for lying to the House of Commons over his affair with call girl Christine Keeler.
In the scandal, which happened at the height of the Cold War, it emerged that Christine Keeler had also been involved with Commander Yevgeny Ivanov, a Soviet intelligence officer and assistant naval attache in London.)
