At the height of the Cold War, only a year after the Cuban Missile Crisis, the gorgeous teenage model had simultaneous affairs with a Russian diplomat and Britain’s secretary of state for war, John Profumo.
Profumo, a senior figure in Harold Macmillan’s Tory government, was married and, of course, privy to all the country’s military secrets.
What sealed Profumo’s fate was false denial of the affair in a speech to the House of Commons.
Sexual hanky-panky with a mistress, tut-tut.
Sharing the mistress with the country’s greatest enemy when you know state secrets and could be blackmailed, well, a bit of a problem.
Lying to fellow MPs, goodbye.
