John Dennis Profumo, CBE (30 January 1915 - 9 March 2006) was a British politician, serving as an MP beginning in 1940. He is best remembered for his affair with Christine Keeler while he served as Secretary of State for War in the Conservative government of PMHarold Macmillan. The affair lasted from 1961 until 1963, when the affair came to light. While the philandering was bad enough, it was made worse by the fact that Keeler was also involved in a relationship with the senior naval attaché at the Soviet Embassy, adding national security concerns. While the Conservatives had been in a period of declining popularity, the Profumo Affair didn't help. Profumo himself resigned in 1963. He spent the remainder of his life engaged in charity work.
