The Profumo affair was a political scandal that took place in London in 1961. It centered around John Profumo, the Secretary of State for War under Prime Minister Harold Macmillan, who engaged in an extra-marital sexual relationship with Christine Keeler, a 19-year-old would-be model. At the time, Profumo was married to actress Valerie Dobson, one of Britain's best-known actresses. Although Profumo initially denied the liaison, he was soon forced to admit to it, leading to his resignation from government and Parliament. The affair de-stabilized the Macmillan government, eventually leading to the Prime Minister's resignation.
