The Profumo Affair was a political scandal in the early 1960s in the United Kingdom. It involved John Profumo, the Secretary of State for War, who had a brief affair with Christine Keeler, a young model. The scandal escalated when it was revealed that Keeler was also involved with a Soviet diplomat, raising concerns about national security. The affair came to light in 1963, leading to Profumo's resignation and a significant loss of public trust in the government. The scandal highlighted issues of morality and accountability in politics, ultimately contributing to the decline of the Conservative Party in the following years.
