Masterman Report

The Masterman Report, published in 1950, was a comprehensive review of the British government's security and intelligence services following World War II. Led by Lord Lionel Masterman, the report examined how effectively these agencies, like MI5 and MI6, protected national security. It recommended improvements in organization, coordination, and oversight to strengthen counter-espionage efforts and prevent infiltration by enemies. The report aimed to modernize intelligence operations during the Cold War era, ensuring better protection for the UK against espionage, sabotage, and other security threats.
