MI5
UK security service
MI5 is the United Kingdom's domestic intelligence and security agency, responsible for protecting the country against threats such as terrorism, espionage, and sabotage.
The name derives from "Military Intelligence, Section 5," reflecting its origins during World War I, though it is now officially called the Security Service.
MI5 operates within British borders, distinguishing it from MI6, which handles foreign intelligence.
The spy thriller featured an MI5 agent tracking down a mole in the government.
