Description
The Secret Intelligence Service (SIS), commonly known as MI6, is the foreign intelligence service of the United Kingdom, tasked mainly with the covert overseas collection and analysis of human intelligence (HUMINT) in support of the UK's national security. SIS is a member of the country's intelligence community and its Chief is directly accountable to the Secretary of State for Foreign and Commonwealth Affairs. Formed in 1909 as a section of the Secret Service Bureau specialising in foreign intelligence, the section experienced dramatic growth during World War I and officially adopted its current name around 1920. The name "MI6" (meaning Military Intelligence, Section 6) originated as a flag of convenience during World War II, when SIS was known by many names. It is still commonly used today. The existence of SIS was not officially acknowledged until 1994. That year the Intelligence Services Act 1994 (ISA) was introduced to Parliament.
