The British intelligence agency, primarily known as MI6 or the Secret Intelligence Service (SIS), is responsible for gathering foreign intelligence to support the United Kingdom's national security. Established in 1909, it operates under the authority of the UK government and works closely with other intelligence agencies, including GCHQ and MI5. MI6 focuses on espionage and covert operations, collecting information on potential threats from abroad. Its activities are crucial for informing government decisions and protecting the interests of the UK, especially in areas such as counter-terrorism, cyber security, and international relations.
