British Intelligence Service

The British Intelligence Service, primarily represented by MI5 and MI6, is responsible for national security and foreign espionage. MI5 focuses on internal security, counterterrorism, and protecting UK interests within the country, while MI6 (or SIS) conducts overseas intelligence operations to gather information on foreign governments, organizations, and threats. Their work involves gathering, analyzing, and acting on secret information to prevent crimes like terrorism, espionage, and cyber-attacks. These agencies operate discreetly, coordinating with allies worldwide to safeguard national stability and security.
