The official name for the UK's foreign intelligence agency, widely known by its popular designation MI6. Operating under the Foreign, Commonwealth and Development Office, the Secret Intelligence Service collects intelligence abroad to support national security. In popular culture, it's become shorthand for suave spycraft — think James Bond's employer — though the real organization is considerably more bureaucratic and secretive than any Hollywood portrayal.
