Secret Intelligence Service MI6

The Secret Intelligence Service (SIS), often known as MI6, collects Britain's foreign intelligence. The Service is based at Vauxhall Cross in London. Its Chief is Sir John Sawers. SIS provides Her Majesty's Government with a global covert capability to promote and defend the national security and economic well-being of the United Kingdom.

SIS and the media

Enquiries from the media are conducted through a dedicated FCO press officer in FCO Press Office. Because of the secret nature of our work, it's been the policy of SIS and successive Governments not to comment on operations, staff, agents, or relations with foreign intelligence services. SIS does not have a Press Office.
