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 Alex Younger. 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.
