Operating in secret
MI6 is one of the most famous and widely portrayed intelligence organisations in the world, but our existence was not publicly confirmed until 1994. Even now most of what we do and the identity of those who work for us remains a secret.
Our work
We are tasked by the government. We recruit agents to spy for us – this means asking people to work with us who have access to information we need to keep the UK safe. We ask them to share that information with us. We protect agents' identities. We analyse and verify the information we receive and supply this in the form of intelligence reports for government.

Intelligence Services Act
In 1994, the Intelligence Services Act formally defined our functions and responsibilities. Our function was defined as “To obtain and provide information about the actions or intentions of people outside the UK.” At the same time, the limits on when we could do this were defined as:
- In the interests of national security;
- In the interests of the economic well-being of the United Kingdom; or
- In support of the prevention or detection of serious crime.
