If you have information that you think will be of interest to us.
Read our important advice before you make contact.
Because of the secret nature of our work, SIS do not have a Press Office. And it’s our practice to never comment on operations, staff, agents, or relations with foreign intelligence services.
All media enquiries should be made through the FCO Press Office where we have a dedicated FCO Press Officer.
