asked Her Majesty's Government:Whether the US Federal Bureau of Investigation has offices in the United Kingdom, and, if so, what are the rules under which it operates and what are its relations with British police authorities.

The United States' Federal Bureau of Investigation has no offices in the United Kingdom. The bureau is represented here by legal attaches in the United States Embassy.All law enforcement offices representing foreign governments working in the United Kingdom must observe guidance issued by the Foreign and Commonwealth Office. A copy of the guidance, known as the "Whitehall Guidelines", is in the Library.The Police Service and the National Criminal Intelligence Service have an excellent relationship with the legal attaches.
