A collection of previously classified documents from MI5 has been released.
These records span a variety of topics, primarily focusing on the organization’s early years before World War I, up to the mid-1970s.
The released files unveil new information regarding the Cambridge spies Kim Philby, Anthony Blunt, and John Cairncross, including their confessions. They also provide insight into related cases, such as Constantin Volkov and Philby’s first wife, Litzi.
Additionally, the collection features historical reports and documents from 1909 to 1959, a wartime “watchers” manual offering surveillance advice for MI5 officers, papers related to investigations into the Communist Party of Great Britain, and exchanges between MI5 and the FBI.
All the available files can be explored, viewed, and downloaded from Discovery, our catalogue, here.
