This is the twenty-fourth Security Service records release and contains 196 files, bringing the total number of its records in the public domain to more than 4,300.

As with previous releases, around 80% of the records are personal files relating to individuals (KV 2), with a small number of subject files (KV 3), policy files (KV 4), organisation files (KV 5) and list files (KV 6).

The files cover subjects from the pre-war period, the Second World War and the post-war period, dealing with a range of groups and subjects.

Personal files are listed under the following categories:

  • German intelligence agents and suspected agents (KV 2/3114-3132)
  • Other espionage cases (KV 2/3133-3156)
  • German intelligence officers (KV 2/3157-3163)
  • Subjects of Security Service enquiries (KV 2/3164-3181 and KV 2/2261-2264)
  • Soviet intelligence agents and suspected agents (KV 2/3182-3186)
  • Right-wing extremists (KV 2/3187-3196)
  • Communists and suspected communists, including Russian, and Communist sympathisers (KV 2/3197-3264)

Subject files (KV 3/372-382) in this release include files on Communist activities among musicians and actors (KV 3/375-380), Communism in the UK during 1925-1933 (KV 3/382) and Japanese espionage in India (KV 3/373).

Policy files (KV 4/443-445) in this release cover subjects including the history of the MI5 surveillance unit (KV 4/443) and policy on the interception of private telephone lines (KV 4/445).

Organisation files (KV 5/84-107) in this release include files detailing investigation into the activities of the Hitler Youth in the UK in the years leading up to the Second World War (KV 5/84-89).

There are also three List files (KV 6/101-103) concerning Hungarian-born Edward de Grunchy, who escaped from a German prisoner of war camp in 1941 and arrived in Britain with a suspicious story which lead to his detention on security grounds.

A few files have been weeded while others have been reconstituted from microfilm of the original document and are therefore in photocopy form.

Most personal files include a minute sheet attached to the inside cover, providing a useful index to the file.

For the purposes of this press event we have highlighted a selection of the key files, focusing on personal, policy and organisation files.
