Highlights of Security Service files released at The National Archives

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. We apologise for the poor sound quality during the first few minutes of the recording.
