This is the 26th Security Service records release containing 180 files, bringing the total number of Security Service records at The National Archives to more than 4,725.

As with previous releases, around three quarters of the records are personal files relating to individuals (KV 2), with the remainder a combination of subject files (KV 3), policy files (KV 4), organisation files (KV 5) and list files (KV 6). The records cover a range of subjects and span the inter-war, Second World War and post-war eras.

Personal files are listed under the following categories:

  • German intelligence agents and suspected agents (KV2/3386 - 3421)
  • German intelligence officers (KV2/3422 - 3426)
  • Subject of Security Service enquiry (KV2/3427 - 3438)
  • Soviet intelligence officers (KV2/3439 - 3488)
  • Soviet intelligence agents and suspected agents (KV2/3489 - 3492) 
  • Right-wing extremists (KV2/3493 - 3495)
  • Communists and suspected communists, including Russians, and communist sympathisers (KV2/3496 - 3530)

Subject files (KV3/403-417)
Policy files (KV4/448-464)

Organisation files (KV5/132)

List files (KV 6 104-105)

Some 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.

Highlights include:

  • Captured French Abwehr agent, Oliver Marie Joseph Mordrelle, revealed under interrogation secret Nazi plans to create post-war 'world disorder' from which they hoped a Fourth Reich would emerge (KV2/3410)
  • Plans to assassinate the Foreign Secretary, Ernest Bevin, and other leading British political figures including Winston Churchill by Jewish terrorist groups opposed to the British presence in Palestine (KV2/3428)
  • A botched 1942 Abwehr operation, codename PASTORIUS, to land German saboteurs in the USA in U-boats ended in farce when their submarine ran aground and one saboteur publically declared himself to be a secret agent whilst under the influence of alcohol (KV3/413)
  • German plans to use poisons, booby traps and bacterial warfare against the Allies after the end of the war - including poisoned Nescafe, alcohol, chocolate and aspirin (KV3/414)
