The Permanent Under-Secretary's Department (PUSD) was the department responsible for liaison between the Foreign Office and the UK's intelligence agencies, and all of these records are intelligence-related.

In 2005, the Foreign and Commonwealth Office (FCO) transferred into the public domain for the first time records from PUSD, dating from 1873 until the outbreak of the Second World War on 3 September 1939 (see FO 1093/1-107).

This second tranche comprises 463 pieces covering the period from September 1939 to 1951 as well as 17 files from 1903 to 1913.

At the same time as this release, records from the Cabinet Secretary's miscellaneous papers, CAB 301, are being transferred to The National Archives for the first time. The first tranche of papers, covering 1936 to 1951, is concerned almost entirely with the central organisation and funding of British intelligence.

Highlights include:

  • Security matters relating to Wallis Simpson and the Abdication of HM King Edward VIII in 1936 (CAB 301/101)
  • Assassination priorities for D-Day (FO 1093/292)
  • Details of a British scheme to bribe Spain into keeping out of the war (FO 1093/233-234)
  • An account of a drunken wartime meeting between Stalin and Churchill in Moscow (FO1093/247)
  • Intelligence priorities, covert operations and special operations during the early Cold War (FO 1093/447, FO 1093/375 and FO 1093/347)
