The Security Commission, sometimes known as the Standing Security Commission,Geoffrey Philip Wilson, "Cases and materials on constitutional and administrative law", Cambridge University Press, 1976 p. 98. was a UK non-departmental public body or quango established in 1964 to investigate breaches of security in the public sector. It was abolished in 2010, on the basis that government would investigate breaches of security as and when they occurred.

Origins The idea of the Security Commission, initially canvassed by the Prime Minister Harold Macmillan, was first publicly suggested by his successor Sir Alec Douglas-Home in a Parliamentary debate about the Denning Report into the Profumo affair on 16 December 1963. Douglas-Home envisaged that the commission would consist of retired civil servants and would be chaired by someone from the judiciary. It was to investigate matters referred to it by the Prime Minister of the day and issue its reports back to the Prime Minister, with the Leader of the Opposition consulted before any inquiry and after the report was completed. Douglas-Home met with the Leader of the Opposition Harold Wilson (who had given a cautious welcome to the proposal) on 22 January to agree the details.

Formation On 23 January 1964 the formation of the Security Commission was announced, with the terms of reference:

Harold Wilson expanded the remit on 10 May 1965 to allow the Commission to investigate circumstances where a breach of security might have occurred.

Reports The Security Commission issued fifteen reports during its existence.
