A former PUS, Sir William Strang, described the role as being "the Secretary of State's principal adviser on policy and … his principal agent for administration".[1] And the UK government website, in reference to one of the former Permanent Under-Secretaries, Sir Simon Fraser, agrees calling him "the senior policy advisor to the Foreign Secretary".[2] Additionally, the PUS is the Head of the British Diplomatic Service. Furthermore, the office holder chairs the Royal Visits Committee which provides advice to the Prime Minister on whether to invite Heads of State.[3]
This article contains a list of all permanent under-secretaries in the British Foreign, Commonwealth and Development Office (and its predecessors) since 1790.
As of April 2026, the role is vacant after the dismissal of Sir Oliver Robbins by Prime Minister Sir Keir Starmer over the appointment of Peter Mandelson to the position of British Ambassador to the United States.[4][5]
