Cabinet Office Permanent Secretary
The Permanent Under-Secretary of State for the Cabinet Office, known informally as the Cabinet Office Permanent Secretary, is the second-most senior civil servant of the Cabinet Office. It was conventionally joined with the positions of Cabinet Secretary and Head of the Home Civil Service. This triple role was disbanded in January 2012 after Gus O'Donnell retired. Due to the Cabinet Office having expanded and taken on new responsibilities since the 2010 election, including cutting costs and driving efficiency across government, it is led by a dedicated Permanent Secretary. The current Permanent Secretary of the Cabinet Office is Alex Chisholm. List of permanent secretaries
