Permanent secretary

A permanent secretary (also known as a principal secretary) is the most senior civil servant of a department or ministry charged with running the department or ministry's day-to-day activities. Permanent secretaries are the non-political civil service chief executives of government departments or ministries, who generally hold their position for a number of years (thus "permanent") at a ministry as distinct from the changing political secretaries of state to whom they report and provide advice. rdf:langString
