Permanent secretary

A permanent 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. The role originated in the civil service of the United Kingdom and has been adopted in several Commonwealth countries as well as other countries influenced by the Westminster system.
