Since 2003, the Government have published on an annual basis the names and numbers of special advisers in each pay band. For the most recent information I refer the hon. Member to the statement made by my right hon. Friend the Prime Minister on 22 November 2007, Official Report, columns 147-50WS.
Information on the employment of special advisers prior to 2003 was provided at regular intervals and is available in the Library of the House.
