For the number of temporary staff working in the Department, I refer the hon. Member to the answer given to the hon. Member for North Cornwall (Dan Rogerson) on 22 April 2008, Official Report, columns 1957-8W, by the Parliamentary Secretary, Cabinet Office, my hon. Friend the Member for Corby (Phil Hope).
The Department does not centrally hold information on length of tenure for temporary staff, and the information could be collected only at disproportionate cost.
