Each Minister responsible for a Department has the authority to designate a post as reserved if it meets one of the categories set out in the European Communities (Employment in the Civil Service) Order 2007. If a post does not fall within these categories, then it is not capable of being reserved. The Cabinet Office will be collecting information in due course on the number of posts designated by Ministers as reserved.
It is estimated that about 5 per cent. (27,000) of Civil Service posts will need to be reserved to UK nationals.
Figures for 2006-07 are still to be finalised. For information on earlier years, I refer the hon. Member to the answer given to him on 27 June 2006, Official Report, column 314W.
