I have been asked to reply.
Since 2003, the Government have published on an annual basis the names and overall cost of special advisers and the number in each payband. For information relating to the last financial year I refer the hon. Member to the written ministerial statement made by my right hon. Friend, the Prime Minister, on 21 July 2005, Official Report, columns 158-61WS. Information on special advisers for this financial year is currently being collected and will be published in the normal way when available.
This information prior to 2003 is not available in the form requested and could be provided only at disproportionate cost.
All official travel by special advisers is undertaken in accordance with the requirements of the Ministerial Code and the Civil Service Management Code.
