Mr. Winnick

To ask the Prime Minister, pursuant to his answer of 5 February,Official Report, column 609, concerning travel costs, for what reasons comparable data for 1983 to 1987 are not available; and if he will make a statement. [15169]

The Prime Minister

Comparable data for 1983 to 1987 are not available because it is departmental policy, which accords with the guidance in "Government Accounting" and the requirements of the National Audit Office, to destroy financial records after five years.
