HC Deb 07 February 1968 vol 758 c184W
Mr. Emery

asked the Postmaster-General what percentage of his Department's office records and files date back over three years, five years and seven years.

Mr. Edward Short:

Statistics are not available in the form required by the hon. Member. No record is retained for longer than is necessary for administrative or historical reasons. The great majority of files and records are therefore destroyed after three years.
