HC Deb 07 February 1968 vol 758 c181W
Mr. Emery

asked the Secretary of State for Foreign Affairs what percentage of his Department's office records and files date back over three years, five years and seven years.

Mr. Mulley:

Approximately 15 per cent., 23 per cent. and 30 per cent. I regret that precise information is not readily available and could not be obtained without incurring considerable expense.
