To ask the Secretary of State for Defence what consideration was given to the security implications of releasing transcripts of the Farm Hall tapes of conversations of German atomic scientists in the second world war recorded under Operation Epsilon, prior to their release.

The documents were originally "retained by Department" under section 3(4) of the Public Records Acts 1958 and 1967 on the grounds of national security. They were reviewed in 1992, and it was judged all sensitivity had lapsed and that they could be released into the public domain.
