HC Deb 20 June 1967 vol 748 cc246-7W
Q14. Mr. Hooson

asked the Prime Minister in what circumstances a person not cleared by positive vetting is allowed to remain in a post concerned with national security.

The Prime Minister

An officer who has not been cleared by positive vetting is never allowed to remain in a post for which positive vetting is required—that is, a post which involves regular and constant access to the most highly classified information.
