HC Deb 08 April 1968 vol 762 cc188-9W
Sir Ian Orr-Ewing

asked the Secretary of State for Defence to what extent during 1967 fighter command aircraft intercepted Russian reconnaissance aircraft over the North Sea.

Mr. Merlyn Rees

Over the past year there has been a reduction in the number of Soviet flights over the North Sea. It would not be right for me to disclose further details.
