HC Deb 24 June 1968 vol 767 cc25-6W
Mrs. Renée Short

asked the Secretary of State for Defence if the open days to be arranged for Members of Parliament to visit the Porton Research Establishment will be comprehensive and include all the classified sections.

Mr. John Morris

The Open Days will be as comprehensive as possible, though as I explained to my hon. Friend the Member for West Lothian (Mr. Dalyell) on 12th June, I have to balance national security and public interest. Although that means that it will not be possible to disclose information which is classi-field, this represents only a small proportion of the work of the establishment and I am sure that the Open Days will be well worth while.—[Vol. 766, c. 205.]
