§ 48. Mr. Hector Hughesasked the Paymaster-General, as representing the Lord President of the Council, if he is aware of the ineffectiveness of the security measures at Calder Hall, Cumberland, which was demonstrated publicly and without damage last week by students of Manchester College of Science and Technology; and what action he proposes to take to achieve the necessary tightening up of security measures at all atomic, nuclear and other establishments involving national security.
§ Mr. MaudlingAs a result of the students' operation the general security system at Calder Hall has been reviewed and certain adjustments made. It should, however, be stressed that entrance was gained to a constructional site where54W there was no secret information or material. The perimeter fence which was forced is primarily intended for demarcation. Security measures on an operational site are much more stringent.
