64. Mr. Riggs-Davisonasked the Prime Minister what agreements have been made with the United States Government 142W or Atomic Energy Commission to restrict or delay the publication in the United Kingdom of information about Zeta or other British achievements in the development of nuclear energy for peaceful purposes.
§ Mr. R. A. ButlerI have been asked to reply.
None, save those relating to information not divulged on security grounds.
The release of information is governed by rules of security classification, which are reviewed periodically. Following the latest review the Atomic Energy Authority and the United States Atomic Energy Commission arranged for simultaneous publication of information about the results obtained in research establishments in both countries as soon as all the papers could be made ready.
