§ 18. Mr. Zilliacusasked the Lord Privy Seal why the British plan for controlling tests, without on the spot inspections, through a string of Commonwealth posts in North America, the United Kingdom, Africa, Asia and Australia, was not sub- 496 mitted to the Disarmament Commission at Geneva.
§ Mr. HeathThere is no United Kingdom plan of the kind described. What we have proposed is a world-wide network of control posts, as set out in the United Kingdom-United States draft treaty of April, 1961.
§ Mr. ZilliacusWere not proposals on these lines submitted by Sir Solly Zuckerman and Sir William Penny on a visit to Washington which they were satisfied would detect even minor underground tests? These were then opposed by the United States on the ground that they would not be acceptable to Congress and the whole scheme was then dropped and never put forward at Geneva.
§ Mr. HeathNo, Sir. I cannot give any indication of the views expressed between scientists during their conversations in Washington.
