§ Mr. Frank Allaun
asked the Secretary of State for Foreign Affairs if, in order to give encouragement and an example to 254W the Eighteen-Nation Disarmament Conference at Geneva, he will give an undertaking that Great Britain will end all underground nuclear test explosions forthwith.
§ Mr. George Thomson
As my right hon. Friend the Prime Minister explained to the House on 20th July last, our policy is to internationalise our nuclear deterrent. In so far as it must be kept in being for that purpose, we must take such steps as are necessary to ensure its effectiveness.
