ABSTRACT
Western proposals for a CTBT formally rested with the Joint UK and US Memorandum tabled in the ENDC on 1 April 1963. This stated that, subject to certain conditions relating to the conduct of inspections, an annual quota of seven on-site inspections could be accepted on the territory of each nuclear weapons state in order to provide some deterrent against clandestine cheating. MOD's view at the end of 1968 was that there was in fact little prospect of a test ban until such times as there was progress in strategic arms limitation between the superpowers. At the end of 1969 the UK's formal position was that a CTBT was still a major aim of HMG's policy, but it was recognised that in practice the effective conclusion of such a treaty depended on progress by both the USSR and the US towards a Strategic Arms Limitation agreement (SALT).
