 Prime Minister Clement Attlee, who succeeded Churchill in June 1945, created the Gen 75 Committee on 10 August 1945 to examine the feasibility of a nuclear weapons programme.It was known informally by Attlee as the "Atomic Bomb Committee", although no explicit decision to build one was made until January 1947.The Gen 75 Committee differed from other Gen committees in that its deliberations were not reported to the full cabinet, and were shrouded in secrecy even at that level.
