Final answer:
The question pertains to a vote regarding Hugh Gaitskell's stance on nuclear disarmament at a Labour Party conference. Without specific historical context, the figures provided cannot be precisely matched to an event. Gaitskell, as Labour leader, grappled with policy issues such as nuclear disarmament during his tenure.
Step-by-step explanation:
At the Blackpool Party Conference, Hugh Gaitskell's official Labour stance on nuclear disarmament was endorsed by a significant margin. The specific numbers in the question seem to refer to the votes by the trade unions and party members on a particular policy issue. However, to provide an accurate answer, we need a precise historical context and the exact figures that are being referred to.
For historical accuracy and understanding, it's important to know that Hugh Gaitskell was the leader of the Labour Party from 1955 until his death in 1963, and he faced several challenges during party conferences, including issues around policies such as nuclear disarmament. If we are discussing the 1960 conference, for example, Gaitskell fought to reverse the party's decision to unilaterally abandon nuclear weapons.
If the question is about the magnitude of votes supporting Gaitskell's stance at a conference, none of the specified numerical options match known historical records precisely without additional context. The importance of such conferences and debates within the Labour Party reflect on the internal democracy and struggles over key policy decisions.
