Well, they won the PV 46-40 (1.5 million), with a majority of 5. Keeping in mind that Korea would be a factor, and rationing is still in effect. So in a way, the war never really ended until the Korean armistice. If somehow Lab wins a safe (20+) majority, Churchill retires, and perhaps Eden becomes Leader of the Opposition. Macmillan, Butler & Co. wouldn't be as prominent as OTL without serving as senior ministers in the Churchill II Cabinet. Though both of them are rabidly ambitious, as the '57 coup showed. If Gaitskell gets in, he sounds like a Blair prototype, so there wouldn't be more nationalisations like Wilson did IOTL. Callaghan and Jenkins (leaders of the Lab right) would eventually become prominent in the party.
