He is a Sinn Fein-loving, monarchy-baiting, Israel-bashing believer in unilateral nuclear disarmament. It is nonsense to compare him to Michael Foot, who had been at least a Cabinet minister and before that a distinguished campaigner against the pre-war appeasers. This is a man who, for more than 30 years, has made a political career out of being explicitly and avowedly on the Spartist Left. He is a frondist, an inhabitant of the semi-Trot margin, an unrepentant lover of oppositionalism. Never in all his wildest dreams did he imagine that he might be leader of what has been – until this year – one of the major parties of government; and now he is having greatness thrust upon him.
