Corbyn might win office, but he’ll struggle to win power

The vote of no confidence in Dominic Grieve shows the Tories are, like Labour, vulnerable to bolshiness in their own local associations. In fact, the Conservatives might turn out to be more effective at purging MPs because, for all of the noise, the Corbynites have not done much. And if Jeremy Corbyn ends up in No10 after a snap general election, he may soon wish that he had done more. Two polls in the past 24 hours have been pretty good for Labour. Opinium has them level-pegging with the Tories on 35 per cent while Delta gives them a five-point lead (though this falls to three points when respondents are given the option of Change UK). On these polls, Labour would form the largest party in the Commons – but it would not have a majority. In which case, Corbyn could expected to be hemmed in by his rebels to a far greater extent than Theresa May is being constrained by the ERG.
