Have to say I'm 1000% with Boris on this. The audacity of the MPs to continue this delay and a complete disregard for their constituents' will. And I'm not a Tory. I hope he does not have to negotiate a delay. Get a no deal and go.
An MP should be looking after the best interests of their entire constituency - Leavers, Remainers, Labour, Tories, BXP, LD, non-voters, everyone. They do this by exercising their judgement, not by turning up as a glorified proxy vote for some nebulous combined 'will' of thousands of different people.
How many constituencies are there in the UK where the Leave vote was an outright majority of the regional population (not just those that voted)? Just because 14 or 15 years old can't vote (for example) doesn't mean an MP shouldn't factor them into their decisions.
