FWIW this 'we' thinks there
are important constitutional arguments for having a general election within a reasonably short time of a new Prime Minister taking over. This business of being able to change horses in mid-stream without the electorate being invited to have a say seems pretty dubious to me on constitutional grounds alone.
But then I'm not that wild about the convention of Prime Ministers being able to choose their own moment to make a bolt for it anyway and think there are strong arguments for moving to fixed term administrations - so that makes me at least twice removed from current reality.
