have heard some speculation that that twat johnson will jump ship to the middle earth mid bedfordshire constituency at the by-election when nadine dorries goes to the lords, on account of not having a great majority in uxbridge, and most of the the tory 'levelling up' policy being to punish london for voting for the wrong colour (i mean rosette of course) mayor.
although not sure how this works for a sitting MP part way through a parliament, though - fairly sure it's happened before during a general election...
