(Author's note - I am not 'The Devil's Kitchen')
Without wishing to hog my host's blog, and while still adhering to the belief that the reasons David Davis has stated for his resignation make it an unqualified good, a thought occurred to me last night which I have not seen reflected in any of the official commentary on the event that I have read thus far, and which might be worth sharing.
Mr. Davis's resignation is not, as Iain Martin has described it, 'political lunacy'. Although it might appear to some to be quirky, if not quixotic, it most certainly would appear to be principled; and yet, from a particular point of view, it might seem to have been guided by a cold, steely calculation.
If - make that when - Mr. Davis is re-elected, as an individual he will possess the authority which comes from having made a stand on a point of principle. Already a big beast, he will re-enter the House of Commons an even bigger one. Mr. Davis is always going to be a candidate for the leadership of the Conservative Party, and he knows it. His re-election on a point of principle might either make him David Cameron's natural successor - or else give him the impetus necessary to mount a leadership challenge.
Mr. Davis is an ambitious man, otherwise he would not have reached the level he has already achieved. It would be interesting to know precisely what ambitions he still nurtures - if they include the leadership of his party, it might be the case that his resignation will do those ambitions no harm. He's certainly given David Cameron a hell of a job to do.
