Is this the reason for Davis’ resignation?

A Tory source has just explained to me what Davis is up to. He wants to stand down, force a by-election, then run a campaign on 42 days and declare that ‘the people have spoken’. Why? Well, one reason being put about is that he wants leverage in the internal debate over whether or not the Tories should commit to repeal 42 days.

This is high-risk stuff.  Then again, Davis is not averse to risk – as the Alan Clarke diaries show.
