There’s no turning back for David Davies. He has applied for (and presumably been granted) the Stewardship of the Chiltern Hundreds, thus disqualifying himself from membership of the House of Commons. The by-election will be held on 10 July.

I was wrong – he didn’t try to ask a question at PMQs, which begs the question, why did he wait until yesterday to resign and not just do it on Monday?

There’s no doubt DD will be grievously offended by the disdain in which the other parties – particularly Labour – hold him and his by-election. His only chance now of making a serious point is if he can secure a turnout which is significantly higher than the 70.2 per cent achieved in 2005. This will be difficult given the absence of a real contest. And if turnout is significantly lower than that, DD will have shown his gesture to have been not only empty, but very, very expensive.
