I've just finished watching Andrew Marr's interview with David Cameron. It was curiously uninteresting. Marr interrupted Cameron's answers every ten seconds which led to it being rather disjointed. He didn't really lay a glove on Cameron, but on the other hand Cameron wasn't sparking on all cylinders either.
The only moment of 'squrim' came when Cameron was asked how much his personal wealth was. Marr clearly viewed this as Cameron's 'pill popping' question. I thought the best answer would have been "I'm worth a good bit less than you, Andrew".
Cameron was calm and strong on Europe, reasoned in his explanation of the new welfare and employment proposals, and made clear that election debates should take place during the election campaign as well as in advance of it.
So all in all a pretty low key and headline free interview. You can probably file it under 'job done'.
