Ever been at a football match where the crowd starts to file out just before the full time whistle? You get the picture.
He's right, so I won't delay you too long. I think David Cameron was wrong to raise the issue of MPs' expenses. It just smacked of politicians talking about themselves. He made some totally valid points on the timetable for the review and 'long grass' , but today was, perhaps, not the time. But he did get an agreement from the Prime Minister to meet him and Nick Clegg. He should hold it sooner rather than later, go into the meeting with proper proposals, which could get cross party support and be non partisan in nature.
Cameron then moved on to the G20, but somehow the exchanges never really caught light. But what we did get was a clear signal from the Prime Minister that his entire line of attack on the Conservatives at the next election will be that they will "cut pensions, cut child benefit and cut the health service." How edifying. I think I am right in saying that David Cameron only used 5 questions, which is quite normal. But with the attack by the PM in answer to his 5th question, I thought David Cameron should have improvised and given a withering retort.
Nick Clegg's questions concerned green jobs. Again, there was a lot of synthetic anger, but not a lot more.
