I have to be honest and say that this week's PMQs was not David Cameron's finest hour. If I was scoring it for Sky News I would give Brown 4, Cameron 3 and Clegg 4. I can't really understand the logic of Cameron asking about internal House of Commons issues when there are far more important things to talk about. He did raise the question of an the EU Treaty referendum in his fourth question, but it came across almost as an aside. His final point about a TV debate with the PM was well made and made the PM look uncomfortable. Gordon Brown looked at ease throughout the earlier line of questioning and although he did his usual thing of turning the question back on Cameron on two occasions he came across as rather more fluent than usual. He also made quite a funny barb at LibDem Nick Clegg leader saying: It's nice to see the Rt Hon Gentleman back. Perhaps he will stay long enough to hear the answers". Clegg's response was good - especially as it appeared to annoy the Speaker - and his subject of questioning (mental health) was one which gets too little coverage.
UPDATE 6.22pm: The response in the comments have been interesting, and reflects what Iain Martin has said on Three Line Whip...
Did it work for the Tories? A Westminster insider would answer no. I suspect, however, that if it was shown to a focus group of civilians they would understand it much more easily.
That has caused me to pause for thought. I still think it wasn't one of David Cameron's better days but maybe my judgement on his choice of subject is indeed influenced by the thought that a "Westminster village" subject wouldn't resonate 'out there'. So far, it would seem, I was wrong.
