I’ve written more than a few times before about my views on the behaviour of MPs at set-piece events like Prime Minister’s Questions (in short: abysmal!). Well – it looks as if Ed Balls at least may have got his comeuppance – being accused all over the media of shouting “so what?” when Cameron was speaking in the budget debate about the high levels of taxes under Labour. Not exactly a clever thing!

I understand his defence is that he actually said “so weak” – but in the end if you live by the sword, you die by the sword – and if you engage in the sort of boorish behaviour that wouldn’t be tolerated in a normal place of work, well it’s your own fault if it goes wrong.
