Five things we can learn from today's Prime Minister's Questions:
1 - MPs can be very loud - this was perhaps the noisiest session I have ever heard.
2 - Ed Miliband is trying very hard to get on the front foot over party funding after a terrible week
3 - David Cameron is still attempting to insert an answer on unions bankrolling Labour - no matter what the question
4 - Labour are now targeting the hedge funds they claim are funding the Tories
5 - People in the country might think there are more important issues to discuss during PMQs
