My immediate reaction to the leader’s debate that has just finished on ITV is “whey hey!!!”.

Brown gave a good performance I think but is likely to only reinforce people’s existing views of him.

David Cameron was very poor. A flat, almost amateurish, performance. Surprisingly bad.

Nick Clegg gave the better performance. He was more human, more energised, and gave the clearer answers. Could have been a bit sharper at times and repeated the same points a few too many times – but overal reallly really good.

But more siginificant I think than the individual performances is how this debate will shape the campaign. It is clear that Nick Clegg and the Liberal Democrats are now in many ways setting the agenda. Not only is the party now inserted into the debate on equal terms with the other two, but is actually forcing the other two to respond. Why else are Gordon and Dave so keen to say “I agree with Nick”?

I am very very excited about our prospects after this. Game on!
