Earlier this week I attended the Orwell Prize debate which followed the nominations for best political author, journalist and blogger (the publisher Iain Dale is nominated in the final category).

The debate was entitled: Are Political Parties Bankrupt? I have to admit to a certain frustration with the debate which wasn't caused by a certain tired and emotional contributor. It was caused by the lack of any reference to a practical or institutional point, even by MPs David Davis and Frank Field.

What I mean is, there is evidence that people are disillusioned by political parties, and the economic crisis has perpetuated existing anger at the political class. But if the existing parties are bankrupt entities, what replaces them? It's very well talking about grassroots campaigning and the rise of the internet but people still have to vote for something at the ballot box. And if it's not to be the normal choices of Conservative, Labour and Lib Dem then what? The minority parties might make eye catching breakthroughs at the Euro elections but the language used seemed to suggest some people are giving up on the party system altogether in this country.

Party membership was in decline by 70% from 25 years ago in 2007. There are many people who are politically interested but reject the tribal nature of party politics. But they still need to rally around something. And I can't work out what that is.
