One of the things that I've been doing over the past few years is reevaluating my own powers of political analysis.

I haven't come to the conclusion that centrist politics is wrong or dead. On the contrary. I think it's very much alive - but it needs to be given a renewal, a revival, and a muscularity which it presently lacks.

The trouble is nowadays that parts of the media operate in a very partisan way. There's no point in complaining about it, that's the way it is. But let's be clear, a lot of it is driven by the views of a pretty small number of people, rather than a normal standard of journalism.

If you are trying to take a difficult decision and you're weighing up the pros and cons, you have frank conversations. Everybody knows this in their walk of life.

The art of leadership is saying no, not saying yes. It is very easy to say yes.

The kaleidoscope has been shaken. The pieces are in flux. Soon they will settle again. Before they do, let us re-order this world around us.

I will do what it takes to help Ed Miliband win general election.
