Do I know I'm right? Judgements aren't the same as facts. Instinct is not science. I'm like any other human being as fallible and as capable of being wrong. I only know what I believe.

The first rule in politics is that there are no rules, at least not in the sense of inevitable defeats or inevitable victories. If you have the right policy and the right strategy, you always have a chance of winning. Without them, you can lose no matter how certain the victory seems.

A lot of the politics that is going on left and right at the moment is more about a protest, which we should respond to. It's not often about a policy. And that's why what you get is this strange coalition of different views of what the future should be, coming together in alliance to protest against the status quo.

Society works by putting opportunity and responsibility together.

We need to develop the new green industrial revolution that develops the new technologies that can confront and overcome the challenge of climate change; and that above all can show us not that we can avoid changing our behaviour but we can change it in a way that is environmentally sustainable.

I think we've, again, got to be extremely careful; otherwise we'll misunderstand what's going on in Iraq and in Syria today. Of course, you can't say that those of us who removed Saddam in 2003 bear no responsibility for the situation in 2015.

The first big choice: a government with the strength to deliver stability, or a government that takes the country back to boom and bust.
