I didn't become leader to transform the Liberal Democrats into an enlarged form of the Electoral Reform Society. It's not the be all and end all for us. There are other very, very key ambitions in politics, not least social mobility and life chances, that I care about as passionately if not more.

Grown-up politicians talk to each other across party lines. Over the last few weeks I have had lengthy conversations with Ed Miliband, David Miliband, with Tony Blair, with Peter Mandelson... talking about Europe, talking about political reform.

After the economic 9/11, we will face a new world order.

For far too long the world's poorest people have seen no benefit from the vast natural resources in their own backyards. It is time to end the injustice where ordinary people are silent witnesses, left to suffer without basic services, as the profits from their countries' assets are hidden and plundered by corrupt regimes.

Joining the Liberal Party was a no-brainer for me... And when you are a young man, you don't get a calculator out saying, 'Am I going to get to power?' You get propelled forward by idealism.

I don't watch a huge amount of telly. I read a lot. I'm reading at the moment 'Freedom,' by Jonathan Franzen, a great big brick of a book, and I'm loving it.

If there's one thing I'm not going to apologise for as the leader of the Liberal Democrats in government after 60 or 70 years of being out of government, it's that you just cannot avoid but deal with the world the way it is.
