I think that the days when newspaper barons could basically click their fingers and governments would snap to attention have gone.

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've just been away for a week, and I dropped my BlackBerry in the sea while I was messing around with the kids, so no one can reach me. Blissful. I heartily recommend it.

Liberalism is a really old British tradition and it has a completely different attitude towards the individual and the relationship between the individual and the state than the collectivist response of Labour, and particularly Old Labour, does.

I totally rule out any arrangements with the SNP — in the same way I rule out any arrangements with Ukip - because there is no meeting point for me with one party that basically wants to pull our country to bits and another party that wants us to pull out of the EU. I would never recommend to the Liberal Democrats that we help establish a government which is basically on a life support system, where Alex Salmond could pull the plug any time he wants.

We are keen to stress that a strong euro zone is good for a strong United Kingdom. It's not for us to write the changes that the euro zone needs to embark on.

I don't even pretend we can occupy the Lib Dem holier-than-thou, hands-entirely-clean-and-entirely-empty-type stance. No, we are getting our hands dirty, and inevitably and totally understandably we are being accused of being just like any other politicians.
