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.

One thing I've very quickly learned is that if you wake up every morning worrying about what's in the press, you would go completely and utterly potty.

I care more about getting this right [NHS reform] than I do about getting it done.

You've got some very powerful countries: Poland, the United Kingdom, Sweden and others who have a genuine desire to see the euro zone straighten itself out. It's good for all of us, whether you're in the euro zone or not, to make sure that it doesn't lead to a fracturing.

Although I am a young leader, I actually came to it strangely quite late. I have a different perspective, partly because of my family, partly because of what I did for ten years: negotiating trade deals, working out in Central Asia doing assistance projects.

My head spins. One moment I'm told I'm too edgy, then people say I'm too angry, then that I show too much passion... make your minds up.

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.
