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.

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.

I have got instincts that, I think, are very much in tune with people's very keen sense to see something different. I did not dream of being in politics since I was knee-high to a grasshopper. I was not involved in student politics, or not in that partisan way.

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.

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 am quite strict as a dad but I don't want to be censorious.

The UK is not going to leave the European Union. Of course not. We are inextricably wound up with Europe. In terms of culture, history and geography, we are a European nation.
