I work in lockstep, hand in glove, with the prime minister on these issues, and as we are supportive to the Eurozone so they can sort their problems out, in return they introduce safeguards to ensure precisely what I said: that the single market is not fragmented and that important industries like the financial services industry are treated fairly. Not exceptional treatment, but are just simply treated fairly, on a level playing field within Europe.

We need to teach our kids, because there is such a celebrity culture at the moment, that however rich you are, however famous you are, however glamorous you are, everyone has to live by the same rules.

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.

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.

Politics is a highly tribal business.

One thing I have frankly decided is that when it comes to political reform we have two conservative parties in British politics. Both the Labour and Conservative parties have constantly and repeatedly failed to honour promises they have made about reforming, cleaning, modernising our clapped-out system.

One of the big changes in politics has been because families, individuals, have felt worried, insecure... worried about the economy, worried about their jobs, worried about their kids' futures... actually the disconnect between the public and media discourse and people's everyday concerns has become bigger not smaller.
