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.

We need to reach out to small 'l' liberal voters who have a modern outlook on life, who want a party that is hard-headed on the economy - more credible on the economy than Labour - but more socially progressive and fairer than the Conservatives.

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.

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.

I am a passionate believer in freedom of speech. I would not support anything which would impinge on aggressive robust freedom of the British press, but when things go wrong and there has been outright illegality, there should be proper accountability.

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.

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.
