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 don't watch a huge amount of telly. I read a lot. I'm reading at the moment 'Freedom,' by Jonathan Franzen, a great big brick of a book, and I'm loving it.

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.

Most of what needs to be changed in the euro zone can be done without treaty changes. The demand for treaty change is as political as it is legal and I don't think it's going to happen soon.

My dad's side of the family had lots of artists and musicians. There's an emotional, quite sentimental quality to Slavic culture. It's very open, it loves art, it loves music, it loves literature. It's very warm, it's very up, it's very down. I would celebrate that.

The Liberal Democrats will add a heart to a Conservative government and a brain to a Labour one.

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.
