The Conservative Party is not honouring the commitment to Lords reform and, as a result, part of our contract has now been broken. Clearly I cannot permit a situation where Conservative rebels can pick and choose the parts of the contract they like, while Liberal Democrat MPs are bound to the entire agreement.

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.

The Labour Party has become consumed by collective bile towards... the Liberal Democrats. That portrays a rather nasty arrogance.

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.

Politics is a highly tribal business.

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.

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.
