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.

When I became leader, I made very clear I was not going to choose the easy life. I have always taken risks. I don't like comfort-zone politics.

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.

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.

Most people in the country would think the diamond jubilee is a wonderful occasion for us to celebrate together as a community and as a nation. But I suspect that most people in the country would think, given that there is very little money around, that this probably would not be the top of their list of priorities for the use of scarce public resources.

If there's one thing I'm not going to apologise for as the leader of the Liberal Democrats in government after 60 or 70 years of being out of government, it's that you just cannot avoid but deal with the world the way it is.

I firmly believe that the principles behind Contraction & Convergence provide the best long-term framework for a fair and equitable climate change mitigation policy
