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.

What I hope is in five years' time, I can go to the British people in the election and say: Lots of you doubted that coalition politics worked, but it has worked.

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.

I don't want to clip on the armour every morning. I've seen some politicians do this and they get a bit mangled and bitter. I just refuse to do that. I refuse to be angry or bitter or complain, and I remain open. I may sometimes be a bit too open but I'm not going to change that one bit.

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.

You see people literally in a different galaxy who are paying extraordinarily low rates of tax.

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.
