I think it is a simple statement of principle that in a democracy you should make your MPs work harder for your vote and try and get at least majority support in their local area, and that in a nutshell is what AV does.

The Liberal Democrat Party and the Conservative Party come at things very differently when it comes to Europe. When it comes to political reform, we have a much greater tradition in the Liberal Democrats of social justice and fairness than the Conservatives do.

Growth that lasts does not threaten our children's future. It recognises that our planet is a gift that must be cherished. That tomorrow is our responsibility as much as today.

I have got instincts that, I think, are very much in tune with people's very keen sense to see something different. I did not dream of being in politics since I was knee-high to a grasshopper. I was not involved in student politics, or not in that partisan way.

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.

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.

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