We can debate this or that aspect of climate change, but the reality is that most people now accept our climate is indeed subject to change as a result of greenhouse gas emissions.

We fall for... the theories of betrayal very easily, and one of the things that's always depressed me about the left, ever since I started in politics, is their ability to imbibe the propaganda of the right and regurgitate it to the left.

The Iraq Survey Group has already found massive evidence of a huge system of clandestine laboratories.

The great advantage of the Lib Dems is precisely that no-one knows what they stand for.

For me, 9/11 was a game changer. It altered my perception of the security threat we faced. I took the position that Britain should be shoulder to shoulder with the U.S. It was a big decision; I didn't take it lightly, or in ignorance of its consequences. It's a big commitment for a country to give, but I believed it was the right thing to do.

Politics may be the art of the possible; but, at least in life, give the impossible a go.

I say to the Taliban: surrender the terrorists; or surrender power. It's your choice.
