I am quite strict as a dad but I don't want to be censorious.

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.

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.

I work in lockstep, hand in glove, with the prime minister on these issues, and as we are supportive to the Eurozone so they can sort their problems out, in return they introduce safeguards to ensure precisely what I said: that the single market is not fragmented and that important industries like the financial services industry are treated fairly. Not exceptional treatment, but are just simply treated fairly, on a level playing field within Europe.

After the economic 9/11, we will face a new world order.

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

For far too long the world's poorest people have seen no benefit from the vast natural resources in their own backyards. It is time to end the injustice where ordinary people are silent witnesses, left to suffer without basic services, as the profits from their countries' assets are hidden and plundered by corrupt regimes.
