Congratulations to Barack Obama - great victory based on building fairer economy and optimism about what politics can achieve.

Margaret Thatcher was the first political leader in any major country to warn of the dangers of climate change

One of the drivers of displacement and potential conflict over the next 10 to 20 years will be climate (change) - resource scarcity, climate change is going to compound the cocktail that's driving war and displacement.

And think of how we challenged the idea of a male dominated Parliament with All-Women shortlists and made the cause of gender equality central to our government. We were right to do so.

Think of how we challenged the impression that we taxed for its own sake and that we were hostile to business. We were right to change.

Congratulations to Barack Obama - great victory based on building fairer economy and optimism about what politics can achieve.

We don't compete in the world by offering tax advantages to a few that we don't give to all our citizens and businesses
