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

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.

Over the next few days we want cities, towns and villages across the UK to send a message to Scotland: stay with us.

We can only converse if we can speak the same language. So if we are going to build One Nation, we need to start with everyone in Britain knowing how to speak English.

This is a proud day and an important step forward in the fight for equality in Britain. The overwhelming majority of Labour MPs supported this change to make sure marriage reflects the value we place on long-term, loving relationships whoever you love.

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.

Let the message go out - a new generation has taken charge of Labour which is optimistic about our country, optimistic about our world, optimistic about the power of politics. We are optimistic and together we will change Britain.
