The big risk to British lives in 2013 is in Afghanistan. Our troops, diplomats and aid workers have made a big contribution there. But while there is an end date for Western engagement, 2014, there isn't a proper end game.

The biggest opportunity in 2013 is in Africa. It has seven out of the ten fastest-growing economies in the world. In Nigeria alone there are 100 million people with mobile phones. In total, 300 million Africans - five times the population of Britain - are in the middle class.

The biggest novelty of 2013 will be new leadership in China. Very little is known about the views of the new leaders - who will rule the country for ten years. But we do know they're the first generation of Chinese leaders who have spent the majority of their lives in a China 'opening up' to the rest of the world.
