Obama inauguration: Live video
Watch Barack Obama’s inauguration live on politics.co.uk.
The eyes of the world are on Washington as America’s first ever black president is inaugurated.
Lobby groups and campaigners have wasted no time urging the new president to affirm his commitment to their goals, but the new leader already has many different issues in his in-tray.
Apart from the global financial crisis, president Obama will have to address both unpopular wars his country is engaged in and repair America’s reputation around the world after eight divisive years of Republican rule.
President Obama will begin his speech at 17:00 GMT.
