Barack Obama has been re-elected as the President of the United States.
Obama secured the 270 votes in the electoral college he needed to beat Republican Mitt Romney and begin his second term in the White House.
In his victory speech in Chicago, Obama said: 'We've got more work to do. While our journey has been long, we have picked ourselves up, we have fought our way back and we know in our hearts that for the United States of America, the best is yet to come.'
