Supporters of National Democratic Congress (NDC), the party of the late Ghanaian President John Atta Mills, carry a poster of their candidate John Dramani Mahama as they celebrate his victory along a street in Accra December 9, 2012. Ghana's main opposition National Patriotic Party said on Sunday the country's presidential election had been manipulated, raising concerns about the outcome of the poll in a nation seen as a bulwark of democracy in an unstable region.
