John Dramani Maha
Ghana's presidential election has been won by incumbent President John Mahama, the electoral commission has announced.
The electoral commission said that Mr Mahama had won 50.7 per cent against his NPP rival Nana Akufo-Addo on 47.74 per cent.
The announcement came hours after the opposition accused the governing party of conspiring with commission staff to fix Friday's poll.
BBC repoted that Police in the capital Accra fired tear gas to disperse opposition protesters from outside the commission's offices.
Roads around the electoral offices were also barricaded by police as the results were announced.
"Ladies and gentlemen, based on the results given, I declare John Dramani Mahama president-elect," electoral commission chief Kwadwo Afari-Gyan told journalists.
Ghana, one of the world's fastest growing economies, is regarded as one of Africa's most stable democracies.
Mr Akufo-Addo lost the 2008 presidential poll by one percentage point, but accepted the result.
However, on Sunday his party said they had "enough concrete evidence" to prove that he actually won this year's election.
"The ruling NDC conspired with certain EC staff in constituencies across the country to falsify the election results and thereby abuse the mandate of the people of Ghana," the party said.
"It was this planned, systematic stealing of votes at the collation level that was, thankfully, discovered in time."
The party cited discrepancies between initial tally sheets and the results reported in the media.
