President Nana Akufo-Addo narrowly beat his long-time rival John Mahama to win a second term, the electoral commission announced on Wednesday.
Ghana’s main opposition party has however rejected the results of the presidential and legislative vote, citing irregularities.
Akufo-Addo, 76, won by a slim margin securing 51.59% of the total votes cast, while opposition leader former President John Mahama secured 47.36%.
Akufo-Addo has called for unity, while giving his victory speech.
“Now is the time, irrespective of political affiliations, to unite, join hands and stand shoulder to shoulder,” he told his cheering supporters.
Local and international election monitors have said that the elections were transparent, free and fair.
But tensions rose on Monday after Mahama,62, claimed to have won a parliamentary majority and warned Akufo-Addo against stealing the vote.
Mahama alleged that Akufo-Addo had harnessed the military in a bid to sway the outcome, a claim the government said was false.
“You cannot use the military to try and overturn some of the results in constituencies that we have won. We will resist any attempts to subvert the sovereign will of the Ghanaian people,” Mahama said.
