Ghana: Akufo-Addo wins presidential election, as President Mahama concedes defeat

Ghana's main opposition leader, Nana Akufo-Addo, has won the country's national election after President John Mahama conceded defeat.

Akufo-Addo said on Twitter that Mahama had called him "congratulating me on winning the 2016 Presidential Election".

Crowds of jubilant supporters gathered outside the house of the 72-year-old New Patriotic Party (NPP) leader, who had already claimed victory on Thursday, a day after the voting took place.

Al Jazeera's Nicolas Haque, reporting from the capital Accra, described the campaign as "bitterly fought".

Earlier, Mahama had appealed for calm and told his supporters he would respect the outcome of the vote whether he won or lost, in comments aimed at defusing tension ahead of the release of official results of the vote.

"I want to assure the nation that we will respect the outcome of the election, positive or negative, and so let us just be calm," he told supporters gathered outside his house.

Mahama, who came to power in 2012 after beating Akufo-Addo, urged voters to "stay the course", promising to deliver more infrastructure projects.
