Ghana’s President Nana Akufo-Addo has won a second term after a tightly contested presidential election, the country’s electoral commission announced Wednesday, beating long-time opponent John Mahama.

Akufo-Addo, who ran under the platform of New Patriotic Party (NPP), was declared winner of the election after securing 6,730,430 votes ahead of former President John Mahama who polled 6,214,889 votes.

Parliamentary results for the country’s 275 constituencies are yet to be announced, but are expected to be very close. Both parties are contesting some of the provisional results.

Mahama, 62, and Akufo-Addo, 76, are old rivals who have faced off at the ballot box twice before.

Mahama was president for four years until 2016, before being succeeded by Akufo-Addo. Both of those elections were determined by small margins.

Despite the coronavirus pandemic, turnout was high on Monday, with 13,434,574 people voting or 79 percent of registered voters, according to the electoral commission.

Ghana has had seven peaceful transitions of power since the return of democracy more than 30 years ago, and post-electoral grievances have always been pursued through the courts –- a rarity in the troubled region.
