Casting his vote, Mr Mahama said he had no regrets over his first term in office

Ghana’s President John Mahama has said that he will respect the outcome of the tightly contested election.

He also said in a tweet that the Electoral Commission should be allowed to carry out its mandate.

Local media are reporting that main opposition candidate Nana Addo Dankwa Akufo-Addo, 72, has an unassailable lead.

Final results are expected before the end of the day.

The electoral commission announced Thursday that it was manually verifying the results because its electronic system had been targeted by hackers.

The ruling National Democratic Congress (NDC) candidate’s quest for a second term is facing a strong challenge from a revitalised New Patriotic Party (NPP).

A run-off will be held later in the month if neither of the two main candidates secures more than 50{d59e984f9fbc5c09e4ab0305e27bfa5819922b7230cd324f89a660f78358ca33} of the votes.

The campaign was dominated by Ghana’s faltering economy.

In the previous election in 2012, Mr Mahama defeated Mr Akufo-Addo by less than 300,000 votes.
