Ghana's opposition candidate and former President John Mahama has promised "a new beginning, a new direction" for the country after being officially declared the winner of Saturday's presidential election. Mahama won with 56.6% against 41.6% for Vice-President Mahamudu Bawumia. It is the biggest margin of victory in the country for 24 years.

John Dramani Mahama, who is returning as Ghana's president eight years after losing power, achieved his political comeback on a promise to mend the West African country's economy.
