Ghana's electoral commission has declared ex-President John Dramani Mahama the winner of the presidential election, securing 56.55% of the vote. His main rival, Vice President Mahamudu Bawumia, conceded defeat, acknowledging the need for change amid a severe economic crisis. Mahama, who previously served from 2012 to 2016, promises governance reforms and a $10 billion investment in infrastructure to address the country's challenges.
