Nairobi — Former Ghanaian President John Mahama is one of the main challengers of ruling party candidate Mahamudu Bawumia in the West African nation’s December 7 national elections. If he wins, Mahama vows to cultivate a 24-hour business environment to bolster job creation and improve an economy recovering from a $30 billion external debt default in 2022. Bawumia, the current vice president, says despite the recent woes associated with the post-COVID pandemic and some internal pressures he too is committed to strengthening the economy.
