Chairman of the 13-member committee tasked to investigate what led to the defeat of the National Democratic Congress (NDC) at the 2016 polls, Prof Kwesi Botchwey, has refuted earlier reports that the committee recommended that former President John Dramani Mahama be replaced as flag bearer for the 2020 elections since he lost the 2016 polls as a result of his association with corruption while his arch-rival, Nana Akufo-Addo, of the New Patriotic Party was seen as incorruptible by the electorate.
