JOHANNESBURG (Reuters) - A top official in South Africa’s governing African National Congress was granted bail on Friday, in a graft case that has highlighted divisions within a party whose dominance has been unchallenged since the 1994 end of white-minority rule.Ace Magashule, secretary-general and one of the top six most powerful officials of the ANC, faces allegations related to a contract to audit houses with asbestos roofs awarded while he was premier of the Free State province. He was not asked to plead in his first court appearance on Friday, where he faced 21 charges of corruption and fraud, but has previously denied any wrongdoing. The charges have put him on a collision course with President Cyril Ramaphosa, who has pledged to clean up the ANC’s image with a tough stance on corruption, but whose detractors accuse him of using it to sideline his opponents. Magistrate Amos Moos at the Bloemfontein Magistrate Court set the bail for Magashule at 200,000 rand ($12,823.72) and ordered him to appear before the court on Feb. 19. “We expect to add three more accused on the charge-sheet,” the National Prosecuting Authority said in a statement.
