President Robert Mugabe of Zimbabwe on Monday fired Emmerson Mnangagwa as vice president, Information Minister Simon Moyo said. Mnangagwa, a 75-year-old former intelligence chief, has been heavily-criticised by supporters of Mugabe’s wife, Grace, who has also been touted as a potential successor to her husband. Moyo said Mnangagwa had exhibited traits of disloyalty, disrespect and deceitfulness. Mnangagwa was appointed vice-president in 2014, taking over from Joice Muguru, who was axed after Grace launched a campaign accusing her of plotting to topple the president. On Oct. 6, Mugabe’s wife accused Mnangagwa of a dark past of clandestine plots, including planning to stage a coup around the time of Zimbabwe’s independence in 1980.
