Zimbabwe President Robert Mugabe's wife and his best friend and personal financier Gideon Gono have been carrying on behind his back for years, according to reports. Mugabe, 86, found out about the affair from his dying sister in July. The only other person in the room for the deathbed confession, bodyguard Cain Chademana, later died in mysterious circumstances.
