Zimbabwean President Robert Mugabes wife has had a fling with one of his best friends and the countrys top banker for five years,a media report said. Grace Mugabe,41 years younger than the 86-year-old President,has,in fact,spent the past five years cuckolding him with Gideon Gono,head of the countrys central bank,the Daily Mail reported. The couple would meet as often as three times a month either at her dairy farm or in expensive hotels in neighbouring South Africa,the report said. Mugabe finally found out about the affair in July when his sister Sabina revealed the scandal on her deathbed. Since then his most-trusted bodyguard Cain Chademana,who is said to have told the furious President that he knew of the affair,has lost his life amid suspicions that he was poisoned. Gono,50,is now said to fear for his safety. Once he (Mugabe) hears something like that,I think someone will go to meet God, a Zimbabwean intelligence official was quoted by the British newspaper as saying. However,its not the first time Mrs Mugabe,who is widely reviled inside Zimbabwe for her lavish tastes and expensive shopping sprees,has conducted affairs behind her husbands back. One former lover,Peter Pamire,died in a mysterious car accident. Another,James Makamba,fled the country. Gono has known Mrs Mugabe,who married the President in 1996,for at least 15 years and they are partners in a number of business enterprises. He is a pillar of the Zanu PF party which is in power since Zimbabwes independence from Britain in 1980. A senior official in Gonos office told South Africas Sunday Times newspaper: Mugabe trusted Gono. He even thought our boss was taking care of the first lady,keeping a protective eye on her so that she could not again be adulterous."
