An economist at KPMG, Christie Viljoen, says South Africa has slipped to number 3 on the African continent, and is not only behind Nigeria, but now also Egypt. That's according to Viljoen's analysis based on the International Monetary Fund's latest figures. South Africa lost its status as the continent's largest economy in 2014, when it finished an exersice to rebase its economic data. Now, KPMG notes the IMF suggests that Egypt has overtaken South Africa as the second largest economy in Africa
