Deputy President Jacob Zuma appeared in an upbeat mood on Tuesday when he faced questions by MPs in the National Council of Provinces, saying there was no reason for him to step down from his position. Zuma has been dogged by controversy since National Director of Public Prosecution Bulelani Ngcuka announced that Zuma would not face prosecution for anything related to the multimillion-rand arms deal, despite there being prima facie evidence against him. The deputy president has accused Ngcuka of finding him guilty of corruption without having the necessary evidence.
