Cape Town - National Prosecuting Authority head Shaun Abrahams must drop the appeal against the reinstatement of 783 fraud and corruption charges against President Jacob Zuma, and resume the case against him immediately, a group of United Democratic Front (UDF) veterans demanded on Monday.It must also start prosecuting the local and international board chiefs, government officials and civilians allegedly implicated in bribery and corruption in South Africa.The call was made in a letter the veterans wrote to Abrahams and delivered to his Western Cape prosecutions director Rodney de Kock in Cape Town on Monday."We demand that you immediately prosecute Jacob Zuma and withdraw your appeal," read the letter signed by 50 veterans of the UDF anti-apartheid movement, and read to De Kock by one of the signatories, Madoda Cuphe.The letter was a precursor to the greater anti-Zuma march to Parliament on Monday, and comes a day before the vote on a proposed motion of no confidence in Zuma.Parliament's suspended head of Protection Services Zelda Holtzman and activist Zackie Achmat were among those delivering the letter.Demand for prosecutionsStepping away from a meeting to accept the letter for Abrahams, De Kock joined them in the NPA's boardroom as they made their demands."Since the reports of the Public Protector, [SA Council of Churches] and the academics, combined with a range of judgments in the High Court, Supreme Court of Appeal and the Constitutional Court on matters ranging from the SABC, [Passenger Rail Agency of SA], Eskom, Cash Paymaster Services, Transnet, Water Affairs Ministry, [SA Revenue Services], among others, the MPS has been glaringly absent. All these have been substantially cemented by the #GuptaLeaks, which makes your silence complicit," read Cuphe.
