Cape Town - Democratic Alliance leader Mmusi Maimane will ask Parliament's justice portfolio committee chairperson Mathole Motshekga to probe allegations that President Jacob Zuma lied under oath.The case involves the dismissal of former national director of public prosecutions Mxolisi Nxasana, who claimed in court papers this week that Zuma committed perjury over the reasons Nxasana left his post.He was replaced by current NDPP Shaun Abrahams in May 2015 in exchange for a reported R17m settlement."It should be of great concern to Parliament’s justice committee, which the NPA is accountable to, that the Head of State allegedly manipulated facts in order to bulldoze through a predetermined and unethical outcome – the axing of Advocate Nxasana," Maimane said on Thursday.- Read more: Zuma lied under oath about why I left post - NxasanaMaimane said he will ask Motshekga to use the powers afforded to Parliamentary committees to subpoena documents and people, even Zuma, so that this matter can be thoroughly probed.Motshekga himself has been in the news this week after openly calling for a special ANC National Executive Committee sitting to deal with growing calls for Zuma to resign.Motshekga told News24 this week the NEC is the only "competent" body to have a final say on the matter of Zuma's recall. He was the first ANC member to do so.Maimane meanwhile said he would also write to Abrahams to request the National Prosecuting Authority investigate Nxasana's claims."If they are found to be true, this would amount to perjury, which carries the sanction of jail time, a fine or both."Parliament is currently in recess, and will reconvene on May 2.'President's version false'In court papers filed on Wednesday, Nxasana said he entered into the agreement to settle what he considered to be an "intractable, undesirable and ongoing dispute" between himself, Zuma and then Justice Minister Jeff Radebe.He also considered the agreement as an attempt to protect the integrity of the NDPP office."To this day I maintain that I am fit and proper to hold the office of NDPP and would serve again."The president's version in this regard is false. To be crystal clear, I never requested that the president allow me to vacate the office of the NDPP," said Nxasana under oath.
