Cape Town - Documents which will prove that Nelson Mandela Bay Metro's security head Linda Mti's appointment was above board appeared to be lost in the mail, according to the spokesperson for Co-operative Governance and Traditional Affairs in the Eastern Cape."The metro confirmed that it did send the documents by registered mail," said Mmamkeli Ngam, spokesperson for Cogta MEC Fikile Xasa."We are going through a process to establish whether the documents were received," said Ngam.But Democratic Alliance mayoral candidate Athol Trollip rejected this."In this day and age when people start using the Post Office as a reason why the MEC didn't get it... " said Trollip.Trollip has alleged that the appointment was irregular because Xasa had not been informed of the appointment within 14 days as required. If this is the case, it could be a violation of the Municipal Systems Act, the DA believes.Not suitable for the jobTrollip also objected to Mti's appointment on the grounds of his criminal record for drunk driving convictions in 1992 and 2009 and that he is under investigation by the National Prosecuting Authority for allegedly benefiting from a R1bn tender awarded to Bosasa facilities management while he was prisons commissioner.According to the DA this does not make him a suitable person for the job of head of safety and security in the metro.Earlier this week Trollip shared a reply to a question he put to Xasa in the Eastern Cape legislature. Trollip wanted to know whether Xasa had approved the appointment of Mti, as required by the Act.Xasa said he had not received the information relating to Mti's appointment.He explained in the reply that initially, a Mr Brown was appointed as head of safety and security for the metro on May 9 2014. The MEC confirmed compliance with that appointment on November 2 2014.Brown later opted for a lower position within the metro and so Mti was appointed on May 9 2016 on a five-year contract.Former colleagues"Let me indicate that as executive authority of the department that I have not yet received any submission relating to wrongdoing on the part of the official. I can only act on the basis of information forwarded to my office in this regard," a transcript of Xasa's reply to the legislature, provided by Trollip, read."The department did not receive the documents relating to the appointment of Mr Linda Mti. Therefore I won't be able to state whether the necessary prescripts were followed or not."Trollip believes that mayor Danny Jordaan, who was appointed in 2015, snuck Mti in and now wants Mti, a former African National Congress chairperson for the province, to be suspended until the matter is cleared up.Mti and Jordaan worked together on the 2010 World Cup Local Organising Committee - Jordaan as CEO and Mti as head of safety and security.The metro insists that it sent the documents to Xasa's office, hence Xasa's office's efforts to track down the missing mail.A privilege to have MtiKupido Baron, a spokesperson for the metro, told News24 that all the documentation, as specified in regulations regarding the appointment of senior managers, was sent to Xasa's office."Correctly so, no mention is made of allegations on the documentation as untested claims should not be used as a measure to disqualify qualified and competent individuals from job opportunities," he said on Monday.The metro also regarded the drunk driving issue as being in the past."Mr Mti has extensive experience in safety and security for national government departments and we are privileged to [have] him in our service."NPA spokesperson Luvuyo Mfaku said the Bosasa probe was continuing and that a new investigator had been appointed.
