Johannesburg - The Economic Freedom Fighters does not intend on letting Deputy President Cyril Ramaphosa off the hook when it comes to Marikana, insisting that one way or another it will have charges against him instituted."The reason we are opening a case against Ramaphosa is because it is only through criminal investigations that a proper and thorough investigation which is... detailed can be conducted," EFF leader Julius Malema told journalists at a briefing on the Marikana report in Johannesburg."The EFF will leave no stone unturned in ensuring that all who conspired to kill mineworkers are brought to book and will even consider options of private prosecutions if the NDPP [National Director of Public Prosecutions] political appointments refuse to pursue the cases we are going to open."E-mailsThe party believed Ramaphosa had a hand in the ultimate decision taken on August 16, 2012 when 34 mineworkers were killed by police.E-mails sent between Ramaphosa, who was a Lonmin shareholder at the time and then Police Minister Nathi Mthethwa, were read out at the commission.It was believed that Ramaphosa had exerted political pressure on Mthethwa to sort out the strike at Lonmin's platinum mine in Marikana.Malema said his party would be in Marikana on Friday where it would lay criminal charges against Ramaphosa and Mthethwa.The party was also going to lay charges against Mthethwa, directors of Lonmin, former North West police commissioner Lieutenant-General Zukiswa Mbombo and national police commissioner Riah Phiyega.Malema said having a criminal case opened against Ramaphosa meant the police, through the Criminal Procedures Act, would be able to have access to the deputy president's cellphone and e-mail records from that time."This prima facie [case] tells you there is a worse story to be told from Ramaphosa's side."Only police... can unearth that information. We are more than convinced that there is most dangerous information hidden in Ramaphosa's electronics," Malema said.Private prosecutionHe said the EFF did not trust the National Prosecuting Authority to go ahead with the charges against Ramaphosa. If the NPA decides not to prosecute him, the EFF would institute "private prosecution" against him."If you've never seen a successful private prosecution, you are going to see it through the EFF."There is nothing EFF touches which does not become successful."Asked whether the call for Ramaphosa to be prosecuted was based on a grudge because of Malema's expulsion from the ANC, the firebrand leader said no.The EFF was going after Ramaphosa because it believed he conspired to kill mineworkers at Marikana.
