In the tussle between President Jacob Zuma and opponents of state capture, the key frontline is a particular meeting between Deputy Finance Minister Mcebisi Jonas, and the head of the Guptas, Ajay Gupta. It’s important, because this meeting holds the key to so much that happened later, the firing of Nhlanhla Nene is surely tied to it and the political act by Jonas of going public about the meeting was surely a galvanising moment in the fightback against the Guptas. But more than that, this meeting actually defines what the fight is about. An attempt, it seems, by the Guptas to literally buy our government, through its constitutionally mandated head. Ajay Gupta has used court papers to deny that he met with Jonas. Jonas has now filed his reply in court papers, as part of the application by Finance Minister Pravin Gordhan, asking a court for a declaratory order that he cannot force the banks to continue their business relationships with the Gupta family.
