The ANC has accused businessman Kenny Kunene of using cheap publicity stunts to further his "questionable" political ambitions by hurling insults at ANC leaders.
ANC spokesperson Jackson Mthembu says it has become clear that they are dealing with an individual of dubious character, with no basic decency, intent to harming the ANC and its leadership.
Last week, the flamboyant businessman lambasted President Jacob Zuma in an open letter published on The Star's website.
In it he wrote that he had supported Zuma before he became president, but was now disillusioned with his leadership.
Kunene has reportedly joined Julius Malema's Economic Freedom Fighters political platform.
