Atul Gupta has denied claims that his family orchestrated a campaign around the term "white monopoly capital" with the help of UK based public relations firm Bell Pottinger.
The Guptas and the firm have been under fire over alleged attempts by the family to capture government.
Gupta was interviewed by BBC Radio 4 on Tuesday to discuss the alleged campaign to exploit racial tensions in South Africa.
In the interview, he said the firm was only ever hired to do public relations for Oakbay.
I don't know where this narrative comes from, white monopoly capital if you go to any such revolutionary speech in this country always existed. There is nothing like that, I don't know where this narrative comes from.— Atul Gupta
He has defended Bell Pottinger asserting that it is a credible firm.
Speaking on the Gupta leaks he suggests the emails are not authentic.
There is no authenticity of Gupta leaks at all, they are all everyday perception mongering to drive their own agenda. No one has authenticity of these mails.— Atul Gupta
