Finance Minister Pravin Gordhan has said that his stay in office is determined by President Jacob Zuma.
Gordhan has been at the centre of a political storm, amid claims that the Hawks are targeting him for political reasons, over a unit set up at Sars while he was its commissioner.
Speaking at the Open Book Festival in Cape Town, Gordhan touched on the Sars investigation and other questions from the audience.
Gordhan says he feels it is unnecessary to conduct a judicial inquiry into South Africa's four major banks for cutting ties with the Guptas.
This after Mineral Resources Minister Mosebenzi Zwane jumped the gun by making the controversial statement from which President Zuma and ANC members later distanced themselves.
Asked about factionalism in the ANC, Gordhan said that there is a need for change within the ruling party, reports EWN's Kevin Brundt.
At the same time, the Daily Maverick's Ranjeni Munusamy says Gordhan appears to be much more "bullish" in recent weeks.
Munusamy says that Gordhan is deviating from the norm that ANC officials be diplomatic and tread carefully.
He's also talking more boldly on pertinent issues in the public domain...He seems very much willing to bring the fight.— Ranjeni Munusamy, Associate Editor at the Daily Maverick
According to Munusamy, the dynamics in the ruling party remain unclear at this stage as factional battles and power grabs continue.
