Johannesburg - The chairperson of the state capture inquiry deputy chief justice Raymond Zondo has dismissed Ajay and Rajesh Gupta's application to cross-examine witnesses.

Zondo said as long as the two brothers were not prepared to return to South African and appear before the commission and give their version of events, he was unable to grant the application.

Duduzane Zuma has been granted permission to cross-examine former deputy finance minister Mcebisi Jonas. Zondo commended him for changing his mind and agreeing to appear before the commission to give his version of events.

Ajay was implicated by Jonas who claimed he offered him a ministerial post in 2015, and R600 million if he took up the job. Former ANC MP Vytie Mentor also told the inquiry that Ajay offered her a ministerial post in 2010 at the family's Saxonworld compound.

Former GCIS CEO Themba Maseko claimed Ajay had asked him to assist the family gain access to GCIS' R600 million media advertising budget.

Maseko said he was fired by former president Jacob Zuma after he refused to help the Gupta family.

The Gupta brothers wanted to cross-examine Mentor, Jonas, and Maseko.  

Duduzane was implicated in testimonies of Jonas and Mentor.

Controversial businessman Fana Hlongwane, who has ties to the Gupta family, has been granted leave to cross-examine Jonas.

Former president Jacob Zuma's previous chief of staff, Laleka Kaunda,  has also been granted permission to cross-examine Mentor.

The commission will on Monday hear evidence from representatives of banks that were involved in the closure of Gupta related bank accounts.

The country's big four banks decided to close Gupta owned bank accounts in 2016 after they detected a number of suspicious transactions.
