The National Assembly should investigate "patterns of state capture" by the Indian Gupta family, South Africa's opposition Democratic Alliance said on Sunday.
The DA made the appeal after Jackson Mthembu, Chief Whip of the ruling African National Congress (ANC), voiced support for calls to investigate "patterns of state capture" by the Gupta family, Xinhua reported.
The wealthy Gupta family, which allegedly keeps close ties with President Jacob Zuma, his family and ANC officials, has been accused of exerting undue influence on South Africa's state affairs by offering cabinet posts to ANC officials.
The family has, however, denied the accusation.
Earlier this month, DA Leader Mmusi Maimane submitted a substantive motion in the NA, requesting that the House establish an ad hoc committee to investigate revelations regarding the Gupta family and their illicit influence over the Presidency and Executive.
If Mthembu is serious and not merely offering lip service, he and his caucus should support this motion in the NA and work with the opposition to ensure that this ad hoc committee is free of political influence, the DA said in a statement.
"The Gupta family's influence has infiltrated various government departments and appointment processes, and it is important that an ad hoc committee represented by these portfolios investigate these allegations and report to Parliament," DA Chief Whip John Steenhuisen said in the statement.
If any undue influence or improper conduct is found, the committee should recommend swift action against all those who have compromised their oaths of office, Steenhuisen added.
The committee, he said, must also recommend measures to prevent similar incidents from occurring in future to ensure that a fair South Africa is maintained.
