The Public Protector will conduct a preliminary investigation to determine the merits of some of the allegations that have been published as part of the #GuptaLeaks saga that point to issues at Eskom, Prasa and Transnet.

These allegations point to improper or dishonest acts or offences with respect to public funds at the state-owned enterprises as well as improper or unlawful enrichment by certain public officials at these institutions, the Office of Public Protector Busisiwe Mkhwebane said in a statement on Wednesday night.

Aside from the #GuptaLeaks, the investigation will also look at the controversial re-appointment of Brian Molefe as head of Eskom.

Former Public Protector Thuli Madonsela's initial state capture report about alleged improper and unethical conduct by President Jacob Zuma and other state functionaries, relating to the Gupta family, was released last year.

A review application by Zuma on the recommendations of that report is expected to be heard in October.
