A probe into tenders awarded to companies said to involve African National Congress Youth League (ANCYL) president Julius Malema is expected to be completed by the Office of the Public Protector Thuli Madonsela by the end of June.

The investigation relates to tenders that were allegedly awarded by ten municipalities.

Public Protector spokesperson Kgalalelo Masibi said on Monday that Madonsela had "promised" that an "interim" report would be released by June 30.

Madonsela's office announced in March that it intended investigating tenders awarded to the company SGL Engineering Projects, on whose board Malema apparently served as a director.

These tenders included a R2,1-million sewerage upgrade; a R39,3-million sewerage reticulation project; a R27,9-million street paving and drainage contract; a R28-million tender for several municipal infrastructure projects; and a R2-billion roads tender.

At the time, Masibi said that the decision to investigate followed complaints by AfriForum Youth and the Congress of the People.

The probe focused on whether there was improper conduct in the awarding or management of the contracts.

Malema had denied receiving any lucrative tenders including any through SGL Engineering Projects.
