There can be little doubt that tenderpreneur Hendrick Kganyago's payment of three companies linked to EFF leaders related to his fuel supply to the City of Tshwane.Contracts in other areas where his companies are active may have featured too.READ: Tender comrades part 2: Tshwane tenderpreneur's R15m 'EFF tithe'The City advertised the tender for a new multi-year contract where he was the incumbent in mid-2018.His payments, R15m in total to the end of August this year, started shortly after. Two early transfers were even referenced "fuel payment".Round amounts can be a dead giveaway that no legitimate goods or services are delivered. Kganyago's payments were perfectly round at first: eleven tranches of R250 000, R500 000 and R1m each until November 23 last year.Then followed the apparently clumsy disguise of tacking small change onto those amounts, such as with an oft-repeated transfer of R501 200. This started on December 7, the first tranche after we exposed City of Johannesburg contractor Afrirent's payments to Julius Malema's Mahuna Investments on November 29.And while Kganyago might claim that he paid one of Mahuna, Santaclara Trading or DMM Media while unaware of its EFF links, such a claim would be unsustainable given that he paid all three.In the alternative, Kganyago might claim that he was making legitimate donations to the EFF. If so, he would have to explain why he paid it to obscure companies linked to EFF leaders rather than party accounts. The intent to disguise seems even clearer.These factors suggest corruption, but for what purpose?There is a growing body of evidence that EFF leaders are extracting "rent" from procurement streams in areas where they have, or may be perceived by contractors to have, sufficient power to influence procurement outcomes. This would apply pertinently to the cities of Johannesburg and Tshwane, where the EFF emerged as kingmakers after the 2016 municipal elections.ALSO READ: Tender comrades part 1: Trailing the Juju tractorAre contractors paying the EFF or its leaders to intervene in specific tenders? That seems likely, given both the timing of some payments and what we have heard about EFF central command member Marshall Dlamini's meetings with officials in both cities (which he denies). DMM Media is connected to Dlamini.But beyond that, the ongoing nature and regularity of Kganyago's payments suggest the same "mutually beneficial symbiosis" that Judge Hillary Squires found had existed between Schabir Shaik and Jacob Zuma.Shaik supported Zuma financially for an extended period, while Zuma allegedly used his position to advance Shaik's business interests through specific interventions.This is consistent with what a former Johannesburg executive told us about Dlamini and Afrirent: "He said to me there's this tender coming – we want a company that works with us (our emphasis) to get it."Kganyago's payments to Mahuna, Santaclara and DMM Media declined after Tshwane awarded the tender to his Balimi Barui Trading (BBT).During the six months before the award, while Kganyago was the sole incumbent, he paid them an average of R1.8m a million a month. In the first six months of the new tender, when the contract was split between BBT and two others, he paid them a little over R600 000 a month – roughly a third.So it looks like Kganyago's "obligation" reduced along with his takings from the City. Kickbacks – secret, illicit cuts from revenue – in the purest sense of the word.But did the EFF or its leaders exercise illicit power to advance Kganyago's business interests?The extent of the City of Tshwane's errors – not calling BBT's bluff, which got it ranked highest despite being damn expensive, and then overpaying BBT and the other two successful bidders by R2.6m each month – suggest that possibility, but that smoking gun has yet to be found.But that is not a necessary condition.The Prevention and Combating of Corrupt Activities Act provides that the offence of corruption arises not only where power is, in fact, abused in return for gratification. If gratification was accepted for the exercise of power, it is no defence to say that you did not have the power, did not intend to use it or did not use it.Kganyago and the EFF have not deigned to respond to us. They owe the nation an answer. And, we think, the courts.The amaBhungane Centre for Investigative Journalism, an independent non-profit, produced this story. Like it?
