The name Gupta has become synonymous with state corruption in South Africa, as the family allegedly used its friendship with Jacob Zuma when he was president to win contracts and pick cabinet members.

But recent evidence splashed across newspaper front-pages and televised hearings about bribes and sweetheart deals between businessmen and ruling African National Congress officials suggest the rot runs far deeper than most people thought.

The scandals, which have embroiled international companies, threaten to deter investment in a country already battling perceptions of a skills shortage, comparatively high costs and violent crime.

“It’s systemic in that entire systems have been subverted to promote corruption,” said David Lewis, the executive director of South Africa’s Corruption Watch.

“We’re down there right now with the worst.”

The nation has been transfixed by the televised testimony of the former chief operating officer of Bosasa, Angelo Agrizzi, at the Commission of Inquiry into State Capture, a judicial panel investigating corruption. During nine days on the stand, he detailed how the services company bribed Zuma, members of parliament and other state officials.

Heart Bleeds

The commission last year heard the price of a bribe from the Guptas for a government official, in this case the finance minister, could be as high as R600 million ($160 million) – this in a country where unemployment is near a record high of 28%.

Sabelo Legwathi, a 47-year-old factory worker who lives in Kagiso, a township near Krugersdorp west of Johannesburg, said by the time he got home at 7 pm, his family would give him a quick summary of the day’s proceedings: “the entire ANC is going to prison.”

“When I look at my 16-year-old son, I cannot vote for people I know have no interest in his future,” he said.

“My heart bleeds for this generation.”

Cyril Ramaphosa, who replaced Zuma in February last year, insists the party is working to win back the voters’ confidence, and that holding the inquiry is helping to expose possible wrongdoing from the past.

“We are cleansing our country and our institutions,” he said in a recent speech in India.

Election Year

But the revelations may undermine efforts by the ANC, the party Nelson Mandela led to power 25 years ago, to convince voters in elections likely in May that it’s not riven by graft.

Evidence of wrongdoing keeps emerging. Another inquiry into Africa’s biggest fund manager showed that some of the $150 billion under its management went to help allies of the ruling party.

A commission last year detailed how the tax agency was “ dismantled” to help aid alleged graft, while companies such as McKinsey & Co, KPMG LLP, SAP SE and Bain & Co. have also been dragged into the scandals.

McKinsey returned R1 billion to the state power utility after doing work with a Gupta-linked partner, KPMG has shed a 1,200 staff after clients dropped them because its auditors did improper work for the revenue agency and contributed to the collapse of a bank.

Contracts that SAP and Bain won have also been questioned.

‘Quite Horrifying’

“We are still in the process of laying out the extent of the problem and it’s quite horrifying,” said Piers Pigou, senior consultant for southern Africa at the International Crisis Group.

“Things are definitely, definitely very bad.”

While South Africa has struggled with graft before and after the apartheid era, Zuma has been blamed for hollowing out prosecuting agencies and allowing a culture of corruption to flourish during his nine-year presidency.

The former leader, who says the Guptas were his friends, has been charged with corruption related to an arms deal in the 1990s. Zuma and the Guptas deny any wrongdoing.

“There are important instances of corruption pre-Zuma, but Zuma took it to new heights,” Lewis said.

“There was nothing of this scale.”

South Africa’s saving grace may be the robustness of its media and judiciary, Pigou said. They’ve probably helped to keep Africa’s most-industrialized nation from slipping further down the ranks of graft and crime indexes. Transparency International ranked South Africa 73rd in its latest corruption ratings of 180 countries released on Tuesday.

“We have relatively robust remedial systems that are pushing back,” he said.

“The critical thing is what is the president and the executive going to do to navigate going forward to make sure there is some accountability when so many of his fellow travelers are involved?”
