The ANC said on Friday that it is gravely concerned by the leaked Gupta emails alleging influence-peddling by friends of President Jacob Zuma, deepening a divide in South Africa's ruling party over its leader.
Some media outlets had reported on Thursday they had access to over 100,000 leaked documents and emails that showed improper dealings in lucrative government contracts by business friends of Zuma.
The latest allegations of influence-peddling may deepen divisions in the ANC as factions battle for control ahead of a party conference in December where a successor to the beleaguered, scandal-plagued Zuma will be chosen. Zuma can remain as head of state until an election in 2019.
Zuma and the Gupta family, wealthy Indian-born businessmen whose companies have contracts with state-owned firms, have not commented but have denied similar allegations in the past. Reuters could not independently verify the new allegations.
"These reports contain very worrying claims about the nature of the relationship between government and private interests," the ANC said in a statement, calling on government to urgently establish the veracity of the leaks.
"The ANC views these allegations in a very serious light as, if left unattended, they call into question the integrity and credibility of the government."
The statement appeared to contradict Zuma, who said at a parliamentary session on Thursday that he was not interested in "hearsay" published in newspapers.
A backroom schism in the ANC over Zuma has burst into the open in recent weeks as his opponents seek to oust him or ensure his chosen candidate does not take over the reins.
ANC split in two by Gupta emails
"This week we have seen there are clearly two ANCs," said political analyst Daniel Silke.
"One ANC sees very little wrong with crony capitalism, kickbacks and shady payments. The other ANC sees the reputation of the party among the electorate disintegrating and fear the real possibility they could lose power."
The DA has made upbeat comments about unseating the ANC in 2019, an unthinkable scenario a few years ago for a party that has led comfortably since it swept to power under Nelson Mandela at the end of apartheid in 1994.
Zuma survived a call to resign at an ANC meeting last week due to disputes over political appointments and his friendship with the Gupta family.
Parliament is expected to hold a no-confidence vote in Zuma later this year but he has survived similar attempts before.
When Zuma sacked respected finance minister Pravin Gordhan in March, three of the top six members of the ANC, including Ramaphosa, openly criticizing his decision, breaking the party's strict rule of showing unity in public.
Gordhan's replacement Malusi Gigaba has been accused of having close ties to the Guptas. Gigaba said on Friday that he had done nothing wrong and the leaked documents would not link him to the family.Suggest a correction
