Prominent businessman Saki Macozoma said he was still an ANC member despite claims that he is funding the Congress of the People.
Questions around Macozoma's political affiliation were raised again in Port Elizabeth on Friday when his name appeared on a Cope guest list as the sponsor of a table for 10 at a gala fundraising dinner.
ANC spokesman Carl Niehaus confirmed that Macozoma had not resigned from the party but said he was "a little bit confused because according to Mbhazima Shilowa, Cope deputy president, Macozoma is with Cope".
"Perhaps he is just allowing his membership to lapse. If that's the case, we wish him well," Niehaus said.
Macozoma told Sowetan that he had not sponsored the R20000 table at the Cope fundraising banquet.
"My wife did that. I am still an ANC member," he said.
Cope spokesman Palesa Morudu confirmed that Macozoma had not joined the new party. Macozoma refused to say if he was planning to join Cope in the future.
Yolisa Macozoma attended the Cope banquet along with recruitment agency owner Pumla Bonani and retired Western Cape crime fighter Manyano Noqayi.
Bonani did not want to talk about her political affiliation.
Other high-profile personalities at the event included South Africa's ambassador to the Netherlands Rob de Vos.
Generations boss Mfundi Vundla and Vecto Finance, a company whose majority shareholder is Jomo Sono, each paid R20000 for tables.
Housing construction company Toro ya Africa, which has received hundreds of millions of rands in government housing tenders in North West, also bought a table.
Although the company was placed under investigation by the provincial legislature in 2006 for building poor quality homes and for allegedly appointing senior government officials as "sleeping partners" in a bid to win housing project contracts, it was later exonerated by the National Home Builders Registration Council.
