ANC treasurer-general Dr Gwen Ramokgopa has appealed to business leaders who are members of the party to openly fund the organisation and “not in dark corners, under the table or in brown envelopes”. She was speaking at the provincial ANC's gala dinner at Boardwalk Hotel in Gqeberha on Friday evening ahead of the ANC's review of the 2019 manifesto to be held at Isaac Wolfson stadium on Saturday.
