Luanda Leaks Corruption Files 'Tip of the Iceberg,' Angolan Campaigners Say Anita Powell JOHANNESBURG - Angolan activists say the recent "Luanda Leaks" investigation-- which uncovered billions of dollars' worth of unscrupulous business dealings that made the daughter of Angola's longtime president, the richest woman in Africa-- is just the tip of the iceberg when it comes to corruption in the oil-rich African country. When they came out last month, the 700,000 documents in the "Luanda Leaks" investigation-- carried out by the International Consortium of Investigative Journalists-- shed light on a tangled web of illicit dealings centered around Isabel dos Santos, the daughter of former Angolan president Jose Eduardo dos Santos. But, Angolan activists say there's much, much more to come. Peace activist Daniel Ntongi-Nzinga says corruption in the southern African country neither starts nor stops with the former president's daughter. "I don't see a single day that newspapers don't talk about Isabel Dos Santos," he said. "Almost every day, more than two or three articles will come out. More than five or six statements are being done on Isabel. I find it very strange. But the billions that disappeared in Angola, it did not all go with Isabel. There are many others." Isabel Dos Santos has repeatedly denied the corruption allegations -- including to VOA -- and claims the legal case against her is politically motivated. .
