An anti-graft body says it has new evidence that Angolan President Jose Eduardo dos Santos received millions in kickbacks in the late 1990s, part of an allegedly dodgy debt repayment deal between Angola and Russia. London-based Corruption Watch on Tuesday released a report detailing the involvement of Dos Santos, top oil officials and politicians in syphoning money off debt repayments to Russia through a middleman. This new evidence was presented to prosecutors in Berne, Switzerland on Friday.
