A five-year-old internal report into irregularities at the National Lotteries Commission (NLC) ‘has gone off like a nuclear bomb’, according to a source at the troubled institution.

AmaBhungane, which obtained a copy of the report, set off the reaction with questions to key players implicated in the report – including outgoing NLC chair Alfred Nevhutanda and chief executive Thabang Mampane.

The 2015 report by attorney Trevor Bailey identified irregularities at the NLC and urged further action against Nevhutanda and chief executive Thabang Mampane.

Neither the NLC board nor the responsible Minister, Rob Davies, implemented Bailey’s recommendations.

Instead, Bailey’s report was quashed and chief risk officer Bathabile Kapumha was effectively hounded out, while others who had supported her left or were sidelined, notes amaBhungane.

The report has re-emerged at a time when Nevhutanda, whose term expires at the end of the month, appears to be locked in a bitter battle with Davies' successor, Ebrahim Patel, over the future of the NLC – and it's controversial past.
