Papua New Guinean Prime Minister James Marape has demanded a preliminary report by Wednesday from the investigation into corruption concerns involving a key figure in the Pacific nation’s successful bid to join the National Rugby League competition. Wapu Sonk stood down from the PNG NRL franchise board on Friday after an investigation by this masthead into whether he attempted to benefit from a deal between the country’s national oil and gas company and a Chinese government-controlled firm. His position as managing director of state-owned Kumul Petroleum Holdings has now also come under scrutiny, with Marape announcing the appointment of a new chairman “to lead a full and independent review of the issues raised.” “This matter must be resolved quickly, clearly, and professionally. I expect a preliminary report on my desk when I return to Port Moresby on Wednesday,” Marape said.
