Interior Minister Sar Kheng on Monday warned of “trouble” if opposition leader Sam Rainsy does not return to the negotiating table to hammer out a solution to a stalemate between the CPP and the opposition over irregularities during the July 28 national election. Mr. Kheng made his comments after he met privately and separately on Monday with the French and German ambassadors, and after the National Election Committee (NEC) said on Sunday that plans for an inter-party committee to investigate alleged election irregularities had been abandoned.
