Speaking to more than 10,000 supporters at a mass rally Monday in Phnom Penh, opposition leaders Sam Rainsy and Kem Sokha said that unless the ruling CPP cooperated in forming an impartial committee to investigate election irregularities within two weeks, the CNRP will hold nationwide mass demonstrations. “We will demonstrate before [the National Election Commit*tee] announces an official election result,” Mr. Rainsy told the raucous crowd, which packed into Freedom Park and spilled into the surrounding streets.
