Opposition leader leader Kem Sokha was arrested in a police raid on his home early on Sunday after Hun Sen accused him of treason with the backing of the United States.

"CNRP shall be dissolved if it keeps defending Kem Sokha and keeps saying that this country is a dictatorship", Hun Sen warned during a meeting with 4,000 workers on Sunday.
The English-language paper had been given a deadline of one month to pay $6.3 million for years of back taxes, which the publication disputed and described as "astronomical".
