One of Cambodia's most stridently independent newspapers, The Cambodia Daily, published its last edition on Monday with the headline "Descent Into Outright Dictatorship" as it closed amid a crackdown on critics of Prime Minister Hun Sen.

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."

Its final front page led with the arrest on Sunday of Cambodia's main opposition leader, Kem Sokha, who was accused of treason in a significant escalation of the campaign against Hun Sen's opponents. The paper also reported on its own closure.
