The government of Thai Prime Minister Thaksin Shinawatra has reportedly banned the country's Buddhist monks from mentioning the administration on state radio.
Radio Thailand officials say the decision came after a monk used a radio sermon to indirectly criticise the ruling party's plan to build a casino.
Thai rights campaigners say the move - which involves the establishment of a committee to monitor all Buddhist sermons on state-radio - goes too far.
The Campaign for Popular Democracy says it's a nonsense to gag monks and even military dictators refrain from meddling in religious affairs.
