The Senate whip has set tomorrow and next Wednesday for a general debate in the Senate to grill the government.
At their meeting yesterday, the Senate whips agreed to hold the first round of the debate tomorrow between 1pm and 8pm, said Kamnoon Sitthisamarn, secretary-general of the subcommittee on senate affairs.
The second round of debate will be held on Wednesday after the House of Representatives votes on an opposition censure motion following its own debate on the government's performance.
Senate Speaker Nikhom Wairatpanich will be asked to submit a letter notifying parliament of the new dates, Mr Kamnoon said.
About 50-60 senators are expected to speak during the debate, he said.
Mr Kamnoon said senators will focus on four issues during the debate _ problems with the government's rice pledging scheme and projects to mortgage other crops, unrest in the deep South, water management issues and administrative concerns including tourism, education and drugs.
There is still no word from the government on the new dates set for the debate.
The Senate previously set the dates for its censure debate for tomorrow and Saturday, but the government rejected the request.
Prime Minister's Office Minister Varathep Rattanakorn said the government would be too busy receiving the leaders of various countries visiting Thailand during that period.
The cabinet agreed that next Wednesday would be more suitable, Mr Varathep said.
Mr Nikom said on Tuesday that he accepted the government's rationale although some senators might object to it.
