Even by the most bizarre standards of Thai politics, today's no-confidence motion against the Government of Prime Minister Chuan Leekpai looms as a classic.
Mr Chuan, considered the most honest politician of his generation, faces a censure motion from an opposition that includes some of the most disgraced.
The quiet-living lawyer has long stood for open and clean government, yet faces questioning from career politicos who stand for little more than money politics.
Leading the charge is expected to be his predecessor, Chavalit Yongchaiyudh, a retired general whose rule foundered on claims of mismanagement and cronyism and coincided with the worst economic collapse since World War II.
Along with other opposition chiefs, he has promised revelations of alleged government corruption, incompetence and abuses by the police.
The motion has arisen despite a strengthening of the baht in recent weeks and an unprecedented level of international support for Mr Chuan's steady if low-key rule.
