A supporter of former Thai Prime Minister Thaksin Shinawatra sleeps during a rally outside the home of Prem Tinsulanonda, chief adviser to King Bhumibol Adulyadej, which is near Government House in Bangkok April 9, 2009. Thai Prime Minister Abhisit Vejjajiva said on Thursday that a big anti-government rally would be allowed to continue so long as it remained peaceful, while the risk of a turn to violence weighed on financial markets.
