Thailand's main opposition party has announced the resignation of all its MP's to protest against a government they claim is illegitimate. The announcement comes as Prime Minister Yingluck Shinawatra proposed a referendum on her future and promised to resign if that was what the people wanted. Anti-government protester leaders have meanwhile called for a final demonstration today to force Yingluck to stand down. Protesters have been on the streets of the capital for weeks, clashing with police and vowing to eradicate the influence of Yingluck's self-exiled brother, the former Prime Minister Thaksin Shinawatra. Kim McQuay, an expert in Bangkok, comments on what may happen next.
