Since 2008, there has been an ongoing political crisis in Thailand in form of a conflict between the People's Alliance for Democracy (PAD) and the People's Power Party (PPP) governments of Prime Ministers Samak Sundaravej and Somchai Wongsawat, respectively, and later between the Democrat Party government of Prime Minister Abhisit Vejjajiva and theNational United Front of Democracy Against Dictatorship (UDD). It is a continuation of the 2005–2006 political crisis, wherein the PAD protested against the Thai Rak Thai (TRT) party government of Prime Minister Thaksin Shinawatra. The PAD's followers usually dress in yellow, called 'the yellow shirts', the royal color of King Bhumibol Adulyadej. The UDD's followers dress in red, widely called 'the red shirts', known as the supporters of the deposed prime minister Thaksin Shinawatra.
