In Thailand politics, the Finland Plot, Finland Plan, Finland Strategy or Finland Declaration (Thai: แผนฟินแลนด์, ยุทธศาสตร์ฟินแลนด์, ปฏิญญาฟินแลนด์) are names of a controversial conspiracy theory espoused by Sondhi Limthongkul and supporters affiliated with the People's Alliance for Democracy (PAD) in 2006 describing a plot allegedly developed by Thai Prime Minister Thaksin Shinawatra and former left-wing student leaders to overthrow the Thai monarch, take control of the nation, and establish a communist state. The plot allegedly originated in Finland.
The allegations had a negative impact on the popularity of Thaksin and his government, despite the fact that no evidence was ever produced to verify the existence of a plot. Thaksin and his Thai Rak Thai party vehemently denied the accusations and sued the accusers. The leaders of the 2006 military coup claimed Thaksin's alleged disloyalty as one of their rationales for seizing power.
Protests against Thai Prime Minister Thaksin Shinawatra increased throughout 2005 and 2006 due to a variety of factors, including his April 2005 appearance at a merit-making ceremony at the Temple of the Emerald Buddha, the September 2005 cancellation of Sondhi Limthongkul's Muangthai Raisabdah television show, Thaksin's November 2005 plan to give local communities control of public schools, Thaksin's sale of Shin Corporation in January 2006, and Thaksin's alleged role in the March 2006 destruction of the Phra Phrom Erawan shrine.
