Thaksin entered politics in late 1994 through Chamlong Srimuang, who had just reclaimed the position of Palang Dharma Party (PDP) leader from Boonchu Rojanastien. In a subsequent purge of Boonchu-affiliated PDP Cabinet ministers, Thaksin was appointed Foreign Minister in December 1994, replacing Prasong Soonsiri. Thaksin left Palang Dharma along with many of its MPs in 1996, and founded the populist Thai Rak Thai (TRT) party in 1998. After a historic election victory in 2001, he became prime minister, the country's first to serve a full term. Thaksin introduced a range of policies to alleviate rural poverty; highly popular, they helped reduce poverty by half in four years. He launched the country's first universal Health care program, the 30-baht scheme, as well as a highly notorious drug suppression campaign. Thaksin embarked on a massive program of infrastructure investment, including roads, public transit, and Suvarnabhumi Airport. Nevertheless, public sector debt fell from 57% of GDP in January 2001 to 41% in September 2006. Levels of corruption were perceived to have fallen, with Transparency International's Corruption Perceptions Index improving from 3.2 to 3.8 between 2001 and 2005. The Thai Rak Thai party won an unprecedented landslide in the 2005 general election, which had the highest voter turnout in Thai history. Twelve years later, after Thaksin was removed from power, Chamlong Srimuang expressed regret at getting "such a corrupt person" into politics. The PDP soon withdrew from the government over the Sor Por Kor 4-01 land reform corruption scandal, causing the government of Chuan Leekpai to collapse.
