In the 2011 general election, the pro-Thaksin Pheu Thai Party again won a decisive victory over the Democrat Party, and Thaksin's youngest sister, Yingluck Shinawatra, succeeded Abhisit as prime minister. Elected in July, the Pheu Thai Party-led government began its administration in late-August, and when Yingluck entered office, the 2011 Thailand floods threatened the country—from 25 July 2011 to 16 January 2012, flood waters covered 65 of the country's 76 provinces. The World Bank assessed the total damage in December 2011 and reported a cost of THB1.425 trillion (about US$45.7 billion).
