 Taiwan ceased to be a single-party state in 1986 under President Chiang Ching-kuo, Chiang Kai-shek's son, and political reforms beginning in the 1990s under President Lee Teng-hui loosened the KMT's grip on power.Nevertheless, the KMT remains one of Taiwan's main political parties, with Ma Ying-jeou, elected in 2008 and re-elected in 2012, being the seventh KMT member to hold the office of the presidency.In the 2016 general and presidential election, the KMT was defeated in both elections and the Democratic Progressive Party (DPP) gained control of both the Legislative Yuan and the presidency, Tsai Ing-wen being elected President.
