Prime Minister of Thailand sixteen out of twenty-nine, including the incumbent General Prayut Chan-o-cha. Military dominance began with the country's second Prime Minister, Phot Phahonyothin, who ousted his civilian predecessor in a coup in 1933. The longest serving Prime Minister was Field Marshal Plaek Pibulsonggram at 14 years, 11 months and 18 days. The shortest was Tawee Boonyaket at just 18 days. Nine were removed by coups d'état, three were disqualified by court order, and eleven resigned from office. The youngest ever to occupy office was M.R. Seni Pramoj at 40 years old. Thailand received its first female prime minister, Yingluck Shinawatra, in 2011.
2006 Thai coup d'état replied: "I will." This contradicted earlier public statements where he denied that the military would stage a coup. "The Nation" noted that the timing of the coup contains many instances of the number nine, a highly auspicious number in Thai [[numerology]]. The coup occurred at the 19th day of the 9th month of [[Buddhist Era]] 2549. Coup leader Sonthi Boonyaratglin made a major public announcement on the morning after the coup at 9.39 am. "The Nation" earlier indicated 09:16 as the time for Sonthi's press conference and the [[Buddhist calendar]] is in line with the [[Gregorian calendar]] only since 1941.
