Yingluck was Thailand's first female prime minister and its youngest in over 60 years. She was removed from office on 7 May 2014 by a Constitutional Court decision!
On 7 May 2014, the Constitutional Court of Thailand removed Yingluck Shinawatra from the office of caretaker prime minister and defence minister following months of political crisis. The court found her guilty of charges of abuse of power over the removal of national security chief Thawil Pliensri in 2011. In the wake of the May 2014 military coup, Yingluck was arrested along with former cabinet ministers and political leaders of all parties and held at an army camp for a few days while the coup was consolidated.
On 22 May 2014, the Royal Thai Armed Forces, led by General Prayut Chan-o-cha, Commander of the Royal Thai Army (RTA), launched a coup d'état, the 12th since the country's first coup in 1932, against the caretaker government of Thailand, following six months of political crisis
