Born in Chiang Mai province, Yingluck Shinawatra earned bachelor's degree from Chiang Mai University and master's degree from Kentucky State University, both in public administration.[4] She became an executive in the businesses founded by her elder brother, Thaksin Shinawatra, and later became the president of property developer SC Asset and managing director of Advanced Info Service. Meanwhile, her brother Thaksin became Prime Minister, was overthrown in a military coup, and went into self-imposed exile after a tribunal convicted him of abuse of power.
In May 2011, the Pheu Thai Party, which maintains close ties to Thaksin, nominated Yingluck as their candidate for Prime Minister in the 2011 general election.[5][6] She campaigned on a platform of national reconciliation, poverty eradication, and corporate income tax reduction, but the ruling Democrat Party claimed that she would act in the interests of her exiled brother. The Pheu Thai Party won a landslide victory, winning 265 seats in the 500 seat House of Representatives of Thailand,[7] It was only the second time in Thai political history that a single party won a parliamentary majority, the first party was her brother's party, Thai Rak Thai.
