BANGKOK — Buoyed by an election boycott called by Thailand's main opposition party, the head of the country's anti-government protest movement vowed Sunday to hound caretaker Prime Minister Yingluck Shinawatra “until she is dead or until she leaves” office. Addressing supporters after a day of rallies and marches all over Bangkok involving more than 100,000 people, Suthep Thaugsuban issued a series of threats to try to achieve his group's goal of forcing Yingluck to step down and make way for a non-elected interim government before a snap election she has called for Feb. 2. The main opposition Democrat Party announced Saturday that it would boycott the polls. Suthep's so-called People's Democratic Reform Committee says forcing Yingluck from office is necessary to purge corruption and money politics. “Because Yingluck clings to her prime minister's seat, we must come out to chase her,” Suthep told supporters Sunday night. “We will keep chasing her until she is dead or until she leaves.” A group of protesters demonstrated briefly outside Yingluck's Bangkok home earlier Sunday, but she was not home. She has spent recent days in Thailand's north and northeast, her political strongholds. — AP
