BANGKOK (AFP) – Thailand has revoked the passports of ousted premier Yingluck Shinawatra, who has yet to be seen in public since she slipped out of the country before the verdict in her negligence trial, officials said yesterday. The former prime minister has not been seen or heard from since she stunned the kingdom by failing to turn up for the Supreme Court verdict in late August. She was later sentenced to five years in prison in absentia for failing to stop graft in a government rice. “All of Yingluck’s passports have been revoked now,” Foreign Minister Don Pramudwinai said yesterday. Yingluck had four Thai passports, two personal and two diplomatic, according to authorities.
