Thailand is seeking to prosecute ousted Prime Minister Thaksin Shinawatra for graft under a law that allows politicians to be tried in absentia, an official said on Tuesday, months after Thaksin’s sister, Yingluck Shinawatra, was sentenced to jail in her absence. Prime Minister Prayuth Chan-ocha, the army chief who led the coup three years ago, said recently that Thailand would pursue Yingluck through diplomatic channels and police cooperation using Interpol, while confirming that she had fled to Dubai. Prayuth also confirmed that he would maintain the ban on political activity, despite a general election scheduled for next year and growing pressure from political parties to lift it.
