A Bangkok court has acquitted controversial billionaire and former Thai prime minister Thaksin Shinawatra, who was accused of insulting the monarchy, BBC reported.

The lese majeste charge relates to an interview Thaksin gave to a South Korean newspaper ten years ago. He would have faced up to 15 years in jail if convicted.

Thailand's lese majeste law forbids anyone from defaming or threatening the royal family. But critics say lawmakers often use it to target activists and political opponents.

The verdict comes as Thaksin's daughter, suspended PM Paetongtarn Shinawatra, faces a court case that may see her removed from office. The cases have been seen as a big blow to the Shinawatras, who have dominated Thai politics for decades, according to BBC.
