"Some people may want to demonstrate publicly to show their unhappiness about how Yingluck is being treated," he said. Ms Shinawatra's Puea Thai Party has said it does not support acts of violence and urged supporters to gather peacefully. Some supporters outside the court in Bangkok held roses while others wore white gloves with the word "love" on them. The court is due to rule in the separate case on Friday of Ms Yingluck's former commerce minister Boonsong Teriyapirom who is accused of falsifying government-to-government rice deals between Thailand and China in 2013. The Shinawatra family's parties have won every general election since 2001, but it is at the heart of a bitter and bloody power struggle in Thailand. Ms Yingluck's brother, former prime minister Thaksin Shinawatra, was ousted in a 2006 coup. Supporters of the Shinawatras accuse the ruling generals of political persecution.
