Former Thai Prime Minister Yingluck Shinawatra has fled to Dubai, senior members of her party said Saturday, a day after she failed to show up for a negligence ruling in which she faced up to 10 years in prison.

Sources in her Puea Thai party said the former prime minister left Thailand last week and flew via Singapore to Dubai where her brother, Thaksin Shinawatra, also a former prime minister, lives in self-imposed exile to avoid a 2008 jail sentence for corruption, has a home.

"We heard that she went to Cambodia and then Singapore from where she flew to Dubai. She has arrived safely and is there now," said a senior member of Puea Thai, who declined to be named because he was not authorized to speak to the media.
