Thailand former Prime Minister Yingluck Shinawatra has been denied permission to travel overseas, the BBC news reported.
A spokesman for the military-backed government said the move was designed to make sure she was in the country to face criminal charges later this month.
She is accused of corruption in a scheme she oversaw to subsidise rice farmers which could result in a 10-year jail term. She denies the charges.
She was also banned from politics following her impeachment in January.
The former prime minister had asked for permission to leave the country until 22 February, government spokesman Sunsern Kaewkumnerd said.
He added that the attorney general was due to submit a subpoena on 19 February and she would have to be present for the case to go ahead.
Yingluck's lawyer said it was not necessary for her to appear in court for at least two months and if the military government used her case as an excuse to deny her the right to travel, that would be a "violation of her basic rights".
