The wife of Thailand's former PM Thaksin Shinawatra has been sentenced to three years in jail for tax fraud.
Pojaman Shinawatra was granted bail by a Bangkok court in the first of several cases against the former first family, reported BBC.
Her brother and secretary were also found guilty of evading tax of 546m baht ($16.3m) in a 1997 shares transfer in the family telecoms business.
The ex-PM himself, deposed in a 2006 coup, is being tried in the Supreme Court for alleged corruption.
Pojaman Shinawatra's brother, Bannapot Damapong, was also sentenced to three years, while her secretary was handed a two-year sentence.
The trio were freed on bail of 5m baht ($149,000) each on Thursday, pending an appeal.
Mr Thaksin's wife, who is his most important political and business partner, looked stunned as the court delivered its verdict.
Seconds after the ruling, she reportedly walked over to pat her husband on the back.
Mr Thaksin's spokesman, Pongthep Thepkanjana, said the family would appeal and "fight to the end".
A judge read out the verdicts in a televised ruling, saying that she should have been "a good role model as the wife of the prime minister".
