Thaksin Shinawatra, who is currently serving a prison sentence, underwent surgery last week and is in recovery, according to his youngest daughter Paetongtarn today (Tuesday).

She declined to disclose any other details, saying she would consult with his doctors who would be the best people to explain the reason for the operation.

Thaksin has been receiving medical treatment at the Police Hospital for almost a month, after being sentenced on three corruption convictions. His eight-year prison time was commuted to one year by HM the King.

Paetongtarn said Thaksin’s blood pressure has been fluctuating on a daily basis.

Asked when her father will be discharged from hospital, she said she does not know. “I am not sure how long he will stay in the hospital, given the fact that he had an operation just last week,” she said.

Thaksin was transferred from the Corrections Hospital, reportedly because of his serious heart problems, which requires heart specialists that the Corrections Hospital do not have.

She admitted that her family wants her father to have the opportunity to recover at home, but there has been no progress on that issue. The family has not yet made an application for parole, she said.
