Thaksin will not yet be indicted because he had filed a request to postpone his original appointment on Wednesday with proof that he has COVID-19, Prayuth Bejraguna, a spokesperson for the Office of the Attorney General, said at a news conference.

The attorney general's office scheduled a new appointment for Thaksin's indictment on June 18, Prayuth said, adding that Thaksin will also be indicted for violating the Computer Crime Act.

Thaksin had been in self-imposed exile since 2008, but returned to Thailand in August last year to begin serving an eight-year sentence. He was released on parole in February from the hospital in Bangkok where he spent six months serving time for corruption-related offenses.

On his return, he was moved almost immediately from prison to the hospital on grounds of ill health, and about a week after that King Maha Vajiralongkorn reduced his sentence to a single year. Thaksin was granted parole earlier this month because of his age — he is 74 — and ill health, leaving him free for the remainder of his one-year sentence.

After the return, the attorney general's office said it had revived an investigation into whether Thaksin almost nine years ago violated the law against defaming the monarch, a crime punishable by up to 15 years in prison.

Thaksin was originally charged in 2016 with violating the law for remarks he made to journalists when he was in Seoul, South Korea, a year before that, but the investigation could proceed only after he was presented with the charge in person in the hospital in January, officials said. Thaksin had denied the charges and submitted a statement defending himself.

Prosecutor's spokesperson Prayuth said there is enough evidence for the attorney general to indict Thaksin. He said the prosecutors have already prepared their statement and documents to present to the court next month.
