Thaksin had requested a postponement of his indictment due to a COVID-19 diagnosis, but the new appointment is now scheduled for June 18.

Thaksin returned to Thailand last year to serve an eight-year sentence for corruption-related offenses and was released on parole in February.

Thaksin Shinawatra, the former prime minister of Thailand, was released from prison early due to ill health and age (74).

His sentence was reduced to one year, granting him parole.

His return was seen as a political deal between his Pheu Thai Party and the conservative establishment to prevent the progressive Move Forward Party from forming a government after winning the general election last year.

Upon his release, the attorney general's office announced the revival of an investigation into Thaksin for alleged monarchy defamation, which could result in up to 15 years in prison.

Thaksin, a former prime minister of Thailand, was charged in 2016 for violating the law with comments he made to journalists in Seoul, South Korea, in 2015.

The investigation could not proceed until he was presented with the charge in person in the hospital in January.

Thaksin denied the charges and submitted a defense statement.

Prosecutors have enough evidence for the attorney general to indict Thaksin, and they plan to present their statement and documents to the court next month.

Thaksin has been influential in the current government led by Prime Minister Srettha Thavisin, which has reportedly angered ultra-conservatives, leading to the indictment.

Thitinan Pongsudhirak, a professor at Chulalongkorn University in Bangkok, explained that the ongoing legal case against former Prime Minister Thaksin is being used to control his actions.

If Thaksin misbehaves, the charge could result in his imprisonment, limiting his movement and reminding him of who is in charge.
