The suspension order capped two tumultuous weeks in Thai politics, triggered by the leak of the call between Hun Sen and Paetongtarn, in which she appears to pander to the Cambodian strongman and then denigrate a Thai military commander.

Chaikasem, who turns 77 in August, has extensive government experience: a former attorney general, he served as Minister of Justice under former Prime Minister Yingluck Shinwatra—Thaksin’s sister and Paetongtarn’s aunt—until that government was overthrown in 2014.

Paetongtarn Shinawatra, Thailand’s youngest prime minister and scion to the country’s most prominent political dynasty, may lose power barely a year after taking the top political office.
