Thailand’s new Cabinet members have taken their oaths of office, including the suspended prime minister who is under an ethics investigation.

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.
