The country has had three leaders in as many days, following a court’s decision to suspend Paetongtarn Shinawatra.

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.

Thailand's Constitutional Court Tuesday suspended Prime Minister Paetongtarn Shinawatra as it adjudicates an ethics complaint triggered by a leaked phone conversation between her and influential senior Cambodian lawmaker Hun Sen about a smoldering border dispute that had left a Cambodian soldier dead.
