Thailand’s opposition parties are making another attempt to strip the junta-appointed Senate of powers to elect the next prime minister before the national vote likely to be held early next year. 

Lawmakers are set to vote late Wednesday on a raft of proposals to amend the 2017 military-backed constitution. A key motion seeks to remove a provision that gives the Senate the power to select the prime minister together with the lower house for the first five years following post-coup elections in 2019.
