The next general elections are scheduled to be held in Thailand no later than 27 June 2027. They will determine the composition of the House of Representatives.
This will be the third election under the 2017 constitution, which was implemented under the National Council for Peace and Order (the junta that took power in the 2014 Thai coup d'état), and the first after the expiration of the constitution's five-year transitory provision that gave the senate voting rights to choose the prime minister in a joint session of parliament. As such, unlike in 2023 when the junta-appointed senate (whose term also ends after five years) blocked the election's majority winner from forming government, this time the outcome of the election should determine the resulting government.[1]
As in the 2023 election, the electoral system will follow that of the 2021 amendment of the 2017 constitution. The 500 members of the House of Representatives are elected by parallel voting. 400 seats are elected from single-member constituencies by first-past-the-post voting and 100 seats by proportional representation. Voters cast separate ballots for the two sets of seats.[2]
