2023 Thai general election

General elections are expected to be held in Thailand no later than 2023.

Electoral system

The election will be the second to take place under the 2017 constitution drafted under the National Council for Peace and Order (NCPO—the military junta in power from 2014 to 2019). The 500 members of the House of Representatives are elected using a form of mixed-member proportional representation, in which voters cast a single vote. 350 seats are elected from single-member constituencies by first-past-the-post voting, with the remaining 150 being levelling seats, allocated to ensure parties receive a number of seats proportionate to their national vote total. As in the preceding 2019 election, the parliament's vote for Prime Minister will take place in a joint session with the 250-seat senate, according to the constitution's provisional terms. As the term of the NCPO-appointed senate lasts until 2024, it is expected to exert influence into this election as well.
