Electoral system

As in the 2023 election, the electoral system followed that of the 2021 amendment of the 2017 constitution. The 500 members of the House of Representatives were elected by parallel voting. 400 seats were 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.

The 100 party-list seats were distributed under the "100 divisor" formula, restored in 2022 after parliament failed to finalise a rival draft within its 180-day deadline. The national party-list vote is divided by 100 to give a quota; each party takes one seat for every whole quota it has won, and the seats still unfilled go to the parties with the largest fractional remainders. List seats are awarded on top of constituency seats rather than in compensation for them, so a party that sweeps the constituencies keeps its full proportional entitlement as well. Writing shortly before the system was first used, Napon Jatusripitak of the ISEAS–Yusof Ishak Institute observed that cutting the number of list seats from 150 to 100 raised the share of the vote needed to win one and allowed larger parties to take a higher proportion of seats than of votes.
