Some parts of the Government of Thailand are selected through democratic elections. These include the House of Representatives of Thailand, (which combines with the appointed Senate of Thailand to create the National Assembly of Thailand), local Administrations, Governorship of Bangkok and national referendums. Thailand has so far had 28 general elections since 1933; the last election was in 2023. Voting in elections in Thailand is compulsory. All elections in Thailand are regulated by the Election Commission of Thailand. Elections are held under universal suffrage in accordance with the 2007 Constitution; however, certain restrictions apply: The voter must be a national of Thailand; if not by birth, then by being a citizen for 5 years. They must be over 18 years old the year before the year the election is held. The voter must have also registered ninety days before the election at his constituency. Those barred from voting in House elections are: members of the sangha or clergy, those suspended from the privilege (for various reasons), detainees under legal or court orders, and people of unsound mind or of mental infirmity. Regarding universal suffrage, Thailand (and Siam) has given women right to vote in national election since 1932, and in village election since 1897, which could make Thailand the second country in the world to do so. The House of Representatives consists of 500 members, of which 350 are directly elected through the first past the post system in which each member represents one "constituency". The other 150 is elected through party lists given to the election commission by the political parties before election day. In the current system as laid out by the 2017 constitution, known as "mixed member apportionment (MMA)", the voter casts a single vote for a constituency MP, which is then also used in the calculation of the party list seats. This differs from the previous 2007 constitution, where the vote for constituency MP and party list MP were separate.
