is the meeting place of the
National Assembly of Thailand National assembly The
legislative branch (also called the Parliament of Thailand) of the Thai government was first established in the
"temporary" constitution of 1932. The assembly first met on 28 June 1932 in the
Ananda Samakhom Throne Hall. The National Assembly of Thailand is a bicameral legislature featuring a Senate and a House of Representatives. The legislative branch took its current form in 2007. The national assembly has 750 members. Both houses of the national assembly meet at the
Sappaya-Sapasathan.
The House of Representatives The
lower house of the legislative branch has existed in some form since 1932. The House of Representatives is the primary legislative house of the government of Thailand. The House includes 500 members. 400 of the MPs are elected directly from single-seat constituencies around the country. The other 100 members are selected using
proportional representation through
party-lists. This latter set of members is selected from eight electoral areas and 375 constituencies. In this
mixed member majoritarian system, each voter has two votes, one for the constituency MP, and the other for a party in the voter's electoral area. The house is a partisan chamber with seven
political parties. As the primary legislative chamber, the House has more power than the Senate. The House has the power to remove both the prime minister and cabinet ministers through a vote of no confidence. The house sits for a term of four years; however, a
dissolution of the house can happen anytime before the expiration of the term. The house is led by the Speaker of the House of Representatives, who is also the
President of the National Assembly. He is assisted by two deputy speakers. The leader of the largest party or largest coalition party will most likely become prime minister, while the leader of the largest party with no members holding any ministerial positions will become the
leader of the opposition. The leader of the opposition is a powerful position with considerable influence. The leader is assisted by a
shadow cabinet. The last
general election for the house was in 2007. After the 2007 election the
People's Power party (PPP) won the most seats with the
Democrats and
Chart Thai party trailing behind. The composition of the House changed after the
2008 political crisis and the ruling of the constitutional court on 2 December 2008, in which the PPP, the Chart Thai, and the
Neutral Democratic Parties (coalition partners), as well as the prime minister and several party executives were banned from politics for five years. While the successor to the PPP retained most of its seats, its coalition partners defected and joined a Democrat-led government which was inaugurated on 17 December 2008, leaving the
For Thais Party (successor of the PPP) and the
Pracharaj Party in opposition. The House of Representatives and the Senate were abolished after 22 May 2014 coup by the NCPO. Currently, according to the interim Constitution of Thailand imposed by NCPO, there is no House of Representatives. Legislative power is vested in the National Legislative Council, appointed by the NCPO.
The Senate The
upper house of the legislative branch was first established in 1946. However, for most of its history the Senate has been the stronghold of the military and the elite. The current Senate has 150 members. Seventy-six members are elected, one per province from 75
provinces of Thailand (
Bueng Kan does not have an elected senator yet) and one from the
Bangkok Metropolitan Area. The other 74 are selected by the Senate Selection Commission, made up of both elected and appointed officials. The chamber is strictly non-partisan, and members may not be a member of a partisan organisation, the House of Representatives, the judiciary, or the cabinet for five years. The Senate has little legislative power, but retains considerable powers of scrutiny and appointment as the Senate is vested with the power to advise on the appointment of members of the judiciary and independent government agencies. The Senate sits for a set six year non-renewable term and cannot be dissolved. The Senate is presided over by a president of the Senate, who is also the Vice-President of the National Assembly. He is assisted by two vice-presidents of the Senate. The last
election to the Senate was in 2024, The Senate and the House of Representatives were abolished after
22 May 2014 coup by the "
National Council for Peace and Order" (NCPO) government. Following the promulgation of a new constitution in 2017, Thailand held a general election on March 24, 2019, which led to the reinstatement of the House of Representatives. The Senate was also reestablished around the same time, with its initial 250 members being appointed by the National Council for Peace and Order (NCPO) as stipulated by the new constitution's transitional clauses. ==Executive==
