The short answer
Move Forward won the most House seats in Thailand’s 2023 election and assembled a majority coalition, but Pita Limjaroenrat could not secure enough support in the joint House–Senate vote. Pheu Thai formed a different government, and court rulings later cleared Pita in one case while ending Move Forward in another.
Chronology
A timeline of the turning points
The House is dissolved
Prime Minister Prayut Chan-o-cha dissolved the House shortly before its term ended, opening the formal campaign for a 14 May election.
Move Forward wins the largest House bloc
The reform party won 151 of 500 seats, ahead of Pheu Thai on 141, while national turnout reached 75.7 percent.
Eight parties sign a coalition agreement
Pita Limjaroenrat announced an alliance with 313 elected MPs and a common policy memorandum, with Move Forward seeking to lead the government.
Pita falls short in the prime-minister vote
He received 324 votes—311 from MPs and thirteen from senators—below the 375 votes then required in the joint sitting.
Court suspension and blocked renomination
The Constitutional Court suspended Pita from MP duties in the iTV share case, while parliament ruled that its procedure barred a second nomination.
Pheu Thai leaves the eight-party alliance
The second-largest party took responsibility for forming a different coalition after senators and conservative parties rejected a government led by Move Forward.
Parliament selects Srettha Thavisin
The Pheu Thai candidate won the joint vote with support from a coalition that included parties associated with the outgoing military-backed government.
Pita keeps his parliamentary status
The Constitutional Court ruled that iTV was not operating a newspaper or mass-media business when he registered as a candidate.
Court orders an end to the Article 112 campaign
A separate ruling held that Pita and Move Forward’s amendment campaign threatened the constitutional order and ordered them to stop it.
Move Forward is dissolved
The Constitutional Court dissolved the party under the Political Parties Act and imposed ten-year bans on the relevant executives.
Remaining MPs regroup as the People’s Party
Move Forward’s surviving parliamentary organisation moved into a new party led by Natthaphong Ruengpanyawut.
What electoral system produced the 2023 result?
Thailand elected 400 constituency MPs and 100 party-list MPs under a two-ballot system. Move Forward won 112 constituency seats and 39 list seats, giving it 151 of 500. Pheu Thai won 141, Bhumjaithai 71 and Palang Pracharath 40. Turnout reached 75.7 percent, the highest recorded for a Thai House election in the Inter-Parliamentary Union series.
The count made Move Forward the clear first-place party but not a majority government. Pita assembled an eight-party alliance with 313 MPs, comfortably more than half the elected House. Under ordinary parliamentary logic that coalition could govern, but a temporary constitutional rule made the route to the premiership depend on unelected senators as well as MPs.
Why did Move Forward finish first?
Move Forward combined opposition to military influence with proposals on decentralisation, competition, labour rights, conscription, constitutional reform and amendment of Penal Code Article 112. It performed strongly among younger voters and in urban areas, but its victory was not confined to one generation: it won thirty-two of Bangkok’s thirty-three constituency seats and made gains across multiple regions.
The result also built on Future Forward’s 2019 breakthrough and the reform debates widened by the 2020 protest movement. Organisational continuity mattered, yet the party and the protesters were not interchangeable. Move Forward translated some shared demands into an electoral programme while using its own candidates, campaign and parliamentary strategy.
How did the appointed Senate block Pita?
Transitional section 272 of the 2017 Constitution allowed the 250-member Senate selected under the post-coup order to join the House in choosing a prime minister during the first five years of parliament. With vacancies taken into account, Pita needed 375 affirmative votes at the 13 July joint sitting even though his coalition controlled a majority of elected MPs.
Pita received 324 votes: 311 MPs and only thirteen senators supported him. The gap was political rather than a recount dispute. Many senators and parties opposed Move Forward’s Article 112 policy, while reform supporters argued that an appointed chamber had overridden the leading electoral coalition. On 19 July, parliament also rejected Pita’s renomination under a rule against repeating a defeated motion.
How did Pheu Thai form the government?
After Pita’s second nomination was blocked, Pheu Thai left the eight-party alliance and excluded Move Forward from its proposed government. It assembled a broader coalition that included Bhumjaithai, Palang Pracharath and United Thai Nation—parties connected to the outgoing conservative and military-backed administration. Pheu Thai argued that this was the available path to ending the long caretaker period.
On 22 August, the joint sitting selected property executive Srettha Thavisin as prime minister. Thaksin Shinawatra returned to Thailand that same day after years abroad. The result brought Pheu Thai back to executive office but also divided voters who had expected the two largest opposition parties to govern together after their combined election performance.
What happened in Pita’s two court cases?
The cases had different facts and outcomes. In the first, the Election Commission alleged that Pita was disqualified because he held inherited shares in iTV when he registered as a candidate. The Constitutional Court ruled on 24 January 2024 that iTV was not operating a newspaper or mass-media business at the relevant time, so his parliamentary membership did not end.
The second case concerned Move Forward’s campaign to amend Article 112. On 31 January, the court characterised the campaign as an attempt to overthrow the constitutional order with the king as head of state and ordered Pita and the party to stop. Recording that as the court’s legal characterisation is different from presenting it as an uncontested description of the party’s stated reform proposal.
Why was Move Forward dissolved in 2024?
The Election Commission used the January ruling to seek dissolution under the Organic Act on Political Parties. On 7 August, the Constitutional Court dissolved Move Forward and banned eleven current or former executives connected to the Article 112 campaign from political office for ten years. Pita was among those banned even though he had already left the party leadership.
The party’s remaining MPs moved to the People’s Party, preserving a large opposition bloc but losing the dissolved organisation and its banned leaders. The sequence made the 2023 election historically important beyond one government: voters changed the ranking of parties, the appointed Senate prevented the first-place coalition’s candidate from taking office, and litigation later removed the winning party itself.
