On 8 February, Thai citizens will vote to elect members of the House of Representatives, the lower house of the National Assembly, following its dissolution in December 2025. 500 seats are up for election, with 400 chosen by constituency and the remaining 100 allocated to political parties in proportion to their nationwide vote share. 251 parliamentary votes are required to elect a prime minister, which is typically achieved through post-election coalition negotiations between multiple parties. The election must be certified within 60 days, by 9 April, and the parliament must convene within 15 days of election results being confirmed.
A referendum is also scheduled for the same day to determine whether to replace the current constitution, which was only enacted in 2017. Thailand’s Constitutional Court ruled in September 2025 that drafting a new constitution requires three referendums. The first would approve the initiation of the drafting process; the second would focus on the draft’s key principles and approach; the third would constitute final approval of the draft.
57 parties have registered to take part in the election, but three main parties will be the primary contenders: the ruling conservative Bhumjaithai Party (BJT), the progressive reformist People’s Party (PP), and the populist Pheu Thai Party (PTP). Incumbent Prime Minister Anutin Charnvirakul is representing BJT. PP and PTP are the third incarnations of previous parties dissolved by the Thai courts for legal or technical breaches.
Southern Insurgency Likely to Escalate During Thai Election Period
Thailand’s current constitution was adopted in 2017 following a political crisis, which led to the removal of Yingluck Shinawatra in a military coup in 2014. As it was drafted under a military junta, the current constitution was approved in a tightly controlled referendum and is viewed as granting excessive power to the Senate, which has the authority to approve the prime minister and members of numerous independent bodies, including the Thai Constitutional Court. Many Thais view the constitution as imposed rather than chosen and have demanded reforms.
The election is taking place amid a broader political crisis. The border dispute with Cambodia, which led to direct fighting in July and December 2025, triggered the expulsion of former Prime Minister Paetongtarn Shinawatra (niece of Yingluck and daughter of former prime minister Thaksin Shinawatra, both members of PTP or one of its predecessors) after she expressed deference to the Cambodian former leader Hun Sen and criticised the Thai military in a leaked phone call.
Her successor, Anutin Charnvirakul, who took power in September, has faced heavy criticism over his minority government’s handling of the flooding in southern Thailand in November, which left at least 176 people dead. Adding to this was PP’s pulling of support from the BJP and its looming vote of no confidence over its alleged failure to honour promises to reform the constitution, compelling Anutin to dissolve parliament and call a general election in December.
A coalition government is the expected outcome of the election, with no party likely to win an outright majority. According to recent polling by Suan Dusit, respondents to a 28 January poll backed BJP by 21.14 per cent, PP by 21.11 per cent, and PTP by 17.56 per cent. 23.85 per cent of respondents were “still undecided”, suggesting that there could be a large disparity in electoral results from the polling. In a 6-9 January poll, PP leader Natthaphong Ruengpanyawut was the top choice for prime minister for 31.99 per cent, with PTP leader Yodchanan Wongsawat second on 17.45 per cent, and the incumbent Anutin third on 15.14 per cent. However, BJP’s polling has likely been inflated by a surge in nationalism linked to the ongoing Thailand-Cambodia border dispute and could diminish in the lead-up to the election, should the current ceasefire continue to hold.
Despite its popularity in the polls, PP faces potential legal action from the National Anti-Corruption Commission (NACC) that could bar dozens of its members from running for attempting to amend Article 112 of the Criminal Code, Thailand’s royal insult (lèse-majesté) law, in 2021. The amendment sought to reduce penalties, narrow who could file complaints, and limit what constitutes an offence. While procedurally lawful within parliament, the proposal was later characterised by opponents as an abuse of office and an act undermining the constitutional order.
In the 2023 election, PP’s progenitor party, Move Forward, which openly campaigned on amending Article 112, won 151 seats in parliament, the most votes of any party, but was blocked from power by lawmakers tied to the royalist military due to its support for the amendment. Its prime ministerial candidate, Pita Limjaroenrat, was subsequently suspended from parliament and later barred from politics after Thailand’s Constitutional Court ruled that his candidacy violated electoral law, effectively preventing him from assuming office.
Since then, PP has moderated its position during this electoral campaign, dropping the call to change Article 112 and softening its stance on the military, which it previously wanted to drive out of politics. Even so, PP’s historical backing of the amendment almost certainly exposes the party to political pressure and, in extremis, potential bans from candidacy.
Should PP receive the most votes but be barred from candidacy, widespread protests are highly likely, as was observed in 2023. These would highly likely be led by the Thai youth, who make up a large part of the reformist parties’ support base. Previous bouts of major unrest mixed with institutional paralysis have triggered coups from Thailand’s powerful military on numerous occasions. This is unlikely to occur again in the short-term due to independent mechanisms typically now being preferred tools for managing political crises in Thailand in an effort to increase democratic legitimacy. However, if protests become widespread, violent, and sustained, with a political deadlock over the election winner, this would highly likely increase the risk of a coup.
Large-scale unrest is not the only potential physical risk likely to increase in Thailand during the electoral campaign. Thailand has been experiencing an ongoing separatist insurgency since 2004 in the southern provinces of Pattani, Yala, Narathiwat, and parts of Songkhla. Insurgents have traditionally increased attacks during electoral cycles to undermine the central government and achieve maximum publicity for their cause. In 2023, insurgents set fire to cell phone towers and tyres across Yala, Pattani, and Narathiwat provinces. During the election periods in 2011 and 2014, insurgent activity increased around polling and campaigning phases, marked by attacks on infrastructure, local officials, and security forces.
On 11 January 2026, a series of coordinated bomb and arson attacks targeted PTT petrol stations across Thailand’s Deep South, injuring at least four. A member of the largest insurgent group, Barisan Revolusi Nasional (BRN), has since declared that the group is “likely to conduct attacks like arson, shootings and bombings to remind political parties of their demands” around the general election. Further attacks in the run-up to the election are likely, with incidents likely to be contained to the southern border provinces of Pattani, Yala, Narathiwat, and parts of Songkhla, and designed to generate publicity and exert political pressure, rather than cause mass casualties. However, attacks on Thai Buddhists, state officials, military personnel, police officers, and local Muslims perceived as cooperating with the authorities have increased in recent years, and there is a realistic possibility that more hardline elements of the insurgency will conduct more deadly attacks during the electoral period.
