Thai voters have voted in favour of a new constitution, paving the way to replacing the junta-backed 2017 Constitution.

According to the Vote62 election watch platform, which pulls its vote count data from the Election Commssion of Thailand (ECT), 19,885,709 people or 65.4% have voted in favour of a new constitution as of 12.25 on 9 February when 93% of votes have been counted. Meanwhile, 10,503,475 (34.6%) voted against.

2,879,773 people, or 9.6%, came to the poll but checked the abstain from voting box.

Vote62’s visualization shows that the majority voted in favour in the northern and central provinces. Meanwhile, in the northeast, most provinces voted in favour, with the exception of some constituencies in Buriram, the hometown of Bhumjaithai Party’s founder Newin Chidchob and where Bhumjaithai won all 10 constituency seats.

In Buriram’s 3^rd constituency, 28,354 (46.7%) voted in favour and 32,422 (53.3%) voted against. In its 10^th constituency, where 27,341 (48.7%) voted in favour and 28,776 (51.3%0 voted against.

In the south, against votes were concentrated in Chumphon, Ranong, Surat Thani, Phang Nga, Nakhon Si Thammarat, Trang, and Patthalung. In Krabi, two constituencies voted against, while one voted in favour. In Prachuab Kiri Khan, one constituency voted in favour and another voted against.

In-favour votes won by small margins in 4 of Songkhla’s 9 constituencies, including in Hat Yai, one of Southern Thailand’s largest cities, and in Chana and Thepa districts, where there are strong community rights movements against megaprojects which poses environmental concerns.

Meanwhile, most in-favour votes in the south were concentrated in Yala, Pattani, and Narathiwas – the three Deep South provinces – a region gripped by an ongoing conflict and where citizens have spent decades under martial law.

The referendum is only the first step of constitutional reform. Parliament will now have to amend Section 256 of the Constitution and set up the process for selecting members of the drafting committee. The amendment will then need to be approved in another referendum before the drafting process can begin.

On 10 December 2025, parliament began debating in its second reading a bill proposing amendments to the 2017 Constitution concerning the amendment process and the formation of a constitutional drafting committee. The bill was returned to parliament from an ad hoc committee after two bills, proposed by Bhumjaithai and the People’s Party, passed in their first readings in October 2025.

However, on 11 December 2025, a joint sitting of MPs and senators voted to reject a proposal that future constitutional amendments be approved by a simple majority in the joint sitting, opting instead to revert to requiring support from at least one-third of senators. It has been noted that several Bhumjaithai MPs join the vote to reject the committee’s proposal.

The main opposition People’s Party called for a new vote by roll call as there were less than 30 votes between for and against and prepared to file a no-confidence motion against the government of Anutin Charnvirakul. The bill was subsequently withdrawn and the House of Representatives was dissolved the next morning.

In what later turned out to be the House’s final motion before its dissolution, parliament voted 494 to 1 to adopt a motion submit the questions for the first constitutional amendment referendum to the Cabinet, requesting that the referendum be initiated.
