The Election Commission has closed candidate registration for the Sa Kaeo by-election in District 3. Three candidates from different parties are contesting: Sruang from Pheu Thai, Somsak from New Hope, and Srisak from the Economic Party. The former seat-holder party, Klattham, is absent.
On 13 November 2026, the Office of the Election Commission summarized the candidate registrations for the Sa Kaeo Provincial MP by-election in Electoral District 3. This district covers the vacant seat, including Aranyaprathet, Ta Phraya, Khok Sung, and parts of Watthana Nakhon (specifically Chong Kum and Sae O subdistricts). Registration was open from 9 to 13 November 2026 at the second-floor meeting room of Aranyaprathet District Office, Sa Kaeo Province.
Over the five-day registration period (9-13 November 2026), a total of three candidates registered, as follows:
Within seven days after the close of registration (by 20 November 2026), the district election director will publicly announce the list of candidates, including full names, photographs, party affiliations, and candidate numbers used for voting. This information will be displayed at or near polling stations or other appropriate locations.
The Election Commission invites eligible voters to study the candidate information and participate in the Sa Kaeo District 3 by-election to fill the vacant seat on Sunday, 6 December 2026, from 08:00 to 17:00 at their designated polling stations.
Additional reporting indicates this by-election follows the death of former MP Mr. Surasak Chingnavorn of the Klattham Party, who passed away at age 63 on the evening of 24 October 2026, creating the vacancy.
Notably, the Klattham Party has chosen not to field a candidate to defend the seat. The party explained that party leader Lt. Col. Thammanat Prompao and party executives consulted with Mr. Surasak's family and never intended to abstain from contesting. However, due to the short timeframe and lack of a prepared nominee willing to run, they could not submit a candidate in time. This has led to speculation whether this decision opens the way for Pheu Thai. Meanwhile, the People's Party also stated after careful consideration that it will not send a candidate in this by-election.
