Nattapong accepted the results of the Nonthaburi Provincial Administrative Organization election, stating plans to file a complaint with the National Anti-Corruption Commission against the Election Commission regarding the Senate case by no later than this Friday. He revealed that the schedule for the government's no-confidence debate is set for October to November.
On 21 September 2026, Nattapong commented on the Nonthaburi PAO election results, where the Prachachon Party candidate was defeated despite holding all eight parliamentary seats in the area. He said that they must accept the outcome as it stands. Comparing percentages relative to voter turnout, the gap has narrowed. He was reluctant to attribute it to any single factor, noting there are likely multiple causes, but the clear figure is the reduced voter turnout among all eligible voters.
Prachachon Party Secretary-General Pichorn Chaowaphatwong said that reviewing elections since 2023, including the Progressive Party and the general election in February 2026, the party's raw vote share and popularity have not declined but actually increased. Regarding the Nonthaburi PAO election, he acknowledged that voter turnout was lower compared to 2025: 41% then versus 35% on 20 September. The drop is significant and may be due to the public being unaware that the election was taking place.
Plans to file a complaint with the National Anti-Corruption Commission against the Election Commission by Friday.
Nattapong also updated on the Senate rigging case timeline, saying the Prachachon Party is pursuing legal action against the Election Commission and related individuals suspected of misconduct or abuse of power. The party’s legal team completed a complaint for submission to the National Anti-Corruption Commission last week but has been refining it with new facts and evidence that emerged. He confirmed they are ready to file it immediately, likely within this week, and barring further developments, no later than Friday. He will personally submit the complaint to the National Anti-Corruption Commission.
Revealed that the schedule for the government no-confidence debate is locked in for October to November.
When asked about progress on filing a no-confidence motion against the government, Nattapong said he has coordinated with other opposition coalition parties. He confirmed the motion will be presented during the current parliamentary session, expected between October and early November, though details remain limited. Asked whether the Senate rigging issue would be a main focus or part of the debate, he said Parliamentary Speaker Sophon Sarum has publicly stated there is no attempt to block the Senate corruption topic from being discussed. He hopes the speaker maintains this principle, as debating the conduct and qualifications of government officials, whether inside or outside the current administration, is valid grounds for a no-confidence debate.
