89 senators strongly condemned Natthapong for labeling the Senate as the "Blue Senate," a legacy of the coup, demanding an apology within 3 days and threatening legal action.
On 25 May 2026, a group of 89 senators led by Mr. Phisit Apiwatnapong, Mr. Sombun Noonual, Mr. Chaiyong Maneerungsakul, and Mr. Alongkot Woraki held a press conference condemning opposition leader Natthapong Ruangpanyawut for posting accusations that the Senate is the "Blue Senate" and attacking it as a legacy from the 2017 constitution imposed after the coup referendum.
Mr. Phisit affirmed that these allegations are untrue and constitute malicious behavior aimed at undermining the Senate’s credibility. He demanded Natthapong issue a public apology within 3 days, warning that failure to comply would result in immediate legal action. He challenged Natthapong to clarify what "blue regime" refers to, noting that for the Senate, blue is the color on the national tricolor flag representing the duty to protect the monarchy.
Mr. Phisit further stated that Natthapong’s attacks on the Senate stem from frustration over his inability to form a government in the recent election, leading him to incite and slander the Senate without evidence, despite this Senate being legitimately elected and under independent oversight.
Regarding the constitutional amendment under Article 256, he affirmed that Natthapong’s position does not affect the Senate’s decision, as they remain committed to serving the nation’s interests. He questioned whether the People’s Party is genuinely sincere about constitutional reform, noting their history of attacking the Senate, despite the law requiring one-third Senate approval. Additionally, the Senate firmly opposed the Pheu Thai Party’s proposal to reduce the Senate’s voting threshold to one-quarter, insisting on maintaining the one-third requirement and prohibiting amendments to chapters 1, 2, and any articles related to royal powers.
