Do we like them?Do we like Natthaphong Ruengpanyawut?
Our score: 7 out of 10. A decent reformer with no harmful words or company found, held back by thin evidence of his own voice on LGBTQ+ and climate issues and two live legal fights.
Natthaphong, nicknamed Teng, is the fourth son of a property developer. He studied computer engineering at Chulalongkorn University, then founded a cloud software firm before politics. Future Forward founder Thanathorn handed him the party's online platform, and in 2019 he narrowly won the Bangkok seat of Bang Khae.
His career has been a lesson in Thai party-hopping by force. Future Forward was dissolved by a court in 2020, so he moved to Move Forward, which was dissolved in 2024. He was then picked to lead the People's Party on 9 August 2024 and, at 37, became the youngest Leader of the Opposition in Thai history.
The big legal cloud is the ethics case. He is among 44 current and former MPs who signed a 2021 proposal to amend Section 112, the royal insult law, and the National Anti-Corruption Commission was reported to be weighing allegations of serious ethical breaches. The Supreme Court accepted the case in April 2026 but didn't suspend the ten sitting MPs involved. If found guilty, he could face a lifetime ban from office, and he has argued independent agencies shouldn't be used to destroy political opponents. Where you land depends on whether you see it as a legitimate law-reform bid or an ethics breach.
He is also accused of criminal defamation by Gulf Energy Development over remarks at an October 2024 press conference criticising government energy procurement and electricity costs. Gulf is seeking 100 million baht in compensation. He pleaded not guilty in February 2026 and says he acted in good faith as an MP to protect the public interest. Witness hearings were set for October, and we couldn't find a result.
On the harm check, we found no slurs, conspiracy theories or culture-war grifting from him, and no dodgy company. His party said in May 2026 it will draft laws on tax, surrogacy and nationality to match marriage equality, and it has pledged to push on regardless of the government. We didn't find a statement from Natthaphong himself on trans rights or climate, and that is the gap: the pass rests on his party's record and the absence of anything harmful, not on a ringing quote.
The People's Party lost the 8 February 2026 election to Bhumjaithai, and he took it on the chin. He said the party was beaten on strategy and weak grassroots work, and that he wouldn't resign: “My duty now is to keep the party moving forward as steadily as possible.” He has since been formally appointed Leader of the Opposition.
