Former Minister Denies Jet Misuse Amid Asset Declaration Probe

A senior Thai politician, Suriya Juangroongruangkit is facing scrutiny after a complaint was filed with the National Anti-Corruption Commission (NACC) alleging that a private jet was declared at a value far below its market price, raising questions over asset disclosure and potential legal consequences. The case has drawn public attention due to the high value of the aircraft and claims circulating on social media about its alleged misuse.

On 6 February 2026, at 9.00am, Srisuwan Janya, leader of the Rak Chart Rak Phaendin organisation, submitted a petition asking the NACC to investigate whether a prime ministerial candidate from a major political party deliberately filed a false assets and liabilities statement. The individual concerned previously served as deputy prime minister and a senior minister in the government of Paetongtarn Shinawatra, and filed the declaration upon leaving office on 24 September 2025.

The complaint follows claims posted by the CSI LA Facebook page, which alleged that a senior Thai politician identified as “Big S” purchased a Gulfstream G550 private jet from a foreign financier described as “grey capital”. The post claimed the aircraft’s true value was about 800 million baht, paid in monthly instalments of 100 million baht, but declared to the NACC at only 30 million baht. It also alleged the jet bore the initials “SRJ” and was used to transport ammunition to persons in northern and northeastern Thailand.

Later in response to the claims, Mr Kritchanont Aiyapanya, Pheu Thai Party deputy spokesperson issued a statement defending Suriya Juangroongruangkit, the accused. He said the Gulfstream G550 had a total value of 862,191,500 baht and was legally imported, with value-added tax paid to the Customs Department on 13 September 2024. He stated that Mr Suriya declared a 30-million-baht share because that was his ownership portion, with the remaining value held by relatives and said the asset declaration to the NACC was complete and accurate.

Mr Kritchanont rejected claims that the aircraft was used to transport ammunition, calling them “entirely false” and a distortion of facts. He said Mr Suriya last used the jet in early November last year and urged the public to verify information from reliable sources.

According to the petition, the NACC filing dated 17 November 2025 lists the jet as acquired on 12 September 2024 and valued at 30 million baht. Market checks cited by the complainant state that a new Gulfstream G550 costs about 2 billion baht, while used aircraft typically sell from about 600 million baht upwards. Srisuwan cited Section 114 of the 2018 Organic Act on Anti-Corruption, under which intentionally submitting false asset information is an offence, with penalties under Section 167 including up to five years’ imprisonment, a fine of up to 100,000 baht, or both, and possible political disqualification for up to 10 years.

Naewna reported that the NACC is now being asked to investigate the case, determine whether the declaration was false, and, if so, refer the matter to the Supreme Court’s Criminal Division for Political Office Holders.

Key Takeaways
