Profile of Chaiyanachai Dechadecho, Deputy Leader of the Democrat Party overseeing the southern region, recently accused by a prominent page of involvement in a drug trafficking network. He has denied the allegations and is preparing to sue those who defamed him, noting the political motives during the election period.
On 21 Jan 2026 GMT+7, the news resurfaced when the CSI LA page posted: “Urgent: Police preparing to search the home of the ‘Deputy Leader of the Democrat Party’ from the south, initials ‘T.’, linked to a drug trafficking network.” Many suspected Chaiyanachai Dechadecho, Deputy Leader for the southern region. Recently, Chaiyanachai clarified, firmly denying any acquaintance with Jakkrit Dechadecho, aka Sun or “Sun Thungjeen,” who was arrested on drug charges. He explained that sharing the Dechadecho surname does not imply relation, as many in Nakhon Si Thammarat share it. In fact, his parents’ original surname is a Chinese clan name, but his father adopted the Dechadecho surname with the approval of a respected senior police officer and has used it since. When asked if leaked photos could make defense difficult, Chaiyanachai said as a politician, being photographed is normal and urged fairness, asking why the Dechadecho surname is being used to attack him and the Democrat Party now during an election when the party is regaining strength in the south.
“If anyone has financial records or communication evidence linking me to involvement, please present it publicly or submit it to the investigators. I welcome scrutiny. But if these are baseless accusations aimed solely at political gain during the election, I reserve the right to pursue full legal action to protect my reputation and the truth,” Chaiyanachai stated.
Chaiyanachai was born on 14 June 1986, nicknamed “Tan.” He is the eldest son of Mr. Withoon and Mrs. Kanokporn Dechadecho, Chair of the Nakhon Si Thammarat Women's Development Committee and former President of the Nakhon Si Thammarat Provincial Administrative Organization. He has three younger brothers: Phichitchai Dechadecho, Phithakdech Dechadecho—an MP for Nakhon Si Thammarat and Deputy Spokesperson for the Democrat Party—and Phongdech Dechadecho.
Chaiyanachai is married to Ms. Chadalak Worapong (Tukta); they have three children. His wife is listed as a partner in Triple T 2017 Limited Partnership and serves as secretary to the Commerce and Intellectual Property Committee, appointed on 26 Oct 2023 GMT+7. In 2023, the couple declared assets totaling 173,592,108 baht with liabilities of 69,042,388 baht.
Chaiyanachai completed secondary education at Benchamarachuthit School in Nakhon Si Thammarat, earned a Bachelor of Arts in Political Science and a Master of Arts in the same field from Ramkhamhaeng University, and completed the National Defense Course for Future Executives at the National Defense College (Class 1), alongside Ms. Paethongtarn Shinawatra, former Prime Minister.
In the cabinet reshuffle of Paethongtarn 2, Chaiyanachai Dechadecho, Deputy Leader of the Democrat Party and two-term MP for Nakhon Si Thammarat, was named a new ministerial appointee as Deputy Minister of Public Health, following advocacy by then Democrat Party Leader Chalermchai Sri-on and MP Det Ism Khaothong, the party secretary-general.
Additionally, Chaiyanachai was reported to the National Anti-Corruption Commission by Mr. Chao Meekhuad, a lawyer and former Deputy Spokesperson of the Democrat Party, alongside Ms. Aranya Chantadee, legal counsel for victim Mr. Naret Wongsathakul. They requested investigation into allegations of serious ethical violations related to an incident on 23 May 2025 GMT+7, where Chaiyanachai allegedly assaulted a local businessman during a monk ordination ceremony and attempted to pressure the victim to withdraw the complaint.
Most recently, he has been in the spotlight again due to police arresting drug dealer Jakkrit Dechadecho, aka Sun or “Sun Thungjeen,” who shares the surname. Chaiyanachai denied knowing him and is preparing to file defamation charges against the page that posted the allegations.
