The Rot Within: Thailand’s Interior Ministry In Focus

A series of recent scandals within the Ministry likely reflect tensions within the leadership of the ruling Bhumjaithai party.

To many, suggestions for bureaucratic reform in Thailand are hollow slogans rather than viable policy undertakings. It is one thing to restructure government agencies, as Thailand is doing in real time by splitting its Tourism and Sports Ministry to merge tourism functions with the Culture Ministry. It is another thing entirely to tackle corruption and patronage networks, which has not been done in the eyes of the public. Worse still, a series of developments last month surrounding the Interior Ministry, the centralized body overseeing local administration and internal security, put alarming tendencies on display.

The first problem arose in mid-June at the level of the provincial leadership appointed by the Interior Ministry. Word spread online that the governor of Phuket, following his crackdown on illegal beach businesses operated under the protection of influential officials, was threatened with being booted out by one of his own deputies.

While the alleged source of discord is a familiar one in Phuket, a tourism and development powerhouse defined by varied and competing interests, the province’s growing notoriety as a hub for foreign nominee businesses, coupled with the publicized flaunting of powerful backing by a certain high-ranking member of the public service to bypass formal structures, prompted Prime Minister Anutin Charnvirakul to intervene directly in his concurrent capacity as Interior Minister. He swiftly approved the reshuffle of Phuket’s two deputy governors, Teerapong Chuaychu and Adul Chuthong, to the same positions in Nakhon Si Thammarat and Songkhla provinces, respectively. The accompanying expectation was that Nirat Pongsitthaworn, governor of Phuket since November 2025, would carry on with his duties. Yet he, too, was subsequently transferred to Bangkok as deputy permanent secretary of the Ministry.

As much as the sweeping turnover was probably intended to create a clean slate and improve governance efficiency, the narrowing of the space to pursue self-interest is what matters most. Besides, it is only when the public thinks the disputing parties are subject to unbiased treatment that there is an appreciation for leadership turnover. Because Nirat had already been deputy permanent secretary from 2020 to 2022, his reassignment to the same role naturally struck observers as a demotion, regardless of it being technically equivalent in rank to that of the governor. That Nirat’s former deputies found themselves in populous administrative centers hardly considered a “downgrade” further fed into the premise that whoever leverages stronger backing prevails in Thailand’s bureaucratic system.

The second problem centering around aspiring bureaucrats exploded in late June. Thailand’s Central Investigation Bureau uncovered an illicit network helping applicants cheat their way through the entry-level local government examinations in an exceptionally sophisticated manner, employing a hybridized method to alter physical answer sheets and manipulate digital records.

The scale was likewise unprecedented. In 2025, there were 6,669 vacancies under the Interior Ministry’s Department of Local Administration. Out of over 400,000........
