A brewing ideological rift has emerged within the People's Party (PP) as core supporters criticise the appointment of Surapon Nitikraipot, sparking debate over the party's direction.
The controversy erupted after the party inroduced the management team for the Bangkok gubernatorial campaign of Chaiwat Sathawornwichit, appointing the former Thammasat University rector as chairman of its strategic advisory board.
What was intended to highlight a team of experienced professionals instead triggered a backlash from supporters and progressive allies, exposing divisions within the party's ranks.
At the centre of the dispute is Prof Surapon's past. Critics have pointed to his role in the National Legislative Assembly established after the 2006 military coup and his participation in anti-government protests linked to the People's Democratic Reform Committee.
For many supporters, those actions conflict with the democratic values associated with the party and its predecessor movements.
Party secretary-general Phicharn Chaowapatanawong acknowledged supporters' concerns. He said lasting political change could not be achieved without persuading former opponents to join the democratic camp.
Mr Phicharn said the party had long believed expanding support beyond its core voter base was essential to securing meaningful political, economic and social reforms.
He argued Prof Surapon had evolved politically, recognising the damage caused by coups and undemocratic power structures, and had spent recent years supporting democratic causes and younger generations.
He cited Prof Surapon's legal opinion defending the former Move Forward Party during its dissolution case as evidence of his commitment to democratic principles.
Mr Phicharn also rejected claims the appointment was intended to rehabilitate controversial political figures, describing it instead as an effort to reduce political divisions and broaden alliances.
PP leader Natthaphong Ruengpanyawut offered a similar defence, saying the party remained committed to democracy while welcoming individuals who shared its goals. He described Prof Surapon as a respected legal scholar with expertise in public law and governance.
