BANGKOK — Thai politics faces another seismic shift as former Prime Minister Paetongtarn Shinawatra announced her resignation as Pheu Thai Party leader Wednesday morning.
In a public letter to party members and the general public, she explained her decision to step down:
“Today, I have decided to resign from the position of Leader of the Pheu Thai Party, with the intention that this marks the beginning of an overhaul of the Pheu Thai Party, as I announced on October 7, 2025. This is with a new vision, courageous in change, for the people in the truest sense.
Currently, we are in an era where global society is fragile, complex, sensitive, and difficult to predict. Thailand is at the most critical transitional phase with the upcoming election. Therefore, the Pheu Thai Party, as the country’s main political party, needs to overhaul, transform, change its structure, process, and entire way of thinking so that the party can win the election and then proceed to overhaul and revitalize Thailand.
I firmly believe that the change for the Pheu Thai Party must start as soon as possible. Thus, I have chosen to resign from the position of party leader to allow the party the freedom to conduct this overhaul and build a new, perfect party.”
While Paetongtarn framed her resignation as part of the party’s transformation strategy announced on October 7, the timing follows the Constitutional Court’s August 29 ruling that removed her from the prime ministership for ethics violations related to a leaked audio conversation with Cambodian Senate President Hun Sen.
Though not specified in party regulations, her legal status could complicate future candidate endorsements, as party leaders must sign off on parliamentary candidates. “If a petition is filed, our candidates might not be able to register,” a source explained, describing the move as “a preemptive measure to prevent future damage to the party.”
Anutin Signals Early Dissolution
The timing coincides with Prime Minister Anutin Charnvirakul’s hint that parliament could dissolve before January 31, 2026, stating “anything can happen.”
The Bhumjaithai Party leader’s confidence stems from decisive by-election victories over Pheu Thai in Kanchanaburi’s District 4 on October 19 and earlier in Si Sa Ket’s District 5 on September 28. Combined with Anutin’s strategic reshuffling of 45 Interior Ministry officials—he serves as Interior Minister—these wins signal Bhumjaithai’s potential rise from third-largest party to frontrunner.
Anutin emphasized that dissolution timing remains his prerogative, with no obligation to inform media in advance.
The Red-Blue Breaking Point
The coalition rupture intensified when Paetongtarn’s government backed investigations into Senate selection irregularities, which allegedly favored “Blue Senators” allied with Bhumjaithai. Simultaneously, her administration pursued land encroachment cases in Buriram’s Khao Kradong forest, involving the influential Chidchob family—key Bhumjaithai supporters—despite Supreme Court rulings that the disputed land belongs to the State Railway of Thailand.
The Shinawatra Squeeze
Before either case concluded, the Thai-Cambodian border conflict erupted. Hun Sen’s release of Paetongtarn’s negotiation audio on June 18—despite its focus on war avoidance—led to her removal as PM for “seriously violating ethical standards” and damaging Thailand’s dignity, according to the Constitutional Court on August 29.
Days later, on September 8, former PM Thaksin Shinawatra received a one-year prison sentence, restarting his term count. The father-daughter duo’s setbacks prompted coalition partners and former supporters to abandon Pheu Thai for Anutin’s camp.
Orange Party Sets Terms
Despite Bhumjaithai’s seat count falling short of 100, Anutin secured a deal with the People’s Party, the leading opposition force. Under a memorandum of agreement, the Orange Party demands Anutin form a minority government within four months and initiate constitutional amendments before dissolving parliament for fresh elections.
Since becoming PM, Anutin has attracted numerous prominent MPs from various parties, including some from Pheu Thai itself, giving the Blue Party advantages across the board.
Abhisit Returns: Blue-Democrat Alliance Solidifies
On October 18, Democrat Party members elected former PM Abhisit Vejjajiva as leader with 96.18 percent support. Anutin congratulated Abhisit the next day at a football match celebrating 170 years of Thai-UK diplomatic relations—continuing rapport established during a September dinner meeting before Abhisit’s leadership bid.
This camaraderie evokes memories of 2008, when Newin Chidchob’s faction (precursor to Bhumjaithai) defected from the Red camp to support Democrat Abhisit as PM through barracks negotiations. That alliance sparked massive Red Shirt protests, culminating in military crackdowns in 2010 that left 99 dead during Abhisit’s government.
While Democrats and Bhumjaithai will compete in southern constituencies, analysts expect the leaders’ friendship to translate into continued support for an Anutin-led government.
Pheu Thai Without Shinawatra
Pheu Thai has announced internal restructuring to address weaknesses and strengthen policy implementation capabilities. Despite the previous coalition government’s incomplete policy agenda, the party is preparing to campaign on finishing unfinished business while unveiling new parliamentary candidates.
The interim Party Executive Committee meeting on October 22 selected Chusak Sirinil to serve as acting party leader until the election of a new party leader and a new Party Executive Committee at the Pheu Thai Party’s extraordinary general meeting on October 31.
Paetongtart’s resignation follows her declaration that Pheu Thai’s next PM candidates will not come from the Shinawatra family—marking a historic transformation for both the party and Thai politics.
During Pheu Thai Party’s second round of parliamentary candidate unveiling on October 17, which Paetongtarn did not attend, Suriya Juangroongruangkit presided over the event in his capacity as the party’s Election Director.
Given Suriya’s prominent role within the party—having previously served as Deputy Prime Minister and Transport Minister, along with his ability to coordinate both internal and external party affairs—he is widely expected to become the next Pheu Thai Party leader. However, he later declined, revealing that the new party leader will be someone within the party but not from the Shinawatra family.
