Trouble appears to be mounting for All India Anna Dravida Munnetra Kazhagam (AIADMK) general secretary Edappadi K Palaniswami, with a section of influential party leaders stepping up efforts to challenge his leadership after the party’s disappointing performance in the Tamil Nadu Assembly elections.
The brewing revolt has now moved beyond closed-door criticism and entered the organisational arena, with dissident leaders exploring party rules to trigger a larger confrontation within the AIADMK leadership structure. Senior leaders aligned with the rebel camp believe the electoral setback has weakened EPS politically and opened the door for a leadership reset inside the party.
According to party sources, the dissident faction led by former ministers CV Shanmugam and SP Velumani is examining provisions within the AIADMK constitution that allow members to demand a special general council meeting. Under party rules, the general secretary is required to convene such a meeting within 30 days if one-fifth of the council members formally seek it.
IANS mentioned sources as saying that leaders supporting the rebellion have already started reaching out to general council members across Tamil Nadu to gather signatures required for the move.
The rebel camp has reportedly been holding regular strategy meetings from Shanmugam’s office in Chennai’s MRC Nagar. Discussions are centred around building pressure on Palaniswami and preparing for a possible organisational battle in the coming weeks.
Leaders backing the rebellion have accused EPS of making unilateral decisions that, according to them, weakened the AIADMK politically and contributed to its poor electoral showing.
The AIADMK suffered one of its worst defeats in recent memory in the 2026 Assembly elections. The party managed to win only 47 seats and slipped to the third position in the Assembly, losing the Leader of the Opposition status for the first time in decades.
Several senior functionaries within the party are privately describing the outcome as the AIADMK’s weakest performance since the 1996 elections.
Why AIADMK rebels want leadership change
Leaders in the dissident camp argue that Tamil Nadu politics is rapidly shifting towards a younger political generation. They point to the rise of Chief Minister C Joseph Vijay, Deputy Chief Minister Udhayanidhi Stalin, PMK president Anbumani Ramadoss, BJP state president K Annamalai and Naam Tamilar Katchi chief Seeman as evidence of changing political dynamics in the state.
According to them, the AIADMK risks losing further ground unless it adapts to the changing political landscape with a new leadership approach.
The rebels are also believed to be upset over EPS refusing to step aside from his chief ministerial ambitions during earlier political discussions involving a possible broader opposition alignment. Party insiders claim there had been conversations around projecting VCK leader Thol Thirumavalavan as a consensus chief ministerial face with external support from the DMK.
Rebel MLAs may join Vijay Cabinet
The internal crisis has also taken a wider political turn, with speculation growing that some rebel AIADMK MLAs could be inducted into Chief Minister Vijay’s Cabinet next week.
The development comes while a petition filed by EPS seeking the disqualification of rebel legislators under the anti-defection law is still pending before Assembly Speaker JCD Prabhakar.
One rebel leader defended the group’s recent decision to support the TVK government during the trust vote, arguing that remaining in the Opposition for another five years would neither help the public nor revive the party politically.
The developments have triggered fresh uncertainty within the AIADMK at a time when the party is already struggling to recover from its worst electoral setback in decades.
