AIADMK chief Edappadi K. Palaniswami and senior leader S. P. Velumani are engaged in a leadership struggle within the Tamil Nadu Legislative Assembly.

The rift threatens the stability of the AIADMK as it attempts to navigate a political landscape now dominated by the TVK-led government. This internal conflict follows a poor performance by the party in the state elections held April 23, 2026.

During a post-election assembly session in late April 2026, Palaniswami said he still controls the party and continues to call the shots [1]. However, Velumani has backed Chief Minister C. Joseph Vijay and the TVK government [2]. This open defiance suggests a significant fracture in party discipline and a challenge to Palaniswami's authority.

The tension stems from the fallout of the April elections, which saw a high level of civic engagement. Voter turnout was reported at 85.15 percent [3], though an alternative report placed the figure at 84.69 percent [4]. The resulting victory for the TVK has left the AIADMK searching for a new strategic direction.

Some members of the legislative assembly have expressed a desire to shift their support toward the TVK leader [2]. This movement has led to calls for Palaniswami to quit his position as party chief [2]. The struggle for control is now playing out in the public sphere, with leaders disagreeing on who should steer the party forward in the wake of the electoral debacle [1].

As the TVK-led government begins its tenure, the AIADMK remains divided between those loyal to Palaniswami and those who believe a leadership change is necessary to survive the current political climate [1, 2].

AIADMK chief Edappadi K. Palaniswami said he still controls the party.

The leadership clash within the AIADMK signals a potential permanent fracture in one of Tamil Nadu's traditional political pillars. By aligning with the TVK-led government, dissidents like Velumani are attempting to secure political relevance in a new era of governance, while Palaniswami's struggle to maintain control highlights the difficulty of holding a party together after a significant electoral defeat.
