The AIADMK has faced an internal organisational dispute in Viluppuram following the 2026 Assembly election, with disagreements emerging over the party’s district-level leadership. Viluppuram has traditionally been an important political stronghold for the party in northern Tamil Nadu, making developments within the district organisation significant for its future political strategy.
The dispute involved former district secretary C. Ve. Shanmugam and the party leadership under Edappadi K. Palaniswami. Following organisational changes, R. Pasupathi was appointed as the new Viluppuram district AIADMK secretary. The developments have highlighted differences within the party and raised questions about how the AIADMK will reorganise its grassroots structure following the 2026 election.
