The All India Anna Dravida Munnetra Kazhagam (AIADMK) is grappling with a significant internal crisis following the swift expulsion of senior leader K.A. Sengottaiyan from all party posts. This dramatic move by General Secretary Edappadi Palaniswami came just a day after Sengottaiyan issued an ultimatum on September 5, calling for the reunification of estranged party figures, including V.K. Sasikala, O. Panneerselvam, and T.T.V. Dhinakaran. The fallout has immediately raised questions about the party's stability, particularly in the crucial Kongu region, a traditional AIADMK stronghold, and its broader electoral prospects ahead of the 2026 Assembly elections.

Sengottaiyan, a veteran politician associated with the AIADMK since MGR's era, had advocated for unity to strengthen the party against a formidable DMK alliance. His removal, along with other supporters like former Tiruppur MP Sathyabama, signals a deep rift at the party's core. While AIADMK officials downplay the impact, asserting the General Secretary's decision is final, political observers and local journalists suggest this development could act as a 'silent bomb,' potentially eroding the party's grassroots support and impacting critical vote banks in the Kongu and southern districts.

The current situation presents both risks for the AIADMK and potential opportunities for rival parties, as the party's ability to maintain a united front becomes paramount. The internal turmoil could significantly alter the political calculus in Tamil Nadu, especially given the narrow margins that often decide electoral outcomes.

Key Context

Sengottaiyan's Long Tenure: K.A. Sengottaiyan has been a prominent figure in the AIADMK since its inception under M.G. Ramachandran, making his removal particularly impactful due to his seniority and extensive network.
Call for Unity: On September 5, Sengottaiyan publicly urged the AIADMK leadership to reintegrate expelled leaders, setting a deadline for reconciliation to bolster the party's strength.
Swift Retaliation: General Secretary Edappadi Palaniswami responded decisively on September 6, expelling Sengottaiyan and other key supporters, asserting central authority over dissent.
Broader Factionalism: This event is the latest in a series of internal power struggles that have plagued the AIADMK since the passing of J. Jayalalithaa, with various factions vying for control.
