The Pattali Makkal Katchi (PMK), led by Anbumani Ramadoss, has joined the AIADMK-led National Democratic Alliance (NDA) in Tamil Nadu for the upcoming assembly elections. AIADMK General Secretary Edappadi Palaniswami announced the alliance, calling it a "victory alliance" aimed at defeating the ruling DMK government. The PMK's inclusion is seen as consolidating the Vanniyar vote bank. The alliance anticipates more parties joining, with seat allocation details to be announced later. A factional dispute within the PMK between Anbumani Ramadoss and his father, S. Ramadoss, is ongoing.
