AIADMK-led NDA alliance seat-sharing

Of the 234 Assembly constituencies in the State, the AIADMK will contest in 167 constituencies, while the remaining seats have been allotted to its alliance partners.

The BJP, a key constituent of the AIADMK-led National Democratic Alliance in Tamil Nadu, has been allotted 27 seats, seven more than the number it had contested in 2021.

The Pattali Makkal Katchi (PMK) has been allotted 18 constituencies, five less than what it had contested five years ago. The reduction in the number of seats for the PMK is attributed to the perception that the party no longer enjoys as much strength as it did a few years ago, as former Union Minister Anbumani Ramadoss and his father and PMK founder S. Ramadoss are heading their own factions. Dr. Anbumani’s PMK is part of the NDA.

T.T.V. Dhinakaran’s the Amma Makkal Munnetra Kazhagam (AMMK), a breakaway group of the AIADMK, has got 11 seats. The Tamil Maanila Congress (Moopanar) has been given five seats and will contest on the BJP’s lotus symbol in Oddanchathiram, Erode West, Ranipet, Killiyoor, and Kumbakonam.

The Indiya Jananayaka Katchi (IJK), led by T.R. Paarivendhar, will contest from two constituencies, Pallavaram and Kunnam. Puratchi Bharatham, headed by Poovai Jaganmoorthy, will contest one seat.

In addition, the Tamilaga Makkal Munnetra Kazhagam (TMMK), led by John Pandian, has been allotted the Rajapalayam constituency. The New Justice Party and the Singa Tamilar Munnetra Kazhagam (STMK) have been allotted one seat each.
