Seenivasa Sethupathy of the Tamilaga Vettri Kazhagam (TVK) won the Tiruppattur Assembly seat by one vote [1].

The result marks a rare instance of a one-vote margin in a high-stakes legislative race, resulting in the defeat of a sitting minister. This outcome highlights the extreme volatility of the current electoral climate in the Sivaganga district of Tamil Nadu.

Sethupathy received 83,375 votes [2], while KR Periyakaruppan of the Dravida Munnetra Kazhagam (DMK) received 83,374 votes [2]. The narrow victory of one vote [1] handed the seat to the TVK candidate and displaced the DMK heavyweight from his position in the Tiruppattur Assembly constituency [2].

Reports indicate the impact of individual voter turnout on the final tally. One voter traveled from Oman to cast a ballot for the TVK candidate. Following the announcement of the results, that voter was told, "You saved our day" [3].

The victory in Tiruppattur is part of a broader surge for the TVK. The party now holds 108 seats in the Tamil Nadu Assembly following the election [4].

Sethupathy's win over Periyakaruppan represents a significant shift in local power dynamics, specifically the ability of a new political force to dismantle the hold of established party ministers through razor-thin margins.

The one-vote victory in Tiruppattur underscores the diminishing dominance of established political heavyweights in Tamil Nadu. By securing 108 seats, the TVK has transitioned from a challenger to a major legislative power, proving that even small shifts in voter turnout—such as a single overseas citizen returning to vote—can fundamentally alter the composition of the state government.
