V.S. Babu of the Tamilaga Vettri Kazhagam (TVK) won the Kolathur assembly seat, defeating incumbent Chief Minister M.K. Stalin (DMK) on Monday [1].
The defeat represents a significant political blow to the DMK chief, as he lost a traditional stronghold in Chennai during the 2026 Tamil Nadu Legislative Assembly elections [2].
According to India Today, V.S. Babu secured 52,996 votes [3], while M.K. Stalin received 44,541 votes [3]. This result marks a major shift in the constituency's political landscape, a region where the incumbent had previously maintained a strong grip on power [4].
Reports on the exact winning margin vary slightly among sources. Moneycontrol and the Financial Express reported a victory margin of 8,795 votes [5, 6]. However, calculations based on the vote totals provided by India Today suggest a margin of 8,455 votes [3]. Earlier interim counts indicated that Stalin was trailing by more than 8,000 votes as the process unfolded [7].
The victory for the TVK candidate is part of a broader trend in the 2026 state elections where the TVK made significant gains across the region [2]. The loss of the Kolathur seat is seen as a setback for the DMK leadership, specifically for the Chief Minister who faced a direct challenge in his own backyard [2].
Babu's win in the Chennai-based constituency signals a changing appetite among the electorate. The TVK's ability to unseat a high-profile leader like Stalin suggests a successful mobilization of voters against the established DMK machinery [2, 8].
“V.S. Babu of the Tamilaga Vettri Kazhagam (TVK) won the Kolathur assembly seat, defeating incumbent Chief Minister M.K. Stalin.”
The defeat of a sitting Chief Minister in his own constituency is a rare and high-impact event in Indian state politics. It indicates not only a localized rejection of the DMK's performance in Kolathur but also the emergence of the Tamilaga Vettri Kazhagam as a potent electoral force capable of dismantling established political strongholds in Tamil Nadu.
