Udhayanidhi Stalin retained his Chepauk-Thiruvallikeni Assembly constituency on May 4, 2026, defeating D. Selvam by a margin of 7,140 votes, a noteworthy achievement amid a significant defeat for the DMK as his father, M.K. Stalin, lost his own seat in the same election.
In this election cycle, Udhayanidhi secured his second consecutive win in the constituency; however, the lead he achieved this time was markedly narrower than the previous election in 2021, where he won by an impressive margin of 69,355 votes. The results indicate a shift in voter sentiment that could have implications for the future of the DMK.
As the numbers unfolded on election day, documents show that the DMK’s seat share plummeted from 133 seats to just 6 by 5 PM. In contrast, the Tamil Vazhvu Katchi (TVK) emerged as a significant player in these elections, winning 10 seats and leading in an additional 99.
Udhayanidhi is widely seen as the political heir of both Karunanidhi and M.K. Stalin—his victory may position him as a potential leader of opposition if DMK ends up being recognized as the main opposition party in Tamil Nadu’s political landscape.
Observers noted that Udhayanidhi’s lead was particularly contentious; he narrowly led by just 1,048 votes after round eight of counting. The Chepauk-Thiruvallikeni seat has traditionally been a DMK stronghold, adding weight to the significance of this electoral outcome.
The results reflect broader trends within Tamil Nadu politics and raise questions about the future direction of the DMK under its current leadership. As political analysts continue to dissect these developments, Udhayanidhi’s role may become increasingly pivotal as he navigates this altered political terrain.
