Gummidipoondi 27,945-vote flip — TVK takes the Andhra-border seat back

TVK's S. Vijayakumar won Gummidipoondi by 27,945 votes over AIADMK's V. Sudhakar — a sharp reversal in a seat the DMK's T. J. Govindarajan had carried by 50,938 votes only five years earlier. Gummidipoondi has been a four-way battleground since the 2000s: AIADMK's K. S. Vijayakumar squeaked through by 229 votes in 2006, DMDK's C. H. Sekar swept it by 29,256 in 2011, and AIADMK reclaimed it in 2016 before DMK's 2021 surge. The 2026 result hands the constituency — a chemicals-and-logistics belt straddling the Chennai-Tirupati highway — to TVK in its first contest.

About Gummidipoondi

Gummidipoondi — AC 1 — is the northernmost assembly seat in Tamil Nadu, sitting in Thiruvallur district along NH-16 about 50 km north of Chennai and a short drive from the Andhra Pradesh border. The constituency wraps around the Gummidipoondi SIPCOT industrial estate — a sprawling chemicals, auto-component and steel cluster set up in 1984 — and the Pulicat Lake fringe. Beyond the factory belt, the seat covers paddy villages, the Arani river basin, and the Kalahasti-bound pilgrimage road that brings Telugu-speaking traffic through the constituency every weekend.

Pulicat lake and the SIPCOT belt

Lagoon flamingos, a Dutch cemetery and the road to Kalahasti

Gummidipoondi is the gateway between Chennai and the Pulicat lagoon — India's second-largest brackish lake, where flamingos winter in thousands and Dutch tombstones from the 1600s still stand at the old cemetery in Pulicat town. Drive past the SIPCOT chimneys to Arani river crossings, the Amirthi forest fringe, or push 90 km north to Sri Kalahasti's Vayu-lingam temple in Andhra.
