Radhapuram — TVK's Sathish Christopher unseats Assembly Speaker M. Appavu
TVK's Dr Sathish Christopher won Radhapuram over the then Assembly Speaker M. Appavu — one of the election's most consequential defeats.
Appavu has been the seat's defining figure for three decades — winning Radhapuram for TMC in 1996, as an Independent in 2001, and for the DMK in 2006 and 2021 — and was elevated to the Speaker's chair in May 2021 at the start of M. K. Stalin's DMK government.
The constituency stretches across Tirunelveli's southwestern coast — fishing villages on the Gulf of Mannar, the Kanyakumari Wind Farm spilling north into the seat, and the Koodankulam Nuclear Power Plant (Russia-built; its first two 1,000 MW units were running in 2026) sitting at the district's southern tip.
The 2016 result here is one of the closest in TN history — AIADMK's I. S. Inbadurai won by just 49 votes over Appavu.

Winners and runners-up, 2006–2026
2011, 2016 and 2021 rows: checked against the ECI detailed results. Earlier rows: secondary sources. Two-part pill: alliance leader first, then the candidate's party.
M. Appavu's career in Radhapuram spans three decades — TMC in 1996, Independent in 2001, DMK 2006, a 49-vote loss in 2016 (one of the closest results in TN history), DMK 2021, and a loss to TVK in 2026 while serving as Tamil Nadu's Assembly Speaker.
In 2011 both leading candidates were junior partners — DMDK in the AIADMK alliance and INC in the DMK alliance. The Speaker's defeat is one of the biggest single-seat results of TN 2026.
About Radhapuram
Radhapuram (AC 228) covers Tirunelveli district's south-western coastal tip, including the fishing villages of the Gulf of Mannar coast, the Kanyakumari Wind Farm corridor (one of the world's largest onshore wind clusters at peak buildout), and the Koodankulam Nuclear Power Plant — a Russia-built (Rosatom) facility whose first 1,000 MW reactor went critical in 2013 and second in 2016, with two more units under construction toward a planned 6,000 MW.
The plant has been the focus of years of anti-nuclear protest. M. Appavu — a four-time MLA from this seat (TMC 1996, Independent 2001, DMK 2006 and 2021, plus a 49-vote loss in 2016) — was elevated to the Tamil Nadu Assembly Speaker's chair in May 2021 under M. K. Stalin's first DMK government.
Radhapuram & the Kanyakumari Coast
Radhapuram is where the subcontinent narrows toward Kanyakumari — a coast lined with fishing harbours, the Muppandal-Aralvaimozhi wind farm spinning off the Aramboly funnel, and the Koodankulam reactors closing the district's southern edge.
Drive 50 km south for Kanyakumari's three-seas confluence and Vivekananda Rock; pull west into the Western Ghats foothills for Tirunelveli's Mundanthurai-Kalakkad tiger reserve, or east along the coast for the centuries-old Manapadu Catholic shrines and the Tiruchendur Murugan temple — closing the southern arc of TN's pilgrim coast.
