Puducherry's Thattanchavady Assembly constituency is bracing for a multi-cornered byelection scheduled for October 6, 2026, with the Congress, DMK, AINRC, and CPI entering the bypoll fray.

The Thattanchavady Assembly constituency, a prominent urban segment under the Oulgaret Municipality, has become the centre of the spotlight, as Chief Minister and AINRC founder N. Rangasamy chose to vacate the seat after retaining the second seat of the Mangalam constituency, which he won in the April 2026 Assembly polls.

Thattanchavady: key facts

A general constituency, Thattanchavady has 26,921 voters, including 14,341 women, 12,575 men, and five third-gender voters. In the Union Territory with small electorate, the electoral outcome is often more related to the personal rapport of the candidate with the electors, though all major political parties have their committed voter base.

Beyond the ongoing grapple for power, Thattanchavady is confined by its long-standing regional and infrastructure issues. The lack of job opportunities and failure to open more units within the local Thattanchavady Industrial estates have been a primary concern. The constituency is also facing an everyday infrastructure deficit, with traffic congestion and the issue of stray dogs having been common subjects of discussion during all election seasons.
