Why it matters
This byelection is a significant test of political influence in a key urban constituency and reflects the competitive nature of regional Indian politics.
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.
Long considered a personal stronghold of Mr. Rangasamy, who won the seat four times consecutively, starting in 1991 before returning to win it again in 2021, the constituency remains sought-after in Puducherry’s political landscape.
