DMK candidates Sukanya and Paranthaman formally filed their nomination papers on Tuesday, 15 September 2026 for the October 6 Assembly by-elections in Dharapuram and Madurantakam constituencies in Tamil Nadu, as campaign activity across both seats shifted into higher gear. The filings mark a significant escalation in what is shaping up as a multi-party electoral contest with implications for the state's political balance.
Nomination Day: What Happened on the Ground
In Dharapuram, candidate Sukanya submitted her papers to Returning Officer Felix Raj. DMK deputy general secretary M.P. Saminathan, former minister Kayalvizhi Selvaraj, and district secretary L. Padmanabhan were among the senior party figures accompanying her during the filing.
In Madurantakam, candidate Paranthaman arrived at the Revenue Divisional Office flanked by a sizeable contingent of party functionaries and supporters. Former minister T.M. Anbarasan and other senior DMK office-bearers were also present, signalling the party's intent to treat both seats as priority contests.
Why These By-Elections Are Being Held
The vacancies arose after AIADMK legislators representing both constituencies resigned from the Assembly and joined Chief Minister C. Joseph Vijay's Tamilaga Vettri Kazhagam (TVK). K. Maragatham Kumaravel, who had held the Madurantakam seat, and P. Sathyabama, the Dharapuram legislator, crossed over to the ruling party after winning their seats as AIADMK candidates in the 2026 Assembly election, leaving both constituencies vacant.
A Multi-Cornered Contest Takes Shape
The Dharapuram bypoll is shaping up as a particularly intense battle. Sathyabama is contesting under the TVK banner — facing voters just months after winning the same seat on an AIADMK ticket. Bhanumathi has been fielded by the AIADMK, while Karthika will represent the Naam Tamilar Katchi. The Communist Party of India was expected to name its candidate on Tuesday, potentially setting the stage for a five-way contest in the reserved constituency.
On the ground, party workers across both seats have begun organising public meetings, door-to-door canvassing, and booth-level mobilisation ahead of polling day.
What Each Party Is Fighting For
The stakes differ sharply for each contender. The TVK is seeking to demonstrate that the defections from the AIADMK carry genuine popular backing. The AIADMK, which has described both Dharapuram and Madurantakam as traditional strongholds, is attempting to reclaim constituencies it won only months ago. The DMK, for its part, is looking to exploit the split in opposition votes and strengthen its Assembly presence.
Notably, the results of these two seats could set the tone for momentum ahead of future state-level electoral contests.
Key Dates
Polling in both constituencies is scheduled for October 6, 2026, with votes to be counted on October 9, 2026. Nominations and campaign strategies across all parties are being closely tracked by political observers as an early indicator of how the new party alignments are playing out at the grassroots level.
Point of View
Fighting to reclaim seats it won barely months ago, has the clearest moral case, but also the steepest hill to climb in a state where the ruling party's patronage machine is formidable. The DMK's best hope is an opposition vote split — which, given the five-way field in Dharapuram, is not implausible. What mainstream coverage understates is that the outcome will also test the organisational depth of the newly formed TVK outside its founder's direct appeal.
