By Drooid · · How we work
Core Event
On October 6 2026 voters in six constituencies—Nandigram and Rejinagar (West Bengal), Madurantakam and Dharapuram (Tamil Nadu), Thattanchavady (Puducherry) and the Nagaon Lok Sabha seat (Assam)—will cast ballots to fill seats vacated after the April 2026 elections. Counting is set for October 9 2026.
Background & Context
- West Bengal: The BJP formed a government in May 2026, ending the Trinamool Congress’s 15-year rule. Chief Minister Suvendu Adhikari retained Bhabanipur, triggering a by-poll in Nandigram. Rejinagar became vacant after Aam Janata Unnayan Party founder Humayun Kabir kept the Nowda seat.
- Tamil Nadu: The Tamilaga Vetri Kazhagam (TVK) led a four-month-old government after the April 2026 Assembly election. Two AIADMK MLAs—K Maragatham Kumaravel and P Sathyabama—resigned and joined TVK, prompting by-polls.
- Puducherry: Chief Minister N. Rangasamy (AINRC) retained Mangalam, leaving Thattanchavady vacant.
- Assam: Congress MP Pradyut Bordoloi switched to the BJP and won the Dispur Assembly seat, vacating Nagaon.
Data & Statistics
- Candidates: Nandigram 16; Rejinagar 21; Madurantakam ? 30; Dharapuram 30; Thattanchavady 11; Nagaon 15 (9 independents).
- Electorates: Madurantakam 212,639 voters, 268 stations; Dharapuram 222,406 voters, 282 stations; Thattanchavady 26,921 voters.
- Security: West Bengal deployed 34 companies of central forces and 819 state police to guard 315 polling stations.

Why It Matters
- BJP: First electoral test after assuming power; seeks to gauge Muslim voter response in Nandigram (?30 % minority) and Rejinagar (?70 % minority).
- TVK: Views the Tamil Nadu seats as a referendum on its ability to convert personal popularity into a durable mandate.
- Opposition: Provides a platform for Trinamool, Congress, AIADMK, DMK and regional parties to assess coalition prospects.
- Assam: The BJP aims to turn a high-profile party-switch into a parliamentary win; AIUDF’s participation raises vote-splitting concerns.
