What a by-election is, why seats fall vacant, and what the October 2026 trends in Nandigram, Nagaon and Tamil Nadu mean
A bypoll (by-election) is an election held to fill a single legislative seat that becomes vacant between general elections. In India, the Election Commission of India (ECI) conducts bypolls for Lok Sabha and state Assembly seats.
| Seat | State / UT | Type |
|---|---|---|
| Nandigram | West Bengal | Assembly |
| Rejinagar | West Bengal | Assembly |
| Madurantakam | Tamil Nadu | Assembly |
| Dharapuram | Tamil Nadu | Assembly |
| Thattanchavady | Puducherry | Assembly |
| Nagaon | Assam | Lok Sabha |
Polling was held on October 6, 2026, and counting began on October 9, 2026.
These are trends, not final results:
Turnout was high, at about 76% to 84% across the seats.
What is the difference between a bypoll and a general election? A bypoll fills one or a few vacant seats, while a general election renews the full house.
How long does the winner serve? The remainder of the original term of that seat.
Who can contest? Any eligible candidate, whether from a party or independent, subject to nomination rules.
Are trends the final result? No. Trends are early indications and can change until the final round.
