Voting underway in key by-elections across three states, one union territory today

KUALA LUMPUR, 6 OCTOBER 2026 —

Byelections in five Indian states and a union territory today test ruling coalitions’ grip amid high stakes for minority support and regional alliances

The polls, spread across three states and a union territory, will determine the political fortunes of ruling coalitions, opposition parties, and regional alliances ahead of broader electoral tests, while also spotlighting minority vote consolidation in Muslim-majority Assam and the fragile survival of Tamil Nadu’s Tamizhaga Vetri Kazhagam (TVK) government.

The elections mark a critical moment for India’s ruling Bharatiya Janata Party (BJP) and its allies, who face challenges in retaining minority support in Assam’s Nagaon Lok Sabha seat and in West Bengal, where the Trinamool Congress (TMC) remains a dominant force. In Tamil Nadu, the TVK-led government, which relies on external support, will test its popularity in two Assembly seats, while the opposition DMK and AIADMK seek to reclaim lost ground.

The bypolls also come amid allegations of administrative bias in West Bengal, where the Election Commission replaced a police officer in Nandigram—a seat vacated by Chief Minister Suvendu Adhikari—following complaints of partisan conduct.

Assam’s Nagaon Lok Sabha bypoll: BJP vs. Congress vs. AIUDF in Muslim-majority stronghold The Nagaon bypoll, where voting runs from 7 a.m. to 5 p.m., is a three-way battle between the BJP, Congress, and the All India United Democratic Front (AIUDF). The seat, a Muslim-majority constituency, is pivotal for the BJP’s expansion in Assam, while the Congress seeks to retain its minority vote base.

The AIUDF, which suffered a drubbing in the April state elections—shrinking from 16 MLAs to just two—is fighting to revive its influence. A total of 15 candidates, including nine independents, are contesting, but the contest is widely seen as a direct clash between the ruling BJP, Congress, and the AIUDF.

The BJP has fielded its candidate in Nagaon as part of its strategy to consolidate Hindu and minority votes, while the Congress, led by Rahul Gandhi, is banking on its traditional support among Muslims and other minority communities. The AIUDF, led by Badruddin Ajmal, is attempting to regain lost ground after its poor performance in the state elections, where it lost key strongholds to the BJP and Congress.

West Bengal: TMC’s internal divisions and BJP’s push in Nandigram and Rejinagar In West Bengal, byelections are being held in two Assembly seats: Nandigram and Rejinagar. The Nandigram seat was vacated by Chief Minister Suvendu Adhikari, who won two seats in the 2026 state elections and chose to relinquish this one.

The bypoll has drawn national attention due to allegations of administrative bias, with the Election Commission replacing the incumbent police officer-in-charge, Ajay Kumar Mishra, just days before polling. The replacement followed complaints from opposition parties, including the BJP and Congress, that Mishra was too close to the ruling TMC.

In Rejinagar, the contest is a five-way battle involving the BJP, Congress, the All Jharkhand United Party (AJUP), and two factions of the TMC—one led by Adhikari and another by former TMC leader Abhishek Banerjee. The BJP is seeking to make inroads in a state where it remains a distant third behind the TMC and Congress, while the TMC’s internal divisions could weaken its position.

Tamil Nadu and Puducherry: TVK’s survival and DMK’s rebound bid In Tamil Nadu, byelections are being held in Madurantakam (SC) and Dharapuram (SC) Assembly seats, both of which were vacated by resignations. The results will be crucial for the TVK-led government, which depends on external support to stay in power.

The contest is a five-cornered fight involving the ruling TVK, opposition DMK, AIADMK, the Left Front, and the Tamil nationalist TVK (a separate entity from the ruling party). Chief Minister C. Vijay Joseph, DMK leader MK Stalin, and AIADMK supremo Edappadi K. Palaniswami have all campaigned aggressively, underscoring the stakes.

In Puducherry’s Thattanchavady Assembly seat, the bypoll is seen as a referendum on the four-month-old NDA government led by Chief Minister N. Rangasamy, whose resignation triggered the election. The contest is a three-way fight between the ruling AINRC-led NDA, Congress, and the DMK. The Congress has fielded E. Vinayagam, who is backed by the Tamizhaga Vetri Kazhagam (TVK) of neighboring Tamil Nadu, adding another layer of regional political maneuvering.

Market and political implications: Minority vote consolidation and coalition stability While these byelections do not directly impact financial markets, their outcomes will shape India’s political landscape ahead of potential broader elections. In Assam, the BJP’s performance in Nagaon could influence its strategy for minority outreach, particularly in states like Uttar Pradesh and Bihar, where Muslim vote consolidation remains a key electoral battleground.

A BJP victory in Nagaon would signal its ability to retain minority support despite rising opposition from the Congress and AIUDF.

In West Bengal, the TMC’s ability to hold Nandigram—despite internal divisions and allegations of administrative bias—will be closely watched as an indicator of its resilience. A loss could embolden the BJP and Congress in their push for a 2026 state election rematch.

Meanwhile, in Tamil Nadu, the TVK’s performance in Madurantakam and Dharapuram will determine whether it can strengthen its legislative position or face further erosion of support, particularly if the DMK or AIADMK makes gains.

The Election Commission’s decision to replace the Nandigram police officer highlights ongoing concerns over electoral fairness, particularly in states where ruling parties are accused of using administrative machinery to influence outcomes. The replacement comes amid broader debates over electoral integrity in India, where opposition parties frequently allege bias in law enforcement and revenue departments ahead of polls.

Outlook: Results on October 9 to shape regional and national political calculus With voting concluding today, all eyes are now on October 9, when results will be declared. In Assam, the Nagaon outcome will be a litmus test for the BJP’s minority strategy, while in West Bengal, the TMC’s ability to retain Nandigram will be a barometer of its internal cohesion.

In Tamil Nadu, the TVK’s survival hinges on its performance in Madurantakam and Dharapuram, with the DMK and AIADMK eager to capitalize on any weaknesses. The Puducherry bypoll, though smaller in scale, will serve as a bellwether for Rangasamy’s NDA government’s early stability.

The bypolls also come as India’s opposition parties, led by the Congress, seek to regroup after a series of electoral setbacks. The Congress’s performance in Assam and Tamil Nadu will be critical in determining whether it can regain momentum ahead of potential state elections in 2027. Meanwhile, the BJP’s ability to expand its minority vote base in Assam could set the tone for its broader electoral strategy in the coming years.

As results unfold on October 9, the political fallout will extend beyond state borders, influencing national alliances and reshaping India’s electoral map ahead of what promises to be a highly contested 2027.
