The electoral battle for three Legislative Assembly constituencies in Darrang district — 49-Sipajhar, 50-Mangaldai, and 51-Dalgaon — is set for April 9, 2026, with a total of 14 candidates competing for the votes of 7,17,540 registered electors across 907 polling stations.
Among the voters, 10,880 are first-time electors. Young voters aged 20 to 29 form the largest single age group at 29 percent — over 2.08 lakh voters — making them a potentially decisive force across all three seats. The district also has 53 centenarian voters, including one who is above 120 years of age.

The Sipajhar constituency has 2,01,883 voters — 1,03,050 male, 98,829 female, and 4 third-gender electors — and four candidates in the fray.
Sitting BJP MLA Dr Paramananda Rajbongshi, who won the seat in 2021 by a margin of nearly 7,000 votes, faces former three-time legislator Binanda Kumar Saikia of the Congress. SUCI-C's Mun Kumar Deka and Independent candidate Harajyoti Buddha are also contesting.
The Mangaldai constituency is fighting its first election as an unreserved general seat, following delimitation. All six candidates here are new faces, making it an entirely open contest.
The field includes Nilima Devi (BJP), Rijumoni Talukdar (Congress), Azizur Rahman (AIUDF), Harekrishna Deka (TMC), Ajit Acharya (SUCI-C), and Prabin Kumar Deka (Independent). The constituency has 2,00,373 voters — 1,01,161 male, 99,209 female, and 3 third-gender electors.
When the seat was reserved in 2021, Congress candidate Basanta Das had won by around 24,000 votes over the BJP. However, the 2024 Lok Sabha results suggest a significant swing — the BJP polled over 96,000 votes in the area against approximately 58,000 for Congress, pointing to a changed political landscape.
Notably, sitting MLA Basanta Das — who had switched from Congress to the BJP — was denied a ticket by the BJP following the seat's de-reservation and based on internal political calculations.
Dalgaon is the largest assembly constituency in Assam by voter count, with 3,15,284 registered electors — 1,59,641 male, 1,55,633 female, and 10 third-gender voters.
Four candidates are contesting: sitting AIUDF MLA Mazibur Rahman, BJP's Krishna Saha, Raijor Dal's Azizur Rahman — backed by the Congress as part of a pre-poll seat-sharing arrangement — and Independent Aynul Hoque.
The Congress decision not to field its own candidate and instead back the Raijor Dal nominee reportedly triggered dissent within the party, with Aynul Hoque being projected as an Independent by dissident Congress elements.
In 2021, AIUDF's Mazibur Rahman had defeated sitting Congress MLA Ilias Ali by a massive margin of around 55,000 votes. But the 2024 Lok Sabha election told a very different story — Congress polled 2,07,735 votes in the constituency against just 34,055 for the AIUDF-backed BPF candidate, suggesting the tide may have turned.
