Sidli-Chirang covers the town of Sidli along with a large number of surrounding villages. It has a predominantly rural character with a large number of villages under its coverage and remains dominated by tribal communities, typical of the Bodoland Territorial Region in Lower Assam.
Being a new constituency, Sidli-Chirang had no Assembly electoral history and voted for the first time in its new identity in the 2026 assembly elections. It participated, though, in the 2024 Lok Sabha elections, where the UPPL led against the BPF by a margin of 7,529 votes. UPPL polled 75,317 votes, while BPF polled 67,788 votes, with the Congress in distant third place.
The predecessor Sidli (ST) constituency had participated in 15 assembly elections, including one by-election in 2024, during its existence between 1951 and 2023. Congress won 5 elections in 1951, 1962, 1967, 1972, and 1983. The Plain Tribals Council of Assam secured two wins in 1978 and 1985. Independent candidates won the seat on four occasions, in 1991, 1996, 2001, and 2006. Recently, the Bodoland People’s Front (BPF) candidate Chandan Brahma won consecutive elections in 2011 and 2016, after winning the election in 2006 as an independent. In 2021, the UPPL candidate Joyanta Basumatary defeated the BPF candidate Chandan Brahma by a margin of 31,320 votes. Basumatary polled 97,087 votes, while Brahma polled 65,767 votes. In 2024, however, Joyanta Basumatary vacated the seat when he contested and won the Kokrajhar Lok Sabha seat on a UPPL ticket. In the resultant 2024 by-election, the UPPL candidate Nirmal Kumar Brahma defeated the BPF candidate Suddho Kumar Basumatary by a comfortable margin of 37,016 votes, securing 95,243 votes, while Basumatary polled 58,227 votes.
In the Sidli segment of the Kokrajhar Lok Sabha constituency, the trend entirely favoured independent candidates, with an independent candidate leading by a margin of 2,225 votes in 2009 against BPF, then again leading in 2014, against another independent candidate, by a margin of 3,733 votes, with BPF in third place, far behind both. In 2019, an independent candidate led again, by a margin of 5,630 votes over the UPPL, while the BPF finished third. In the 2024 election, UPPL managed to lead against the BPF by a margin of 7,529 votes. The UPPL candidate polled 75,317 votes, while the BPF candidate received 67,788 votes, with Congress placed distant third.
Sidli-Chirang seat had 219,623 eligible voters on the final roll for the 2026 Assembly elections, witnessing a rise from 213,378 registered voters in the 2024 parliamentary elections and 217,813 registered voters in the 2024 by-election. Voter turnout was high at 83.79 in the 2024 parliamentary election and 73.96 in the 2024 by-election.
Demographics, based on available data largely from the 2011 Census proportions adjusted for the area and delimitation changes, indicate a strong Scheduled Tribe majority (predominantly Bodo), with smaller shares of Scheduled Castes and minimal Muslim presence compared to neighbouring plains constituencies. The electorate features a mix of Bodo tribal communities, other indigenous groups, and limited non-tribal settlers, contributing to its tribal-dominated character.
The Sidli-Chirang constituency covers parts of the Chirang district in Lower Assam with flat alluvial plains in the south transitioning to gentle undulations and low hills towards the north near the Bhutan foothills. The terrain supports paddy cultivation, horticulture, and forest-based activities with patches of moist deciduous and sal forests, but is prone to seasonal flooding from rivers like the Gaurang, Champamati, and Saralbhanga. Livelihoods in Sidli-Chirang depend mainly on agriculture (paddy, vegetables, and Eri silk), small trade, government services, and emerging tourism. Fertile soils and abundant rainfall sustain these activities. Infrastructure includes excellent road connectivity via National Highway 27, rail access at nearby stations like Kokrajhar or Bongaigaon (about 20-40 km away, depending on the village), and basic amenities in the town with ongoing developments in rural roads, tribal welfare, and connectivity.
The nearest major town is Kokrajhar to the west, about 35 km away, and Bongaigaon to the east, about 30 km away. The state capital, Dispur/Guwahati, lies around 200-220 km east. The constituency lies close to the international border with Bhutan in the north (foothills distance around 20-40 km in parts).
Although it was a four-cornered contest for the Sidli-Chirang constituency, the main fight was confined between two Bodo parties, the BJP’s ex-ally UPPL and its current ally BPF. UPPL fielded Ranjit Basumatary as its candidate, and the BPF named Paniram Brahma as its candidate. Matilal Narzary was the Congress’s candidate, while Banima Brahma was in the fray as the Voters International Party candidate. The BPF, which already was a force to reckon with in this region, was expected to have benefited from its pre-poll decision to join the BJP-led NDA and enjoyed an edge over its opponents. The 2026 elections witnessed a robust turnout, which stood at 84.56 per cent as of 5 pm on April 9, with the final figure, though, likely to change and increase further. One may, however, have to wait till May 4 when counting of votes is taken up to know which way the Sidli-Chirang electorate votes.
