Magrahat Purba, located in the Diamond Harbour Subdivision of South 24 Parganas district of West Bengal, is a Scheduled Caste-reserved Assembly constituency comprising the entire Magrahat II community development block that includes the Magrahat town, along with 14 gram panchayats or 78 inhabited villages, lending it a mixed demography and overwhelmingly rural character. It is one of the seven assembly segments under the Jaynagar Lok Sabha constituency. It was a CPI(M) bastion for a long time, which over the years has become a stronghold of the Trinamool Congress.
Magrahat Assembly constituency was originally established in 1951 as a twin-seat constituency, with the Congress party winning both seats on offer in the 1952 and 1957 elections. It was split into Magrahat Paschim, which became a general category Assembly seat, and Magrahat Purba, designated as a reserved constituency for the Scheduled Caste community, in 1962. Magrahat Purba has voted in 15 Assembly elections since it came into existence, with the CPI(M) winning the seat 10 times, including a streak of seven consecutive victories between 1977 and 2006, while the Congress party held the seat twice, and the Trinamool Congress has remained unbeaten here in the last three elections.
The Trinamool Congress had to work hard to snatch the seat from the CPI(M) as it endured two defeats at the hands of the CPI(M) in 2001 and 2006. It persisted with its candidate Namita Saha, who faced defeats thrice, including once in 1996 as a Congress nominee, before turning the table on the CPI(M). Namita Saha defeated her CPI(M) rival Chandan Saha by 8,803 votes in 2011 and by 9,560 votes in 2016. Her third win came in 2021 when Saha’s victory margin surged to 54,079 votes over Chandan Kumar Naskar of the BJP, while the CPI(M) tumbled down to third place. Notably, all three parties have persisted with the same leaders in all three elections.
The voting trends during the Lok Sabha elections in the Magrahat Purba Assembly segment also indicate near total dominance of the Trinamool Congress. In 2009, the Socialist Unity Centre of India (Communist) led in this segment over the Revolutionary Socialist Party by 19,199 votes. That was the only parliamentary election in which the Trinamool Congress was not in sight. Thereafter, it tightened its control as it led the RSP by 15,082 votes in 2014, which has since increased with each election as the BJP emerged as its principal challenger. Trinamool led the BJP by 37,644 votes in 2019 and by 46,871 votes in 2024.
The number of voters in Magrahat Purba has declined by 14,129 voters following the 2025 SIR exercise carried out by the Election Commission. The draft electoral roll as on January 1, 2026, has listed 237,808 voters in this constituency, while it stood at 251,937 in 2024, 242,530 in 2021, 228,612 in 2019, 212,019 in 2016 and 177,554 in 2011.
Although the Magrahat Purba Assembly constituency is reserved for the Scheduled Caste community, they are outnumbered by the Muslim voters. Scheduled Castes consist of 34.61 per cent of the voters compared to 44.90 per cent of the Muslim electorate. It is a predominantly rural seat with 71.70 per cent of its voters based in villages and 28.30 per cent urban voters living in the Magrahat town. The turnout has remained robust with 85.30 per cent in 2011, 86.72 per cent in 2016, 82.51 per cent in 2019 and 85.30 per cent in 2021.
Magrahat Purba lies in the southern part of the South 24 Parganas district in the flat alluvial plains of the lower Ganges delta, with low-lying terrain and fertile soils typical of coastal Bengal. The area is prone to seasonal flooding and salinity ingress in some pockets due to tidal influence. Major rivers include the Hooghly to the west, the Matla and Bidyadhari flowing farther east, with numerous canals and drainage channels supporting irrigation and agriculture.
The economy is largely agrarian with paddy, vegetables, betel leaf, potato and some cash crops as main produce, alongside pisciculture in ponds and canals. Small-scale trade and commuting to Kolkata supplement incomes. Infrastructure is rural with electricity, drinking water and markets in villages and the town, while road connectivity is good through state highways and district roads. Rail access is provided by Magrahat railway station in the town on the Sealdah-Lakshmikantapur line, offering suburban trains to Sealdah and Kolkata.
Nearby towns and approximate road distances include Diamond Harbour, the subdivision headquarters, at about 15 to 20 km, Baruipur, the district headquarters, at 25 to 30 km, Jaynagar at 40 to 45 km, Canning at 35 km, Budge Budge at 30 km, Maheshtala at 20 km, and the state capital Kolkata at 40 to 50 km with central landmarks like Esplanade at about 45 km. Other towns in South 24 Parganas include Falta around 25 km, and Kakdwip farther south, while adjoining districts feature places in Howrah like Uluberia, around 50 km west.
The deletion of 14,129 names from the draft roll could be a contentious issue with the Trinamool Congress accusing the Election Commission of targeting the Muslim community. Even if the final electoral roll remains unchanged, it might not have a telling impact on the outcome in Magrahat Purba constituency, given its huge leads over the BJP in the last three elections. Barring the unexpected, Trinamool Congress may have reasons to feel secured of another victory here in the 2026 Assembly elections, though its margin might decline as a result of the SIR and anti-incumbency factor.
