Dinhata is a prominent assembly constituency located in Cooch Behar district of West Bengal. The constituency, which includes both urban and rural segments, holds considerable political significance in north Bengal. Known for its dynamic electoral history, Dinhata has witnessed intense contests involving the All India Trinamool Congress (AITC), Bharatiya Janata Party (BJP), and the All India Forward Bloc (AIFB). Political alignments in the constituency often reflect broader shifts in voter sentiment across the district.
In the 2021 West Bengal Assembly elections, Dinhata was won by Nisith Pramanik of the Bharatiya Janata Party (BJP). He secured a decisive victory over his nearest rival from the All India Trinamool Congress (AITC) by a margin exceeding 57,000 votes. However, Pramanik later resigned from the Assembly seat after being elected to the Lok Sabha and appointed as a Union minister. This led to a by-election in the same year.
In the 2021 bypoll, the seat was won by Udayan Guha of the All India Trinamool Congress (AITC), who defeated the BJP candidate by a substantial margin. The by-election result reversed the Assembly outcome and restored the seat to the ruling party, highlighting the constituency’s evolving political landscape.
Key issues in Dinhata include infrastructure development, employment opportunities, and agricultural concerns. Rural voters frequently raise demands related to irrigation, crop support, and flood management, while urban residents focus on road conditions, drainage, and civic amenities. Access to healthcare and educational facilities also remains a recurring concern.
