Chief Minister Mamata Banerjee and the Bharatiya Janata Party (BJP) are preparing for a high-stakes contest in the 2026 West Bengal assembly election [1].
The outcome of the election depends heavily on the "Presidency region," a cluster of districts that serves as a political kingmaker. Control of this area could determine whether the state maintains its current leadership or shifts toward the BJP.
The Presidency region includes the districts of Kolkata, Howrah, Nadia, and both North and South 24 Parganas [1]. This specific geographic area contains 108 seats [1], which represents approximately 37% of the total assembly seats in the state [1].
For the BJP, the upcoming election is an attempt to shift power in West Bengal. The party is challenging the long-term incumbency of Mamata Banerjee, who has led the state for 15 years [2]. The BJP aims to dismantle the existing power structure and establish a new mandate in the region [2].
Banerjee is focused on defending her political turf against the BJP surge [2]. Her strategy involves maintaining hold over the critical districts that comprise the Presidency region to ensure her party's continued dominance in the legislative assembly [1].
The competition centers on these specific districts because of their high concentration of seats relative to the rest of the state. Because the Presidency region holds more than one-third of the assembly's power, neither party can afford to lose significant ground in these areas [1].
“The Presidency region includes the districts of Kolkata, Howrah, Nadia, and both North and South 24 Parganas.”
The concentration of 37% of the state's legislative seats within the Presidency region creates a geographic bottleneck for political power. If the BJP can successfully penetrate these specific districts, it could overcome the incumbency advantage held by Mamata Banerjee, effectively turning a regional shift into a state-wide change of government.
