Prime Minister Narendra Modi's Bharatiya Janata Party achieved a landmark victory in West Bengal, winning 208 of 294 seats to end 15 years of Mamata Banerjee's rule. The stunning reversal from just 3 seats a decade ago marks the Hindu nationalists' first conquest of one of India's most populous states and political bastions.

The win continues B.J.P.'s state election resurgence since losing its parliamentary majority in 2024. The party now controls most regional parliaments nationwide after victories from Assam to Maharashtra. West Bengal, with its 100 million residents, stood as the final major obstacle to B.J.P.'s nationwide dominance.

Business leaders anticipate policy alignment with Modi's Hindu-first agenda, potentially affecting investment patterns in West Bengal. The state's industrial sector may see regulatory changes as B.J.P. implements its national development model. Regional businesses face uncertainty as the new government establishes its economic priorities.
