Bengal alone accounted for about 54% of BJP's Rs 529.38 crore spend across five polls, with Rs 286.99 crore earmarked for the state. In 2026, the party poured Rs 217.16 crore into general campaigning and Rs 69.83 crore on candidate expenses in Bengal, a figure that eclipses the Congress's Rs 42.08 crore spent in the state, which was split between Rs 12.96 crore for general campaigning and Rs 29.12 crore for candidate costs.
The hefty outlay coincided with BJP's historic sweep, winning 207 of 293 seats; a resident of Kolkata recalled how nightly rallies filled the streets, “the air smelled like diesel and hope.” Yet TMC managed only 80 seats, and Congress captured a mere two. In Kerala, the narrative flipped: Congress spent Rs 105.34 crore to BJP's Rs 82.67 crore and secured 63 seats, while BJP managed only three.
BJP's central office received Rs 1,472.8 crore during the election period, ending with a balance of Rs 7,627.2 crore—up from Rs 6,722.6 crore when the polls were announced. Congress's receipts fell sharply from Rs 169.06 crore to Rs 103.2 crore across its headquarters and state units. BJP's Rs 529.38 crore spend dwarfs Congress's Rs 248.55 crore total across all five contests, and CPI(M)'s combined expenditure of Rs 39.04 crore sits far below both.
The Election Commission will examine the filings for compliance with the Representation of People Act, and a detailed audit is slated for early 2027. The outcome could affect future campaign financing rules and the political calculus for the next general election.
