Mamata Banerjee Loses Bhabanipur Seat to Suvendu Adhikari by 15,105 Votes as BJP Ends TMC’s 15-Year Rule in West Bengal
BJP’s Suvendu Adhikari Defeats Chief Minister Mamata Banerjee on Her Home Turf in Bhabanipur
In what is being described as one of the most dramatic political upsets in modern Indian history, West Bengal Chief Minister Mamata Banerjee has lost her own constituency of Bhabanipur to BJP’s Suvendu Adhikari by a margin of 15,105 votes, sealing the end of the Trinamool Congress’s 15-year rule in the state. The result, which came during the final rounds of counting on May 4, 2026, sent shockwaves through Indian politics and confirmed the BJP’s historic first-ever government formation in West Bengal.
Adhikari, who had served as a trusted lieutenant of Banerjee before defecting to the BJP ahead of the 2021 elections, secured a decisive victory in what was widely seen as the most closely watched constituency battle in these elections. The result mirrors his earlier triumph in Nandigram in 2021, but this time the stakes were far higher — he had ventured into Banerjee’s own political bastion.
The Numbers Behind the Historic Defeat
According to Election Commission of India data, Suvendu Adhikari polled significantly more votes than Banerjee in the Bhabanipur Assembly constituency. The initial rounds of counting saw Banerjee take an early lead after the third round, but Adhikari surged ahead in subsequent rounds and never looked back. By the time counting concluded, the margin had widened to over 15,000 votes — a comprehensive defeat for the three-time Chief Minister.
The broader picture was equally devastating for the TMC. Across West Bengal’s 294 Assembly seats, the BJP won 206 seats, securing a commanding majority that few had predicted would be this large. The TMC, which had won 213 seats in 2021, was reduced to just 80 seats (winning 64 and leading in 16 at the time of final trends). The Congress managed a meagre 2 seats, while other parties were virtually wiped out. Browse more on Social Trends for the latest developments.
Mamata’s Explosive Allegations After Defeat
In the hours following her defeat, Mamata Banerjee made explosive allegations about the counting process. A phone call shared by TMC MP Kalyan Banerjee revealed the Chief Minister claiming that “goons entered and beat me up” at the Bhabanipur counting centre. She alleged irregularities during the counting process, including intimidation of her party agents and procedural lapses in handling Electronic Voting Machines (EVMs).
Banerjee further claimed that her agents were removed from counting centres and that the outcome would be legally challenged with supporting evidence. The TMC supremo was reported to have been visibly emotional as results turned against her, with video footage showing her emerging from the strong room in a visibly distressed state.
Nine TMC Ministers Lose Their Seats
The scale of the TMC’s defeat extended well beyond Banerjee’s personal loss. At least nine sitting TMC ministers lost their seats in the BJP wave that swept across the state. The anti-incumbency wave, combined with the BJP’s aggressive campaign centred on issues of governance, corruption, and law and order, proved too strong for the ruling party to withstand.

How BJP Built Its Bengal Victory
The BJP’s strategy in West Bengal was years in the making. The party had steadily expanded its footprint from winning just 3 seats in 2016 to 77 in 2021, and finally crossing the 200-mark in 2026. Several factors contributed to this historic breakthrough:
Anti-incumbency against TMC: After 15 years of TMC rule, voters expressed frustration over governance issues, alleged corruption, and the party’s perceived authoritarian tendencies. The RG Kar rape and murder case, which sparked massive protests across Bengal, became a major political flashpoint that the BJP capitalised on effectively.
Central security deployment: The election was conducted under unprecedented central security deployment, with over 700 paramilitary companies stationed across the state. This heavy security presence, according to analysts, gave voters the confidence to vote freely without fear of intimidation — a factor that many believe worked in the BJP’s favour.

Suvendu Adhikari’s grassroots connect: As Leader of the Opposition, Adhikari had spent five years building the party’s organisational strength across Bengal, particularly in rural areas that were once considered TMC strongholds. His decision to contest from Bhabanipur was seen as a bold move that ultimately paid off spectacularly.
What Happens Next for Bengal Politics
With the BJP set to form its first government in West Bengal, all eyes are now on who will become the state’s new Chief Minister. The party has appointed Union Home Minister Amit Shah as the central observer for the election of the Leader of the BJP’s Legislative Party, signalling that the decision will be made at the highest levels of the party leadership.

Among the frontrunners for the CM post are Suvendu Adhikari himself, former state president Dilip Ghosh, current Bengal BJP president Shamik Bhattacharya, BJP MLA from Asansol South Agnimitra Paul, and Siliguri MLA Shankar Ghosh. The final decision is expected to involve Prime Minister Narendra Modi and the BJP’s central leadership.
Mamata’s Political Future Under a Cloud
For Mamata Banerjee, the defeat marks a potentially career-defining moment. Having built the TMC from scratch and single-handedly ended the Left Front’s 34-year rule in 2011, she now faces the prospect of sitting in opposition for the first time since coming to power. Political analysts note that at 71, a comeback will be an uphill battle, especially given the scale of the BJP’s mandate.
Banerjee has indicated she will hold a press conference and is expected to outline her party’s strategy going forward. She has also hinted at legal challenges to the election results, though most observers believe the margin of the BJP’s victory makes any reversal unlikely.

PM Modi Celebrates Historic Victory
Prime Minister Narendra Modi addressed BJP workers at the party headquarters in New Delhi, describing the Bengal result as a triumph of democracy and development. “The people of Bengal have shown that they want good governance, and the BJP will deliver on their aspirations,” Modi said. Victory rallies were held across Bengal, though the state administration imposed restrictions on large gatherings to prevent any potential post-poll violence.
The BJP’s Bengal victory is significant not just for the state but for national politics, as it gives the party a foothold in the last major opposition-ruled state in the east. Combined with its dominance in Assam (where it won close to 100 seats), the BJP has now established near-complete political control across India’s northern and eastern heartland.
