The Trinamool Congress’s tally fell to 80 seats from 215, while the BJP’s vote share rose to 45.8% against the TMC’s 40.8%.

West Bengal has been one of the few large states where a non-BJP leader could still claim real national weight, and Banerjee’s fall removes that counterweight at exactly the moment the opposition alliance is already fractured. The BJP now holds an electoral breakthrough in a state it had never governed, strengthening its grip across eastern India and giving Narendra Modi’s camp a cleaner national narrative: the opposition cannot even hold its own strongholds. [The Hindu](https://www.thehindu.com/elections/west-bengal-assembly/west-bengal-election-results-2026-trinamool-ousted-as-bjp-sweeps-west-bengal/article70939323.ece "thehindu.com") [The Straits Times](https://www.straitstimes.com/asia/south-asia/indian-chief-minister-refuses-to-resign-after-election-defeat-to-modis-bjp "straitstimes.com") Banerjee’s response shows the political trap she is in. She has refused to resign, called the result “immoral,” alleged that around 100 seats were “forcibly taken,” and said she will now work to “strengthen” the INDIA bloc; Election Commission officials and BJP leaders have dismissed her claims as baseless and constitutional. That leaves her still loud, but with sharply reduced leverage. [The Straits Times](https://www.straitstimes.com/asia/south-asia/indian-chief-minister-refuses-to-resign-after-election-defeat-to-modis-bjp "straitstimes.com") [The Hindu](https://www.thehindu.com/elections/west-bengal-assembly/no-question-of-resigning-as-cm-we-did-not-lose-elections-says-mamata/article70942822.ece "thehindu.com") ## What to watch next The next decision point is whether Banerjee takes the result to court, continues as chief minister until the end of her term on **May 7**, or shifts immediately into opposition mobilization. [The Straits Times](https://www.straitstimes.com/asia/south-asia/indian-chief-minister-refuses-to-resign-after-election-defeat-to-modis-bjp "straitstimes.com") More important is whether INDIA bloc leaders rally around her or quietly pivot away. Sonia Gandhi, Rahul Gandhi, Akhilesh Yadav, Hemant Soren and Tejashwi Yadav have already called her, but the alliance’s central problem remains unchanged: it has regional leaders with local bases, not a single national command structure.
