For over a decade, Mamata Banerjee dominated West Bengal politics, building a formidable base through welfare schemes, grassroots mobilisation, and strong anti-BJP positioning. However, this election has delivered a decisive blow to the Trinamool Congress (TMC), marking a major political and psychological setback. Facing anti-incumbency, corruption allegations, and an aggressive campaign by the Bharatiya Janata Party (BJP), Mamata's long-standing dominance has been dented. The verdict not only reshapes Bengal's political landscape but also weakens her stature as a key national opposition figure, potentially altering broader opposition dynamics across India.
