Banerjee, who formed the Trinamool in 1998 by breaking away from the Congress to fulfill her life's mission of taking on the then entrenched Communist Party of India-Marxist led (CPI-M) Left Front, not only won handsomely with a 25,000 plus margin from Bhabanipur, but also made the Trinamool the only party in the state to emerge victorious in the assembly election by fighting alone since 1962.
