Banerjee previously served twice as Minister of Railways, the first woman to do so. She is also the first female Minister of Coal, and Minister of Human Resource Development, Youth Affairs and Sports, Women and Child Development in the cabinet of the Indian government. She rose to prominence after opposing the erstwhile land acquisition policies for industrialisation of the Communist government in West Bengal for Special Economic Zones at the cost of agriculturalists and farmers at Singur. In 2011 Banerjee pulled off a landslide victory for the AITC alliance in West Bengal, defeating the 34-year-old Communist Party of India (Marxist)-led Left Front government, the world's longest-serving democratically elected communist government, in the process.
