Political Carrier :-
Banerjee began her political career in the Congress party, and as a young woman in the 1970s, she quickly rose in the ranks of the local Congress group, and remained the general secretary of Mahila Congress (I), West Bengal, from 1976 to 1980. In the 1984 general election, Banerjee became one of India's youngest parliamentarians ever, defeating veteran Communist politician Somnath Chatterjee, to win the Jadavpur parliamentary Constituency in West Bengal. She also became the general secretary of the Indian Youth Congress. Losing her seat in the 1989 general elections in an anti-Congress wave, she was reelected in the 1991 general elections, having settled into the Calcutta South constituency. She retained the Kolkata South seat in the 1996, 1998, 1999, 2004 and 2009 general elections.
In the Rao government formed in 1991, Banerjee was made the Union Minister of State for Human Resources Development, Youth Affairs and Sports, and Women and Child Development. As the sports minister, she announced that she would resign, and protested in a rally at the Brigade Parade Ground in Kolkata, against the Government's indifference towards her proposal to improve sports in the country. She was discharged of her portfolios in 1993. In April 1996, she alleged that Congress was behaving as a stooge of the CPI-M in West Bengal. She claimed that she was the lone voice of reason and wanted a "clean Congress".
