But, Mamata Banerjee's political career reached its peak when she defied all odds to become West Bengal's first woman chief minister, bringing an end to the 34-year-long Left regime in the state.
Banerjee's eventful life and political career is the subject of a new book "Decoding Didi".
Penned by journalist Dola Mitra, the book explores the various facets of the chief minister -- sometimes being eulogized as a leader of the masses, and at other times being pilloried as a mad, whimsical dictator.
"Very few politicians in India today generate as much interest as does the chief minister of West Bengal, Mamata Banerjee popularly known as 'Didi'.
"Diminutive yet defiant; unassuming yet arrogant; always volatile, though now increasingly erratic, Didi remains a puzzle. The book is an essential guide to understanding one of the most significant forces in contemporary Indian politics," publishers Rupa Publications said in a statement.
The book documents the heady days of the elections which toppled the Left regime raising hopes for a political renaissance in West Bengal and the crushing disappointment at Mamata Banerjee's failure to bring about any meaningful change.
A clear-sighted account, "Decoding Didi" digs deep into her success, while also shedding light on a politician who has been scathingly criticized and ridiculed for "failing to deliver on the dream she once promised her constituents".
