Since 1947, there have been eight Chief Ministers of West Bengal. The first was Prafulla Chandra Ghosh of the Indian National Congress, who was succeeded by his party - mates Dr Bidhan Chandra Roy and Prafulla Chandra Sen. A decade of instability followed, marred by fractious coalition governments and frequent impositions of President 's rule. The instability ended with 1977 election victory of the Communist Party of India (Marxist) (CPM). Headed by Jyoti Basu, the CPM - led Left Front government was in office for over 23 years (1977 -- 2000), making Basu India 's longest - serving chief minister ever. Left rule in West Bengal continued for another 10 years under Buddhadeb Bhattacharya, before its defeat in the 2011 election by the Trinamool Congress. Appointed on 20 May 2011, Trinamool leader Mamata Banerjee is the current incumbent, the state 's first woman chief minister.
