Chief Minister of West Bengal

The chief minister of West Bengal (IAST: Paścim Baṅgēr Mukhya Mantrī) is the de facto head of the executive branch of the Government of West Bengal, the subnational authority of the Indian state of West Bengal. The chief minister is head of the Council of Ministers and appoints ministers. The chief minister, along with their cabinet, exercises executive authority in the state. The governor appoints the chief minister, whose council of ministers are collectively responsible to the assembly.

On 17 August 1947, the British Indian province of Bengal was partitioned into the Pakistani province of East Bengal and the Indian state of West Bengal. Since then West Bengal has had seven chief ministers, starting with Prafulla Chandra Ghosh of the Indian National Congress (INC) party as the premier (elected to lead the assembly while the chief minister is not appointed). Dr. Bidhan Chandra Roy in 1950 became the first formal chief minister of West Bengal after the implementation of the Indian Constitution. A period of political instability followed thereafter—West Bengal witnessed three elections, four coalition governments and three stints of President's rule between 1967 and 1972—before Siddhartha Shankar Ray of the INC served a five-year term.

The landslide victory of the Communist Party of India (Marxist)-led Left Front in the 1977 election began Jyoti Basu's 23-year continuous reign as chief minister. The length of his tenure was an all-India record until 2018, when he was surpassed by Sikkim's Pawan Kumar Chamling. Basu's successor Buddhadeb Bhattacharya continued the communist rule in West Bengal for another decade, when the Left Front was defeated in the 2011 election by the Trinamool Congress, thereby ending the 34-year long rule of the Left Front government, a fact that was noted by the international media. Sworn in on 20 May 2011, Trinamool Congress leader Mamata Banerjee is West Bengal's incumbent chief minister, the first woman to hold the office. She was subsequently voted to power in 2016 and 2021 assembly elections. She is one of the two female incumbent chief ministers in India as of 2024.
