The Communist Party of India (Marxist) (abbreviated as CPI(M) or CPM) is a communist political party in India that formed as the result of a split in the Communist Party of India (CPI) in 1964.
A chief minister is the head of government of each of the twenty-eight states and three union territories (Delhi, Jammu and Kashmir and Puducherry).
In accordance with the Constitution of India, the governor is a state's de jure head, but de facto executive authority rests with the chief minister.
Following elections to the state legislative assembly, the state's governor usually invites the party (or coalition) with a majority of seats to form the government.
[2] As of March 2020[update], nine people from the CPI(M) have held the position of a chief minister — four in Kerala, three in Tripura, and two in West Bengal, out of which only one — Pinarayi Vijayan is incumbent.
