Communist Party of India (Marxist)

The Communist Party of India (Marxist) (abbreviated as CPI(M)) is a communist political party in India. It is the largest communist party in India in terms of membership and electoral seats, and one of the six national parties of India. The party was founded through a splitting from the Communist Party of India in 1964; it quickly became the dominant faction.

The 34 years of CPI(M)-led Left Front rule in West Bengal was the longest-serving democratically elected communist-led government in the world. It emerged as the third largest party of the parliament in 2004 national election. Presently, CPI(M) is a part of ruling alliances in two states - the LDF in Kerala, which it leads, and the SPA in Tamil Nadu. It also has representation in the legislative assemblies of seven states.

The All-India Party Congress is the supreme authority of the Communist Party of India (Marxist). However, during the time between two party congresses, the Central Committee is the highest decision-making body. The Central Committee shall elect from among its members a Polit Bureau including the General Secretary. The Polit Bureau carries on the work of the Central Committee between its two sessions and has the right to take political and organisational decisions in between two meetings of the Central Committee.

CPI(M) had a total income of ₹1,620,000,000 in fiscal year 2021–22. The party reported zero funding from Electoral Bonds.
