Communist Marxist Party (CMP) was a political party in Kerala. The party was founded in 1986 when CPI(M) leader M. V. Raghavan was expelled from the CPI(M) due to a grave difference of opinion regarding the formation of alliances with the IUML. His support for forming a united front with non-secular parties such as the Muslim League in order to take on alliances led by the INC was ultimately rejected by the CPI(M) leadership. He was subsequently expelled from the Party.
