About CPI(M)
Split from the CPI in 1964 over ideological differences with Moscow. Led West Bengal's Left Front government for 34 unbroken years (1977–2011) — Jyoti Basu alone served 23 years, independent India's longest continuous chief-ministership — before losing to the AITC in 2011. Also led Kerala's government repeatedly, alternating with Congress-led fronts, and Tripura continuously from 1993 to 2018, when the BJP ended its 25-year rule there. Currently governs Kerala.
