. The party made its debut at a press conference on 7 April 2013. It was formed by members of BSD under the leadership of Mubinul Haider Chowdhury who did not agree with party's policy towards Ganajagaran Mancha and Shivdas Ghosh. This faction wanted Shivdas Ghosh to be declared the international authority of the communist movement. Mubinul Haider Chowdhury was elected General Secretary of the 9-member Central Working Committee at a Special Central Convention held on 20–23 November 2014. Due to the lack of proper application of ideology in the organization, a breakdown took place in February 2020. The rift was accelerated by the expulsion of 18 leaders and activists, including Shuvrangshu Chakraborty. This rebel fraction tried to form a new party called the Socialist Party of Bangladesh (Marxist) - Central Pathchakra Forum. Later on 3 April 2021 this fraction under the leadership of Subhangshu Chakrabarty launched the
Communist Movement of Bangladesh (CMB). In a press conference the rebel leader Subhangshu Chakrabarty claimed that CMB is the only party in Bangladesh with a true revolutionary Marxist idea. == See also ==
