He then formed a party of the same name, with a break-away faction, and joined the BNP-led alliance in January 2014.
Born in 1939, Zafar entered politics as a student of Dhaka University.
Kazi Zafar entered public life during the pre-independence turmoil in the erstwhile East Pakistan in the 1960s as a Maoist leader, attracting a large following and was general secretary of the East Pakistan Chhatra Union in 1962-63.
