Ieng Sary
Those leftists who remained were encouraged to form a legal political party to contest elections: this was the Krom Pracheachon, which had a socialist platform. The Communist Party itself (led by Tou Samouth and Sieu Heng, and including later prominent figures such as Saloth Sar (Pol Pot) and Ieng Sary) continued as a purely clandestine organisation.
