For a few years, Pushpa Lal's party was the major communist group in Nepal.
Pushpa Lal called for unity in action together with the Nepali Congress against the royal regime.
Bijukchhe also criticized the line of seeking cooperation with Nepali Congress and the failure of the party to condemn the Soviet Union as imperialist.
In 1976, a prominent student leader of Pushpa Lal's party, Madan Kumar Bhandari, broke away and formed the Mukti Morcha Samuha.
Under Pradhan's leadership the party steered along a moderate course, endorsing Pushpa Lal's policy of cooperation with the Nepali Congress.
