Mohan Bikram Singh (born 15 April 1935),[1] often referred to as MBS, party name Gharti,[citation needed] is a Nepalese communist politician.
[2] He then began actively promoting communism and training local youth and peasants to oppose landholders in the area around Narikot, Pyuthan in 1953-54.
This was taking place in the context of a growing nationwide peasant movement in Nepal in the post-Rana years of 1950-1960.
In 1961, when the party was divided in different tendencies, MBS rallied the leftist sections, raising the demand for a Constituent Assembly.
Together with Shamburam Shrestha and Nirmal Lama they formed the 'Central Nucleus', which sought to unify with Communist Party of Nepal (Pushpa Lal).
Following the restoration of democratic rule, CPN(UC-M) was divided on issues like whether the party should join the coalition government.
