Trained with Limaye,he was always a Mulayam man

A close associate of socialist Madhu Limaye,he participated in the JP movement and was jailed for 20 months during Emergency.

He was later elected to the UP Assembly and made a Minister of State. Mohan Singh had thrown his lot with Mulayam Singh Yadav during his tussle with rivals and had since been closely associated with the SP chief.

He was elected to the Lok Sabha first as a Janata Dal candidate. He was elected to Lok Sabha twice as SP candidate. After he lost the last Lok Sabha elections,the SP chief sent him to the Rajya Sabha in 2010.

Given his socialist training,Yadav used to entrust him with all political literature for the party,be it resolutions for national executive or election manifestoes.

Singh was a man of letters and apart from writing columns in newspapers,had written several books including,History of Socialist Movement,Dr. Ambedkar-A Multifaceted Personality,and Freedom Movement and Socialist Contribution,and was learnt to be compiling recollections of his political journey before his death. In the run up to the 2012 Assembly elections,on the issue of induction of controversial leader DP Yadav,Singh had contradicted Akhilesh Yadav,who publicly rejected suggestions of his reinduction. Singh was soon divested of his responsibility as national spokesman. Singh had been under medication for over a year now.
