In the 2020 Assembly elections, he defeated Satyanarayan Singh of Bhartiya Janata Party, who was his nearest political rival.

[3] Singh, who was a businessman in his earlier life, was aspiring to ticket from Upendra Kushwaha's Rashtriya Lok Samata Party to contest from Dehri Assembly constituency in 2015.

In 2019, the by-polls were conducted in the Dehri constituency, to fill the vacancy arising out of the revocation of the membership of Muhammad Ilyas Hussain in Bihar Legislative Assembly.

[8][9] Singh has publicly spoken against the expenditure done on celebration of Dussera and has condemned brahminical views on existence of 33 crore deities in Hinduism.

In October 2023, he made a public statement that goddess Durga is an imaginary figure and the epic tales of her fight with army of demons is also fabricated.
