Singh, a two-time MP and three-time MLA, switched from the Congress to the BJP in 2014 and was also a minister in the previous PDP-BJP government in Jammu and kashmir which collapsed in June 2018 after the national party pulled out of the alliance. Several months before the fall of the government, Singh resigned from the BJP and floated the DSSP following an uproar over his participation in a rally held in support of the accused in a rape and murder case involving an eight-year-old girl in Kathua in January 2018.
