This comes a day after the Enforcement Directorate filed the first charge sheet in the case involving the role of arrested LIC agent Anand Chauhan.
"Virbhadra Singh should have resigned on moral grounds after the CBI raids and attachment of property by ED but he did not see the grace but after filing of charge sheet against Anand Chauhan, the Congress high command should sack him," chief spokesman of the party Rajiv Bindal said.
Bindal said that Anand Chauhan was only a "commission agent" of LIC whereas Virbhadra Singh and his wife were the main accused and as such he should immediately resign after filing of charge sheet.
He also chided the Congress high command for turninga "blind eye" towards the "misdeeds" of the senior party leader.
