NCP State President Jose Philip D'Souza said the cabinet should not have a tainted minister.
"He should resign immediately. By keeping him in the cabinet BJP is proving that it is the party with tainted faces," he said.

AAP has served ultimatum of 15 days for the state government to sack the minister, failing which they have decided to approach Governor with a petition.
