With Anna Hazare demanding filing of FIRs against 14 union ministers by August, information and broadcasting minister Ambika Soni Monday said the social activist should provide proof against them.
"They should give some proof. How will government work if it keeps ordering investigations? There are many other works to be completed," Soni told reporters.
She said the United Progressive Alliance (UPA) government has made serious efforts to curb corruption.
In his rally at Jantar Mantar on Sunday, Hazare had threatened a nationwide agitation if the government failed to register complaints against 14 cabinet ministers.
