He also alleged that Prime Minister Narendra Modi, along with Shah, was indulging in a "heinous" act of using departments like the Income Tax to target opposition leaders, which no otherpolitical leader has done in the past.
Stating that no political party or leader or Prime Minister had indulged in "hate politics of this nature", he said "to defeat and liquidate opposition party, no one had indulged in such cowardly act."
"So it is right to call Amit Shah- coward."
Condemning Rao's comments against Modi and Shah as "derogatory", BJP state President B S Yeddyurappa in a statement said "by making such comments he is proving that he is unfit to be in pubic life."
He said the Income Tax department was an organisation thatfunctions independently and making such comments was "irresponsible", "immature" and "childish" on part of Rao.
The Congress party and Chief Minister Siddaramaiah had earlier too accused the Modi government of using the Income Tax Department for its "political conspiracies", following searches by the department at multiple propertiesrelated to senior minister D K Shivakumar in August last year.
