Addressing a rally here, BJP president Amit Shah asked Banerjee to rein in her workers and associates who were allegedly involved in corruption and scam and said, "If you can't do that then please step down.
"BJP will provide good governance in Bengal. The countdown has already started and the people of Bengal will show you the way out in the 2016 Assembly polls."
Criticising Banerjee, the BJP president said, "You (Mamata) are not protesting against duping of 17 lakh investors in the Saradha scam and coming down on the streets, because your own associates and stooges are involved. We need an answer as to who took away the Saradha scam money.
"We are not afraid of anyone because our workers are not involved in any scam. Whether it's Saradha or anything else, we will do the work of arresting and putting the culprits behind bars," he said.
"There should not be any politics on CBI. It should be allowed to work impartially without any political pressure. The Prime Minister should ensure that the CBI is not a pawn in the hands of the party in power at the Centre," he said.
