"Those in alliance with the BJP in Bihar should ensure that reservation is given and not demanded. Mere hollow statements and cheap publicity on the matter will not suffice.
The Bihar chief minister should initiate action at his level also," Mayawati said.
She said BSP reiterates its demand of quota for Dalits, OBC in private sector and also the economically poor among the upper castes and Muslim community.
Mayawati also demanded quota in promotions by amending the Constitution.
The Bihar chief minister has said his government favoured reservations in the private sector "in-principle".
"But for (introducing) that Parliament has to take initiative in accordance with provisions of the Constitution," he said yesterday.
RJD supremo Lalu Prasad too targeted Kumar over his remarks favouring reservation in the private sector, saying it was not a new idea and that the state has seen little private investment.
Prasad, however, said his party is not against the idea of reservation in the private sector.
"We are also in favour of reservations in the private sector, but this is not a new demand. Mayawati had raised similar demands and so had Ram Vilas Paswan," the RJD supremo has said.
