PATNA: PM Narendra Modi countered the Grand Alliance’s claims that the NDA was trying to dilute the present job reservation system by alleging that Bihar ’s ruling alliance was conspiring to introduce quotas on the basis of religion. At a rally in Buxar on Monday he said he was willing to ‘give up his life’ for protecting the existing quota system for beneficiaries.Modi’s injection of the religious angle to the quota debate came amid the Grand Alliance claims that there was a threat to the present quota beneficiaries as RSS chief Mohan Bhagwat had said that the current reservation system should be reviewed to include economically weaker sections."If Laluji, Nitishji and Madam Soniaji have the courage, they should reply," Modi said. The framers of the Constitution were against religion-based reservations, Modi said and added political parties used to declare 2-5 per cent reservation to woo certain section of voters during elections. "The Supreme Court has taken a decision that the quota limit should not cross 50 per cent," Modi said."They are working out sinful plan," Modi alleged, mentioning the names of CM Nitish Kumar , RJD chief Lalu Prasad and AICC chief Sonia Gandhi
