BJP MP Sambit Patra criticised Congress and Opposition for their stance on Aadhaar and said that they once challenged Aadhaar-voter linking but now demand its inclusion. He further said this shift exposes their "double standards" on Aadhaar's role in electoral forms. Patra's remark came after Supreme Court told ECI to consider Aadhaar, EPIC, ration card for Bihar voter roll revision.
