Congress' Rashid Alvi has reacted after ex-Union Minister P Chidambaram said that Operation Blue Star was "the wrong way", adding that then PM Indira Gandhi "paid with her life for that mistake". Alvi asked, "Chidambaram ji's attacks on...Congress...are raising doubts." "Criminal cases against him are still pending. I wonder if he's under any pressure to continue attacking...Congress," he added.
