New Delhi: Congress leader Rahul Gandhi today urged "the opposition and all parties", to help pass the Lokpal Bill in Parliament, a day after ally Mulayam Singh's Samajwadi Party warned the government against pushing the proposed anti-corruption law. "This is a matter of national importance. We would like all parties to put aside small differences and do this job," Mr Gandhi said at a press conference, flanked by union ministers P Chidambaram and Kapil Sibal.
