Senior Congress leader P Chidambaram today said only the Gandhis could not be held responsible for the party's recent election defeats. Speaking to NDTV a day after a meeting of the Congress "G-23" or rebels, he urged the group not to split the party. Like many Congress leaders, Mr Chidambaram also confirmed that Sonia Gandhi had offered to step down, along with her children Rahul Gandhi and Priyanka Gandhi Vadra at the election post-mortem by the Congress Working Committee (CWC) on Sunday.
