According to sources, Sonia Gandhi is all set to step down as the interim chief of Congress party. The Congress Working Committee meeting is scheduled for Monday and ahead of the meeting the party was divided into two fractions. Some Congress leaders are demanding collective leadership while another group has sought the return of Rahul Gandhi as the president. Some Congress leaders have called for bringing changes in the organization by effecting reforms through decentralisation of power and empowerment of state units besides setting up of the central Parliamentary Board, a body that existed in the party in the 1970s but was later wound up.
