The Congress' Delhi unit passed a "unanimous" resolution on Sunday evening asking Rahul Gandhi to return as party chief "with immediate effect". The resolution, expected to trigger a series of similar declarations by other state units, comes days after the party said organisational polls would be held in June - after Assembly elections in several key states, including Bengal and Tamil Nadu. That announcement came after a tempestuous meeting of the CWC (Congress Working Committee) - the party's highest decision-making body.
