There is a growing clamour within the Punjab Congress over the need to declare a chief ministerial candidate for next month's assembly polls, with many senior leaders throwing their weight behind Charanjit Singh Channi, the state’s first chief minister from the scheduled caste community. Though the Congress high command has so far maintained that the party will fight the February 20 elections to the 117-member assembly under a "collective leadership", many leaders in its state unit are seeking that the air surrounding the issue be cleared at the earliest.
