With less than three months left for the Himachal Pradesh assembly elections, the Congress is making every effort to end the turf war between former chief minister Virbhadra Singh and Union commerce minister Anand Sharma to present a united front in the polls. Singh, who recently resigned from all posts related to the elections, including chairman of the campaign committee, in protest against his marginalisation in the state, will be in the Capital on Friday at the behest of the central leadership.
