The Congress has drawn up a list of 40 star campaigners, including party president Sonia Gandhi, vice-president Rahul Gandhi and former PM Manmohan Singh, to join the Punjab leadership for canvassing. Ex-cricketer Azharuddin and actor Sonu Sood too would be campaigning for the party in the Assembly polls, slated for February 4, a statement from the Punjab Congress president’s media cell said on Thursday. Punjab Congress president Capt. Amarinder Singh is already leading the election campaign.
