Aam Aadmi Party chief Arvind Kejriwal has promised Punjab a big incentive for votes in the coming assembly elections -- 24-hour electricity, 300 units free for each family and a waiver on previous power bills. Pointing to Delhi, where he made similar promises ahead of polls, Mr Kejriwal said, "This is Kejriwal's promise, not Captain's vows. We deliver our promises. Captain's promises haven't been fulfilled even after 5 years".
