The Aam Aadmi Party headquarters in Delhi is buzzing as people walk into the "swaraj kaksh" or the room for self-rule, the name given to reception area of the campaign office. On entering, you come across TN Panchapakasan or TPN as he is fondly called here. Till four months ago, TPN was the chief operating officer at one of India's leading BPOs. He quit to work as an AAP volunteer and is now a key member of the party's legal and media outreach team.
