Chidambaram is a south Indian name.... you seem to have mistaken it to mean "Finance Minister"... :-)
Sure there was a "Finance Minister" during BJP regime, but he was not Chidambaram.
Going by the concept of outsourcing - which states that do only your core business, and outsource whatever else you can't excel at, BJP might employ those tactics to increase the government's efficiency and effectiveness... It should be welcomed, as you have rightly done with your cheerful endorsement..
