Who is the proactive CAG in India serving?

Who is the proactive CAG in India serving? Is he serving BJP or the country? His 1.76 crore scandal by A.K.Raja and company is already being debated. Now the coal mining alleged scam to the tune of Rs. ……directly making the Prime Minister responsible is baffling all of us. The Supreme Court very recently directed the union government to adhere to auction the natural resources to do away the major loss to the nation. Why it was not adopted in the past? Who will answer it? A common sense says, it had to be done by auction .For this one needs not go to Oxford University.

Let the CAG come forward with his formula in public which gave him this figure .Is not his calculation laden with ulterior motives and is more an academic exercise far from truth. The country is moving to a very chaotic situation by such indulgence.
