New Delhi, Nov 23 (ANI): The Indian Revenue Service (IRS) Association has shot off a letter to Aam Aadmi Party convener Arvind Kejriwal for his remarks that an ordinary income tax inspector makes Rs 1 crore a year and that he could also have earned crores of rupees as income-tax commissioner had he not resigned to embrace social work. The letter also says that such utterances were unnecessarily damaging the image of the fine service. The Association also refuted Kejriwal's claims that he worked as a commissioner of income tax, saying his batch has still not been promoted to that rank. Meanwhile, reacting over this Kejriwal said that this is also a conspiracy against him and he thinks the letter was sent to him on the directions of the Congress party.
