The swap at the top in the finance ministry which saw the controversial Revenue Secretary R. S. Gujral— architect of the retrospective tax on Vodafone and GAAR— switch departments with Expenditure Secretary Sumit Bose was just the first of many changes in personnel planned by P. Chidambaram. He has, since, divested Joint Secretary Rajesh Khullar of the Foreign Investment Promotion Board charge. He also sent out questionnaires to several officials of the rank of deputy secretary and above asking tough questions of their ability and desire to serve in the finance ministry. Chidambaram means business and is determined to build his own team. Officials from the previous regime are naturally looking elsewhere. One such official, Thomas Mathew, joint secretary of the crucial Capital Markets division, is on his way to Rashtrapati Bhavan.
