Re-affirming UPA government’s commitment to strengthen the institution of CAG, he said, it is necessary to improve transparency and accountability in the work of government.Emphasising the need for accurate and balanced report by the country's top audit institution, the prime minister said CAG reports were taken very seriously by the government, parliament, media and the public at large. He said, the government is taking measures to ensure quick and timely action on CAG reports. The Prime Minister said this at a function to mark the 150 years of Comptroller and Auditor General of India in New Delhi today.In her inaugural speech, President Pratibha Devisingh Patil said, public auditors have a major challenge to respond competently to growing expectation of the stakeholders. The President emphasised that public financial accountability is essential for rooting out corruption.In a related development the CAG report on the 2G spectrum allocation indicting the former telecom minister A. Raja was tabled in Parliament today even as the opposition continued to demand a Joint Parliamentary Committee probe. The CAG in its report adds that 85 out of 122 licenses issued in 2008 were found to be given to companies, which did not satisfy basic eligibility criteria. The report further said, A Raja justified allotment of spectrum to a few new operators in 2008 without reconsidering the old entry fee discovered in 2001, ignoring the advise of the Prime Minister. The report added that the Telecom Commission was not consulted in the 2G spectrum allocation and views and concerns of the Ministry of Finance were over-ruled. The CAG holds Raja responsible on many fronts for violating guidelines, indulging in favouritism and costing the government 1.76 lakh crore rupees by mishandling the allocation of 2G spectrum in 2008.The CAG report will now be taken up by Public Accounts Committee headed by Murli Manohar Joshi of BJP, which has members from other parties too.Raja was forced to resign on Sunday night under considerable pressure from the Congress, which has been attacked in Parliament by a united Opposition for corruption.A lunch meeting called by Finance Minister Pranab Mukherjee today also ended without any solution to the impasse in Parliament over the 2G spectrum scam.
