New Delhi, Jan 12 (Agencies): The high decibel attack on the CAG by Telecom Minister Kapil Sibal and Congress spokesman Manish Tewari was on Wednesday countered by the PAC and the government auditor which termed such a campaign as "improper" and one that could be contempt of the House.

The PAC, which met on Wednesday, considered the remarks of Sibal and Tewari in the context of its report on the 2G spectrum allocation and the sense of the members was that these were an attack on the dignity of the two constitutional organs.

At the PAC meeting an attempt was made by a senior Congress member to distance the party from the remarks by the two were not the stand of the organisation.

But Chairman Murli Manohar Joshi produced a CD containing critical remarks of Sibal in television interviews almost suggesting that the "leak" of the report on 2G spectrum scam was from the CAG and statements of Tewari, sources said.

"The sense of the PAC was that Sibal's remarks were improper, against propriety and an attack on the dignity of PAC and CAG," Joshi told reporters here.

At a press conference last week, Sibal had described as "utterly erroneous and without any basis" the estimated loss of Rs 1.76 lakh crore arrived at by the CAG on account of allocation of 2G spectrum to telecom operators.

Joshi said the forum of the Committee was available to the minister to make any observation or suggestion on the report of the Comptroller and Auditor General (CAG) on alleged irregularities in the 2G spectrum allocations.

Contesting Sibal's remarks, Joshi said CAG had never said that its estimates on presumptive losses to the exchequer were final.

"The CAG had only mentioned three different figures based on three different models to calculate the presumptive loss. It had never said the report was final," he said.

He said the PAC would consider steps that were necessary to avoid repeat of such incidents.

In reply to a question, Joshi said there was no suggestion or proposal before the Committee today to call Sibal for seeking clarification on his remarks.

The CAG also came out with a statement, second in three days, describing Sibal's comments as "highly improper".
