In his book '2G Sage Unfolds', Raja slammed the then CAG Vinod Rai saying the office of the Comptroller and Auditor General was "severely compromised" by Rai who had "ulterior motives" in over-reaching his constitutional function while auditing accounts relating to the 2G spectrum allocation.
Raja claimed that he had got Manmohan Singh's "approval to go ahead" for allocating 2G telecom spectrum to new players after he explained the whole process and that there was enough spectrum available.
"The UPA government's and even more so Dr Manmohan Singh's palpable silence in relation to defending my wholly justified actions" was like "silencing of our nation's collective conscience".
Raja also claimed that the former prime minister did not have any clue about the CBI raids with regard to the spectrum allocation.

"On October 22, 2009 (after CBI raided telecom ministry and offices of some telecom operators) I met the Prime Minister in his office in South Block at around 7.00 pm. T.K.A. Nair (the then principal secretary in the PMO) was also present. People will find it hard to believe that the PM was quite surprised when I told him about the CBI raids," he wrote.
"It is my conviction consequent to the trial proceedings that there was political motivation to kill UPA 2 and Vinod Rai's was the shoulder on which the gun was placed," he wrote.
Last month, a special court had acquitted Raja and all other accused on charges of corruption and cheating in the sale of airwave licences in 2008 that derailed the-then Manmohan Singh-led government.
While CAG put presumptive loss in allocation of spectrum at Rs 1.76 lakh crore, the scam had led to Supreme Court cancelling 122 licences sold to companies.
Telecom lobbies were dead against giving licences to new players and just when the policy draft was in its final stages, a letter from the Prime Minister's Office was received, the content of which matched the business interests of the lobbies, he said.
"It is still a puzzle to me as to what could have prompted the PM to send that letter to me. With all due respect, I came of the opinion that such a letter bearing the PM's signature should never have been sent.
He goes on to state that "It seemed he (Singh) had been led to believe that there was something amiss in the functioning of my ministry."
Slamming Rai, Raja wrote the former CAG behaved like "a cat that shuts its eyes and then declares the universe is dark."
"He (Rai) had to foist his personal (or influenced) agenda by sensationalising information and creating the appearance of procedural lapses and financial misappropriation. His presumptive loss figure of Rs 1.76 lakh crore has been subsequently debunked, but it became engraved in public memory and led to my tribulations," Raja wrote.
"Vinod Rai had the temerity to dub himself the 'Nation's Conscience Keeper' on the cover of his book titled 'Not just an Accountant' in which he dedicated a few chapters on the 2G spectrum allocation.
"He in his role as CAG was the 'sutradhaar' who created the devious apparition which the media and political opposition followed," he wrote.
Stating that a "conspiracy-nexus" cannot be ruled out, Rai's words and actions were "malicious vigilantism" and "disgraceful purchase of self-promotion".
Having written his book while the 2G trial was still going on, Raja demands that Rai "be called as a witness in the criminal case filed against me so that my defence has the opportunity to cross-examine and legally challenge him."
"It would perhaps have been in the public's better interest to investigate Rai's motivation to rush into this 'hunt' while almost blatantly ignoring the decisions and recommendations of TRAI, the Union Cabinet and the Telecom Commission! Even after TRAI's explanations refuted the views expressed in the CAG's report, Rai was not willing to correct his stand. It is ironic that such a person lays claim to the badge of 'Nations Conscience Keeper'," he added.
