"The agency has suffered a credibility gap in the past ten years. The CBI as an organization is substantially controlled by its directors. The directors were chosen by the Government and not by any balanced collegiums," he said.
These directors were controlled not only by the government, but even by key functionaries of the ruling party, he added.
"There were several cases in which persons close to the government had to be helped", Jaitley opined.
"Similarly, there were cases where persons opposed to the government had to be victimized. Some of the charge sheets filed against the BJP in Rajasthan and Gujarat are unsustainable," he added.
Delhi is full of rumours these days about the disclosures made by a prominent businessman who acted as a front for many politicians and officials, he said adding that these were further likely to erode the credibility of CBI since prominent names connected with the CBI are also mentioned in this regard.
"A full public disclosure of this information is now necessary. Everybody must be honest. Certainly the CBI officials must be more honest than the others," he said.
He complimented former West Bengal's Governor for his comments on the investigative agency.
"Gopal Gandhi was invited to deliver the D P Kohli Memorial lecture which is annually organized by the CBI. After analyzing the statutory scheme of functioning of the CBI, Gandhi linked the CBI to the dirty tricks department of the Government. This should shake the conscious of the officials of the CBI", Jaitley said.
Talking about Narendra Modi's campaign, he said, "Modi was declared as BJP's prime ministerial candidate on September 13, 2013. Since then, he has singularly addressed 380 rallies in the country. Most of these rallies have been attended by several lakhs of people.
I had initially thought that fatigue would set in after an initial enthusiasm. That does not seem to be happening. Additionally, there have been at least 300 rallies in the 3D format which he has already addressed. Another 300 are likely to be addressed by him. I do not remember if any single individual has undertaken personal campaign of this magnitude in the recent history," he said.
