The Leader of Opposition in Rajya Sabha also charged the government with "interference in the administration of justice" by not allowing CBI to acquaint the apex court with the full truth.
"CBI cannot find out the truth and even if some honest officer in the CBI tries to find out the truth, the UPA is a rogue government which will not allow it to operate independently," Jaitley told reporters here.
"This is a very serious matter. This is evidence of the government's pressure on the CBI to save the prime minister," Swaraj said on Twitter.
Jaitley said the UPA is interested in "diluting the guilt of the culprits" and does not want the truth to come out.

"When Ministers, civil servants and officials try that the Supreme Court should not be acquainted with the full truth. This is an interference in the administration of justice. The government owes and explanation," the BJP leader said, while demanding that the CBI's original unaltered report be made public besides being placed before the Supreme Court.
"These facts now conclusively show that CBI will not be honestly allowed to investigate this case and therefore, the system will have to seriously consider whether an SIT must take over the administration and investigation of the coal scam. The Coal scam should be handed over to a SIT instead for the truth to come," Jaitley said.
