He maintained that the CAG report on coal block allocation should have been discussed in Parliament and Public Accounts Committee but the Opposition chose to cause disruptions.
"We have just ended a wasted session of Parliament. Both the Houses were paralysed because CAG has issued a report which rightly or wrongly has certain allegations about public functionaries," Singh told reporters outside Parliament shortly after the end of Monsoon Session.
"We have great respect for the institution of CAG, but if we do respect this institution, we must be willing to debate its finding in PAC or even on the floor of Parliament which we have always been willing," he said.
Without naming BJP, Singh said, "The Opposition chose not to take advantage of the subtle institutional practices dealing with the reports of CAG and insisted on disrupting Parliament. This is negation of democracy."
He warned that "If this thought process is allowed to gain momentum it will be a grave violation of Parliamentary politics as we have understood."
Parliament could work only on six out of 19 days of sittings because of BJP's unrelenting demands for resignation of the Prime Minister over the coal block allocation issue besides cancellation of allotments and setting up of independent inquiry. (MORE)
