BJP and Left parties demanded a fair and transparent probe into the issue after Parakh said that the PM should also be an accused as he is equally responsible in coal block allocations.
"I am not surprised that the then Coal Secretary Parakh has said that the PM should be accused No. 1 in the coal scam. We are all aware of the fact that he was the Coal Minister during the period of the coal scam and every allotment of coal block has been done with his signature," BJP leader Yashwant Sinha said.
"He has spoken a little, he should come out clean now, make public statements of how files were disposed off at that time, how chits were received from Congress party headquarters and the PMO and how PMO transmitted those instructions to the Coal Ministry for allotment of coal blocks either to the favourites or to persons with whom they had struck deals," he said.
BJP Deputy Leader in Rajya Sabha Ravi Shankar Prasad said Parakh's statement "merits serious consideration" as the accountability of the PMO and the PM is equally important.
"Therefore, the accountability of the PMO and the PM is equally important. We demand a fair investigation," he said.
