The Congress core group met in New Delhi on Tuesday ahead of the tabling of the standing committee report in the Parliament on coal block allocations.
The standing committee was headed by Trinamool Congress MP Kalyan Banerjee.
The Comptroller and Auditor General of India (CAG) report on coal block allocations, tabled in the Parliament on August 17, 2012, had put the United Progressive Alliance (UPA) government in a spot and the opposition stalled House business for many days.
The final CAG report lowered the estimated windfall gains to Rs 1.86 lakh crore by excluding the state-run companies and joint ventures with government entities.
The coal ministry had argued for separating allocations to private companies on the ground that state entities or their joint ventures were in any case audited separately by the CAG.
The standing committee's report is coming at a time when the opposition has once again raked up the coal block allocation issue.
