It demanded a clarification from Dr Singh after the CAG said the coal block allocations by the government had led to extending undue benefits of Rs 1.86 lakh crore to private parties.
CPI-M leader Sitaram Yechury said the PM, if he makes a statement in the Parliament, should clarify why the government did not implement its own decision of allocating coal blocks through competitive bidding and whether it would book all those responsible for giving away the blocks without bidding between 2005 and 2009.
"Depending on that clarification, we will take the next course of action. On that basis, we will take the issue forward," he had said.
Referring to the disruption of the Parliament, Yechury had said "a possible way" to break the logjam was that the PM holds talks with Leaders of Opposition of Lok Sabha and Rajya Sabha and appeals to the principal opposition BJP, saying that a discussion would follow after he makes a statement in the House.
This, he said, should be done without wasting any time and a solution should be found out before Singh leaves for NAM summit on Tuesday.
