Amid cries of "shame-shame" and "pradhan mantri jawab do", Leader of the Opposition in Lok Sabha Sushma Swaraj raised the issue and said the Prime Minister should come to the House and assure members that the CBI probe will not be hampered due to the missing files.
She said as the Prime Minister had recently taken full responsibility in the Lok Sabha, it was incumbent upon him to take the House into confidence as to what had happened to the 147 missing files.
Swaraj wanted the Speaker to direct the Prime Minister to come to the House and make a statement. Singh had held the coal portfolio from 2006 to 2009 when the coal blocks were allocated.
Rajya Sabha also witnessed uproar after which Coal Minister Sriprakash Jaiswal made a statement saying that a committee has been constituted to go into the issue of missing files which has held two meetings.

"I would like to assure the House that my ministry would leave no stone unturned in tracing and providing the documents sought by the CBI," he said.
But, the opposition was not satisfied with the statement with Leader of the Opposition Arun Jaitley finding loopholes asking whether any FIR has been lodged by the Coal Ministry about missing files.
The uproar led to adjournment of Lok Sabha till 1 PM and Rajya Sabha till 2 PM.
