The questions included those on coal policy and allocation of coal blocks when the Prime Minister was in-charge of the Coal Ministry between 2006 and 2009.
Nair’s reply was sought on delay in auctioning of coal blocks, missing coal files and events leading to Talabira coal block being given to Hindalco in which the CBI has registered a case against then coal secretary P C Parakh and Aditya Birla Group chairman Kumar Mangalam Birla.
The CBI would now be informing the Supreme Court about the reply sent by Nair.
The agency has already examined two former PMO officials, Vini Mahajan and Ashish Gupta, who were posted in the PMO between 2006 and 2009.
Mahajan, a 1987-batch IAS officer from Punjab cadre, was a Director with the PMO during the period and has now been repatriated back to the state where she is Principal Secretary level officer.
Gupta, an IPS-officer of 1989-batch from Uttar Pradesh cadre, who was the vigilance officer in the PMO, has also gone back to his cadre.
