The request of the investigating agency to probe the role of Gupta was earlier turned down by the Government but now the CBI sources said Corporate Affairs Ministry has given the go ahead to the agency to quiz him.
The Ministry had refused to grant him permission even as the CBI reasoned out that his questioning was important as he was the Secretary between 2006 to 2009, a period which has come under the scanner.
"There has been a crisis of confidence as far as CBI functioning is concerned. Earlier, attempts were made by the government to interfere in its affairs when the Law Minister was found tampering with the status report on Coalgate... Now it has denied permission to CBI to question Mr Gupta," BJP spokesperson Abhimanyu had said.
When contacted over phone, Gupta said he would not like to speak on the matter.
