"CBI is an autonomous body and the Centre cannot give any direction to it. We can only request them to speed up the probe as many cases are pending," he told a meet-the-press organised here.
"We can tell CBI to speed up the matter. We cannot ask them to place the report by a particular time. That is not possible," Gowda, a senior BJP leader, said on Congress questioning what the NDA government was doing in the last two years.
He also made it clear that government did not want to name any person without a conclusive proof.
"I do not want to make any statement against anybody...Unless I get conclusive proof," he said when asked whether former defence minister A K Antony was linked to the issue.
The "conclusive" evidence would come when CBI files its report, he said.
