"If they (Hazare, Ramdev) are really serious about fighting corruption, they should say something about the manner, in which, the two businessmen had become rich during the eight years of the BJP rule in Madhya Pradesh," he said during a press conference.
The I-T officials had last week conducted searches at the premises of builder and road contractor Dilip Suryavanshi and mining contractor and VNS Group of Institutions director Sudhir Sharma.
The Congress leader alleged that there were pictures showing Suryavanshi and Sharma with Ramdev. "Therefore, he (Ramdev) must say something about the recent raids," Singh said.
He criticised Chief Minister Shivraj Singh Chouhan for maintaining "silence" on the issue.
"During the raids, the I-T department recovered government files and note-sheets from the residences of two businessmen. This has exposed the true face of the Chouhan government as now everyone knows who was actually running it," he alleged.
Singh said Congress had put up hoardings in the city questioning Chouhan's alleged "ties" with the two businessmen. "However, the administration removed these hoardings much before Chouhan returned to the state capital from his foreign tour," he said.
"But time will come when Chouhan will have to answer all the questions," the Congress leader said.
