BJP President Nitin Gadkari on Monday dragged Congress General Secretary Digvijaya Singh to the court by filing a criminal defamation case against him at a Delhi's court. The BJP president hit out at Digvijaya Singh who had said that Gadakri along with his business partner Ajay Sancheti had made a profit of 490 crore from the Chhattisgarh coal mines. Gadkari argued before Metropolitan Magistrate Sudesh Kumar that Singh's comments had maligned his reputation.
