"If the Prime Minister or a Chief Minister is changed merely because of the ruckus created by the opposition, would democracy be able to function? I appeal to BJP to stop pressing for PM's resignation and discuss the issue in the House as per Parliamentary traditions," Digvijay said while speaking at the Indore Press Club here.
The Congress leader alleged BJP was trying to derive political mileage by "misleading the people" on the alleged scam.
The Centre allocated coal blocks on the recommendations of state governments, he said.
He claimed the UPA government wanted auction of coal mines, whereas the governments of Rajasthan, Jharkhand, Madhya Pradesh and Chhattisgarh had opposed it, saying it would make power costlier.
Digvijay also alleged that BJP government in Chhattisgarh had allocated a coal block to a company of Rajya Sabha MP Ajay Sancheti, providing him with undue benefit.
