New Delhi: PM Manmohan Singh disputed the estimates of huge loss from the spectrum swindle by citing the subsidies given to the poor on food and kerosene in his interaction with the media on Wednesday. Responding to a question on whether he agreed with telecom minister Kapil Sibal that there was zero revenue loss on 2G, he said there could be no opinion on such an issue, stressing that many consider the amount spent on subsidies on food and kerosene as loss.
