NEW DELHI, MAR 22 (AP/UNB) - India's Parliament is in an uproar over a report by government auditors that the country lost nearly $210 billion in revenue by selling off coalfields to private and state-run companies without competitive bidding.

Outraged opposition party leaders demanded an explanation Thursday from Prime Minister Manmohan Singh after the report was leaked to The Times of India newspaper.

Singh's government has been repeatedly embarrassed as senior ministers and officials face corruption charges stemming from the hosting of the 2010 Commonwealth Games and the sale of cellphone spectrum that auditors said lost the country billions of dollars.
