India's foreign ministry said on Friday that bribery allegations against billionaire Gautam Adani is a legal issue between private firms and the U.S. Department of Justice and that New Delhi has not received any request on this case from Washington.

India’s opposition is protesting the government’s silence over allegations against billionaire Gautam Adani, who was recently indicted in the U.S. for alleged fraud and a scheme to pay bribes.

Even these projects, all part of India’s Adani Group, barely convey the scale of a conglomerate so intertwined with government priorities that it is almost synonymous with Prime Minister Narendra Modi’s India.
