Indian banks are reviewing their Adani exposure and whether they need to tighten due diligence, eight bankers said on Thursday, after the group's billionaire founder Gautam Adani was indicted by U.S.

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.

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.
