Congress' Digvijaya Singh on Saturday criticised the BJP following a report by Hindenburg Research, which accused Gautam Adani-led companies of fraud. "Whosoever is close to PM Narendra Modi and Amit Shah gets benefits...tax rates are increased and decreased for their profit," Singh said. "Same is being done for Gautam Adani...Rahul Gandhi [had] said Adani's wealth bubble will burst," he added.
