evidence: Adani Group denied allegations levelled by Rajya Sabha MP Subramanian Swamy claiming that the corporate group has outstanding loans to the tune of Rs 4.5 lakh crore. The ports-to-energy conglomerate claimed in a tweet that it has maintained "an impeccable record of not a single NPA" in its 30-year-long history. [...] Swamy, on Friday, had tweeted: "Trapeze Artist Adani now owes Rs. 4.5 lakh crore as NPA to banks. Correct me if I am wrong. Yet his wealth is doubling every two years since 2016. Why can't he repay the banks? May be like with the six airports he has bought he might soon buy out all the banks he owes money."
