Indian Prime Minister Narendra Modi's party has "nothing to hide or be afraid of" on the controversy over the Adani group, the home minister said on Tuesday, responding to opposition allegations of favouring the conglomerate attacked by a U.S. short seller.
Led by billionaire Gautam Adani, the business house's seven listed companies bearing his name have together lost about $120 billion in market value since a Jan. 24 report by Hindenburg Research alleged improper use of offshore tax havens and stock manipulation. The Adani group has denied the allegations and threatened legal action against Hindenburg.
"The Supreme Court has taken cognisance of the matter. As a minister, if the Supreme Court is seized of the matter it is not right for me to comment," Amit Shah, widely considered the most powerful politician in India after Modi, told the ANI news agency.
"But in this, there is nothing for the BJP to hide and nothing to be afraid of," Shah added, referring to the ruling Bharatiya Janata Party (BJP).
He denied allegations of crony capitalism and suggested the opposition to go to court if they had proof.
The Adani crisis has stalled parliament, ignited street protests by the opposition, sparked off investigations by regulators and weighed on the broader markets in a challenge to Modi ahead of a string of state elections this year and general elections next year.
Rivals including the main opposition Congress party accused Modi and the BJP of longstanding ties to the apples-to-airports Adani group, going back nearly two decades from when Modi was chief minister of the western state of Gujarat. Gautam Adani and Shah also come from the same state.
Modi's immense popularity, however, appears intact for now, according to approval ratings.
Without referring to Adani, Modi told parliament last week that the "blessings of 1.4 billion people in the country are my protective cover and you can't destroy it with lies and abuses", as opposition lawmakers chanted "Adani, Adani".
Shares of Adani Enterprises ADEL.NS, the group's flagship, fell nearly 4% in early trade on Tuesday. The company, which pulled a $2.5 billion share sale earlier this month after the stock rout, will announce quarterly results later in the day.
Adani Power ADAN.NS and Adani Green Energy ADNA.NS fell too in a wider Mumbai market.NSEI was up slightly.
India's Economic Times daily reported on Tuesday that Adani group executives had been holding negotiations since last week with Abu Dhabi's International Holding Corp (IHC) for capital infusion into Adani Enterprises or other group entities.
Adani and IHC did not immediately respond to requests seeking comment.
The Adani group has appointed accountancy firm Grant Thornton for independent audits of some of its companies, Reuters reported on Monday, citing sources, even as India's market regulator said it was investigating the report by Hindenburg, as well as market activity immediately before and after the report was published.
