The main opposition Congress party has accused Modi and his Bharatiya Janata Party (BJP) of shielding Adani and stonewalling independent investigations into his dealings in the country, charges the ruling party has denied. Congress workers have also held street protests demanding a parliamentary probe.

Adani, 62, one of Asia’s richest men, was thrust into the spotlight last week when U.S. prosecutors in New York charged him and seven of his associates with securities fraud.

The U.S. case against Adani won’t help Prime Minister Narendra Modi’s ambition to leap forward as a global manufacturing power, in part by attracting foreign direct investment.
