The Congress on Sunday stepped up its attack on the Centre over allegations against the Adani group, alleging that the Modi government's "loud silence" over the issue "smacks of collusion".
Adani group stocks have taken a beating on the bourses after US-based activist short-seller Hindenburg Research made a litany of allegations, including fraudulent transactions and share price manipulation at the Gautam Adani-led group.
In a statement, Congress General Secretary (Communications) Jairam Ramesh said that starting Sunday the Congress will pose three questions a day to Prime Minister Narendra Modi over the issue.
He said that amid the allegations against the Adani Group, the Modi government has maintained a "loud silence which smacks of collusion".
Ramesh said that in a response to the Panama Papers expose on April 4, 2016, the Ministry of Finance had announced that Modi had personally directed a multi-agency investigative group to monitor financial flows to and from offshore tax havens.
