The Congress on Tuesday alleged that Gautam Adani`s elder brother Vinod Adani has a "central role" in the Adani Group and asked whether India`s "all-powerful agencies" will investigate allegations of "round-tripping and money-laundering" by offshore shell companies connected to their family.

Posing a set of three questions to Prime Minister Narendra Modi as part of the party`s "Hum Adani ke Hain Kaun" series, Congress general secretary Jairam Ramesh said in its January 29 response to "serious allegations" against Gautam Adani`s elder brother Vinod Adani, the Adani Group had tried to distance itself stating that he does not hold any managerial position in any Adani listed entities or their subsidiaries and has no role in their day-to-day affairs.
