Government records show that it was Mahesh Nagar who helped Vadra with the deals in Bikaner, in which his companies acquired hundreds of acres of land.
He even signed the documents as Vadra had given him power of attorney.
A recent The Times of India report quoted sale deeds from March 2008 which showed Gurgaon resident HL Pahwa selling his land for Rs 36.9 lakh to a buyer named, "Robert Vadra through Mahesh Nagar".
Clearly, Vadra had vested some authority with Nagar.
Pahwa, himself, was a director in one of Vadra's companies.
Exactly how much land Nagar helped Vadra acquire in Haryana and Rajasthan is not known but sources claim it runs into hundreds of acres, the report said.
Nagar's brother, Lalit, is a member of the Haryana Pradesh Congress Committee and, it is alleged, was rewarded with a Congress ticket in the 2009 polls overlooking the claims of many senior candidates with decades of experience.
Though Nagar lost by a thin margin, he has continued to rise in Haryana Congress as "Vadra's man".
