"A number of charges have been levelled regarding the business dealings of the companies promoted by Robert Vadra. There have not been any clear answers to the questions which have been raised regarding the finances of these companies and their activities in the real estate sector," the party's Politburo said in a statement here.
The party said it was of the opinion that "these business dealings and the affairs of these companies should be investigated by the relevant authorities. Only such a probe can bring out the truth."
Activists Arvind Kejriwal and Prashant Bhushan had alleged that Vadra, Congress President Sonia Gandhi's son-in-law, had been hugely favoured by realty major DLF. Vadra has dismissed the charges as "utterly false, entirely baseless and defamatory".
