As details tumbled about the alleged dubious funding for a company run by Gadkari, Corporate Affairs Minister M Veerappa Moily promised a probe into it.
To add to the discomfiture of BJP, party MP Ram Jethmalani demanded Gadkari's resignation, asking him not to seek a second term as party President.
Media reports have raised questions over the source of funds for Purti Power and Sugar Ltd controlled by Gadkari.
Media investigations claim that major investments and large loans to Purti were made by a construction firm Ideal Road Builders (IRB) group, which had won contracts between 1995 and 1999, when Gadkari was PWD minister in Maharashtra.
Gadkari has denied the allegations and offered himself and his companies to any probe.
Moily said the Registrars of Companies will "definitely inquire into it... We have not ordered anything. It is all coming in the newspapers. Since it has come in public domain, we told our ministry to make some discreet inquiry to find out what exactly is the matter. Are there any violations of Companies Act?"
When asked by reporters whether the business dealings of Robert Vadra, the son-in-law of Congress chief Sonia Gandhi will also be scrutinised, he said the two issues were separate and there was no link between them.
BJP accused the government of being prejudiced and selective in its approach on the probe into corruption allegations. (MORE) NAB RC AD ADS RAM AKK VSC PAL
