BJP spokesperson Nirmala Sitharaman on Tuesday said the party endorses party chief Nitin Gadkari's stand that he was open to investigation by a competent authority. She questioned the reason behind Congress “running away” from probing allegations against others like Virbhadra Singh and Robert Vadra.

Congress leader Digvijaya Singh has written a letter to PM Manmohan Singh, seeking an investigation into the dealings of Gadkari's company.

Congress had its own quota of problems, with Virbhadra Singh, the top contender for the CM's post in Himachal Pradesh, being accused of forgery, money-laundering, corruption and Income Tax evasion.

However, Gadkari faced heat from some quarters within the party, including MP Ram Jethmalani – who asked Gadkari not to seek a second term in the wake of graft allegations against him.

“In the interest of the party, in his own interest, he (Gadkari) should get out of the fray, and he must give the position to somebody who inspires greater confidence,” he said.
