"Gadkari has expressed his willingness to face probe over allegations levelled against him. Let Congress-led UPA Government show the same seriousness in probing far more serious allegations with much more evidence against its functionaries," he told reporters here.
Kulkarni said people should wait for the truth to come out since Gadkari had expressed his willingness to face any probe on his company's fundings.
"Long before the national highway development project was conceptualised, he (Gadkari) had made the first expressway in the country as Maharashtra PWD Minister and he did it without facing any allegations of corruption," he said.
On former chief minister B S Yeddyurappa's plans to quit the BJP, Kulkarni said losing a leader like him certainly was a matter of concern for the BJP.
He noted that the senior leader was the principal contributor for the growth of BJP in Karnataka, but "unfortunately many wrongs have happened".
Party leaders should honour the aspirations of the people, who wanted good governance from the BJP.
On the demand for projecting Gujarat Chief Minister Narendra Modi as the BJP's Prime Ministerial candidate, Kulkarni said the senior party leaders would take a decision at the right time.
