The functioning of both the ministries is "transparent" and aimed at disseminating more information to people, Gadkari told PTI.
"Our Ministry is fully transparent. Any one can see it. We don't indulge in wrong practices. There is zero corruption in our Ministries. We have nothing to hide, rather we want to provide information," he said, adding that no work contract was awarded by the concerned ministries without any tender or e-tender.
He, however, said that let the enquiry into leakage of Petroleum Ministry's confidential documents be complete, adding that some people indulge in such kind of activities.
A total of 12 people have been arrested in the case so far.
