New Delhi: The trouble for BJP President Nitin Gadkari is more within than outside. One after the other, senior party MP's have sought his resignation in the wake of allegations against Gadkari's Purti Group. And the latest ones alluding that Gadkari's wife and sons held shares in three Purti shell companies, attempt to debunk the clean chit by RSS ideologue S Gurumurthy on the basis of whose in-house investigation. The BJP and the RSS have so far stood by the party president.
