At a time when both party president Sonia Gandhi and vice-president Rahul Gandhi are leaving no stone unturned to push Modi government to margin by raising number of emotive issues, this will prove to be a big setback for them. Reportedly, CBI has arrested party MLA Anil Lad for allegedly exporting iron ore illegally from Belikere port. The agency has been investigating the case on a Supreme Court order which had appointed the Central Empowered Committee into the issue. The illegal export of iron ore from Belikeri port in Karnataka's Uttara Kannada district was exposed by former Lokayukta N Santosh Hegde, who in his report had said that 7.74 million tonnes of iron ore were illegally exported between 2006-2007 and 2010-11, causing huge loss to the exchequer.
