Congress chief Rahul Gandhi alleged that people in the NDA government had prior knowledge of the ‘Rs 22,000 crore’ Nirav Modi-PNB fraud and asked Prime Minister Narendra Modi to explain why the scam took place. Rahul said, ‘This Rs 22,000 crore scam cannot have been done without a high level protection. It must have been known by the people in government beforehand otherwise it is not possible. PM will have to come forward and answer questions’. Earlier this week, Punjab National Bank had disclosed that billionaire jeweller Nirav Modi had committed fraudulent transactions worth Rs 11,300 crore at one of its branches in Mumbai.
