Union Minister Ravi Shankar Prasad today blamed the Congress for worsening India's crisis of bank debt. He said the UPA government did not follow the rule book during its tenure. "Under the so called economist then Prime Minister Manmohan Singh, the entire banking system went haywire due to all kinds of interference with it," he said during a press conference. The minister also claimed banking scams like the Nirav Modi case took place during the Congress rule. Mr Prasad also attacked P Chidambaram on UPA's gold import scheme. "On May 16, 2014, an order was passed by the then Finance Minister to provide benefits to seven private companies. Gitanjali was one of the seven companies," he said.
