Bharatiya Janata Party (BJP) has retaliated by claiming to reveal the ‘cash paper trail’ in the money laundering case on Congress’ Karnataka leader D K Shivakumar. BJP spokesperson Sambit Patra said money was illegally deposited to All India Congress Committee (AICC) headquarters in Delhi in kilogrammes. “Congress has always treated Karnataka as a cash cow or an ATM which was utilised by Gandhi family,” he added.
