He called for the removal of merchant discount rate (MDR) charges on UPI transactions and demanded the arrest of MCD Commissioner Sanjeev Khirwar in connection with the Satya Niketan building collapse.The remarks came as the E20 debate continues to generate public discussion over the use of ethanol-blended petrol and its impact on motorists.Poonawalla’s claim of detention and his allegations against the authorities could not be independently verified by The Tribune.
