Rajya Sabha Chairman M Venkaiah Naidu called this session of Rajya Sabha as the 'most productive' in nearly two decades. '32 bills were passed in 35 sittings. This session is the best in the last 17 years,' he said. Before adjourning sine die, the lawmakers cutting across party lines observed a minute of silence to mourn the demise of former foreign minister Sushma Swaraj.
