The AgustaWestland scam is back in the news. Air Marshal SP Tyagi became the first Armed forces Chief to be arrested by the Central Bureau of Investigation (CBI) on charges of corruption. He will be produced before a judge tomorrow and will be subjected to custodial interrogation by the CBI. Tonight Air Marshal Tyagi may have been arrested but where is the smoking gun? Who were the politicians who were the ultimate recipients of bribe money from Agusta Westland? Is there anything to suggest that senior Congress politicians were involved? We discuss on The Buck Stops Here.
