Priyanka Gandhi Vadra's attack on Prime Minister Narendra Modi on Thursday included a not-so-subtle dig at mega film star Amitabh Bachchan, who was once one of her father Rajiv Gandhi's closest friends. The Congress leader made the comments in Uttar Pradesh on the last day of an acrimonious campaign for the marathon national election. "You must understand that you have made the world's biggest actor your Prime Minister. You might as well have chosen Amitabh Bachchan as PM. No one would anyway do anything for you," Priyanka Gandhi said in Mirzapur.
