It's the end of an era for Pranab Mukherjee, who submitted his resignation from the post of Finance minister. He stepped down from active politics after four decades. Pranab will now file his nomination for Presidential elections on June 28. On NDTV’s show We Mean Business, Yashwant Sinha, Senior Leader, BJP & Former Finance Minister said that he considers Pranab to be a resounding failure. "He was an FM for 4 years and in 4 years, he could do little to meet the challenges, which could easily be anticipated but he put the blame on global crisis and on Greece," said Sinha.
