The Congress on Tuesday accused Union Minister Ananth Kumar and former Karnataka Chief Minister B.S. Yeddyurappa of misuse of power and public office and demanded action against the duo.Congress leader Randeep Surjewala released a video clip of a purported conversation between Ananth Kumar and Yeddyurappa -- both senior BJP leaders -- regarding collection and payment of money by them and a diary seized by the Enforcement Directorate containing sensitive information against certain Congress leaders."The video of the shameful and sinful conversation dated February 12 between these leaders took place during a Bengaluru meeting of the Bharatiya Janata Party. It reveals blatant misuse of political power and public office," Surjewala told the media here."The 125 crore Indians want to know where that money came from and how it was used. (Prime Minister Narendra) Modi-ji talks about fighting black money. Is it not a case fit for invoking the Prevention of Corruption Act?" he said.Surjewala said the central government was misusing the ED, Central Bureau of Investigation and the Income Tax Department against political rivals in anticipation of defeat in the assembly elections in the five states.
