INDORE/BHOPAL: Controversy erupted in Madhya Pradesh on Tuesday over an alleged audio of CM Shivraj Singh Chouhan in which he purportedly says that the BJP central leadership had “decided that the Congress government in the state must fall”. Former CM Kamal Nath lashed out at BJP, saying this was proof that his government was toppled through a BJP conspiracy and not internal strife as has been claimed. “I have been saying from the very first day that BJP deliberately brought down my majority, democratically elected government through conspiracy and enticement,” Nathtweeted. Congress said it would approach Supreme Court and the President. BJP has not yet commented on the controversy.
