Niira Radia is a former corporate lobbyist whose taped telephone conversations implicated her influence in the allocation of key ministries in the Government of India in 2009. Discussion of the tapes resulted in the "Radia tapes controversy", which was a media event that led to the uncovering of the alleged 2G spectrum scam involving former telecommunications minister A Raja. These events led to Raja's resignation and later acquittal by Special CBI court, and Radia's departure from corporate lobbying.
