2G spectrum case
The 2G spectrum case was a political controversy in which politicians and private officials of the United Progressive Alliance (UPA) coalition government in India were allegedly involved in selling or allotting 122 2G spectrum licenses on conditions that provided an advantage to specific telecom operators. A. Raja, then Telecom Minister, was accused of selling 2G spectrum licenses at a very low cost which resulted in the loss of ₹1,760 billion (US$25 billion) in government revenue.
