The 2G spectrum scam involved the Indian government undervaluing 2G spectrum licenses auctioned in 2008, resulting in an estimated loss of ₹1.76 lakh crore to the exchequer. Former telecom minister A. Raja was accused of undervaluing spectrum and ignoring ministry recommendations to benefit companies like Swan Telecom, Unitech Wireless, and Reliance Communications. A 2010 CAG report estimated the loss and criticized Raja and the TRAI. After public pressure, Raja resigned and was later arrested along with other officials on corruption charges. The scandal impacted many political, corporate, and media figures and continues to be a topic of political debate in India.
