The 2G spectrum scandal in India involved government officials undercharging mobile companies for licenses to use radio frequencies. This resulted in an estimated loss of 1.76 lakh crore (1.763 trillion) rupees to the Indian exchequer. Key politicians like A. Raja and Kanimozhi, bureaucrats, corporate executives from companies like Reliance and Essar, and journalists were implicated in the scandal. The scandal broke due to investigations into corporate lobbyist Nira Radia's phone conversations and revealed collusion between politicians, corporations and media figures.
