The Central Bureau of Investigation (CBI) launched a probe into the allegations, and it was discovered that Singaravelan had been using a complex network of middlemen and shell companies to receive and launder the bribes. The investigation revealed that several high-ranking government officials, including bureaucrats and politicians, were involved in the scam.
The Gnanavadivel Singaravadivel fix had a significant impact on the Indian economy, both directly and indirectly. The scandal led to a significant loss of investor confidence, with several foreign investors pulling out of the telecom sector.
The scam also led to a significant change in the way telecom licenses and spectrum were allocated. The government introduced an auction-based system for spectrum allocation, which aimed to increase transparency and reduce the risk of corruption.
