The DMK landed in fresh trouble with emergence of allegations that former Aircel boss and promoter of STel, C Sivasankaran had transferred Rs 50 crore to DMK-owned Kalaignar TV. Sources said the CBI is probing if a fund flow of Rs 50 crore to Kalaignar TV from STel was a quid pro quo for the award of six licences to STel in contravention of the guidelines of the Department of Telecom. The licences to STel were granted during former Telecom Minister A Raja’s tenure.
