A cash-for-votes scam in Telangana has taken a dramatic turn with the emergence of a tape of a phone conversation in which Andhra Pradesh chief minister Chandrababu Naidu is purportedly heard asking a legislator to back a TDP candidate in an election. The Andhra Pradesh government has denied that it is Naidu's voice on the audio tape that was first played on Sunday on T News, a Telugu news channel owned by Telangana’s ruling Telangana Rashtra Samithi (TRS) party, and later picked up by other channels.
