New Delhi, Jan 15 (ANI): Reaffirming its allegations against Bharatiya Janata Party's Delhi chief Satish Upadhyay over power discoms, the Aam Aadmi Party (AAP) on Thursday said that it has enough evidence to prove the same. Earlier on Wednesday, Upadhyay had threatened to sue Kejriwal over power discom allegations. Kejriwal has alleged that the former's companies had supplied electric meters to Anil Ambani-group controlled power utility BSES and that the party was soft on discoms indulging in corruption.
