"We will supply Niira Radia's tape by July 12," CBI prosecutor A K Singh told Special CBI Judge O P Saini.
The agency told the court that it will also be supplying some additional documents to the accused on July 12.
The development comes in the wake of some of the accused submitting to the court that the CBI was not providing them the transcripts of Radia's conversation, despite she having been made a key prosecution witness in the case with her statements to the CBI often referring to those conversations.
Swan Telecom Pvt Ltd, named as an accused in the scam, had yesterday told the court that the CBI should supply to them all the documents, which it has filed in the court along with the charge sheet, so that they could respond.
The counsel for other accused also pointed out to the court that the CBI is withholding from them some of the documents which they have filed in the court.
The CBI, however, had countered these allegations saying there are some documents on which they have not relied upon and thus the accused were not supplied the copies of such documents.
