New Delhi, Feb 12 (IANS): The BJP Tuesday attacked the UPA government over the revelations that the chief prosecutor of tne CBI in the 2G spectrum case had allegedly discussed prosecution strategy with one of the accused. The party demanded a probe.

The CBI Monday removed A.K. Singh, its chief prosecutor in the 2G spectrum case, after he was allegedly found to have discussed the prosecution strategy with one of the accused. The CBI possesses an audio recording with the suspected voices of Singh and one of the accused.

Bharatiya Janata Party (BJP) spokesperson Prakash Javadekar said that the revelations were "absolutely atrocious" and accused the Congress-led United Progressive Alliance (UPA) government of misusing the Central Bureau of Investigation (CBI).

"It is yet another proof of how CBI was abused, misused by the Congress-led government," Javadekar said. He said the government uses prosecution wing "when it cannot manipulate investigation".

The 2G case is currently under trial before a special CBI court here.

He said the BJP had demanded that the appointment of advocate on panel of the CBI's prosecution wing should be cleared by Lokpal but the government "wants to retain power to manipulate".

"Why is the Congress so silent now? The government should tell what it was doing. There should be an investigation," Javadekar said.

The investigating agency decided to remove Singh after it found an audio recording allegedly carrying a conversation between Singh and one of the accused in the case.

The agency has also registered a preliminary inquiry.

The main accused, former union minister A. Raja, Unitech managing director (MD) Sanjay Chandra and 12 others, including DMK leader Kanimozhi, have been examined by the prosecution. Cross-examination of the accused and witnesses is now on.
