Telecom Minister A Raja today termed the controversy over 2G spectrum allocation as "politically motivated" and said vested interests are behind the allegations of wrongdoings.

"No doubt it (the controversy) is politically motivated," Raja said when his response was sought to allegations of wrong doings.

His comment comes a day after the Supreme Court asked the Centre, Raja and CBI for a response in 10 days on a charge that the Centre was trying to put a lid on the investigation into the alleged Rs 70,000 crore scam in allocation of 2G telecom licence in 2008.

The petitioners in their plea before the Supreme Court had alleged that the DoT, under Raja, had given away 2G spectrum at a throwaway price of Rs 1,651 crore for pan-India licences on a first-come-first-served basis in January 2008.

Stating that the investigation related to alleged criminal conspiracy between certain public servants and private persons for grant of Unified Access Service (telecom) licences, the petitioners had claimed that certain middlemen, including a PR consultant Niira Radia, were involved in this.

Raja contended that vested interests are behind the move and is a result of the corporate war in the telecom space.

The petition was filed by the Centre for Public Interest Litigation (CPIL), NGO Telecom Watchdog and an individual.

On the issue of CBI having filed an FIR against unknown officials of the Telecom Ministry, the apex court wanted to know how the CBI was not aware of who is the subject of the investigation that has been on for several months now.

On new operators wanting to return licenses, Raja said, "In the last operators' meeting, it was highlighted...bailout may be done. It will be discussed in the Telecom Commission."

Some operators have asked the government to return the Rs 1,651 crore they forked out for a pan-India 2G licence as many of them are yet to launch services in the country.

The new operators are finding it difficult to roll out services in view of huge investments required for setting up infrastructure. Only 2-3 new operators could start their services in some of the circles.

There are, however, no clear guidelines on this issue and the DoT may consider it in the coming few days.
