New Delhi: Supreme Court’s strict vigil over the Central Bureau of Investigation (CBI) also could not stop the premier agency from favouring DMK patriarch Karunanidhi’s family.

CBI on Friday filed its first chargesheet against former Telecom Minister A Raja and his aide Siddharth Behura, in the 2G spectrum allocation scam, but excluded Karunanidhi’s family from it.

CBI’s this step ahead of the Tamil Nadu Assembly elections has been considered by many as a decision influenced by politics. The chargesheet does not include Karunanidhi’s daughter Kanimozhi’s company, Kalaignar channel, which received Rs 214 cr from DB Reality, a firm owned by Balwa.

According to sources, CBI had enough evidence to file a chargesheet and prove that Kalaignar TV was bribed for Rs 214 cr by Shahid Balwa of the 2G Spectrum allocation scam.

It was evident that if the chargesheet would have been filed, it would have tightened the noose around Karunanidhi’s family and they might even have been barred from contesting the polls.

However, CBI defended its decision by saying that they will continue their investigations and that a supplementary chargesheet would be filed after the state elections, which will conclude on April 13.

Noticeably, Karunanidhi’s daughter Kanimozhi and his wife Dayalu have 80 per cent ownership rights in the Kalaignar TV.
