Kanimozhi, the daughter of DMK Chief M Karunanidhi, was named by the CBI as a co-conspirator with A Raja in the 2G scam. However, Mr Karunanidhi's wife, Dayalu Ammal, does not feature in the new chargesheet. The concession, sources say, is a result of political pressure. Skeptics wonder why Dayalu Ammal with 60% share in Kalaignar TV, which is accused of receiving kickbacks, is not named?
