Raja calls on DMK chief

Former telecom minister A Raja, at the centre of the multi-crore 2G Spectrum scam, called on his mentor, DMK chief and Tamil Nadu chief minister M Karunanidhi, on Saturday.

Both were closeted for some time at the CIT colony residence of Karunanidhi.

Although party sources described the meeting as routine, it came a day after the CBI questioned Raja. Party sources, however, said Raja's continuance as a leader could cost the party dear in the assembly elections due in six months.
