DMK MP Kanimozhi Karunanidhi is now known by the company she keeps - former telecom minister and 2G pawn A Raja is a close friend, Rajathiammal, Niira Radia's DMK conduit, is her mother and Tamil Maiyam, the Chennai-based NGO raided by CBI this morning as part of its probe into India's largest-ever scam, lists her as a director.

Much has been speculated about the DMK's association with the scam, about her own role in getting Raja the telecom protfolio, and consequently, in the broader 2G episode. Now, there may be a thousand chinks in the link, but it is true that she remains the only visible link between a disgraced telecom minister, a scam and a raid on an NGO.

So, as the prosaic needle of suspicion swings towards her, should not she offer to resign as MP? That will be in keeping with the dignity of the public office she holds. After all, a minister had to resign on lesser grounds (remember Shashi Tharoor?)
