"No options" is how a senior Congress leader responded when asked to assess DMK's choices after arrest of party supremo M Karunanidhi's daughter Kanimozhi. A fit of pique will deepen the southern party's alienation and its best bet is to stick to its perch at the Centre, he said firmly. Kanimozhi's arrest and subsequent journey to Tihar as an accused in the 2G scam is not an unanticipated development for DMK and the party was resigned to the eventuality.
