The party has retained 2G scam-tainted former union minister A. Raja and former union textiles minister Dayanidhi Maran as its candidates. They will contest from Nilgiri and Central Chennai constituencies.
Asked about the cases against them, Karunanidhi said the cases filed against them were now "shaky" and the situation was such that there were no witnesses to prove the charges.
The other sitting Lok Sabha members of the DMK who have been retained are T.R. Baalu, T.K.S. Elangovan, S. Jagathrakshakan, R. Thamaraiselvan, S. Gandhiselvan and A.K.S. Vijayan.
