Telangana Chief Minister K Chandrasekhar Rao met DMK president M Karunanidhi at his residence in Chennai on Sunday.

The TRS leader, who was welcomed by Stalin at the Gopalapuram residence of Karunanidhi, later left for the house of the Leader of Opposition in the Tamil Nadu Assembly, who also joined him in the same vehicle.

Earlier, the Telangana chief minister had met West Bengal Chief Minister and Trinamool Congress chief Mamata Banerjee as part of efforts to build a non-Congress, non-BJP third front ahead of the 2019 Lok Sabha polls.

Rao stayed at Karunanidhi's residence for a brief period before proceeding to Stalin's house, where the latter hosted lunch for him. Rao stayed at Karunanidhi’s residence for a brief period before proceeding to Stalin’s house, where the latter hosted lunch for him.

Stalin had said his party “endorsed” the efforts of Mamata Banerjee to bring together various parties against the BJP.

The DMK and Congress are allies in Tamil Nadu and the two had faced the 2016 Assembly elections as part of an alliance.

"This is not the beginning and not the end. We have been discussing and it will take 2-3 months to reach a consensus,” Rao said.

Rao hailed DMK supreme M.K Karunnithi as the voice of state rights in South India.

Stalin said the discussion was focused on strengthening states. “I invited KCR to participate in the State Autonomy Conference being planned by the DMK soon. Political decisions including alliances can be decided only by the internal decision making bodies, including general and executive councils,” he said.
