The election manifesto of the Dravida Munettra Kazhagam (DMK) pledged to push the central government for a referendum, held amongst the Tamil of the North-East of Sri Lanka, and migrant Tamils living abroad, to decide on a permanent political solution.
The manifesto also said the party would press for the full implementation of the 13th Amendment on the island and that it would appoint Tamil speaking envoys to countries with large diaspora populations.
Party stalwart M Karunanidhi said the DMK would not support any candidate to become Prime Minister.
"The party supports neither Rahul Gandhi and Narendra Modi as PM candidates," he said, adding that it would not be a setback to the DMK to contest without being in an alliance with a national party.
