Observing that its first priority was to unseat the 'undemocratic' All India Anna Dravida Munnetra Kazhagam government from power, the Congress on Saturday said it will think of a coalition government in Tamil Nadu only after the Assembly polls.

"Our first priority now is to unseat the undemocratic and autocratic AIADMK government. We will think of a coalition government only after the polls," Congress Working Committee member and party observer for Tamil Nadu, Veerappa Moily, said before meeting Dravida Munnetra Kazhagam chief M Karunanidhi to discuss seat sharing arrangements.

Moily said Tamil Nadu has a legacy of single party governments and that he was not sure whether it can be broken now.

The Congress expected that a 'respectable number of seats' will be allotted to it in the DMK-led Democratic Progressive Alliance.

All the parties in the DPA should adopt a 'give and take' approach while sharing the seats.

Accusing the AIADMK of betraying its 2001 allies including the Congress, he said the ruling party in the state had been isolated politically, with no takers for its invitation for an alliance.

The 'tension' in DPA had gone with Marumalarchi Dravida Munnetra Kazhagam chief Vaiko saying that his party will continue in the alliance, he said.

The Congress leader said he will discuss the issue of seat-sharing with Karunanidhi tonight.

"It will be a preliminary discussion," he said.
