Chennai: The DMK-Congress seat-sharing talks for Tamil Nadu Assembly polls failed to make any headway as AICC president Sonia Gandhi's special emissary Ghulam Nabi Azad and DMK Chief M Karunanidhi played hard to get.

Azad clearly indicated that the DMK’s demand for increased number of seats and a share in power had led to the present situation will not be granted.

Azad, in charge of Congress affairs in Tamil Nadu, was in Chennai to take the second round of discussions further between the two parties.

After meeting Karunanidhi, Azad said, "Whatever has come out of the discussion, I have to discuss with my leadership. We will have another round of meeting soon", he said.

The talks have, however, not been able to break the deadlock with parties haggling hard over the number of seats and power sharing.

The Assembly elections are scheduled for April 13. With barely 16 days left for filing of nominations, the two key UPA allies are under increasing pressure to reach a seat sharing deal.
