DMK President M Karunanidhi said talks were on with DMDK and he had not lost his confidence that it would join hands with his party.
"Happening," he told reporters here when asked if talks were on with the DMDK.
"I have not lost my confidence (that DMDK would join the DMK-led front)," said Karunanidhi, whose party was among those which have persistently wooed Vijayakanth for an alliance.
Besides the DMK, BJP and four party bloc People's Welfare Front continue to woo the DMDK.

Replying to another question Karunanidhi, however, said he would not be able to give a definitive answer on the timing of the announcement over the tie-up with DMDK and quipped "it may come."
On the number of seats DMK would contest, he said, "it would neither be appropriate for me to spell that out nor civil for you to pose that question at this juncture."
