"NDA (in Tamil Nadu) would shape up soon, some time around the Pongal festival (January 15)," BJP National Secretary H Raja told reporters here.
He said the election work for the 2014 Lok Sabha polls was delayed as cobbling of alliance with several parties had taken considerable time.
"That is why we had to face losses (electoral) in some constituencies in the 2014 Lok Sabha polls", he said.
BJP had parties including the DMDK, MDMK, and PMK in the NDA for the Lok Sabha polls in Tamil Nadu in 2014.
Subsequently, MDMK snapped ties with the BJP in December 2014 and PMK said its relation with the Saffron party was confined to the Centre.
PMK, however, continues to maintain that all parties including the BJP were welcome to join its front for the Assembly polls provided they accepted the candidature of its leader Anbumani Ramadoss for the post of the Chief Minister.
