Senior leaders of BJP's Tamil Nadu unit left here for Delhi this afternoon to meet party President Rajnath Singh to get his stamp of approval for the deal, party sources said.
"You will know everything by this evening...We are meeting Rajnath Singh... We want to complete this exercise today itself," BJP national Executive member L Ganesan, a former state unit chief, told PTI.
State union President Pon Radhakrishnan and Ganesan among others are expected to meet Singh this evening.
"The problem is with regard to only very few seats and this is being resolved," a BJP leader said declining to be named.
BJP has so far roped in the Vaiko-led MDMK and some fledgling parties, including IJK. MDMK is demanding that it be treated on a par with the PMK and the DMDK in seat allocation.
