While the BJP wants to field its state president Pon Radhakrishnan from Kanyakumari parliamentary seat, it wants certain other seats including South Chennai (senior leader L Ganesan, a strong contender) and Coimbatore (several aspirants for this seat).
Likewise, MDMK wants to field its chief Vaiko from Virudhunagar and has decided to renominate its sitting Lok Sabha MP A Ganesamoorthy from Erode.
Although Theni, Madurai and Thanjavur are among the MDMK's "wishlist of seats," the party has indicated that it was open for negotiation.
A senior BJP leader requesting anonymity said "it was a challenging situation" as the interests of all the parties had to be protected.
Meanwhile, senior BJP leader L Ganesan speaking to reporters here said "issues could crop up in seat sharing. We are however determined to amicably settle this and declare the seat allocation on March 14.
