In a statement, AIADMK supremo Jayalalithaa said the party is withdrawing its candidate named for Vellore and instead announced K Kittusamy as its nominee from Oddanchathiram.
Jayalalithaa had earlier named former MLA P Neelakandan for the Vellore seat.
MJK has been alloted two seats by the AIADMK.
