AIADMK Deputy General Secretary T T V Dinakaran, also the party's candidate in the hustings scheduled next month, had earlier in the day welcomed the support of opposition parties, including DMK and Congress to defeat DMK.
TNCC President S Thirunavukkarasar ruled out any such possibility and recalled his party's support to the DMK in the bypoll.
"Chances of Congress supporting a party politically are very very miniscule. There is no possibility. Also, we have already made our stand (of supporting DMK) clear," he told reporters here.
Dinakaran had earlier in the day insisted that DMK was AIADMK's main rival and welcomed the support of other parties.
"DMK is our rival and that is the policy of (party founder the late) MG Ramachandran and Amma. I am contesting from RK Nagar to prevent a DMK win and therefore will accept the support of others, whether it be MDMK, DMDK, BJP or even Congress," he had said.
