CPI(M)- BJP alliance?

During the recently concluded CPI(M) congress ,Polit Bureau member S Ramachandran Pillai put forth a weird line of reasoning for opposing the Congress tooth and nail at the centre while allying with it in Tamil Nadu.

To a question on aligning with DMK-led Front in Tamil Nadu, in which the Congress is also an ally, Pillai said the CPI(M) has relationship only with the DMK and has no truck with Congress in the state

Lovely logic. Is the CPI(M) ready to join a AIADMK-BJP alliance? It can have its "relationship" with the AIADMK and still have "no truck" with the BJP.
