Congress' last ditch efforts to forge an alliance with the DMK was reportedly stonewalled by its senior leader M K Stalin while actor-politician Vijaykanth-led DMDK, wooed by it, has chosen to embrace the BJP combine.

Used to ride piggy-back on either of the two major Dravidian parties, DMK or AIADMK, the Congress is left with no other option but to take the electoral plunge on its own, after a gap of 16 years when it drew a blank.
While AIADMK is contesting on its own all 40 seats, including one in neighbouring Union Territory of Puducherry, DMK has firmed up an alliance with IUML, MMK, VCK and Puthiya Tamizhagam.
