NDTV

The spokespersons of four major parties had a fierce debate today on what could be the X factor in the Tamil Nadu assembly election. At the NDTV Tamil Nadu Summit, convenor of the state BJP's coordination committee, H Raja, fired the first shot.

Suraaj Party founder Prashant Kishor on Friday claimed that migrants from Bihar, who returned home for Chhath festivities and have not yet gone back to their places of work, are the X factor in the assembly polls.
