Suvendu Adhikari, West Bengal Chief Minister Mamata Banerjee's one-time right-hand man who crossed over to the BJP in December, will take on the Trinamool Congress in a do-or-die contest in the state elections that begin later this month, his party announced on Saturday. Releasing the first list of candidates for the Bengal polls with 57 contenders, the BJP pitted its most important acquisition against the two-time Chief Minister as part of its all-out campaign to wrest one of the few states where it has historically had little traction until recently.
