Veteran Trinamool Congress (TMC) MP Sisir Adhikari — father of BJP heavyweight Suvendu Adhikari — joined the BJP here on Sunday in the presence of Union Home Minister Amit Shah and other senior leaders of the party.

The patriarch of the Adhikari family – which wields considerable influence in Bengal’s Purba Medinipur district – said that he had to work really hard to rise through the ranks in the TMC, but the treatment meted out to him and his sons, of late, forced him to switch camp.
