Trinamool Congress's Abhishek Banerjee, who is also West Bengal Chief Minister Mamata Banerjee's nephew, has emerged as the BJP's favourite target as the young politician is groomed as the future leader of the party. Mamata Banerjee will remain in charge, say Trinamool leaders as they admit in the same breath that Abhishek Banerjee's stature and role in the party has grown in the last few years. The 33-year-old - a second-term MP from South 24 Parganas District's Diamond Harbour - has been the BJP's punching bag amid a high-pitched election campaign.
