Challenge accepted, West Bengal Chief Minister Mamata Banerjee roared on Friday, saying she was not scared of the BJP's threat to "put Trinamool Congress in jail" and vowed to "capture Delhi." She was responding to BJP chief Amit Shah's targeted attack on her and her party during a two-day visit to the state aimed at rapidly expanding his party's footprint in West Bengal, where it has so far had limited political presence. Mr Shah has handed his Bengal BJP team the task of uprooting the ruling Trinamool Congress by 2019.
