The political temperature in West Bengal is rising ahead of Phase 2 of the Assembly elections. Chief Minister Mamata Banerjee has announced legal action against Union Home Minister Amit Shah over his controversial ‘hang them upside down’ remark, while Congress leader Rahul Gandhi has targeted Mamata, questioning the lack of ED and CBI probes against her. At the same time, both Mamata and Shah are making big claims over Phase 1 results, turning the Bengal poll battle into a high-stakes prestige fight.
