The Bengal election results have proved that the BJP can be defeated and people have shown the way, Mamata Banerjee said today on her remarkable victory. “They need political oxygen now,” she told NDTV in an exclusive interview. “The BJP can be defeated. It is the people’s choice. People have shown the way. In a democracy you should not show audacity or ego,” she said. On the post-poll violence in parts of the state, Mamata Banerjee also accused the BJP of trying to create trouble in areas where they have won.
