OPINION: Why can't Mamata sideline Abhishek?

Mamata Banerjee must be spending sleepless nights these days because of rebellion in her party. Her one-time confidante Kalyan Banerjee gave her an ultimatum to choose between him or her nephew Abhishek. In other words, Kalyan Banerjee threatened to quit. Another veteran Trinamool MP, Saugata Roy, said it has now become difficult for him to either meet or speak to Mamata nowadays. In Bengal, commoners continue to throw eggs at local TMC leaders, crores of rupees were seized from a TMC leader's school, and Falta strongman Jahangir Khan was paraded by police in his hometown.  Images that are coming from Bengal are sure to shock Mamata Banerjee.
