Expelled TMC spokesperson Riju Dutta on Sunday criticised former West Bengal CM Mamata Banerjee after TMC leader Chandrima Bhattacharya resigned from all party posts. "Didi's entire team is busy labelling everyone else as traitors and dishonest," Dutta said. "The fact is that someone or other is leaving her everyday...Why is everyone leaving? That is the question that arises," he added.
