TMC MP Kalyan Banerjee criticised Mamata Banerjee's nephew Abhishek Banerjee, alleging that Abhishek dropped him as his lawyer at the last moment in the ongoing signature forgery case. "I stand with Mamata didi, but she must make a choice now (between me and Abhishek). I was informed around midnight that the lawyer had been changed. It was humiliating," he said.
