TMC supremo, Mamata Banerjee’s efforts to pull her own minister,Dinesh Trivedi, down from the post of Railway Minister has failed, so far as the PM clarified , he would want Trivedi to continue till the Budget Session. Now even the pressure from within the party seemed to be failing. Trivedi wants TMC supremo to give in writing that she wants him to quit! Some voices inside the TMC are also rising against the supremo’s stubborn behaviour towards Trivedi.
