NEW DELHI: CV Ananda Bose, who stepped down as West Bengal governor after a sudden resignation, said on Sunday the move was a “conscious decision,” even though he remained tight lipped about the reasons for his exit.Bose said the reason behind his resignation will “remain confidential till the right time comes”.Speaking to reporters at the Kolkata airport, Bose told news agency PTI that he, however, would return to Bengal to cast his vote.Bose, a native of Kerala, had shifted his voting base to Bengal barely a week before tendering resignation from his office.“I took a conscious decision to put in my papers, the reasons of which will remain confidential till the right time arrives,” Bose said.“The rules of this game include knowing when it ends,” he added.Bose avoided a direct response when asked to comment on the angst expressed by President Droupadi Murmu on alleged protocol violations and tribal deprivation in the state.“The President is very experienced, balanced and an extremely dignified person. She must have had her reasons for saying what she said. But I am no one to comment on what the President said,” the ex-Bengal governor said.President Droupadi Murmu on Saturday expressed strong displeasure after TMC-ruled West Bengal government changed the venue of an event she was supposed to attend. Later, the row over last-minute venue change in President Murmu’s Santhal event escalated, with Prime Minister Narendra Modi slamming the TMC government in the state and claiming that they were against tribal communities.Bengal chief minister Mamata Banerjee hit back at the BJP for “using” the President to “malign” the state, advising Murmu to “not indulge in politics”. Earlier, Murmu had flagged concerns over venue change accusing the state administration of choosing a place where “Santhal people can’t go”.
