Netaji Research Bureau chairperson Sugata Bose has shot off a letter to the Victoria Memorial authorities, claiming that one of the relics at an ongoing exhibition at the museum, commemorating the 125th birth anniversary of the legendary freedom fighter, is fake. In the letter to Victoria Memorial Curator Jayanta Sengupta, the leader s grandnephew said the museum authorities had never asked for a copy of Netaji s resignation letter from the Indian Civil Service and what has been put on display there is a fake exhibit. The Harvard University professor and son of Dr Sisir Bose said the authentic photocopy of Netaji s resignation letter from the ICS has been with the bureau for about 50 years.
