MEERUT: A day after the SC appointed an amicus curiae to consider a fresh probe into Mahatma Gandhi's assassination, Hindu Mahasabha lashed out at BJP and RSS for "going all-out to destroy Mahasabha's legacy of assassinating Gandhi by unnecessarily raising the 4th bullet theory".On Friday , the apex court had appointed former additional solicitor general Amarendra Sharan as amicus curiae to look into documents pertaining to Mahatma Gandhi's assassination after Mumbai-based petitioner Pankaj Phadnis claimed that Gandhi was killed by a fourth bullet fired by an unidentified person who never came into light.Hindu Mahasabha national VP Ashok Sharma said, "Both BJP and RSS owe their existence to the ideology conceived by Hindu Mahasabha and they know that it is only this outfit which can expose the mask these two organisations wear today.Besides, since Mahasabha's identity is inseparable from Nathuram Godse 's, they are trying to create some doubt over his role in the assassination to deny him the credit. They know that Mahasabha will be marginalised without Godse."
