NEW DELHI: Prime Minister Narendra Modi on Wednesday announced that a grand museum dedicated to all the former prime ministers of the country will be built in Delhi.The PM said this is an effort to honour the legacy of all previous prime ministers, irrespective of their political affiliations, and highlight their contribution to nation building.He made the announcement at at an event to release a book on former Prime Minister Chandra Shekhar, written by Rajya Sabha deputy chairman Harivansh.The PM added that there was an attempt in the past to diminish the legacy of some prime ministers as part of a strategy.Prime Minister Modi said "There is a 'jamat' — a certain section — in the country that made it a habit to tarnish the image of the prime ministers so that their good work would not be remembered. Like for example, they started talking about what a Prime Minister used to drink — in the case of Morarji Desai — instead of the work he did. Or they would say that a prime minister would fall asleep in a meeting.""Even in the case of Lal Bahadur Shashtri, they would have found a way to tarnish his legacy if he would have come alive from Tashkent," he said."But now I have decided that we will create a museum for all prime ministers and start a new political culture," PM Modi said adding, "I request family members of all former PMs to share memorabilia to be kept in this museum so that their legacy lives on."The Prime Minister also spoke about the attempt to defame Chandra Shekhar's famous "Padyatra" from Kanyakumari to Rajghat."There is a fashion today ... Some people have reservations ... even some small leaders hold padayatra of 10-12 kilometres, it gets 24 hours coverage on television and gets published on the front page of newspapers. But Chandra Shekharji did his padayatra keeping in mind the problems of poor and villages. But the country did not give it the honour as it deserved. The opportunity was lost," he said.The PM said Chandra Shekhar's padayatra was maligned by linking it to donation, corruption and capitalists. "Such injustice in public life is annoying," he said.He also said attempts were made to align the image of B R Ambedkar and Sardar Patel after independence.Modi said if today's generation is asked about Morarji Desai and Lal Bahadur Shastri, they hardly know about them.Mentioning names of I K Gujral, Deve Gowda and Manmohan Singh, Modi said everyone of them contributed and this should be acknowledged.(With inputs from agencies)
