The West Bengal government had recently released 64 secret Netaji files.
Thirty-five members of Netaji Subhas Chandra Bose's family from across the world are meeting Prime Minister Narendra Modi at his 7 Race Course Road residence today.
The family is expected to seek declassification of all the files related to Netaji, whose disappearance 70 years ago remains a mystery.
"The Prime Minister had told my cousins that he would 'do it together with the Bose family' and now he has called the entire Bose family," Netaji's grand-niece Jayanti Rakshit told NDTV. "We are expecting to open the files that have been kept hidden with the Central government for a long time. Unless the Prime Minister takes an initiative, it won't happen."
The Prime Minister had announced the visit in his monthly radio address 'Mann Ki Baat' on September 20. In a tweet last night, he described it as a special day and an "honour".
But he had not made any mention of declassifying the files.
"Successive governments have suppressed all documents related to the great leader and it is the call of the nation that the documents be revealed. I'm sure the Prime Minister will respond positively," said Netaji's grand-nephew Chandra Kumar Bose.
The family, he said, will also appeal to PM Modi to write to countries including Russia, Japan, China, America, UK, Japan, Singapore and Malaysia to declassify all Netaji files. The leader was in touch with authorities and people in these countries. "If we do not declassify files in India, how can we ask other nations to do it?" he added.
On September 18, the West Bengal government had declassified 64 files related to Netaji. Chief Minister Mamata Banerjee had said the Centre should follow the lead of the state government.
Netaji's daughter, 72-year-old Anita Bose Pfaff, who had also urged the PM to declassify the files, however, is not expected to be at today's gathering. "I certainly would like the 'mystery' settled," Ms Pfaff had been quoted as saying by news agency Press Trust of India.
But the noted economist had reportedly added, "I wish the Indian public would concern themselves more with his life and his achievements from which there is much to be learnt, than with his death."
