"The manner in which Jawahar Lal Nehru handled the issue of Netaji's disappearance was always suspicious and mischievous," party general secretary Debabrata Biswas said in a statement.
He said that AIFB has always been claiming that Bose's death in the so-called air crash was a conspiracy.
It is unfortunate that the BJP-led NDA government is "also neither serious nor sincere to establish truth about Netaji." The Narendra Modi Government has not done anything in this direction so far.
AIFB, he said, would organise a nation-wide movement and undertake legal and political steps to get all the documents relating to Netaji declassified and establish the truth.
The Intelligence Bureau files declassified recently said Bose's close relatives were spied upon for 20 years between 1948 and 1968. Nehru was Prime Minister for 16 of these 20 years.
