"AIFB welcomes decision of state government. We hope these papers will throw more light on the plan and procedure of Netaji by utilising the situation of World War II in favour of liberation of our motherland, India.
"It will also reveal conspiracy of the then Congress party to keep Netaji away from Independent India," AIFB general secretary Debabrata Biswas said in a statement.
The All India Forward Bloc was formed by Netaji Subhas Chandra Bose himself.
In the era of World Trade Organisation, all countries are keeping relation with each other on the basis of commerce, he argued.
"Moreover, history and geography of many countries have changed since 1945, the end of World War II," Biswas added.
He appealed the Mamata Banerjee government to keep the declassified files in such a place that general public and researchers can access them easily.
