WB IB declassified Netaji files in 2011-12

Files relating to Netaji Subhas Chandra Bose lying with West Bengal Intelligence Bureau were handed over in 2011-12 to National Archives Department, which made them available to public for research in December last year.
The files of the West Bengal Intelligence Bureau, which has been rechristened as Criminal Intelligence Department (CID) now, were declassified by the state government, according to the National Archives.
These files were declassified after the UPA government made public reports of Mukherjee Commission and Khosla Commission, which probed the death of the freedom fighter.
The classified reports were marked to Intelligence Bureau officials in Delhi by the erstwhile West Bengal Intelligence Bureau.

The supporters of Netaji, who have been demanding complete declassification of files pertaining to him, have also been able to get declassified copies of letters between Indian and British Intelligence officials on Bose's death and activities of his relatives.
However, this declassification was done in the UK and the documents are at the National Archives at Kew in Surrey.
