New Delhi, April 26 (IANS): Two specific files, including one from the Prime Minister's Office (PMO), related to Netaji Subhas Chandra Bose are missing, Minister of State for Home Kiren Rijiju said in the Lok Sabha on Tuesday.

He also informed the house that Japan has agreed to declassify two files related to Netaji by end of the year.

"Despite attempts being made, one file is missing from the ministry of home affairs also," Rijiju said during question hour.

The file that's missing from the PMO relates to the "proposal" to bring back the ashes of Netaji from Tokyo and on building a national memorial in his honour at the Red Fort, he said.

Replying to supplementary questions from members, including Bhrutihari Mahtab of Biju Janata Dal, the minister said efforts have been made by the Narendra Modi government to procure records, files and documents from various countries, including Russia and Japan.

"Japan has agreed to declassify two files out of five by the end of this year," he said.

Rijiju said that Japan has not given any assurance about the other three files.

He said the government has decided to declassify 25 files every month.
