On the issue of declassification of files both the Congress and the BJP are same," Mishra, a CPI(M) Politburo member, said.
"Before coming to power the BJP had promised they will declassify the files. Why aren't they keeping their promise?" Mishra said at a 'Meet the Press' programme at the Press Club.
The Intelligence Bureau files declassified recently said Bose's close relatives, including his two nephews, Sisir Kumar Bose and Amiya Nath Bose, sons of his brother Sarat Chandra Bose, were spied upon for 20 years between 1948 and 1968. Nehru was the prime minister for 16 of these 20 years.
