MI5 documents

Children

According to MI5 documents that remained classified until 2014, the British believed Nambiar was a Soviet spy before the war. The documents show that a Soviet defector in the 1950s said Nambiar had been an agent of the GRU in the 1920s. Nambiar had visited Moscow in 1929 while active in Indian communist organisations. (The declassified documents also included correspondence between Nambiar and Bose captured after the surrender of German submarine U-234.)[5]
