Sorry, but this flag is uncorrect. According the bylaws or constitution of the party the flag is in pakistanese pattern but reversed colors (vertical 1/3 green + 2/3 white), and with a red star (instead half moon and star) in the white part. This flag appear in Flag Report issue 80. Notice that this party was the political wing of the National Liberation Front of Twipra and the flag was directly derived from the flag of this organization. Green mean sovereignity, white mean peace, and red mean revolution; the star is the guide of the borok nation. Jaume Ollé - Catalonia.
