A NATIONAL appeal for codebreakers to volunteer for one last act of service for their country has been heeded by the last survivor of the of Bletchley Park team who cracked Hitler's most secret cypher.

Senior Second World War Government codebreaker Captain Jerry Roberts, 92, has risen to the challenge of trying to crack a cypher, discovered on the carcass of a carrier pigeon recently found inside a chimney.

The secret D-Day message has stumped Britain's finest minds.

Mr Roberts is the only surviving member of the nine Second World War cryptanalysts based at Bletchley Park, who successfully decoded Tunny, the most secure warrtime code used by the Germans.

This week he said that he had already responded to the appeal and attempted to decypher the "pigeon service" code that has so far defeated the experts at intelligence agency GCHQ.
