Bletchley Park, the spy centre celebrated in the film Enigma, should be reassembled to combat international terrorism, the Chancellor Gordon Brown will say in a speech on Monday.
The original Bletchley Park operation brought together some of the finest minds in Britain to break the Enigma code used in German military and intelligence communications.
Using the world's first programmable electronic computer, they saved thousands of tons of shipping, made the D-Day landings possible, and are said to have shortened the war by two years.
Speaking to members of the Royal United Services Institute in Whitehall, Mr Brown will say: "I have found myself immersed in measures designed to cut off the sources of terrorist finance.
"This requires an international operation using modern methods of forensic accounting as imaginative and pathbreaking for our times as the Enigma codebreakers."
