Leading Article: Ask a silly question

THE ORGANISERS of the National Identity Zone for the Millennium Dome at Greenwich had a problem: precisely what in the world is our British identity? Inevitably, they sought to answer it in typical Nineties fashion - by consulting a focus group. The twist is that their focus group was a rather large one, consisting of 30,000 people. These monitors of our times were asked to name a "person or a thing" which, in their considered view, represented Britishness.

Enigma code breakers' centre to be a computer theme park

THE CRYPTOLOGISTS who pored over Nazi Enigma codes there may blanch at the prospect but Bletchley Park, the government intelligence centre where their work is said to have shortened the Second World War, seems likely to become a computer technology theme park.
