Tony Sale, the brilliant engineer who led the rebuild of Colossus, the first modern computer, has died aged 80.

The mammoth project to recreate the code-cracking Colossus capped a career built around electronics and computers.

Most recently, Mr Sale drove the campaign to save Bletchley Park, where Colossus aided Allied code-cracking efforts during World War II.
