First Brit with bionic leg brace

A man from London has become the first Briton to walk with the help of a bionic leg brace.

John Simpson wasn't able to walk without help before being fitted with the C-brace.

It uses a built-in computer and sensors to allow the knee to control walking.

John says: "It's going to change my life."
