A Western businessman who has had the rare chance to travel throughout North Korea has sent these images of daily life to the BBC News website. These are his observations from within the normally secretive state.
I could travel more or less where I pleased for my work, and even though we always had translators and minders, I was rarely prevented from taking photographs.
I am under no illusions about the nature of the state. What I saw was how North Koreans live and work.
