Bradley Manning (now Chelsea), as most people know, is a 24-year-old US soldier accused (now convicted) of releasing 250,000 secret cables and logs about the Iraq and Afghan wars to WikiLeaks. What is less well know is that he spent over two of his early teenage years at school in Haverfordwest after his Welsh mum split up with his American dad. Tim Price has seized on this to create a fact-inspired fictional play, looking at the forces that radicalized Manning. Price's piece raises acute moral and ethical questions.
