I have to write an essay about secrecy of correspondence in Britain. I always thought that this is a law in Britain but I can't find anything about it. I've had a glance through the data protection act but I couldn't find anything about secrecy of correspondence. I'm now wondering whether it's just a principle rather than a law? Does anyone know more about this? Or does anyone know where to find out more about it (links) ?
...or just paranoid?
