Let's say that somehow, by some miracle, the Axis has forced Britain into an unconditional surrender. I imagine that, when it came time to divvy up the country, her dominions, and the British Empire, Germany would preside over the Isles themselves while, at the very least, Italy would get most of Africa and Japan, most of Asia. But were formal plans for this ever devised? I'm especially curious as to their plans for the Isles.
