Behind the scenes
- Though not given the full title "People's Republic of Great Britain" in dialogue, in Doomsday, Jake Simmonds — while inside the parallel London's Torchwood Tower — says, "Parallel Earth, parallel Torchwood, except we found out what the institute was doing and the People's Republic took control."
- The People's Republic of Great Britain is not to be confused with the Republic of Great Britain, which existed on Inferno Earth.
