Amanda Hill, the chief brands officer at the corporation's commercial arm BBC Worldwide, said: "Doctor Who encompasses British creativity at its best and we're passionate about it being on the world stage.

"This tour is something normally reserved for Hollywood blockbusters but with Doctor Who it appears you can do anything you dream of and continue to challenge what's perceived as the norm in TV."
