Republic of Great Britain

The Republic of Great Britain was an alternate Great Britain that existed in a parallel universe. It was established sometime before 1943 and governed by a totalitarian regime. (DW: Inferno)

The Republic of Great Britain maintained it's own version of UNIT, the Republican Security Forces, who fought a number of alien menaces, including a group of Bannermen who landed in Wales in 1959 and the Great Intelligence (with the assistance of the Master, still known as Koschei in this universe).

The Leader of the Republic was this world's version of the Doctor who used his superior intellect to take over the United Kingdom after his exile by the Time Lords (NA: Timewyrm: Revelation)
