Republic of Great Britain
The Republic of Great Britain was an alternative Great Britain which existed in one parallel universe.
History
The Republic was established at an unknown date prior to 1943 after the execution of the Royal Family for unknown reasons.
It was ruled by a fascist government. (DW: Inferno)
The country developed a close relationship with White Russia and worked with Russia to ensure peace in Europe by crushing Nazi Germany between two vast spheres of influence. The British Republic's ties with Russia lasted well into the 1970s. Kalashnikov and SKS rifles appear to have been the main weapons of the British armed forces.
"The Leader", the President of the Republic, was this world's version of the Doctor. (NA: Timewyrm: Revelation)
The British Republic maintained its own version of UNIT called the Republican Security Forces. The RSF fought a number of alien menaces, including a group of Bannermen who had landed in Wales in 1959, as they had in the Doctor's reality, as well as the Great Intelligence, with the assistance of this reality's version of the Master, still known as Koschei.
