History
During World War II, when it appeared that the United Kingdom would be invaded by Nazi Germany, four citadels were built under the surface of London. They were intended to allow the British government to continue operations if the worst happened. After the war, the citadels were maintained due to the threat posed by the Soviet Union in the Cold War. (AUDIO: The Fifth Citadel)

In the 1950s, the British government created Department C19. (PROSE: The Scales of Injustice)

In the 1970s, the British government sponsored the Inferno Project, led by Professor Stahlman. (TV: Inferno)

Following the downfall of Prime Minister Harriet Jones brought about by the Tenth Doctor on Christmas Day 2006, (TV: The Christmas Invasion) used technology and hypnosis to work his way through the government, eventually being elected Prime Minister in 2008, shortly followed by an invasion of Earth by the Toclafane who the Master was in league with. Earth was ruled by the Master for a year before the destruction of the paradox machine reversed time so that the invasion never happened. (TV: The Sound of Drums/Last of the Time Lords)

In early 2008, when the Cardiff Space-Time Rift fractured resulting in time slips across the world, the government was one of several organisations that noticed the strange appearances that were occurring worldwide and asked if it had anything to do with Torchwood. (TV: End of Days)

In 2050, the British Government was somehow taken over by a Korven called Lomax who turned it into a corrupt, totalitarian government in preparation for the pending Korven invasion. By this time, government agencies MI5 and MI6 appeared to have merged together to form the Department. The British government had also gained control of the Americas, the Pacific Union, and several other countries they considered "lesser". (TV: Regeneration)
