The Houses of Parliament were the two houses of England's, later the United Kingdom's, legislature: the House of Commons and the House of Lords. (GAME: The Gunpowder Plot) These were built in a way that made them appear balanced across two axes, land to river, and from the Commons' Speaker's Chair to the Lords' Woolsack. (PROSE: The Book of the War) Parliament ratified laws and gave assent to British monarch if they wished to raise taxes. (GAME: The Gunpowder Plot) When Faction Paradox made the Gregorian Compact with George II, the Houses of Parliament became the center of their Eleven-Day Empire. (PROSE: Interference)
In November 1605, Robert Catesby and Guy Fawkes plotted to blow up Parliament as he opposed King James I's anti-Catholic regime. Lady Winters, a Rutan from the crashed ship, awoke from suspended animation and attempted to use the Gunpowder Plot to her advantage by propelling her ship with the explosion. The Eleventh Doctor safely placed Parliament in Earth orbit, while he used a handful of gunpowder barrels belonging to the plotter Guy Fawkes to allow the ship still be launched. Having traced Winters' distress call, Sontarans and Rutans fought with one another inside Parliament while searching for these weapons, but were forced into ceasefire when the Doctor reprogrammed one of weapons to target the Rutans, risking one of the two species to kill their own kind. The Doctor returned Parliament to its rightful place and Fawkes was caught by the king's men before he could light the remaining 36 gunpowder barrels. (GAME: The Gunpowder Plot)
The days 2-14 September 1752 were "lost" with the conversion from the Julian calendar to the Gregorian calendar. The London existence of that period was purchased from George II by Grandfather Paradox on behalf of Faction Paradox in the Gregorian Compact, and became their heartland known as the Eleven-Day Empire. The Empire was governed from the chamber of the House of Commons; the speaker's chair was empty, waiting for Grandfather Paradox's return. (PROSE: Interference - Book One)
In 1941, during the London Blitz, the Daleks sent an electrical wave that turned on all electronic devices, making the Houses of Parliament and the rest of London light up. (TV: Victory of the Daleks)
In the early morning of 1 January 2005, the newly regenerated Eleventh Doctor flew west over the Houses of Parliament whilst clinging by his fingers from his TARDIS' doorway. He narrowly escaped ramming the clock tower, before climbing back aboard and being thrown nearly nine years back in time. (TV: The Eleventh Hour)
In 2009, in an alternate timeline created by Sarah Jane's actions in 1951 in which the world was destroyed, Luke, Sarah and the Trickster stood at the remains of the Houses of Parliament. (TV: The Temptation of Sarah Jane Smith)
Parliament was an early target of the Daleks in the 2157 invasion; the politicians were rounded up and exterminated in Parliament Square. (PROSE: Alien Bodies) Westminster still standing circa 2167, with Daleks patrolling the adjacent Westminster Bridge. (TV: The Dalek Invasion of Earth) For decades after the liberation of Earth, parliament didn't exist and Britain was split into "domains"; in 2199, the Houses were still being restored. (PROSE: Legacy of the Daleks)
Eleven-Day Empire Edit
Though the Eleven-Day Empire was purchased in 1752, its Parliament buildings were based on the ones built at Westminster after the old Parliament burned down during the Star Chamber's attack on the Empire on 16 October, 1834. Godfather Morlock said this was because the newer Parliament buildings "cast longer shadows".
630 Fathers and Mothers of the Faction sat in the House of Commons. They were presided over by the Acting Speaker, since the actual Speaker's Chair was traditionally left empty for Grandfather Paradox. However, not even the highest-ranking members of the Faction would cross the threshold into the House of Lords, and no one would say what lay within. The only person to have entered and left was Cousin Anastasia, who emerged after an hour covered in blood and missing one finger, declaring the formation of the Thirteen-Day Republic.
In 2005, after finding he had a listening device planted on him, the Eighth Doctor joked, "If we're going to blow up Parliament, we'll need some first-rate gunpowder and some trustworthy Catholic horses." (COMIC: The Flood)
