Behind the scenes

 * According to The Writer's Tale, originally in The Stolen Earth or Journey's End, Prime Minister Fairchild was to have been exterminated by the Daleks at Westminster.
 * According to non-narrative material in DWBIT 1, Westminster was one of the forefronts of the Dalek's invasion in the 22nd century. A Dalek Saucer attacked London. The British government put all their best defences into battle against them, sending the Air Force's helicopters and fighters to attack the Dalek ship. Tanks fought across the streets, and the Navy fought with gunboats. The humans were persistent, destroying many Daleks, but in a matter of days the Daleks subjugated the humans.
