Parliament of the Daleks
The Parliament of the Daleks was a large spaceship used by the Daleks as their parliament. The Parliament consisted of an immense number of Daleks headed by their Prime Minister. A Supreme Dalek served as second-in-command, then there was a Strategist Dalek, several Drone Daleks, and hundreds of drones of a design resembling those from the Last Great Time War.

History
The Prime Minister ordered the abduction of the Eleventh Doctor and his companions Amy Pond and Rory Williams bringing them to the Parliament of the Daleks and giving them a mission to lower the indestructible force field of the Dalek Asylum.
Once this had been achieved by the human-turned Dalek, Oswin Oswald, the Parliament launched an attack to destroy the Asylum. Oswin had erased the Doctor from the memory of all members of the Parliament, leaving them confused when the Doctor returned. They all repeatedly asked "the First Question" ("Doctor Who?") before he soon left. (DW: Asylum of the Daleks)
