Prime Minister of the Daleks

The Prime Minister of the Daleks was the leader of the Parliament of the Daleks of the New Dalek Paradigm.

Biography
After the many defeats that the Eleventh Doctor had inflicted on the New Dalek Paradigm, the Dalek hierarchy was restructured into the Parliament of the Daleks led by the Prime Minister, a genetically boosted Dalek mutant who resided in a cylindrical cabinet of transparent finitoglass. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) The Time Lords understood that the Prime Minister superseded the long-dead Dalek Emperor.

Claiming that this post-Time War establishment was the first Parliament in Dalek history, historians suggested that this Parliament had placed the Master under trial, the Prime Minister itself listing their former ally's crimes. The Prime Minister promoted the Red Daleks to an officer class in the Dalek Imperial Army and had the Dalek drones returned to the style of the Bronze Daleks from the Last Great Time War, a design that the Prime Minister believed would invoke the most fear across the galaxy.

The Prime Minister ordered the abduction of the Eleventh Doctor and his companions, Amy Pond and Rory Williams, summoning them to the Parliament of the Daleks and granting them a mission to lower the indestructible force field of the Dalek Asylum so it could be destroyed to prevent the Daleks in the Asylum from breaking out.

Once this had been achieved by the human-turned-Dalek, Oswin Oswald, the Parliament launched an attack to destroy the Asylum. The Prime Minister's memory of the Doctor had been wiped by Oswin, along with the rest of the Daleks. When the Doctor came back to their ship, he was bombarded with "the Question" ("Doctor Who?") by the Prime Minister and the rest of the Parliament. The Doctor left shortly thereafter.

The sudden deletion of all information concerning the Doctor from the Pathweb caused the Prime Minister of the Daleks to spend whole centuries scrutinising over the mystery of the Daleks' forgotten enemy, going insane in the process.

The Daleks regained their memories of the Doctor’s role as their greatest enemy after Tasha Lem was converted into a Dalek puppet during the Siege of Trenzalore. Upon regaining these memories, the Prime Minister dashed itself against its glass case; the Supreme Dalek declared it unfit for service and exterminated the Prime Minister, becoming the new leader of the Parliament of the Daleks.

Appearance
This particular Dalek mutant did not wear any sort of battle armour casing, but instead situated itself in a cylindrical cabinet of transparent finitoglass, a life-support tank connected to a data feed which was itself linked to an array of high-intensity sensor globes at the top of the structure. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe, Dalek Combat Training Manual) It was surrounded protected by the rest of the Parliament who were armed and would protect him. He was guarded at all times by his second in command, the demoted Dalek Supreme, who assisted him. (TV: Asylum of the Daleks)

Personality
Like the Dalek Time Controller, its voice was softer and more controlled than the staccato ranting usually used by Daleks, as befitted its collected personality; the Prime Minister even demonstrated a snarky streak when taunting the Doctor. (TV: Asylum of the Daleks)

Behind the scenes

 * In a previous draft of Steven Moffat's script for Asylum of the Daleks, the Dalek leader was called simply "the Dalek Prime". Although the final design of the Prime Minister presented a more tubular look, the draft also called for the visible mutant to inhabit a glass sphere (described in similar terms to the big globey thing in The Snowmen), which would have echoed the bulbous casing design of the Dalek Prime from the Daleks comics and John Peel's War of the Daleks. (REF: TCH 70)
 * The Prime Minister of the Daleks marks the first time a Dalek mutant has been seen on-screen since the insane Dalek Caan in the Series 4 finale, The Stolen Earth / Journey's End (although a Dalek Emperor with an exposed mutant was seen in The Adventure Games episode City of the Daleks).
 * The same mould used to create the Dalek Caan mutant was used for the Prime Minister.
 * The Dalek Hierarchy feature of DWFC TLV 1 explains that the Prime Minister led the restored Dalek Empire after a civil war between the New Dalek Paradigm and the "Children of Davros", whom are seen in The Eleventh Doctor Interactive Story. A Dalek Empire favourable to Davros is seen in The Magician's Apprentice and The Witch's Familiar.
