The Minister

The Minister was a renegade Time Lord who went by the name Felicity Morgan whilst residing on Samael. At different times through their lives, the Minister adopted different titles including Minister of War.

Biography
After the Celestial Intervention Agency genetically modified her so she would be able to retain her appearance across incarnations, the Minister fled from Gallifrey and entered politics on the planet Samael, where the political system was defined by assassination. Under the name "Felicity Morgan", she began as the Minister of Fisheries and was promoted nine times, being assassinated with each promotion and regenerating into the same face, her personality adjusting each time to fit her new position. Only her two closest assistants knew her secret.

In order, her positions included leadership of the Ministries of Agriculture, Housing, Environment, Health, and Education. Three of her positions involved her in the conflict between Samael's neighboring planets of Raphael and Barachiel: as Minister for War, she aided Raphael against Barachion aggression; as Minister for Industry, she treated both sides as customers for weapons; and as Minister for Foreign Affairs and Diplomacy, she sued for peace, seeking a future of interplanetary cooperation. Through her career, she was able to completely reform Samael's political system.

Finally, she was promoted to Prime Minister. The Third Doctor and Jo Grant attended the transition of power in the Parliament building alongside masked ambassadors from Raphael and Barachiel. After she was assassinated, the group accompanied the Minister and her two assistants to her TARDIS, where she regenerated. While this new incarnation's new personality fitted to the role – grounded, hopeful, firm – it was also vulnerable to psychic attacks.

The Raphaelite ambassador was in fact, who had been manipulating Raphael's politics for years and sought to sabotage her TARDIS and regeneration. He hypnotised Felicity and she regressed to her aggressive "Minister of War" persona, eager to enter Samael into the war on Raphael's behalf. However, Jo helped the Minister remember her values, and she turned against the Master, who disappeared.

The Minister allowed the Doctor to place a psychic block in her mind to protect her sanity and remove her ability to control her regenerations. As she vowed to "do more" good, her male assistant commented that she might begin calling herself the "Minister of Luck". (AUDIO: The Same Face) A version of the Seventh Doctor later encountered a renegade Time Lord named the Minister of Chance. (WC: Death Comes to Time)

Other references
Alice O'Donnell mentioned the Minister of War when listing major events that happened on Earth between 1980 and 2119. She cited the Minister between Harold Saxon's premiership in 2008 and "the moon exploding and a big bat coming out" in 2049. The Twelfth Doctor did not recognise the title but commented that he expected to "find out soon enough". (TV: Before the Flood)

Behind the scenes

 * With the reference to the "Minister of Luck", it is strongly intimated that the first fresh-faced incarnation of the Minister, following on from Prime Minister "Felicity Morgan", would be Stephen Fry's Minister of Chance. The Minister's pledge to "do good" matches the disposition of Fry's Minister at the beginning of Death Comes to Time. However, Death Comes to Time and its direct sequels are not considered valid sources by this Wiki.
 * A "man with a bent nose" similarly intended to be Fry's Minister of Chance was referenced on a few occasions in valid stories, but his title was never used, preventing one from connecting the dots between him and the individual into whom Felicity Morgan regenerated.
