Minister of Chance

The Minister of Chance was a renegade Time Lord.

Biography
The Minister thwarted General Tannis' plans to infect the planet Alnelan with a deadly plague, but his female assistant "wandered off" on the planet.

Following his defeat Tannis agreed to the Treaty of Karselai and signed away any rights to alien planets. Despite this, the Canisian military, led by Tannis, brutally conquered the Santine Republic, confining the leading members of the Republic to a prison camp. The Minister, who was able to transfer a virus to a Canisian computer via speech, seeded a rebellion on Santiny while the Seventh Doctor investigated the deaths of two Time Lords on Earth. Tannis was also working towards wiping out the last members of the Fraction, and by massacring the Santine prisoners he provoked the Minister into breaking the rules about non-interference and destroy the fleet.

Due to the Minister's violation of the rules, the Doctor was forced to confront him and revoke his TARDIS. (WC: Death Comes to Time) The Minister instead learned to travel between worlds using the formula for doors. In a new incarnation, he met Kitty in Tantillion and travelled with her as he fought Rathen. (PROSE: The Minister of Chance)

Beyond Death Comes to Time
In Dan Freedman's pitch for a continuation of the Death Comes to Time storyline, the Minister of Chance would have taken up the Doctor's mantle out of guilt. Though this series was not commissioned by the BBC, Freedman later crowdfunded it as the Minister of Chance audio series, where the character had regenerated into an incarnation played by Julian Wadham; Sylvester McCoy and Paul McGann also appeared in the series, though not as their Doctor Who characters. The audio series was later novelised by Freedman for Arcbeatle Press.

Appearances in valid sources
In addition to the material detailed above that continued directly from the atypical Doctor Who universe depicted in Death Comes to Time, the character has also been referenced in media considered valid by our Wiki on multiple occasions.

In the novel The Tomorrow Windows, the Eighth Doctor saw a man with a bent nose in one of the Tomorrow Windows. This character later appeared holding a pair of dice in in the novel The Gallifrey Chronicles as one of the four surviving elementals; in Lance Parkin's AHistory, he confirmed that this was a reference to the Minister of Chance. Both The Tomorrow Windows and The Gallifrey Chronicles featured other references to Death Comes to Time by mentioning Anima Persis and Tannis, respectively. The man with the broken nose and the dice, depicted with Fry's likeness (albeit in shadow), also made a visual cameo in Miranda.

The Big Finish audio story The Same Face featured a renegade Time Lord going by the name of "the Minister". The story explained that her ten first incarnations looked identical due to a mental block affecting her regeneration ability; the only difference was their personality, which adapted to fit the political roles which she used as her name, from Minister for Fisheries to Minister of War. As the Doctor released her mental block, one of her assistants quipped that she should start calling herself "the Minister of Luck". She then pledged to continue trying to do good, matching Stephen Fry's Minister's idealistic interventionism in Death Comes to Time.
