Alternative timeline
In an alternative timeline, Thatcher was assassinated by her fellow Conservative politician Heathcliffe Bower in 1984. However, the proper timeline was restored by the Fifth Doctor. (PROSE: The Assassin's Story)

Continuity
The reference to a female prime minister in Terror of the Zygons was an ad-lib by Nicholas Courtney, according to the DVD commentary for Frontier in Space. It could suggest that in the Doctor Who universe either Thatcher was elected PM earlier than in real life or that, as intended by the production team, the UNIT stories took place in the near future. The BBC's Doctor Who Classic Series website, however, claims that the Prime minister was, with Labour taking over from a collapsing Jeremy Thorpe government. In real life, Thatcher resigned as prime minister in 1990, but this has yet to be confirmed in the continuity of the franchise.

Satirical portrayals
Margaret Thatcher inspired some unflattering portrayals in the Whoniverse. The misguided dictator Helen A from The Happiness Patrol is widely supposed to be based upon her, whereas the villainess Rehctaht, the female villain of Turlough and the Earthlink Dilemma, has the name Thatcher, spelled backwards.

A villainess named "Thatchos" (a Cyber-Leader in a fright wig) appeared in a Doctor Who parody on The Lenny Henry Show.
