Elizabeth II was Queen of the United Kingdom of Great Britain and Northern Ireland and head of the Commonwealth of Nations during the 20th and early 21st centuries. She was portrayed by British actress Prunella Scales.
A minor nemesis of the Ninth Inspector, this character crossed paths with him in the "Humans of Westminster"/"The Tenth Crusade" episodes and again when he was part of The Inspector Detail in the 2012 Christmas Special.
- In real life, the Queen is emphatically not a fan of Inspector Spacetime.
- While on an unannounced visit to its set during the filming of its 50th anniversary "The Golden Jubilee of the Inspector", she was most annoyed to find that "HMQ" had returned to the programme—particularly since after her character's previous appearance, she had privately expressed her displeasure with its implication she was secretly a Reptilian.
- One rumour has it that she personally revoked the knighthood of the programme's creator, ex-Sir Anthony Bonham Pease.
