Dalek Emperor (The Novel of the Film)

A Dalek Emperor, (PROSE: The Novel of the Film) also holding the title of Dalek Supreme, (PROSE: The TV Movie) presided over the Master's trial on Skaro. Citing his crimes against the Daleks and his deliberate attempts to destroy them and usurp their "rightful place as the supreme creatures of the universe", the Emperor sentenced the Master to extermination. The Emperor then listed the Master's crimes against the Daleks, citing various times they had joined forces, only for the Master to betray them at the last moment when it looked as if he was in danger of sacrificing his own being for their cause. Finally, the Master was exterminated by the Dalek Prelature, after which his remains were taken by Seventh Doctor. (PROSE: The Novel of the Film)

Behind the scenes
In the original novelisation of the Doctor Who TV Movie, the Dalek in charge of the Master's trial was clearly identified as the Dalek Emperor. However, in the revised Target edition, all mentions of a "Dalek Emperor" were replaced by the term "Dalek Supreme". Asked on Twitter about the change, Gary Russell confessed that he did not "recall consciously doing that", adding that this lack of recollection may meant hat "it may have been a BBC Books decision".
