Dalek leader (Revolution of the Daleks)

A Dalek identified itself as leader of the Death Squad Daleks aboard their ship. It addressed Jack Robertson when he asked to speak to the Daleks' "boss". Although its appearance resembled that of a regular Dalek Drone, its deep voice, much like that of a Dalek Supreme, signified its rank. (TV: Revolution of the Daleks)

Behind the scenes
Archive footage of this Dalek was used to depict a representative of the ill-fated Dalek War Fleet addressing the Sontarans in The Vanquishers. In this instance, however, Nicholas Briggs provided a standard Dalek voice.
