Duke of Forgill
From Tardis Wiki, the free Doctor Who reference
The Duke of Forgill was a Scottish nobleman and the president of the Scottish Energy Commission. He was abducted by the Zygons and impersonated by Broton, their leader. The Doctor found the real Duke in the Zygon ship, along with the other abducted humans, and helped them escape prior to setting the ship to self-destruct. (DW: Terror of the Zygons)
