Speaking to Radio Times, Davies said: "John Simm's incarnation of The Doctor's nemesis is thoroughly contemporary. Previous Masters seemed to appear on a whim, merely to thwart The Doctor with a throaty cackle."
Referring to the character disguising himself as politician Harold Saxon, Davies added: "The moment I thought of having an evil Prime Minister, I thought, 'That's the key to it!' How much fun would The Master have in that role?"
