Influence on the Doctor
The Doctor visited Great Britain more than anywhere else on their travels. He developed a great affinity for it and even lived there for some time. (TV: "An Unearthly Child", et al.)

(TV: The Day of the Doctor) He accepted a British knighthood from Queen Victoria, (TV: Tooth and Claw) and, in his fifth incarnation, an English knighthood from an imposter posing as King John. (TV: The King's Demons)
