Yes, Minister, Series Three (1982)

[Hacker, Humphrey and Chief Whip Jeffery are talking about Hacker's campaign on Prime Ministership ]

Hacker:
But supposing somebody would say "Does that mean you refuse to stand?" You know how these media people try to trap you.

Sir Humphrey:
Well, Minister, it's not my place, but on previous occasions, a generally acceptable answer has been "While one does not seek the office, one has pledged oneself to the service of one's country. And if one's friends were to persuade one that that was the best way one could serve, one might reluctantly have to accept the responsibility, whatever one's own private wishes might be."

Hacker:
[taking notes] "...private wishes might be." yes, I think I've got that.
