A scene from “Unfinished Business”

Louis Mountbatten: I'm getting a feeling that I've not had since Dieppe, that I'm walking into a trap.

Queen Elizabeth II: I'd like to think you had that sinking feeling on another occasion recently, when going to see your friends at the Bank of England. Is it even true?

Louis Mountbatten: Yes, I did go to lunch at the Bank of England to meet and listen to people who are horrified by what's happening to the country. A horror I hope you share.

Queen Elizabeth II: Perhaps. But conspiring with them is not the solution.

Louis Mountbatten: It is the beginning of a solution. Why are you doing this? Why would you protect a man like Wilson?

Queen Elizabeth II: I am protecting the Prime Minister. I am protecting the constitution. I am protecting democracy.

Louis Mountbatten: But if the man at the heart of that democracy threatens to destroy it, are we supposed to just stand by and do nothing?

Queen Elizabeth II: Yes. Doing nothing is exactly what we do, and bide our time, and wait for the people that voted him in to vote him out again, if indeed that is what they decide to do.
