From the following text I understand it is possible to say "London Manners" or "French Manners". I am not sure if this would work; depends on the context and how explicit you want the translation to be. This term could work because it is vague and open enough to project different notions on it. The government aspect is perhaps not so clear in this option.

"Edwin's incestuous desires are compounded, occurring with his sister too: After Whitmore seduces her, she miscarries and takes up with his friend Hartford once Edwin kills Whitmore in a duel. Edwin takes up with Mrs Whitmore in Paris, who is said to have 'French manners,' although everything in this novel suggests her manners and behavior might better be called 'London manners', since all the characters associated with London share her manners, behavior, and attitudes."
