It’s quite common to hear the phrase “this event will be run under Chatham House Rules”. The meaning of the phrase is that what is said in the room should be not be attributed to anyone present.

Chatham House is an independent policy institute and a trusted forum for debate and dialogue.

But they only have one rule. This is how it’s described on their website:

“When a meeting, or part thereof, is held under the Chatham House Rule, participants are free to use the information received, but neither the identity nor the affiliation of the speaker(s), nor that of any other participant, may be revealed.”

I can be a bit of a pedant, and I couldn’t help myself pointing it out today. Yes, I really am that much fun to work with. I will try to do better in future…
