The Chatham House Rule originated at Chatham House with the aim of providing anonymity to speakers and to encourage openness and the sharing of information. It is now used throughout the world as an aid to free discussion.
The Chatham House Rule reads as follows:
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.
The world-famous Chatham House Rule may be invoked at meetings to encourage openness and the sharing of information.

Explanation of the Rule
Meetings do not have to take place at Chatham House, or be organized by Chatham House, to be held under the Rule.
Meetings, events and discussions held at Chatham House are normally conducted 'on the record' with the Rule occasionally invoked at the speaker's request. In cases where the Rule is not considered sufficiently strict, an event may be held 'off the record'.

Q. Can I 'tweet' while at an event under the Chatham House Rule?
A. The Rule can be used effectively on social media sites such as Twitter as long as the person tweeting or messaging reports only what was said at an event and does not identify - directly or indirectly - the speaker or another participant. This consideration should always guide the way in which event information is disseminated - online as well as offline.
