Battle of Ideas
It commenced in 2005  and is an annual two-day debating event held in London. It claims it "makes virtues of free-thinking and lively exchanges of views" and "fosters an atmosphere of intellectual freedom and open-ended exploration of new ideas, research and social trends". In practice, all of the sessions' chairs, around half of the speakers and most of those selected by the chair to contribute from the floor are LM associates. In response to the question, "Is the Institute of Ideas committed to promoting debate or to promoting one side of a debate?", Claire Fox replied "We are committed to debating in general, but make it perfectly clear that we have a position in the debates we organise."  Accounts by attendees are here.
