The controversial discussions were a protracted series of meetings of the British Psychoanalytical Society which took place between October 1942 and February 1944 between the Viennese school and the supporters of Melanie Klein. They led to a tripartite division of training in the society after the war with the three groups of Kleinians, Anna Freudians, and the Middle (or later Independent) Group. It was agreed further that all the key policy making committees of the BPS should have representatives from the three groups.
