[2] The early 1950s were a time of growing disagreements within the SPP, mainly centred on the question of the training of analysts.
[3] Despite wishing himself to avoid a split, Lacan was drawn into the dissident movement led by Daniel Lagache, as a result of his own separate dispute with the president Sacha Nacht over his practice of "short sessions".
Unfortunately, an unexpected by-product of the split was to deprive the new group, who termed themselves the Société Française de Psychanalyse (SFP), of membership of the International Psychoanalytical Association (IPA), to which they now had to seek out affiliation.
[10] Lacan refused such a condition and left the SFP together with many of its members in June 1964 to set up the EFP independently of the IPA.
The remaining membership of the SFP, including many of Lacan's own pupils such as Jean Laplanche, were to be recognised by the IPA the following year as part of a new body, the APF.
