We analyse a generic model based on an $SU(3)$ family symmetry providing a full description of quark and lepton masses and mixing angles. We show that a precise fit of these fermion textures is consistent with CP being spontaneously broken in the flavour sector. We reproduce the observed results of the Jarlskog invariant in the quark sector CP violation. Furthermore, our model predicts the CP violation to be expected in the neutrino sector and in the Supersymmetric sector we control the flavour structure of the SUSY soft breaking terms. Therefore, this approach solves both the Supersymmetric CP and flavour problems.
