We study the minimal version of the supersymmetric standard model with spontaneous [ital CP] breaking. In this model, the Kobayashi-Maskawa matrix is real and contributions to [var epsilon] arise from box diagrams involving squarks. We analyze the region of the parameter space which corresponds to values for [var epsilon], [var epsilon][prime]/[var epsilon], and the neutron electric dipole moment (NEDM) in agreement with the experimental data. We show that the [ital CP]-violating phases must be of order 10[sup [minus]2] and the NEDM lies near its present experimental limit.
