We analyse the electric dipole moment of the neutron in the MSSM, induced by the renormalisation of the soft-SUSY breaking terms. We run the RGEs using two-loop expressions for gauge and Yukawa couplings and retaining family dependence. The μ and B parameters were determined by minimising the full one-loop Higgs potential, and we find that the neutron EDM lies in the range 10 −33 < | d n | < 10 −29 e cm.
