Abstract. I present a detailed and complete calculation of the gluino and neutralino contribution to the direct CP violating parameter <varepsilon>' within the MSSM. I include the complete mixing matrices of the neutralinos and of the scalar partners of the left and right handed down quarks. I find that the neutralino contribution is generally small but can be larger than the gluino contribution for small values mS\leq400 GeV of the supersymmetric breaking scale.
