Abstract
An alternative approach to the problem of CP-violation

is presented. It is based on the possibility of

spontaneous CP-breakdown in models with two Higgs doublets.

General features of the phenomenon such as stability of the

vacuum and the existence of a light axion are discussed.

We investigate the feasibility of spontaneously broken

CP in the minimal supersymmetric models - the MSSM and

NMSSM. The latter is shown to be experimentally viable.

The phenomenological implications of the model such as

CP-violating effects in the kaon systems and a nonzero

neutron electric dipole moment are studied.
