  We briefly review the question of spontaneous CP violation in some models of
weak interactions. The next-to-minimal supersymmetric standard model, with two
Higgs doublets and one gauge singlet, is one of the minimal extensions of the
standard model where SCPV is viable. We analyse the possibility of spontaneous
CP violation in the next-to-minimal supersymmetric standard model with an extra
singlet tadpole term in the scalar potential, and confirm the existence of
phenomenologically consistent minima with non-trivial CP violating phases.
