Query: Spontaneous CP Symmetry Breaking at the Electroweak Scale   We present a top-condensation model in which the CP symmetry is spontaneously
broken at the electroweak scale due to the condensation of two composite Higgs
doublets. In particular the CP-violating phase of the CKM matrix is generated.
A simpler model where only one quark family is included is also discussed. In
this case, for a general four-fermion interaction ($G_{tb}\neq 0$), the
particle spectrum is the one of the one Higgs doublet model.
