  CP violation in K and B decays is reviewed in the Standard Model (SM) and
beyond the SM. In K decays, one is seeking first evidence for CP violation in
direct $K\to \pi\pi$ decays. This would not give a precise quantitative test
for the present explanation of CP violation in terms of a phase in the
Cabibbo-Kobayashi-Maskawa (CKM) matrix. Such tests are provided by a variety of
CP asymmetries in neutral and charged B decays. Certain features,
characterizing CP violation beyond the standard model, are outlined in the B
meson system.
