  Recent developments concerning CP violation beyond the Standard Model are
reviewed. The central target of this presentation is the $B$ system, as it
plays an outstanding role in the extraction of CKM phases. Besides a general
discussion of the appearance of new physics in the corresponding CP-violating
asymmetries through $B^0_q$--$\bar{B^0_q}$ mixing $(q\in\{d,s\})$, it is
emphasized that CP violation in non-leptonic penguin modes, e.g. in $B_d\to\phi
K_{S}$, offers a powerful tool to probe physics beyond the Standard Model. In
this respect $B\to\pi K$ modes, which have been observed recently by the CLEO
collaboration, may also turn out to be very useful. Their combined branching
ratios allow us to constrain the CKM angle $\gamma$ and may indicate the
presence of physics beyond the Standard Model.
