  Recent topics regarding CP violation in heavy meson systems are discussed. As
an introduction, the status of the Unitarity Triangle fit and CP violation in B
meson mixing are briefly reviewed. Two topics are covered in more detail:
  Penguin pollution in the "golden mode" B_d to J/psi K has gained importance
due to the apparent smallness of new physics effects, together with the
outstanding precision expected from present and future collider experiments. A
very recent analysis is presented, which yields a stronger bound for the
maximal influence of penguin contributions than previous analyses and shows the
corresponding uncertainty to be reducible with coming data.
  Direct CP violation in hadronic charm decays received a lot of attention
lately, due to a measurement by the LHCb collaboration yielding an unexpectedly
large result. While this value is certainly not generically predicted in the
Standard Model, it might be possible to accommodate it nevertheless. Therefore
a method is discussed to use flavour symmetries to distinguish between this
possibility and new physics.
