  First evidence for $C P$ violation in two-body singly Cabibbo-suppressed
decays of $D^0$ mesons reported by LHCb has recently aroused great interest in
charm physics. In this document the latest measurements of $C P$ violation in
the charm sector are discussed. LHCb and CDF results on time-integrated $C P$
asymmetries in $D^0 \to \pi^-\pi^+$ and $D^0 \to K^-K^+$ decays are presented
in some detail. A search for $C P$ violation performed by Belle in other
two-body decays, namely $D^0 \to K^0_S \pi^0$, $D^0 \to K^0_S \eta^{(\prime)}$,
$D^+_{(s)} \to \phi \pi^+$ and $D^+ \to \pi^+ \eta^{(\prime)}$, is also
presented. Finally, results obtained by CDF with $D^0 \to K^0_S \pi^+\pi^-$
decays, as well as by LHCb and BaBar with other multi-body $D$ decays, are
shown.
