CP violation in D decays

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 $D^0 \to π^-π^+$ 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 $D^0 \to K^0_S π^0$, $D^0 \to K^0_S η^{(\prime)}$, $D^+_{(s)} \to ϕπ^+$ and $D^+ \to π^+ η^{(\prime)}$, is also presented. Finally, results obtained by CDF with $D^0 \to K^0_S π^+π^-$ decays, as well as by LHCb and BaBar with other multi-body $D$ decays, are shown.
