$CP$ violation in charm and beauty decays at LHCb

LHCb is a dedicated heavy flavour physics precision experiment at the LHC searching for New Physics (NP) beyond the Standard Model (SM) through the study of very rare decays of beauty and charm-flavoured hadrons and precision measurements of $CP$-violating observables. In this review I will present a selection of recent precision measurements of $CP$-violating observables in the decays of beauty and charm-flavoured hadrons. These measurements are based on an integrated luminosity of up to 1.0 fb$^{-1}$ collected by LHCb in 2011.
