description The LHCb detector is one of the four large experiments collecting data at the LHC and is optimally designed to study Charge-Parity (CP) violation in beauty and charm hadrons. The LHCb collaboration has recently reported results from $B^0_s\rightarrow K^+K^-$ decays which show 4.0$\sigma$ evidence for time-dependent CP violation in the $B^0_s$ sector and measurements of the unitarity triangle angle $\gamma$ from $B^0_s\rightarrow D^{\mp}_sK^{\pm}$ decays, which are consistent with global fits from LHCb at 7 and 8 TeV. Measurements of CP violation in both $B^-\rightarrow D^-_{(s)} D^0$ and $D^0\rightarrow K^-\pi^+$ decays at 7 and 8 TeV show no evidence of CP violation while a combined measurement of $\Delta\textrm{A}_{\textrm{CP}}^{wgt}$ from $\Lambda_c^+\rightarrow ph^+h^-$ at 7, 8 and 13 TeV is also consistent with the hypothesis of CP conservation.
