The LHCb collaboration has provided many results related to the DISCRETE conference topic. Namely, these concern $CP$ violation in beauty and charm meson decays as well as in baryon decays and searches for lepton flavour violation. This work is focused on some of the latest measurements of the $CP$ violation, listing the following analyses: $\sin{2\beta}$ in $B \to \psi K^0_S$, CKM angle $\gamma$ measurement's in $B^{\pm} \to D^*h^{\pm}$, $B^{\pm} \to DK^*(892)^{\pm}$ and $B^0 \to DK^*(892)^0$, search for $CPV$ in $D^+\to K^-K^+\pi^+$, evidence for $CPV$ in baryon decays, and in beauty to charmonium reaction.
