The LHCb experiment has collected large samples of heavy flavoured hadrons during Run 1, corresponding to an integrated luminosity of 3.0 fb$^{-1} at $pp$ centre-of-mass energy of 7 and 8 TeV. This talk gives an overview of the CP violation measurements the LHCb collaboration performed using Run 1 data, with an emphasis on the latest measurements on the CKM angle $\gamma$ in a diverse range of decay modes. We also present the combination of all LHCb $\gamma$ related measurements, which is the most precise single experiment combination to date. Measurements are also presented of direct CP violation in D0 meson decays in LHCb, using the $\Delta A_{CP}$ technique as well as the recent LHCb measurement of the CP asymmetry in $B^0_{s}-\bar{B}^0_{s}$ mixing, $a_\mathrm{sl}^s$, using semileptonic $B^0_{s}$ and $\bar{B}^0_{s}$ decays, corresponding to the most precise measurement of this quantity to date.
