The tree-level measurement of the CKM angle γ is one of the most important tests of CP violation in the Standard Model. Discrepancies between measurements in tree-level decays and decays with loops might provide evidence of physics beyond the Standard Model. Results of the recent analysis of B0 → D0K∗0, B0s →D±s K±π±π∓, B± → D h± and B− → D∗K− decays are presented in this paper. A newcombination of all LHCb measurements is also discussed. The achieved precision of the LHCb result, γ = (67 ± 4)◦, dominates the worldaverage.
