Abstract	The latest results of the CKM angle $\gamma$ combination are presented for the 2020 LHCb Implications Workshop. New and updated inputs from $B^+ \to Dh^+$ ($D\to h^+h^-$), $B^+ \to Dh^+$ ($D \to K^0_{\rm S} h^+h^-$), $B^+ \to Dh^+$ ($D \to K^0_{\rm S} K^+ \pi^-$), $B^+ \to D^*h^+$ ($D\to h^+h^-$), $B^0 \to D K^{*0}$ ($D\to h^+h^-$ and $D\to h^+\pi^-\pi^+\pi^-$) and $B^0_s \to D^\mp_s K^\pm \pi^\mp \pi^\pm$ ($D^+_s \to h^+ h^- \pi^+$) decays are included, where $h = K$ or $\pi$. The new combination gives $\gamma = (67\pm4)^\circ$, where the uncertainty includes both statistical and systematic effects.
