description <!--HTML--><p>The angle gamma&nbsp;is the least constrained parameter in the CKM unitarity triangle. Its determination in decays induced by tree-level b -&gt; u&nbsp;transitions is largely unaffected by potential new physics contributions. This allows for a consistency check of the unitarity triangle, but also of comparisons with gamma&nbsp;determinations from modes with loop-diagrams. We present here a new precise determination of gamma&nbsp;using a time-dependent flavour-tagged analysis of B<sub>s</sub> -&gt;&nbsp;D<sub>s</sub> K&nbsp;decays with the LHCb experiment. New developments in flavour tagging are presented.</p>
