  We review the most precise tests of the CKM model of flavour physics
performed by the LHCb collaboration during the current year. These include
world best measurements of both time-dependent and time-independent $C\!P$
violation in charm decays, the first observation of a nonzero mass difference
of the neutral charm-meson eigenstates, and the most precise determination to
date of the mass difference between the $B_s^0$ eigenstates. A new simultaneous
combination of measurements of the CKM angle $\gamma$ and of charm decays
allows to improve the precision on the decay-width difference of the neutral
charm-meson eigenstates by a factor of 2 with respect to the combination of
charm results only and to reach the best precision on $\gamma$ from a single
experiment. The precision of the measurements is mainly limited by statistics,
so further improvement is expected in the future.
