Flavour tagging, i.e. the inference of the production flavour of reconstructed $b$-hadrons, is essential for precision measurements of decay time-dependent CP violation and of mixing parameters in the the neutral $B$ meson systems. LHC's $pp$ collisions with their high track multiplicities constitute a challenging environment for flavour tagging and demand for new and improved strategies. We present recent progress and new developments in flavour tagging at the LHCb experiment, which will allow for a further improvement of CP violation measurements in decays of $B^0$ and $B_s^0$ mesons.
