### Description

Recently, LHCb has confirmed the evidence for lepton flavour universality violation in the $R_K$ ratio with 3.1$\sigma$ significance. We present new physics implications within a model-independent approach and make projections for future measurements that indicate that LHCb will be in the position to discover lepton non-universality with the Run 3 data in a single observable. We also present other ratios which are able to differentiate between various new physics scenarios in the near future. Moreover, we present global fits of rare $B$-decays within multidimensional fits involving up to all the relevant 20 Wilson coefficients and compare different scenarios via likelihood ratio tests, applying Wilks’ theorem.
