Query: B-anomalies related to leptons and lepton flavour violation: new
  directions in model building   B-decays mediated by both charged currents and neutral currents have provided
hints of violation of lepton flavour universality. By assuming an explanation
of these anomalies in terms of new physics at the TeV scale affecting the third
fermion generation, we review the relevant constraints. In particular we
illustrate the effects of electroweak radiative corrections and their impact on
a consistent interpretation of the data. The simplest scenario is ruled out and
we briefly discuss the modifications required to simultaneously describe the
whole set of anomalies.
