Tests of lepton flavour universality inBdecays offer an excellent opportunity to test the Standard Model, and show hints of new physics in analyses performed by the LHCb, Belle and BaBar experiments. Several theoretical models proposed to explain possible violation of lepton flavour universality claim a connection with lepton flavour violation inBdecays. These proceedings review the experimental status of the tests of lepton flavour universality and the searches of lepton flavour violation inBdecays.
