Rare b→sμ+μ– transitions that proceed via flavour changing neutral currents are suppressed in the SM and provide a sensitive probe of new physics contributions entering in competing diagrams. The dataset collected with the LHCb experiment has enabled measurements to be made in decays such as B→K*0μ+μ–, B+→K+μ+μ– and Bs→φμ+μ–. Particularly interesting are the angular and isospin asymmetries in the decay B→K(*)0μ+μ–, which are sensitive probes of new physics. The large statistics of reconstructed B mesons allow, for the first time, experimental access to b→dμ+μ– transitions, such as B+→π+μ+μ–, which are further suppressed in the SM. The latest results on these decay modes will be presented.
