I discuss the preliminary results of the LEP experiments ALEPH, DELPHI, L3, and OPAL on the rare Z decays. Limits of about 105I[minus]5 on the branching ratios are reported by most experiments. The question of excess in the [tau][tau]V final state remains unsettled. From the analysis of the L3 data the ZZ[prime] mixing angle is confined to [plus minus]1.5[degree] for most extensions of the Standard Model of electroweak interactions.
