A status of precision measurements of electroweak observables at LEP is presented. The main improvements in 1995 are: final results from the 1993 lineshape scan and new preliminary results on the Z→b $$\bar b$$ partial width. All other measurements benefit from increased statistics. Progress was made on the calculation of the Bhabha cross-section, and on the estimate ofα(M Z 2 ). Finally, the top quark is now established and its mass measured directly. Agreement at the level of 10−3 is found for all purely leptonic or inclusive hadronic quantities with the SM predictions using the measured top mass.R b is measured to 0.8%; the preliminary average is 3.2σ away from the SM prediction.
