Precision tests of the electroweak interaction and the Higgs mass

The most relevant LEP electroweak measurements obtained during the LEP-I operation phase are briefly reviewed and their internal consistency as well as their agreement with the Minimal Standard Model predictions are discussed. Assuming the MSM, the precision LEP electroweak data together with other measurements performed at SLAC and FERMILAB allows already an interesting inference of the Higgs mass. (11 refs).
