Sumario:High energy data from LEP are used to make precise measurements of parameters of the standard model, and to search for physics beyond it. W pairs are studied, enabling a number of independent measurements of the W mass and studies of W decays. Limits are presented for the masses of neutral and charged Higgs particles, while searches for supersymmetric particles have allowed significant regions of SUSY parameter space to be excluded. Lower limits on the masses of neutralinos, charginos, sleptons and squarks are presented, and supergravity and $R$-parity violating models are investigated.
