  This note presents a combination of published and preliminary electroweak
results from the four LEP collaborations and the SLD collaboration which were
prepared for the 2000 summer conferences. Averages from Z0 resonance results
are derived for hadronic and leptonic cross sections, the leptonic
forward-backward asymmetries, the tau polarisation asymmetries, the bbbar and
ccbar partial widths and forward-backward asymmetries and the qqbar charge
asymmetry. Above the Z0 resonance, averages are derived for di-fermion cross
sections and asymmetries, W-pair, Z-pair and single-W production cross section,
electroweak gauge boson couplings and W mass and decay branching ratios. The
major changes with respect to results presented in summer 1999 are final Z0
lineshape results from LEP, updates to the W mass and gauge-boson couplings
from LEP, and ALR from SLD. The results are compared with precise electroweak
measurements from other experiments. The parameters of the Standard Model are
evaluated, first using the combined LEP electroweak measurements, and then
using the full set of electroweak results.
