  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 2003 summer conferences. Averages from $\Zzero$ resonance
results are derived for hadronic and leptonic cross sections, the leptonic
forward-backward asymmetries, the $\tau$ polarisation asymmetries, the $\bb$
and $\cc$ partial widths and forward-backward asymmetries and the $\qq$ charge
asymmetry. Above the $\Zzero$ resonance, averages are derived for di-fermion
cross sections and forward-backward asymmetries, photon-pair, W-pair, Z-pair,
single-W and single-Z cross sections, electroweak gauge boson couplings, W mass
and width and W decay branching ratios. Also, an investigation of the
interference of photon and Z-boson exchange is presented, and colour
reconnection and Bose-Einstein correlation analyses in W-pair production are
combined. The main changes with respect to the experimental results presented
in summer 2002 are updates to the mass of the W boson, four-fermion cross
sections and gauge couplings, all measured at LEP-2, and the LEP heavy-flavour
results measured at the Z pole.
  The results are compared with precise electroweak measurements from other
experiments, notably the recent final result on the electroweak mixing angle
determined in neutrino-nucleon scattering by the NuTeV collaboration and the
new result in atomic parity violation in Caesium. The parameters of the
Standard Model are evaluated, first using the combined LEP electroweak
measurements, and then using the full set of electroweak results.
