  Results from heavy flavour electroweak physics at LEP1 are reviewed together
with measurements of 2-fermion processes at LEP2. For the former measurements
the emphasis is on analyses of heavy quark forward-backward asymmetries,
A_FB^b,c, and on the partial decay widths of the Z^0 to heavy quarks, R_b,c.
The measurements of the heavy quark asymmetries are used to extract the
effective electroweak mixing angle for leptons, sin^2(theta_eff^lept). A 2.9
sigma discrepancy between measurements of this quantity from A_l^SLD and from
A_FB^b is observed. The 2-fermion processes at LEP2 are used to place stringent
limits on physics processes beyond the Standard Model. However, all measured
quantities are in reasonable agreement with the Standard Model expectations,
and all calculated limits are well above the highest LEP2 center-of-mass
energies.
