  We formulate the first order corrections to processes involving the
scattering or annihilation of quarks in a form in which the QCD and electroweak
parts are exactly factorised. This allows for a straightforward physical
interpretation of effects such as lepton-hadron correlations, and a simpler
Monte Carlo treatment. The postscript file for this paper can also be obtained
