Abstract: As an addendum to our previous evaluation of the weak-interaction correctionsto hadronic top-quark pair production we determine the leading weak-interactioncontributions due to the subprocesses $b {\bar b} \to t {\bar t}$ and $g q{\bar q} \to t {\bar t} q {\bar q}$. For several distributions in $t {\bart}$ production at the LHC we find that these contributions are non-negligibleas compared to the weak corrections from the other partonic subprocesses.
