The computation of one-loop corrections to the \γ^\⋆ Q+ q and\ngR+g effective vertices in the framework of gauge-invariant effective theory\nfor Multi-Regge processes in QCD is reviewed. Due to consistent implementation\nof the "tilted Wilson line" regularization for rapidity divergences, the\ngauge-invariance has been preserved at all stages of calculation independently\non the rapidity regulator and cancellation of the power-like dependence on the\nregularization variable is traced. Only single-logarithmic rapidity divergence\nis left in the final result.\n
