  We provide evidence that the gauge-fermion interaction in multiflavour
quantum electrodynamics in $(2 + 1)$-dimensions is responsible for non-fermi
liquid behaviour in the infrared, in the sense of leading to the existence of a
non-trivial (quasi) fixed point (cross-over) that lies between the trivial
fixed point (at infinite momenta) and the region where dynamical symmetry
breaking and mass generation occurs. This quasi-fixed point structure implies
slowly varying, rather than fixed, couplings in the intermediate regime of
momenta, a situation which resembles that of (four-dimensional) `walking
technicolour' models of particle physics. Connection with the anomalous
normal-state properties of certain condensed matter systems relevant for
high-temperature superconductivity is briefly discussed. The relevance of the
large (flavour) N expansion to the fermi-liquid problem is emphasized.
