Here we propose models with $SU(2)_L\otimes SU(2)_R\otimes U(1)_{B-L}$electroweak gauge symmetry in which parity (or charge conjugation) is brokenexplicitly and the interactions of left- and right-handed fermions arecompletely different from each other at any energy scale. In these sort ofmodels there is no restoration of parity at high energies. However, as in allleft-right symmetric models, the electroweak charged interactions of quarks andleptons appear to be only left-handed at low energies, because the right-handedinteractions are suppressed by the mass of the respective charged vector bosonsand/or because these interactions may be much weaker than the left-handed ones.
