  We consider a modification of the standard electroweak model with the third
quark generation and the $\tau$-lepton in vector representations of
$SU(2)\otimes U(1)_Y$ electroweak symmetry. This is a new way to implement
right-handed currents which are controlled by the usual Fermi constant, $G_F$,
the weak mixing angle, $\sin\theta_W$, and also by the right-handed mixing
matrices which survive when the Lagrangian density is written in terms of the
mass eigenstates. In this case there are also new CP violation phases.
