  The left-right model is a gauge theory of electroweak interactions based on
the gauge symmetry SU(2)_R . The main motivations for this model are that it
gives an explanation for the parity violation of weak interactions, provides a
mechanism (see-saw) for generating neutrino masses, and has B-L as a gauge
symmetry. The quark-lepton symmetry in weak interactions is also maintained in
this theory. The model has many predictions one can directly test at a
TeV-scale linear collider. We will consider here two processes (e,e -> q, q,
barQ, barQ and e,e ->mu, nu, q, barQ) testing the lepton flavour violation
predicted by the model. We will also discuss constraints on supersymmetric
versions of the model.
