  Lepton charge asymmetries can be used as an alternative means of searching
for new physics. They are interesting because they are small in the Standard
Model and therefore, necessarily evidence new physics. In this work we explore
the use of lepton asymmetries as a probe of the flavour structure of the
left-right symmetric model with spontaneous CP violation. We find that new
physics may enhance the magnitude of $a_{SL}$ up to the precent level within
the appropiate parameter space.
