Query: Problem of flavour in SUSY GUT and horizontal symmetry   The concept of non-abelian horizontal symmetry $SU(3)_H$ can greatly help in
understanding the fermion and sfermion flavour structures in supersymmetric
grand unification. For the sake of demonstration the $SU(5)\times SU(3)_H$
model, suggested earlier in ref. \cite{PLB85}, is revisited. We show that under
very simple and natural assumption it links the sfermion mass pattern to those
of fermions in a remarkable way. All dangerous supersymmetric flavour-changing
contributions are naturally suppressed in a general case, independently of the
concrete texture for fermion mass matrices. Nevertheless, within this framework
we present an example of predictive model for fermion masses and mixing, which
leads to 7 consistent predictions for the low energy observables. [Based on
