  Minimal Flavour Violation in its strong or weak versions, based on $U(3)^3$
and $U(2)^3$ respectively, allows suitable extensions of the Standard Model at
the TeV scale to comply with current flavour constraints in the quark sector.
Here we discuss considerations analogous to MFV in the context of
$SU(5)$-unification, showing the new effects/constraints that arise both in the
quark as in the lepton sector, where quantitative statements can be made
controlled by the CKM matrix elements. The case of supersymmetry is examined in
detail as a particularly motivated example. Third generation sleptons and
neutralinos in the few hundred GeV range are shown to be compatible with
current constraints.
