  A $SU(3)_Q \times SU(3)_u \times SU(3)_d$ invariant scalar potential breaking
spontaneously the quark flavour symmetry can explain the standard model flavour
puzzle. The approximate alignment in flavour space of the vacuum expectation
values of the up and down `Yukawa fields' results as a dynamical effect. The
observed quark mixing angles, the weak CP violating phase, and hierarchical
quark masses can be all reproduced at the cost of introducing additional
(auxiliary) scalar multiplets, but without the need of introducing hierarchical
parameters.
