  In this talk, a unified model of scalar particles that addresses the flavour
hierarchies, solves the strong CP problem, delivers a dark matter candidate,
and radiatively triggers electroweak symmetry breaking is discussed. The
recently proposed axiflavon is embedded together with an (elementary) Goldstone
Higgs-sector in a single multiplet (and thereby also a model of flavour and
strong CP conservation for the latter is provided). Bounds on the axion decay
constant follow from requiring a SM-like Higgs potential at low energies and
are confronted with constraints from flavour physics and astrophysics. In the
minimal implementation, the axion decay constant is restricted to $f_a \approx
(10^{11}-10^{12})$ GeV, while adding right-handed neutrinos allows for a
heavy-axion model at lower energies, down to $f_a \sim 10$ TeV.
