Query: Minimal lepton flavour structures lead to non-maximal 2-3 mixing   Present data prefer a large but non-maximal 2-3 mixing in the lepton sector.
We argue that this value, in connection with $\sin\theta_{13}\simeq 0.15$, is
the generic outcome of minimal flavour structures. We present a few different
incarnations of this statement, in terms of lepton mass matrices depending on a
small number of parameters, that can be justified by discrete flavour
symmetries. We also propose a general procedure to study the correlation
between $\theta_{23}$, the absolute scale and ordering of the neutrino masses,
and the leptonic CP-violating phases.
