We extend a previously developed description of the flavour parameters in t
he charged fermion sector, based on a U(2) flavour symmetry, to include two
main features of the neutrino sector seemingly implied by recent data: a l
arge mixing angle theta(mu tau) and a large hierarchy in the neutrino squar
ed mass differences. A unified description of quark and lepton masses and m
ixings emerges, The neatest quantitative predictions are for elements of th
e unitary mixing matrix in the lepton sector
[GRAPHICS]
which go together with the analogous relations in the quark sector
