[en] We extend a previously developed description of the flavour parameters in the 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 large mixing angle θ_μτ and a large hierarchy in the neutrino squared mass differences. A unified description of quark and lepton masses and mixings emerges. The neatest quantitative predictions are for elements of the unitary mixing matrix in the lepton sector vertical bar V_μl^l vertical bar = ((V_e3^l)/(V_μ3^l)) = ((V_e2^l)/(V_τ3^l)) = √((m_e)/(m_μ)), which go together with the analogous relations in the quark sector ((V_ub^q)/(V_cb^q)) = √((m_u)/(m_c)), ((V_td^q)/(V_ts^q)) = ∝((m_d)/(m_s))
