We present a new model of the lepton sector that uses a family symmetry A4 to make predictions for lepton mixing which are invariant under any permutation of the three flavours. We show that those predictions broadly agree with the experimental data, leading to a largish sin^2(theta12) >~ 0.34, to |cos(delta)| >~ 0.7, and to | 0.5 - sin^2(theta23) | >~ 0.08; cos(delta) and 0.5 - sin^2(theta23) are predicted to have identical signs.
