Abstract
Results for the light meson mass spectrum from a Bethe-Salpeter approach are presented. The results obtained in the standard framework are Poincar\'{e} covariant and compare favourably with lattice results. Using a more sophisticated scheme, the pseudoscalar, vector and () axialvector charge eigenstate masses are unaltered whereas the () axialvector meson mass is raised.
