We present a global re-analysis of the most recent experimental data on azimuthal asymmetries in semi-inclusive deep inelastic scattering, from the HERMES and COMPASS Collaborations, and in e{sup +}e{sup -} {yields} h{sub 1} h{sub 2} X processes, from the Belle Collaboration. The transversity and the Collins functions are extracted simultaneously, in the framework of a revised global analysis in which a new parameterisation of the unknown functions is also tested.
