We study the implications of a successful leptogenesis within the frameworkof Minimal Lepton Flavour Violation combined with radiative resonantleptogenesis and the PMNS matrix being the only source of CP violation, whichcan be obtained provided flavour effects are taken into account. We find thatthe right amount of the baryon asymmetry of the universe can be generated underthe conditions of a normal hierarchy of the light neutrino masses, anon-vanishing Majorana phase, sin(theta_{13})>0.13 and m_{nu,lightest}<0.04 eV.If this is fulfilled, we find strong correlations among ratios of charged LFVprocesses.Comment: published in JHEP, small change
