  In light of recent results from the LHC, MEG and neutrino experiments, we
revisit the issue of charged lepton flavour violation (LFV) in supersymmetric
theories with massive neutrinos, where flavour-violating soft
supersymmetry-breaking masses for sleptons are induced naturally by radiative
corrections. We link our results to the expectations for neutrino mixing angles
in SU(5) enhanced by an abelian flavour symmetry, with particular focus on
$\theta_{13}$. We focus on the radiative decays $\ell_i \rightarrow \ell_j
\gamma$ and on detection prospects at the LHC and a linear collider (LC). We
use supersymmetric parameters consistent with cosmological considerations and
with LHC searches for supersymmetry and the Higgs mass. We find a class of
scenarios where the LHC may be sensitive to LFV sparticle decays and LFV
processes could be detectable at a LC with centre-of-mass energy above 1 TeV,
whereas LFV lepton decays may be suppressed by cancellations in the decay
amplitudes.
