  We study the localization properties of the low-lying Dirac eigenmodes in QCD
at imaginary chemical potential $\hat{\mu}_I=\pi$ at temperatures above the
Roberge-Weiss transition temperature $T_{\rm RW}$. We find that modes are
localized up to a temperature-dependent "mobility edge" and delocalized above
it, and that the mobility edge extrapolates to zero at a temperature compatible
with $T_{\rm RW}$. This supports the existence of a strong connection between
localization of the low Dirac modes and deconfinement, studied here for the
first time in a model with a genuine deconfinement transition in the continuum
limit in the presence of dynamical fermions.
