A well-known question of Remeslennikov asks if finitely generated residually finite groups with free profinite completion are free. I will show that such groups should be residually nilpotent (and so, parafree). I will also show that the same conclusion holds for finitely generated residually-(finite soluble) groups with free prosoluble completion.
