Radio, optical and infrared data are combined to study the nature of mJy-sources found in the 5C12 aperture-synthesis survey. The optical counterparts are QSOs, giant elliptical galaxies of the 3CR type, and blue galaxies. We find that the blue galaxies are a mixed group; the suggestion of a new blue population of evolving spirals at mJy levels is not supported by our data.
