Standard galaxy formation models predict that large-scale double-lobed radio sources , known as DRAGNs , will always be hosted by elliptical galaxies .
In spite of this , in recent years a small number of spiral galaxies have also been found to host such sources .
These so-called spiral DRAGNs are still extremely rare , with only \sim 5 cases being widely accepted .
Here we report on the serendipitous discovery of a new spiral DRAGN in data from the Giant Metrewave Radio Telescope ( GMRT ) at 322 MHz .
The host galaxy , MCG+07-47-10 , is a face-on late-type Sbc galaxy with distinctive spiral arms and prominent bulge suggesting a high black hole mass .
Using WISE infra-red and GALEX UV data we show that this galaxy has a star formation rate of 0.16-0.75 M _ { \odot } yr ^ { -1 } , and that the radio luminosity is dominated by star-formation .
We demonstrate that this spiral DRAGN has similar environmental properties to others of this class , but has a comparatively low radio luminosity of L _ { 1.4 GHz } = 1.12 \times 10 ^ { 22 } W Hz ^ { -1 } , two orders of magnitude smaller than other known spiral DRAGNs .
We suggest that this may indicate the existence of a previously unknown low-luminosity population of spiral DRAGNS .
