We present observations of a candidate gravitational lens system behind the Fornax dwarf spheroidal galaxy, at z=1.406 with a separation of 6.1 arcsec. The rest-frame velocity difference between the two components (from broad emission lines) is consistent with zero. The emission lines have similar strength in both components and show strong similarities. The continuum in component A, however, is ~=50 per cent brighter than in component B, and slightly bluer. The differences between the spectra can be accounted for by time-delay and/or microlensing effects, and the similarities between the spectra argue for a gravitational lens nature to the system.
